After 2 years of extensive research, design, engineering and testing, Metal-Era is launching Eliminailer-T as an alternative to wood nailers.
More than half of roof failures recorded are attributed to the roof’s perimeter. While Metal-Era prides itself on longevity, durability and performance at the edge, we know that failures in the industry often occur due to wood nailers that have rotted, cracked or split, been improperly installed, or have been infected with disease or insects. Pressure treated wood adds to the concern by infusing chemicals into the wood that can cause fastener corrosion and deterioration over the life of the roof.
Metal-Era wanted to provide an option that addressed these issues and more.
Eliminailer-T is the next generation in roof edge systems. The patented design is extruded from a heavy gauge aluminum that will not warp, crack, split or rot. Eliminailer-T can be installed directly onto the building’s substrate or an existing nailer – if structurally stable – and allows insulation to be brought fully to the edge of the building, increasing structural and thermal performance.
A Metal-Era time study revealed that Eliminailer-T installs up to 60% faster than adding two wood nailers - saving time, labor and energy. And because it is a heavy gauge extruded aluminum, each 12’ section is as straight the day it is installed as the day it was produced. Eliminailer-T also stacks easily for storage and transportation, making it as simple to get on the roof as it is to install.
Eliminailer-T has been tested, and meets requirements for FM 1-49. In fact, an independent ANSI/SPRI/FM 4435/ES-1 test at FM resulted in Eliminailer-T being able to withstand greater than 999 PSF at the corner region. In recognition of the product’s long-term strength, Metal-Era is supporting Eliminailer-T with a Lifetime Limited 215 MPH Wind Warranty.
Providing long-term structural and thermal performance, quick and easy installation, and an unmatched warranty in the industry, Eliminailer-T provides a high performance alternative that could conceivably change how roofs are forever constructed.

Anchor-Tite Extended Fascia with Fascia Extender
Within a year of installing another company’s fabricated fascia, the building owner of Barber Law Firm was highly dissatisfied with its performance. The appearance of the fascia was distorting and warping. Often referred to as “oil canning,” it is one of the most common roof edge problems encountered in the market and is completely avoidable.
Seeking a better long-term solution for his building investment, the building owner began working with CSL Materials in TX to remedy the problem. With a low slope, tiered contemporary roofing design situated in a high velocity wind area, this Texas law firm needed a strong, high performance roof edge solution. Plus, the law firm required very tall face heights to cover its varying roof tiers.
The existing fascia was built of an insufficient gauge material and installed in a manner ill-equipped for face heights over 8” to properly withstand wind forces and thermal expansion. The result was rapid deterioration and oil canning of the fascia cover. This combination left the law firm’s roof edge extremely vulnerable to disengagement, and over time could lead to failure.
Awareness around the importance of protecting the roof edge is gaining momentum. It’s not just hurricanes and tornadoes that cause great damage. It’s the accumulation of all wind and weather events that batter a roof day after day that can cause significant reduction in performance. The edge, especially at the corners, takes the brunt of hurdling wind and rain events. A single less severe weather event can serve as the final straw for roof edge failure.
At least 60% percent of roof failures begin at the roofs edge with causes ranging from insufficient gauge material and roof edge products ill-suited for the application to improper installation. Sometimes it’s a combination of factors. For many, roof edge is at the bottom of the list of purchase decisions and sacrifices are made when value engineering a project. Yet roof edge is a crucial roof decision. If chosen carefully, it’s the 1% of construction cost that protects 100% of the roof investment… for decades.
The Action Plan:
CSL Materials partnered with Paul Booher, Metal-Era’s Southern Field Tech, to take detailed field measurements and assess wind requirements and performance needs for the law firm. Paul worked with Metal-Era’s Technical Support Team to create an action plan and determine the best product approach to meet building code, satisfy the regions rigorous wind standards, and create a visually appealing finished look to complement the building’s design.
Recommended for this project was Metal-Era’s high performance Anchor-Tite Extended Fascia, designed and tested to meet ANSI/SPRI/4435/ES-1 standards. This product was provided in custom face heights to adapt to building conditions. The Anchor-Tite Fascia system is built for longevity and offers superior performance against oil canning, weather events, and wind forces by protecting the roof investment with its 215-mph lifetime wind warranty.
