If you are installing roll roofing on a flat roof, the first step is to measure the roof. You may want to hire a friend or a professional to assist you. For a square or rectangular roof, measuring the roof will be easier. To determine the width and length of the roof, measure it first and multiply them to find the appropriate number of rolls. Once you have the right number, cut the rolls according to the measurements.
After you have the right size of roofing rolls, make sure to smooth them before securing them. You may also want to use roofing cement to help secure the roll roofing. Using roofing cement will make sure the roof has a smooth surface and that there are no rough edges. After you have installed the roofing, you will need to seal the edges using roofing cement.

Before installing the first layer, you should mark the edge of the roof with a chalk line. Next, you should cut the roll roofing so that it spans the valley and ends about 1/2 inch below the center of the valley. Then, you should install the second layer of roll roofing, measuring 32 inches above the first. As you continue with the roofing, don’t forget to use roofing cement to seal the edges.
Before installing roll roofing on your flat roof, you should prepare the roof surface by keeping it clean and dry. In cold weather, roll roofing is prone to breaking and can be very difficult to manipulate. To avoid breaking rolls, cut the sheets into 12 to 18-foot-long pieces and place them inside your garage. The sheets can take several days to flatten properly, but this shouldn’t be a problem during warm weather.
