How to install rolled roofing on a shed.

While rolled roofing is cheap and easy to install its resale value is perilously low when it is used to roof occupied structures. Prepare a valley between joined roofs by cutting a strip that is 18 inches wide and covers the entire length of the valley. Step 1preparing to install rolled roofing prepare the roofing cut the roll roofing into lengths long enough to cover one run across the shed roof or of 18 whichever fits your shed better and lay them out on a flat surface to smooth them out. 2 like any other roof project you should start this one by addressing the valleys.

Rolled roofing is best installed on unoccupied structures such as sheds shops garages and other outbuildings. Attach it to the valley with roofing nails spaced 6 inches apart about 3 4 inch from the edge. If you have a sloped roof cut strips of roofing 9 inches wide position them flush with the drip edges along the eave and rake and attach them by driving two rows of nails that are about 3 inches apart. Place a sheet of 36 inch roll roofing directly over the 18 inch roofing that is covering the valley.

Nail it down exactly as you did the 18 inch roofing. Once the first row is done add approximately two inches of cement to the top of the first row to secure the second row of roofing. Use a trowel to spread roofing cement over half or more of the strips. Again trim any roofing that extends beyond the edge of the roof.

Apply about two inches worth of cement under either side to seal the roofing down and then nail it down making sure it still stays flat and even as you go.