Anchor-Tite Extended Fascia with Fascia Extender
The Metal-Era Difference:
- 258 LF of Anchor-Tite Extended Fascia in .050 Aluminum, color Dark Bronze with a Kynar finish (30 year warranty).
- The Anchor-Tite Fascia System includes heavy gauge extruded anchor bar for terminating the membrane, continuous cleat, splice plates, and a cohesive cover in 12’ lengths, saving on labor as 12’ lengths install 20% faster than 10’ lengths.
- The Anchor-Tite Extended Fascia was custom fabricated to specific sizes for each roof tier of the Law Firm.
- Upper roof – 19.5” comprised of 9 ¾” custom Anchor-Tite Extended Fascia and 9 ¾” Flush Face Fascia Extender
- Lower roof – 17.5” comprised of 8 ¾” custom Anchor-Tite Extended Fascia and 8 ¾” Flush Face Fascia Extender
- Metal-Era’s concealed splice plates are specially designed to prevent migration under the fascia panels and create a more aesthetically pleasing finish compared to traditional cover plates. Also included were custom soffit J closures pre-manufactured by Metal-Era.
Metal-Era’s hands-on support makes the process easier for contractors, saving them time and money to get them onto the next roof faster. On this project, the Metal-Era team assisted the roofing contractor who hadn’t used Anchor-Tite Extended Fascia by walking him through the install and answering questions for fast and successful completion. Our team offered solutions when the preexisting fascia was removed to find there was no underlayment on the wood nailer.
Metal-Era takes pride in its team approach. From meetings with the owner and contractor to facilitating project takeoffs and providing in-field assistance, the Metal-Era team and CSL Materials provided a full spectrum of project support. The Metal-Era difference is in its comprehensive customer-centric system ensuring customer needs are met, solutions are proactive, and accurate installation is achieved.

Offsite construction has grown in recent years due to the changing landscape of the construction industry. Building away from the construction site allows for more work to be done to the building itself while simultaneously getting other parts of the building finished. The more work that can be accomplished offsite, the more time can be saved on the project. As deadlines become shorter, budgets tighten, and the skilled labor pool continues to shrink, offsite construction will continue to be the answer to some of the issues that the construction industry is currently facing.
Brad Van Dam, Vice President of Sales at Metal-Era says, “We’ve witnessed a growing trend among roofing and sheet metal contractors over the past five years, who are regularly incorporating pre-manufactured roof edge into their business model, as a supplement to their own sheet metal shops. They’re finding it helps move them onto their next roofing project faster, optimizing their limited labor force, and customers are realizing tangible cost savings.”
Prefabricated products are engineered with the installer in mind. Being able to quickly install entire sections or pieces of a building helps contractors finish projects faster. Prefabricated products come in a variety of price points based on many factors, including whether standard product options are chosen or if custom fabrication is needed. Prefabricated products allow contractors to take on more jobs as well as save on labor costs. The time and cost savings related to offsite and prefabricated construction helps improve margins. A contractor might pay more up front for a prefabricated product but save far more in labor expenses on a project, achieving greater profits.
Van Dam continues, “Prefabrication and modular construction is not new, it’s logically expanding to address labor shortages. Enabling contractors to reduce their inventory, increase cash flow, and shift labor to installation and supervisory roles from fabrication is a substantial benefit that many owners consider. Combine these financial benefits with the assurance of knowing this critical component will meet building codes and local wind uplift requirements, and it is very rewarding for all stakeholders.”
Quality control and consistency are more reasons offsite construction is gaining popularity. When products are fabricated in a controlled environment with multiple quality check points, products are more likely to arrive to the jobsite ready to install without defects. On site construction is reliant on the schedule and expertise of the contractors working on the project.
“We work alongside contractors every day who supply sheet metal products yet integrate pre-manufactured roof edge into their lineup because it keeps projects on schedule and allows them to easily meet building codes and install the edge faster with a smaller crew,” adds Van Dam. “Plus, pre-manufactured roof edge offers contractors more options that are not easily shop fabricated.”
Currently, only one person is entering the construction workforce for every five retiring. This skilled labor shortage will continue to drive construction cost up while diminishing the amount of experience in the work force. With prefabrication, experienced crews work with precise equipment to make a quality and consistent product, every time. Many prefabricated products are designed and tested to meet rigorous building codes, offer more robust warranties than shop fabricated products, deliver greater long term performance, and simplify the installation process.
