Can You Nail Into Your Roof?
A roofing system is specifically designed to make sure water is kept out of your home. Roofers achieve quality roofing by layering materials on top of the decking, or wooden foundation, of a roof. There are various components of a pitched roof, ranging from felt underlayment to roof shingles and flashing. Together, these force water to run off a roof into the gutters and away from the house.
If you drive even one nail into your roof, you take the risk of compromising the entire system. That one nail will put a hole in the shingles and underlayment of your roof, so when it rains, water has a place to seep into, which can eventually compromise your roof. This minute nail can cause a small leak, and even minor leaks can end up causing significant problems.
You could be asking, don’t roofers use nails when they install roofs? Yes, professional roofers do use nails, but they do it in a very specific way so each nail is covered by the shingle that is above it. Adding another nail above the shingles will compromise your roofing system.
You could have heard that attaching something under the roof shingles is a good way to avoid this issue; however, even this has to be done carefully. A shingle must lie flat against the roof in order for it to work properly. Even a nail that is under-driven, which is a nail that is not driven deep enough into a shingle, can cause a problem. As this will prop up the shingle slightly, and this is enough room for water to seep under the shingle. If your roofer does add another nail under the shingles, they will make sure that it lays flat.
