Flat roof repair – Important steps
Removing the damaged area and replacing it with a new section would be ideal for small damaged areas of the roof. Dirt and gravel from the damaged section of the roof should be cleaned by grabbing a broom and sweeping it clean. The gravel should not be discarded and can be used for repairs. The damaged area can be removed by using a straight edged utility knife. You will need to put some effort for cutting a rectangular section of the roofing material. The first layer of material needs to be cut first and the other layers that are damaged can be cut after this and this is one of the important steps of restoring the roof.
From an asphalt shingle or roll roofing, you can cut out a replacement section of roofing material. Depending on the size of the section you removed for repair, the replacement piece should approximately be of the same size. Inside the cutout area, you can spread some plastic roofing repair cement and you must ensure that the cement is over the edges of the cutout section. Nail the patch after setting it properly in place. The patch should be placed around the perimeter of the section and you can use galvanized roofing repair nails that are spaced approximately 2 inches apart for the purpose of repair.
A replacement that is 4 inches larger than the first replacement needs to be cut and the first patch must be overlapped by this by at least 2 inches on each side. Roofing cement can be used to cover the first replacement patch and you must extend it by at least 3 inches outside the patch perimeter. Similar to what you did with the first replacement you would need to press down the second replacement and hold it in place as you cement and nail it.
Flat roof repair made easy
Sweep back the gravel onto the top of the patch to help hold it in place after the cement has begun to set in. If the cement has not hardened the wind could easily pick the patch job and blow it away and you would have to start the repairs all over again.
Try to locate leaks by examining the lower lying areas of the flat roof as this is the area where most often the damage occurs due to water pooling there. Soak water by using absorbent materials and cloths. Look for blisters or a crack in the roof after the area is completely dry. Use a knife to open the blister that you had located. Ensure that the knife does not go deep as it will cause more damage. Wait for the area to dry after draining the water from inside the blister. Seal it tightly after applying some roof cement to the flat roof repair.
