As you plan out your roof replacement project, you might consider several kinds of roofing materials, including asphalt shingles. Of the roofing materials offered on the market, asphalt shingles stand out as the most popular choice for many homeowners.But not many homeowners are familiar with the roof construction process, and their knowledge is limited to the visible top roof layer, that is, shingles. McGuire Roofing & Construction, your trusted local roofing contractors, shares the six key components of an asphalt shingle roofing system. 1. Asphalt Shingles They are the most noticeable part of the roof and the one that takes the full impact of weather damage. Asphalt shingles typically come with a fiberglass base and are coated with protective mineral granules to head off windstorms, heavy rainfall, and blistering heat. 2. Underlayment This offers an extra layer of protection between the wood deck and shingles, helping protect the system from water infiltration. Roof repair providers will also tell you that the underlayment also supports your home’s stability and ensures that roof leaks and debris won’t enter your home. The underlayment may come in asphalt-saturated, organic and rubberized asphalt options. 3. Starter Strips These refer to the first row of material that helps stop shingles from blowing off during high winds. Not only do starter strip shingles prevent water infiltration, they are also critical for proper roof installation. 4. Ice and Water Barriers During the winter season, these barriers play a vital part by protecting areas on your roof that are vulnerable to water penetration including the area around chimneys, dormers, valleys, skylights and vent pipes. 5. Hip and Ridge Products Also known as ridge cap shingles, these components add to your roof’s character by enhancing your roof’s design while increasing its functionality. 6. Ventilation System Installing a quality ventilation system for your home allows your roof to breathe and expel any excess air and moisture that may enter your roof, preventing early deterioration as a result.