As innovations in technology continue to shape the construction industry, these advancements will expedite the construction process and bring more consistency in building products resulting in greater longevity. These innovations and process improvements will also be instrumental in alleviating some of the difficulties brought on by the labor shortage, while still increasing profitability. Future success and profitability in the construction industry will come from growing integration of prefabricated components, increased collaboration and discussion, and openness to adapt.

Renovated Apartment Complex with Shared Green Roof, Deck, and Patio in Philadelphia, PA
Topline Construction – Philadelphia
Exterior Building Solutions
Custom Perma-Tite Coping
Metal-Era was selected as the coping manufacturer for this highly custom apartment complex roof edge project. The multi-use roof included a pergola with wooden posts coming up through the coping to support the structure, covering 80 percent of the roof perimeter.
A continuous coping with standard miters was not an option. There were many challenges and difficult details on the project with posts coming up through the substrate. Plus, distance between the posts was not uniform, from post to post or section to section. In fact, some corners had no posts while others had two. This called for the roof edge to be measured and built by section to effectively accommodate the posts. With each corner having varying needs, custom miters were required.
The Action Plan:
As value to the customer, James McGlade, Metal-Era’s Northeast Technical Manager, started by conducting an in-depth field measurement of the entire roof, recording variations and install challenges while determining the best product recommendation. He developed a list of problems to be overcome during install so solutions were prepared proactively. James worked with the Director of Product Development to create a detailed action plan by roof section to accomplish a seamless coping install ensuring every piece would work together effectively.
From there, Metal-Era’s engineering team created detailed CAD drawings for the plant to use in accurately fabricating all of the products needed for this custom application. Engineering held a preplanning meeting with the plant to walk through prior to production. The CAD department also developed custom print approvals and custom installation instructions totaling 10-pages to guide accurate install.
Throughout the project, James coordinated and communicated with all parties to ensure success from field measurement through final install. James met with the Topline Construction installer to go through the detailed instructions, answering questions, and connecting with a Metal-Era Process Engineer when needed so the installation went extremely smooth. Not one piece needed to be remade.
This project consisted of many custom pieces including:
- Custom Perma-Tite Coping, flat-coping without nailer, in matte black with Kynar finish (30 year warranty) fabricated to accommodate each set of posts.
- Custom Concealed Splice Plates built wider up to 24” with adapter to fill longer gaps for versatile in-field installation while allowing use of 2 anchor clips per plate for security. Plus an increased number of splice plates were used to seamlessly
complete the coping installation.
- Custom Anchor Clips with Risers were made to height match existing roof conditions. A hat channel was added to act as a brace for the anchor clip allowing desired height and stability to be achieved.
- A variety of Custom Miters were created to complete this project. Some miters came in two pieces and were able to be riveted onsite for accurate install around two posts creating an exact fit at the corners. Other miters were premanufactured as a single piece measured to fit the unique measurements between posts.
"I’ve used Metal Era a few times before and on this project I knew I had to find a source to give me a prefabricated engineered solution. Metal Era came out and performed detailed measurements and helped with the install so not only did I have an excellent finished product, my install time was fast. I plan to use Metal Era more in the future."
--Scott Manley, Topline Construction
The Metal-Era Difference
This was an effective whole team approach with superior communication built in. Beginning with the rep firm, Exterior Building Solutions, identifying the project needs and connecting with James, Metal-Era’s Field Tech Manager, to assess and conduct
a detailed field measurement on this complex project set everyone up for success. Then, James collaborated with Metal-Era’s engineers and product development team to construct a solution-oriented custom plan. Production was seamless. Metal-Era anticipated extra materials to account for pre-determined in-field alterations. And finally, James walked the installer through the detailed instructions ensuring he was informed and ready to go.
Communication was crucial on this project and led to a successful installation with Topline Construction and the owner highly satisfied with the finished system.

Yes, gutters protect your building, your roof, and your people from wind and rain events which can be destructive to your roof, your property, and immediately impactful to your staff. The American National Standards Institute (ANSI) recently approved the new ANSI SPRI GT-1 test standard for commercial gutters, which assists designers in ensuring gutters are tested to meet uplift requirements consistent with perimeter pressures witnessed in wind events. Metal-Era’s new gutter calculator can be found HERE
However, water control is also a future state investment, not simply for your facility, but as a socially responsible commitment.
