The Northeast is a unique climate in that it goes through four seasons of extreme temperature variations, from hot and humid in summer to cold and snowy in winter. To withstand all those elements, your roof has to be strong, #1. And #2, it needs proper ventilation. Here’s why roof ventilation in the Northeast climate is essential.

Why You Need Attic Ventilation

In short, ventilation is what allows your attic – and home – to breathe. Without it, your roof cannot protect the rest of your home properly. That’s why making sure you have a sufficient ventilation system is critical in protecting your investment. Your ventilation system works by drawing in fresh air from outside, then pushes the trapped air in your attic through the roof vents.

You may wonder: why is proper attic ventilation in the Northeast so important, and particularly in winter? While important year round, ventilation is even more imperative because the heating system is working hard to make your home comfortable. When that warm air rises into the attic and comes into contact with the cold air, this creates moisture.

If you don’t have enough vents or insulation, condensation will form on the decking, which can then rot the boards and result in structural damage. It can also grow mold and mildew. However, when you have sufficient attic ventilation, that excess moisture is able to escape while drawing in fresh air from outside.

This constant flow of air prevents dampness, helps to improve air quality ,and contributes to an overall healthy living environment your family.

Prevent Ice Dams

Proper attic ventilation also prevents the formation of ice dams on the roof after a heavy snowfall or ice storm. Ice dams form when snow or ice freezes along the eaves, resulting in a large block of ice. When that ice thaws, the water cannot drain off your roof properly and may drip into your home. The right attic ventilation will ensure your attic stays at a consistent temperature to reduce the risk of ice dams.

Energy Bills

Did you know proper attic ventilation can also keep your energy bills down? Without enough ventilation, your HVAC system has to work overtime, straining the system and increasing your energy bills. Take this as an example: let’s say the outside temp is 90°F in summer; well, your attic can reach temps of up to 170˚F. Because the trapped heat has nowhere to go, your attic floor can reach as high as 140˚F. As a result, rooms directly below it won’t get cool enough for comfort.

Roof Lifespan

With the right attic ventilation, you can maximize the lifespan of your roof. Trapped hot or cold air can reduce your roof’s lifespan, causing you to have to replace your roof prematurely. Not only will the shingles curl and crack, the decking adhesives will deteriorate. All that summer heat is literally burning up your roof. It needs a way to escape!
