Proper ventilation is critical to prevent damage to your roof and other parts of your home. If you’ve experienced roof damage, ice dams, moisture buildup, or high utility bills, your roof may benefit from additional ventilation.

Why Does a Roof Need Ventilation?

In the winter, heat from a poorly ventilated attic can melt snow on the roof. Water that runs down to the eaves can then refreeze and form ice dams, which can damage the roof and cause leaks and other problems. Roof vents can keep the roof cool in the winter and prevent ice dams from forming.

Vents in your roof can keep the attic from becoming unbearably hot in the summer. Vents can allow heat to escape, which can keep the house cooler, let you rely less on air conditioning, and keep your utility bills down. 

High temperatures can cause roofing shingles to wear out earlier than they should. Improving ventilation can reduce the risk of roof damage and increase the roof’s lifespan.

Moisture can damage roofing components and can lead to mold growth. Vents can allow warm, moist air to escape from the attic and let cool, dry air in. That can prevent moisture buildup, keep mold from growing, and protect your insulation from moisture damage.

How Much Ventilation Does Your Roof Need?

The answer to this question depends on several factors. While there are general guidelines based on the size of a roof, other variables, such as the climate, the design of the house, and whether the roof has a vapor barrier, will also come into play.
