The build-up of snow and ice at the eave can lead to structural damage, water infiltration and a number of other costly issues. Annually, millions of dollars worth of insurance claims are filed for damages related to ice dams. Depending on the policy and carrier, these claims can be difficult to collect.

Those areas with an average temperature for January of 30° F or less are primarily at risk for ice dams, however, it is not uncommon for states farther south to experience ice damming. To reduce your risk of ice dams, make sure that you have proper ventilation at the eave and ridge of your roof.

Improper ventilation often results in excessive moisture accumulation. That moisture build-up can lead to unhealthy and unsightly mold and mildew in as short as 24 hours.

Mold removal is frequently costly; both in terms of the actual expense, and also in lost work time and potential litigation. In 2002, about $3 billion in mold claims were paid out according to the Insurance Information Institute. Proper roof ventilation and airflow are keys to preventing the moisture accumulation that leads to mold.

Without a cool roof, shingles will often bake and temperatures can reach as high as 150°F significantly shortening their lifespan. Visible signs of shingle failure due to insufficient ventilation are peeling, cupping, blistering and general deterioration.

So be sure to specify a commercial-grade ventilation product that can provide the correct amount of net free area (NFA) for your building and create a cool roof. Remember that a commercial building has larger NFA requirements that most residential products don’t satisfy.

In warmer weather, heat builds up in the attic and gradually radiates downward throughout the entire building. This places increased demands on your air conditioning unit. To help reduce heat build-up in your attic or along the ceiling and decrease your HVAC costs, maintain a consistent roof temperature through proper ventilation.

Cool Roof / Balanced System

A cool roof reduces your risk of premature shingle failure, water infiltration and the multiple issues that ice dams create. Additionally, your cooling costs will go down.

Commercial buildings usually have longer runs, larger roof surface areas, lower pitches and larger heating and cooling systems. All of these factors make achieving the correct net free area (NFA) more challenging with residential product offerings. Using a larger air space and a balanced system (equal amounts of intake as exhaust) will increase your NFA to the correct amount for your project.

Metal-Era’s Airflow Solutions are designed to meet commercial NFA requirements. Let us help you find the right system for your next project.

Hi-Perf Intake Vent

Hi-Perf Intake Vent is the perfect ventilation solution for roofs without eaves. It is also frequently used when venting from a flat roof to a steep sloped roof.

This highly versatile system is custom engineered to meet the exact net free area (NFA) requirements of your building. It includes the industry’s only Airflow & Wind Warranty, which ensures long-term, worry-free performance.

Hi-Perf Ridge Vent - Slope to Slope Version

Hi-Perf Ridge Vent: Slope to Slope Version is engineered specifically to each project’s net free area (NFA) requirements, providing optimal exhaust ventilation.

Backed by the industry’s only Airflow & Wind Warranty, you are assured long-term, worry-free performance. The snap-on cover with prepunched holes allow for quick and easy installation. It is available in both shingled and standing seam versions.

Hi-Perf Ridge Vent - Slope to Flat Roof Version

When venting a mansard roof or one with multiple roof levels, Hi-Perf Ridge Vent: Slope to Flat Wall Version is an ideal choice. Our expert technical department will help you determine the correct amount of net free area (NFA) for your project. Like all Hi-Perf Systems, the Slope to Flat Wall Version includes the industry’s only Airflow & Wind Warranty.

Hi-Perf Ridge Vent - Slope to Vertical Wall Version

When faced with a sloped roof that meets a parapet wall ventilation is often a challenge. That is why Metal-Era designed the Hi-Perf Ridge Vent: Slope to Vertical Wall Version.

This ridge vent allows for optimal exhaust ventilation by providing custom-calculated net free area (NFA). Its 12’ lengths, prepunched holes and snap-on cover will speed your installation. It also includes the industry’s only Airflow & Wind Warranty.

Hi-Perf Ridge Vent - Slope to High Wall Version

Intersecting roofs with multiple roof levels are often very architecturally interesting and beautiful, yet they are often difficult to properly ventilate.

Hi-Perf Ridge Vent: Slope to High Wall is designed to meet your net free area (NFA) requirements when venting a sloped roof that meets a high wall. This system includes the industry’s only Airflow & Wind Warranty, just like Metal-Era’s other Hi-Perf systems.
