Asphalt shingle Roofing in Bellevue WA is the most prevalent choice for residential customers of local contractors. Many homeowners don’t realize that the material is referred to as an asphalt shingle until they begin looking for a contractor to do roof replacement. They know what roof shingles are, of course, and are familiar with the rough texture on top. What is the actual relationship between asphalt and these roofing components?
Composition of the Shingles
This type of Roofing in Bellevue WA actually is made of asphalt, a similar material to that commonly used for pavement. The shingles contain other substances as well. They only contain about 30 percent asphalt on average. During manufacturing, felt paper or fiberglass is coated with asphalt and then has granules made of ceramic adhered to the top. For this reason, the components are also known as composite shingles.
Those little granules are applied liberally during the manufacturing process, so it’s normal to see some of them have come off even when the roof is fairly new. They can appear in the bottom of downspouts after a heavy rain, for example.
Types of Shingles
The most economical choice is called the three-tab shingle. Each component conveys the illusion of being three shingles when actually it is only one. Other types of these shingles are available too, however. Some have added depth that homeowners find especially attractive. Asphalt shingles in general are less expensive to have installed by a contractor such as North Creek Roofing because the project is easier than the installation of metal or other materials.
Although some men and women like the aspect of metal roofing being fire resistant, asphalt shingles hold their own in this regard too. They are significantly better in this characteristic than wood shakes or shingles are. In fact, some home insurance companies charge higher premiums when the roof is made of wood. There is little prevention against fire if lightning were to strike the building.
Interestingly, recycled asphalt shingles are increasingly used as a component of blacktop pavement. That is making them a more environmentally option than was true in years past.
