You can say a lot of things about roofs, and most of them might be true. But one thing that nobody can argue with is that roofs are tops. This statement can be taken in several ways. A roof does for the top of your home. It can also act like a "top" or lid for your home, keeping the rain out. Then, there's the third meaning, which is the one we happen to like the most: roofs are the best. (People say things are "tops" when they really like them.) Since we like roofs so much, we've decided to write about them, and you've discovered the blog where we do that.
You probably know the main components of a shingle roof, but you may not be aware of the role ventilation plays in helping the shingles have a long life. If your shingles are curling or have blisters, the problem might be due to a lack of ventilation. This might happen if a soffit vent is closed off by insulation or if a mechanical vent stops working. Here's a look at the purpose of roof ventilation and some roof repairs you might need to have done because the ventilation is inadequate.
Poor Roof Ventilation Ages Your Shingles
The shingles on your roof overheat without enough ventilation in your attic. This causes things like curling and other damage that shortens the life of your roof. Poor ventilation causes the underside of your roof to be too hot, even in the winter. This is the main cause of ice dams that damage your shingles.
Besides roof damage, poor ventilation can cause mold to grow in your attic. Humidity levels might rise in your attic and home and attract bugs. These problems can be solved and prevented when a roofing contractor repairs your ventilation system or installs new vents.
Roof Repairs Can Save Your Roof
Replacing bad shingles is a common residential roof repair. However, the need to replace shingles can sometimes be avoided if you make sure your attic has proper ventilation. The first step in roof repairs is to improve ventilation.
The roofing contractor might do this by clearing obstructed vents, repairing broken mechanical vents, or by installing new vents. Roof ventilation can be achieved by adding a mechanical vent, such as a turbine fan, to the top of your roof. The fan may be powered by wind or electricity, and as it spins, it pulls in cooler air and releases hot air from the attic.
Ventilation can also be achieved naturally through soffit and ridge vents that allow hot air to escape through the top of the roof while cool air is pulled in through the soffits. A roofer can add more vents when needed. They can calculate how many vents should be installed based on the square footage of your attic. Once the vents are in place, they should be checked regularly and repaired when needed.
Once adequate ventilation has been established for the attic and underside of your roof, it's time to repair any damage the hot roof may have caused. The roofer might have to replace shingles on the side of the roof that gets the most sun. A few curled shingles might be repaired instead by gluing the curled edges down so the shingles are flat.
