One important part of shingle choice is the fire rating, which indicates how fire retardant the shingles are. Fiberglass asphalt shingles have the highest rating available. Fiberglass shingles are composed of a fiberglass mat sandwiched between layers of asphalt and mineral granules. The most basic style of asphalt shingle is called the 3-tab shingle. Because it offers no texture, such as the mineral granules on fiberglass shingles, they are the least expensive asphalt option. However, because the look of a 3-tab shingle has become somewhat dated, most homeowners prefer a different option. Organic shingles are another common type of asphalt shingle. Instead of using a fiberglass mat, organic shingles use an organic felt material that has been saturated with asphalt to make it waterproof. They are then topped with adhesive asphalt and covered with mineral granules. Talk to an expert in roofing in Vancouver to figure out which option is best for your home.
