DIY Roofing Instructions
DIY roofing is a do-able task for even a fairly inexperienced do-it-yourselfer. The most important thing to do before beginning this project is to research carefully. You first need to decide what kind of roofing you are going to use; the type of material you choose will determine which installation method is required. As asphalt shingles are the most common, least expensive, and easiest to install, we will look at the steps involved in roofing your home.
DIY roofing steps
There are not many steps involved in DIY roofing, but to do it right, you have to take you r time and follow instructions, both general and those instructions of your roofing material manufacturer. If your roof has less than three layers of old shingles, it is not necessary to remove the existing roofing. If you are starting from scratch, or if this is new construction, the first thing to do is to put a felt underlayment directly on top of the wood and nail it down. This should be attached left to right, bottom to top. Make sure that each layer overlaps the previous by at least two inches to prevent leakage.
After the felt has been laid, you need to nail down a starter strip of shingles. Do this by laying a chalk line down the exact middle of your roof and then placing the starter strip to the right, along the bottom edge of the roof. Next, lay another chalk line down the middle of the roof and put the first shingle directly over the middle of it. Make sure each shingle is butting up next to the other; continue working out towards the end of the roof. Then go back to the center and work out towards the other end.
When you've finished the first row, go back to the center and begin again. Each row of shingles needs to overlap the one below by two or so inches, depending on the manufacturers' instructions. Be careful to hammer in the nails straight up and down, not at an angle, which may damage the roofing.
