There are two basic types of roofing materials: asphalt and plastic. The former is the least expensive, and requires minimal maintenance. The latter is more expensive and requires a higher level of expertise. However, the most common choice is a built-up roof, which is composed of multiple layers of ply sheets embedded in hot asphalt. Typically, three to four bundles are used per square foot. The caps are overlapping, and their role is to prevent water from flowing behind the base flashing.

Depending on the material, a roof may be made of natural or synthetic materials. The base material is made of a flexible substance known as roofing felt. A layer of bitumen is applied to the felt to repel water while allowing the product to breathe. When windy conditions cause the rain to accumulate, this can lead to leaks and rot. To avoid this problem, roofing felt is the best choice. In most cases, the roof is covered with a layer of plastic.

When reroofing a home, it is best to remove the old roof completely. To prevent the need for a new roof, the old one should be removed first. This can lead to a lot of work for you and your family. It is important to be fit before you begin, and make sure to test the ladders and shingles before you attempt the task. A good rule of thumb is to avoid tearing off the old roofing.

During reroofing, a base sheet of asphalt and a cap sheet of mineral-surfaced material is placed under the new roofing. This protects the roof from resin bleed and acts as an additional barrier in the case of a fire. It also smooths out the sheathing of the roof to prevent unevenness in the final layer of shingles. You should also make sure that the reroofing is installed properly.

Roofing felt is an essential part of the roof. This is a layer of roofing felt that protects the roof from resin bleed and acts as an additional barrier in case of fire. If you live in a humid climate, you should also consider installing a layer of roofing tar paper over the shingles. It will help prevent the final layer of shingles from being uneven. There are two types of felt: open valley and closed valley.
