What is Roll Roofing?
Roll roofing is the most cost-effective solution for a new roof construction project. It allows roof constructors to fabricate a completely custom roof system that is both fastened to the existing roof and flexible enough to adapt to changes in roof angle and slope. The system meets all design specifications and can be manufactured to fit any square footage of roof area. This provides numerous advantages over traditional shingle applications and is favored by several building code jurisdictions in the U.S.
Roll roofing, sometimes also known as membrane or asphalt roll roofing, is a pre-manufactured roofing product typically used for buildings which have a low-pitched roof pitch. The material used is typically based on the same compounds used in fiberglass shingles; a light synthetic felt or rough fiberglass matrix, sprayed with asphalt and topped with a granular top coating. The synthetic material provides the feel of a thicker roofing membrane at the same weight and cost. When the membrane is applied correctly, the felt instantly begins to conform to the pitch of the roof, providing added strength and reliability to the roof system. Once the felt has sufficiently adapted, the roof system will no longer require repair or maintenance.
There are three types of rolls available from which to choose: flat roofs, jointed rolls, and seamless rolls. Flat roofs consist of horizontal seams between two pieces of textured or flat roofs. These seams provide additional strength and stability to the flat roof. Gaps between seams are closed using either mesh or perforated metal. Seamless rolls do not have seams and allow for easier removal of debris and clogs easier than rolled roofing materials.
When it comes to what is roll roofing, the most affordable and easiest type is flat roofing projects. However, they are also the most costly because there is a greater degree of labor involved in the installation. Flat roofs are less expensive to install because they do not require stucco, tar, gravel or gypsum. The surface of the roof is smoother because there is not a granule of clay soil that must be removed. If you are interested in a less expensive installation option, seamless rolled roofing materials can also be used.
The third type of what is roll roofing is shingles and asphalt. Similar to the other types, shingles are made of one or more layers of paper materials that are fused together. Each paper layer is about one inch thick. They are easy to install and because they are fused together they offer more flexibility in shape because they are per square foot less expensive than shingles.
Roll roofing materials are available in shingle and asphalt types. Both shingles and asphalt are used as a base for rubber roofing. When you are installing what is roll roofing, you will have to select the appropriate materials depending on what you are using your new roof for. All three materials are easy to install, but each one has its own benefits and drawbacks.