As the climate has warmed for whatever reason you believe it has done so, and the world population continues on its path towards a projected 9.3 billion people by 2050, our total world resource for drinkable freshwater is not projected to increase substantially. Newsweek, in their cover story from 2010, quoted T Boone Pickens as saying, “Water is the new oil” given the supply and demand side threats faced to meet humans needs.
The Food and Agriculture Organization of the United Nations (FAO) which tracks long-term and short-term trending in food and water consumption, provided some dreary estimates that may reiterate our personal and professional social obligation to at least understand where our water goes. Water usage has been growing at more than twice the rate of population increase in the last century. In addition, the FAO estimates that by 2025, 1.8 billion people will be living in countries or regions with absolute water scarcity, and two-thirds of the world population could be under water-stressed conditions. Aquifers account for the majority of our drinking water, and they are often in desperate need of recharging, especially in areas affected by drought. Many countries have taken steps to artificially recharge aquifers with treated water, and have been finding success in doing so. With continued conversion of wetlands to paving and buildings, it becomes more important than ever to control and reuse water run-off through treatment and reuse. In addition, preventing contamination of run-off via fuel and oils will become more common place in the future.
How impactful is water control on a 100,000 square foot facility?A 1” rainfall will produce 60,000 gallons of water run-off on a commercial building that is 100,000 square feet.Since the average human should drink a little under a gallon of water per day for optimal health, returning the entire 1” rainfall to an aquifer could provide enough water to properly hydrate 164 people for 365 days. The less it is contaminated, the easier in the future it will be for treatment systems to return and recharge our natural aquifers.

“Resilience is the ability to prepare for and adapt to changing conditions and to withstand and recover rapidly from deliberate attacks, accidents, or naturally occurring threats or incidents.” —White House Presidential Policy Directive on Critical Infrastructure Security and Resilience
In August 2005, Hurricane Katrina made landfall in the Gulf Coast as a category 3 storm. Insured losses topped $41 billion, the costliest U.S. catastrophe in the history of the industry. Studies following the storm indicated that lax enforcement of building codes had significantly increased the number and severity of claims and structural losses. Researchers at Louisiana State University, Baton Rouge, found that if stronger building codes had been in place, wind damages from Hurricane Katrina would have been reduced by a staggering 80 percent. With one storm, resiliency went from a post-event adjective to a global movement calling for better preparation, response and recovery—not if but when the next major disaster strikes.
Improvements to infrastructure resiliency, whether they are called risk-management strategies, extreme-weather preparedness or climate-change adaptation, can help a region bounce back quickly from the next storm at considerably less cost. Two years ago, leading groups in America’s design and construction industry issued an Industry Statement on Resiliency
, which stated: “We recognize that natural and manmade hazards pose an increasing threat to the safety of the public and the vitality of our nation. Aging infrastructure and disasters result in unacceptable losses of life and property, straining our nation’s ability to respond in a timely and efficient manner. We further recognize that contemporary planning, building materials, and design, construction and operational techniques can make our communities more resilient to these threats.”
Resiliency begins with ensuring that buildings are constructed and renovated in accordance with modern building codes and designed to evolve with change in the built and natural environment. In addition to protecting the lives of occupants, buildings that are designed for resilience can rapidly recover from a disruptive event, allowing continuity of operations that can literally save lives.
Many of today’s sustainable roofing standards were developed in response to severe weather events. Wind-design standards across the U.S. were bolstered after Hurricane Andrew in 1992 with minimum design wind speeds rising by 30-plus mph. Coastal jurisdictions, such as Miami-Dade County, went even further with the development of wind-borne debris standards and enhanced uplift design testing. Severe heat waves and brown-outs, such as the Chicago Heat Wave of 1995, prompted that city to require cool roofs on the city’s buildings.
Hurricane Sandy fostered innovation by demonstrating that when buildings are isolated from the supply of fresh water and electricity, roofs could serve an important role in keeping building occupants safe and secure. Locating power and water sources on rooftops would have maintained emergency lighting and water supplies when storm surges threatened systems located in basement utility areas. Thermally efficient roofs could have helped keep buildings more habitable until heating and cooling plants were put back into service. In response to these changes, there are many opportunities for industry growth and adaptation. Roof designs must continue to evolve to accommodate the increasing presence of solar panels, small wind turbines and electrical equipment moved from basements, in addition to increasing snow and water loads on top of buildings. Potential energy disruptions demand greater insulation and window performance to create a habitable interior environment in the critical early hours and days after a climate event. Roofing product manufacturers will work more closely with the contractor community to ensure that roofing installation practices maximize product performance and that products are tested appropriately for in-situ behavior.
