Roof ventilation is definitely not a sexy topic. Most people unless they are roofers or builders don’t think about roof ventilation at all. We all know that there are vents on our roof but whether we know why is the question at hand. Basically, the quick answer is that we need roof ventilation to remove hot air in the summer and moisture in the winter.
Most often on homes, there are vents on the soffits under the roof edge that bring a flow of air up through the attic and out through either roof vents or ridge vents. This is a system of ventilation that takes advantage of the natural airflow of the house. Hot air naturally rises and air then flows from the eaves up through vents at the top of the roof. There are also electric and solar-powered vents that can draw the hot air up and out of your roof.
Proper ventilation reduces wear on your shingles. Think of a poorly ventilated attic like an oven. In the summer an attic with insufficient ventilation can reach 160 degrees. Combine the heat from the inside of your attic with the sun beating down on the surface of your roof and you are pretty much baking your shingles. This can cause a breakdown on the integrity of the shingles. This can definitely lower the lifespan of your roof.
Even though attic ventilation here in Texas is not one of those things that cross our minds much, having it done properly is essential to the well being of your home. Proper ventilation not only adds to the health of your roofing system and attic but also saves on your energy bills. A comfortable home environment starts with a good roof ventilation system.
