Roofing contractors can determine the roof pitch using a roofing pitch gauge. The tool can be purchased from most home improvement centers or downloaded from any app store. The device measures the height of the roof surface and the length of the roof span. Multiply these numbers to obtain the total area and the plane area of the roof. Typically, roofing professionals measure a gable roof to determine the roof pitch. In addition to measuring the pitch, roofers also take the pitch of an existing roof into account when planning a new roof.
Roofing felt is an additional barrier against water and resin bleed, which is especially important if a fire occurs. Roofing felt also smooths the sheathing of a roof to prevent unevenness in the final layer of shingles. Several different types of shingles can be used on a single roof. While random-tab shingles are durable, they are not very beautiful. Nevertheless, they are an attractive option for a variety of reasons.
Random-tab shingles have small tabs that vary in size and exposure. Depending on the type of roof covering, you can choose one or two types of shingles for your home. To install a new shingle on the existing roof, use release tape to prevent the shingles from sticking to each other. A release tape is a simple adhesive that does not need to be removed. Roofing can also include a protective coating for the interior of a home.