Research on roofing materials is ongoing to find systems rigorous enough to withstand hail, UV radiation, temperature fluctuations and wind uplift. New techniques to improve roof installation quality and performance will require more training for roofing contractors and more engagement by manufacturers on the installation of their products to optimize value. Confronted with growing exposure to disruptive events, the building industry is working cooperatively to meet the challenge of designing solutions that provide superior performance in changing circumstances to reduce long-term costs and limit disruptions. Achieving such integration requires active collaboration among building team members to improve the design process and incorporate new materials and technologies, resulting in high-performing structures that are durable, cost- and resource-efficient, and resilient so when the next disruptive event hits, our buildings and occupants will be ready. [Excerpts from Business Sense in Roofing Magazine by Jared Blum]

Regardless of which side of the aisle you are on, it's very common knowledge in the United States that politicians have difficulty agreeing on anything when there is a split public opinion.
One thing both Republicans and Democrats have agreed on, is that it’s in the public’s best interest to continue to develop construction standards which protect more lives in high wind events. In 2004, President Bush signed Public Law 108-360, titled "The National Windstorm Impact Reduction Act" with the stated intent to “reduce the risk wind hazards propose to life and property.” The law specifically directed several of the organizations it funded to recommend improvements and enhancements of “standards and technologies that will enable cost-effective, state-of-the-art windstorm resistant provisions to be adopted as part of state and local building codes."
President Obama followed this up by renewing the law, signing bill 114-52 in September of 2015, reauthorizing the National Windstorm Reduction Act.
In the 2015 document, Congress found the following: "(1) Hurricanes, tropical storms, tornadoes, and thunderstorms can cause significant loss of life, injury, destruction of property, and social and economic destruction. All states and regions are vulnerable to these hazards."
Funding for additional research was created and renewed in both of these bills. There have been many significant research projects completed by well respected organizations like NIST and NOAA to understand the effects of high winds, and more importantly, how to prevent future wind damage. The bills encouraged collaboration and pushed for additional cooperation between governmental agencies.
According to NOAA, there were over 14,000 high wind events in the United States in 2015 where wind speeds above 40 mph and/or sustaining gusts of 58 mph or higher were recorded. While the number is staggering and quite high, until a high speed wind event has affected you or your loved ones, it is very common to underestimate the potential damage this invisible natural disaster can bring. Often thought of as only being found in hurricanes and tornadoes, wind damage is a forgotten intruder.
Between 2004 and 2015, using data collected from the National Weather Service compiled by Weather DB, high winds and thunderstorm winds ranked number 8 and 9 respectively as the US most deadly natural disasters. They have claimed an average of 52 lives and injured more than 327 people annually, and accounted for over $1.18 billion in property damage. http://fox6now.com/2016/04/11/ranked-the-18-deadliest-weather-hazards-in-the-u-s/

Hazardous weather causes billions of dollars in property damage and hundreds of fatalities in the U.S. every year. The most devastating combination of similar events are wind related, such as coastal storms, hurricanes and tornadoes, which rank 12th, 3rd and 2nd respectively on the list of major U.S. disasters annually. According to The National Climate Assessment and NOAA, high wind events in the U.S. occur roughly 14,000 times annually with wind speeds of 58 mph or above. The analysis of the current data available suggests that as time goes on they will only continue to become more common.
Any type of windstorm can cause property damage, but the places hit the hardest are often those which are not accustomed to these types of extreme weather. Most industrial building structures can withstand high winds, yet the roofing system is where the damage typically occurs. Your roof edge is the first line of defense against a major wind event. For this reason, it is important to ensure that you have a rigorously tested and code compliant roof edge that is properly installed. If your roof edge is compromised, the building itself and everything inside are likely susceptible to wind and water damage.
If you look at the two pictures below you will see that once the roof was compromised, large portions of the entire building collapsed.
