When learning how to install roll roofing, keep in mind that it may not be completely flat. You must cut the sheet into 12 to 18-foot strips and overlap them by about three inches. Generally, cold weather can make roll roofing too brittle to handle. During this time, it may be best to start laying the roofing sheets in the garage to warm them up before attempting them outside. Afterward, you should apply a sealant to the top and sides of the roof and trim the sheets with a utility knife.
Before installing roll roofing, you should measure the area of the roof. If it is in bad condition, you will have to calculate the surface area of each roll. Next, you should add the total area to find the proper amount of material to buy. If the roof is in good shape, you can simply add the total areas. To avoid damaging the existing paneling and fascia, you should use a measuring tape to make sure that you are calculating the correct amount of material to purchase.
To install roll roofing on a roof, you should first mark the bottom of the roof with a chalk line. This line will be the starting point of the first layer of the material. Once you have marked this line, you can begin installing the second layer of roll roofing. The first layer should overhang the drip edge by a quarter-inch. Using a trowel, you can apply roofing cement along the edges of the first layer. Repeat this process until the entire roof has been completed.
Before you start installing the roll roofing on your roof, you must measure the width and length of your roof. A square or rectangular roof is easier to measure than a curved one, but whatever shape your roof is, you should know how to do it. Then, measure the height and width of your roof. Multiply the two measurements together to find the correct length. Lastly, nail the felt to the roof. In a few minutes, you should have a perfectly functioning roll roofing.
The next step is to prepare the roofing area. To install roll roofing on a roof, you should clean the surface of debris. It is recommended to use a sprayer for the primer. You should also make sure the temperature is between 45 and 50 degrees, as the primer may cause your roof to buckle or wrinkle. Once the roof is prepared, you should apply the roll roofing. You should also check the regulations of your HOA before you install roll roofing on your home.
After applying the sealant, you should lay the roll roofing sheets flat and aligned. To make the roofing sheets flat, you should place bricks in the corners. In order to reduce the amount of resistance, lay the sheets on the roof in a garage. After the adhesive has set, you can now attach the rest of the row with nails. The base sheet should overhang the drip edges by 1/4 inch. Aside from nailing the roll roofing, you should also apply the adhesive in the roof to ensure a strong foundation for the shingles.
