When you think about your roof, you probably imagine a solid, waterproof covering for your home. And while that’s true, your roof also needs venting. You’re probably thinking: why would I need vents in my roof, wouldn’t that let in water and interfere with my HVAC?
However, roof vents are actually critical to the effectiveness of your roof in protecting your home.
Roof vents are narrow, protected openings in your roof that allow ventilation and airflow. For example, the hot air that rises to your attic can only escape through vents at high points in your attic if there are lower vents that allow cold air to enter and force the air to circulate. This is why you have ridge vents along the high points and ridges of your roof as well as vents along the edges of your roof or in your gables.
Some of the most common causes of roof damage include ice and snow. Ice dams develop when hot air accumulates under your roof and melts the snow and ice. However, as the melt runs down your roof toward your gutters, it refreezes. If you have too much water, and subsequently ice in your gutters, it can cause a wide range of problems to your roof, siding, and overall comfort. If you have proper ventilation, the hot air can escape your roof before it creates a hot spot and melts the snow.
Even in the summer, if hot air can’t escape your attic, the heat builds up and can eventually damage your shingles from the inside.
Do you steam up the mirror in your bathroom when you shower? The moisture builds up as the moist warm air contacts the cool mirror in a process called condensation. This can also happen in your attic if the hot air doesn’t escape through venting. The heated air eventually cools along the walls, and if there’s any moisture in the air, it will condense on your walls and lead to mold and other damage.
A well-ventilated roof can also increase the effectiveness of your HVAC system. When the hot air rises and accumulates in your home, your air conditioner has to work harder to cool your home. Roof vents allow warm air to escape, which reduces the burden on your HVAC and your wallet.
If you feel like there’s a 10-degree difference between your upstairs and downstairs or if your feet are always freezing even if the room doesn’t feel cool, chances are that your roof isn’t properly ventilated. Roof venting allows air to circulate as well as letting hot air escape. This helps regulate the temperature of your home so that you’re comfortable year-round.
In addition to the interior signs of inadequate roof ventilation, you may also be able to see clues from the outside. For example, you may notice:
