Shingle Roofing In Phoenix
Asphalt shingle roof systems are the most commonly used roofing materials today, both in residential and multi-housing properties in the Phoenix area. Asphalt shingles are made either of composition substrate or of fiberglass. The fiberglass substrate shingles have a higher fire retar-dant rating because fiberglass is not combustible. Asphalt fiberglass shingles are available in 20-year and 25-year 3-tab (your most inexpensive), 30-year and 40-year dimensional shingles and 50-year lifetime shingles.
The shingle roof system is made up of a moisture barrier felt like an ASTM 15# or 30#, and ice or water shield around the eves, penetrations and valleys (depending on where you live) and of course your asphalt shingle.
Shingle Roof Systems For Phoenix
Advantages: Asphalt roof shingles continue looking good with little maintenance. Also, they can easily be repaired if they happen to become damaged. They are one of the easiest types of roofing material to install. A big advantage of asphalt roof shingles is their cost. They can efficiently be manufactured in high volumes, so are relatively inexpensive to produce. The installation cost of asphalt roof shingles is also relatively inexpensive compared to other materials.
Disadvantages: Asphalt shingles have a shorter functional life than other traditional materials as tiles, slates, etc. A functional life of 15-20 years for a good quality asphalt shingle seems to be logical. We have seen guarantees for 30 years or more, these are mar-keting exaggerations. Asphalt shingles usually attract large amounts of heat, which are then radiated down-wards. Big amounts of heat influence shingles in a negative way, reducing their life span. Substandard application techniques make asphalt shingles prone to wind uplift. Asphalt shingles are prone to mechanical damage when walked on particularly if temperatures are high.
