There are several different roof materials and roof systems, and each one has its own installation process. The first step for each one is safety. Your roofing professional should wear the appropriate safety gear, perform the work when the roof is dry, and follow manufacturers instructions.
A layer of starter shingles begins the installation process for asphalt shingles. Starter shingles are nailed about half an inch past the drip guard. They don’t have the same seams that asphalt shingles do, which helps keep water off the underlayment. Starter shingles should also be applied by eaves and joints. Then, it’s time to install the first course of shingles. This should be done by starting at the bottom of your roof and overlapping the shingles, working across.
A chalk line can be used to help keep the shingles straight. The shingles should lay so that the top layer of shingles covers the seams of the bottom layer. There should be at least 4 roofing nails per sheet and the nails need to be hammered straight down.
It goes without saying that roof replacement costs and roof installation costs vary by the type of roof material you want, the square footage of your roof, and how complicated your roof is. On average, most roof contractors will charge between $350 and $600 per 100 square feet for an asphalt shingle roof. On average, the cost to install a 2,200 square foot roof can vary between $7,000 and $13,200.