In 2011, an EF-5 Tornado hit Joplin, MO, with wind speeds exceeding 200 mph causing 161 fatalities and roughly 3 billion dollars in damage to 553 businesses. The Home Depot in Joplin (pictured below) was completely destroyed. Of the 73 concrete slab panels (weighing roughly 100,000lbs each) that made up the exterior of the building, 63 fell. The roof was completely torn off the building in a matter of moments. Once the roof was torn off, the concrete panels lost their stability and fell resulting in several fatalities. The building was constructed to comply with local building codes which required it to resist winds up to 70 mph. The winds that destroyed it were estimated to be approximately 165 mph.
Metal-Era’s Anchor-Tite products are rigorously tested to comply or exceed building code and FM approval for maximum wind uplift protection. Through our SPEQ promise we provide consistent wind protection, including the highest wind warranty in the industry covering the lifetime of the roof edge and winds up to 215 mph.

A proper metal roof edge, including fascias, coping, drip edge, and miters, protects the roof from wind uplift and rain intrusion. While International Building Code in all states require that fascia and coping is tested to meet the ANSI SPRI ES-1 standard, it’s equally important that these systems are installed properly. According to Factory Mutual Insurance Co. (FM) in a review of losses following a major wind event, approximately 60% of roof failures are due to the perimeter edge metal. Often times it’s because they weren’t installed correctly.
Below is a photo of a properly installed and tested metal roof edge system that remained intact after an F3 tornado struck a food storage facility in Pearl, MS. F3 tornados are estimated between 136 and 165 mph on the Fujita scale. As you can see in the foreground of the photo, the system cover and cleat held in place, and protected the roof from what could have been major damage (notice the destroyed warehouse in the background, missing walls and roof on the directly adjacent building).
There are several things to consider when installing your roof edge. Here are some pointers to help you avoid failure in low-slope roofs.
- The first line of defense is to use a roof edge that is tested and up to code standards. The International Building Code (IBC) governs that the roof edge should be designed in accordance with ANSI/SPRI/ES-1 (for more on these standards, view our webinars on www.metalera.com/continuingeducation.) Hole location, fastener type, and building type and location are some of the many factors that are considered when verifying roof perimeter securement meets code.
- The metal gauge of cleat and cover can be critical factors in successful installations, both aesthetically and structurally in a wind event. Oil canning can be a pre indicator of failure, giving you a visual indication that the width of the product may exceed normal design standards. As you can see from the image below, this metal is severely oil canned, and could be an indication of improper metal thickness.
- Overlapping of cleats, or the use of spacers (see image below) in between extruded cleats can minimize the damage from thermal movement.
- As simple as it sounds, pre punched and slotted fastener holes. Thermal movement will likely occur, and if your edge system has been designed to accommodate this thermal movement, the risk of damage to your edge metal will be significantly reduced.
- Using the correct fasteners is often overlooked by installers and can lead to the pullout of the roof edge. It’s not recommended to use roofing nails with certain systems, as they don’t have the pullout resistance that’s required for many of the systems in use today. While the use of a nail gun can be a faster installation method, it may not provide you the uplift resistance you desire. Utilizing a screw or fastener that has been tested with the assembly is a much safer solution.
- Welded or quicklocked miter systems provide a more durable wind resistant solution for inside and outside miter corners, transitions, and details. Often site fabricated details will lack engineering design for the wind uplift, offering little protection at the most vital component and area of the roof termination. In this image, a site fabricated corner has released and is no longer securing the membrane as designed.
So having a tested product with a leading warranty is a great start, but remembering the above tips when specifying and installing the roof edge metal is critical.

Quite often when specifying a metal roof edge product this question comes up. The specifier or contractor has to make a decision on whether to use a local sheet metal shop to fabricate the material or to purchase a pre-manufactured system from a company like Metal-Era.
Some of the reasons that shop-fabricated products are chosen are because they are perceived to have a lower cost and faster lead times. However, pre-manufactured systems can save a significant amount of labor time during installation. They also typically have a higher value because they’ve been tested and have a manufacturer’s warranty where shop-fabricated materials do not.
While most shops can produce a roof edge within a couple days of measurement, many manufacturers are now offering express or quick-to-ship systems that can be delivered in a week or two. The other thing to think about is a pre-manufactured roof edge can account for more variances in field conditions so the measurements can occur sooner than those that are shop-fabricated. So when you consider all of these factors, the installed pre-manufactured system can often be less expensive and arrive to the jobsite faster than the installed shop-fabricated product.
Most people think of the metal roof edge as simply an aesthetic way to finish off the building’s roof. But there is more to it than that. A properly installed roof edge actually holds the roof in place. In recent studies after major wind events, Factory Mutual Global (FM) and others have found that 60% of roof failures are due to the roof edge being inadequate. So when considering a roof edge during specification, a pre-manufactured system that will hold the roof membrane in place, as well as look good, can be key to the performance of the roof.
Most pre-manufactured roof systems, like those from Metal-Era, are tested per ANSI/SPRI ES-1 criteria to ensure that they can hold up to the calculated winds on the project where they are used. Also, many of these systems are FM approved to meet liability needs, as well as to further assure the specifier of the highest performance.
Along with their high performance and quality, pre-manufactured metal roof edges are consistent in design no matter where they are installed. Usually shop-fabricated systems will vary by contractor or location and quality isn’t guaranteed. Most pre-manufactured systems have no exposed fasteners, they have pre-fabricated and pre-finished miters, end caps and accessories, and they are able to produce radius sections to fit the project perfectly … all of which make for a clean, professional appearance.
So the answer to this ever present question is to weigh your options carefully and don’t jump the gun by specifying shop-fabricated materials without consideration of the facts. Pre-manufactured metal roof edge systems from a company like Metal-Era could save you in the short and long run.

You know what they say ... All work and no play makes for a dull boy. So we decided to liven things up on Friday, July 10 with a lunch-time Luau (Wisconsin style). It featured a "celebrity" chef, Brad Van Dam, V.P. of Sales & Marketing who donned his apron and hat to grill up some Hawaiian fare, and a guest appearance by Tony Mallinger, President of Metal-Era. The delicious menu included pulled pork, hamburgers, chicken, grilled pineapple and various sides.
No summer get together would be complete without party games to boost that competitive spirit. In Green Bay Packer fashion some of the guys threw the football around showing off their manly arms. Others partook in a "friendly" game of bags (or cornhole for non-Wisconsinites) with outstanding throwing accuracy. We do it right at Metal-Era or we don't do it at all!
Summer in July in our state means warm, humid days and that was the case on Friday. But not to worry -- We had our kiddie pools filled with ice cold water to dip our toes in, and were able to cool off by running through the Giraffe sprinkler.
The steering committee organized a great team-building event and fun was had by all. We capped the day off with a group photo sporting our Metal-Era Hawaiian shirts to mark this memorable occasion.

In past blogs we have talked about how important it is for a building to have proper intake and exhaust airflow. View a log of all 16 airflow blogs that go into detail on how ventilation can save on heating and cooling costs, eliminate ice dams, and how one size does not fit all buildings. Metal-Era has worked on thousands of airflow projects across the country, some of which can be viewed in our Project Gallery. One particular project that stands out is Metal-Era’s work on Maywood Elementary School in Hammond, IN.
Maywood Elementary School decided to reroof four of their five buildings. In the process of reroofing, they found that the buildings had no ventilation under the shingles which can easily lead to major problems like ice damming, increased cooling costs, moisture buildup and early shingle failure. The architect on the project recognized the need to create a cool roof system and recommended installing a vented nailbase.
However, the eave is only half of the problem. For a balanced roof system, air needs to come in at the eave and exhaust at the ridge. Maywood Elementary had a very complex design that made it near impossible to install a ridge vent. To help with the complexity of the airflow for these particular buildings, Metal-Era was contacted. Using our free Net Free Area calculator, Metal-Era’s technical department calculated that 24 in²/lf of Net Free Area (NFA) was needed. After this was calculated, an order was placed for 1,848 lineal feet of Hi-Perf Vented Fascia in the specified NFA.
The next step was determining what to do about the hipped roofs on the buildings which prevented traditional ridge vents from being installed. The eave to rake ratio on hipped roofs is almost nonexistent so Metal-Era explored other options. The solutions that Metal-Era created for this particular project were very custom and normally there are many challenges with hipped roof ventilation. However, in this case, Metal-Era designed custom Peak Vents specifically for this project. For other parts of the roof system, including gables, 96 lineal feet of Metal-Era’s Hi-Perf Ridge Vent Slope to Slope, Shingled Version was ordered.

After a short learning curve, the contractors were able to successfully install both the eave vent and the ridge vents. The roof ventilation system started working immediately after installation and in the hot summer sun, a heat shimmer could be seen all around the ridge vent as hot air exited the roof system.
