Fiberglass asphalt roofing shingles are now the most common roofing product for residential construction. They replace organic asphalt shingles – a mainstay of roofing for many years. The fiberglass is added to the base felt of the roofing to help reinforce it and provide additional strength that had been lost in the switch from the original organic products. Fiberglass roofing comes in numerous styles, colors and weights making them suitable for almost any residential roofing application.

Considerations
While the fiberglass reinforcement added to the base felts holding the granular wear surface of the roofing shingles is intended to help strengthen them, this composite product has not been without some problems. According to the HouseMaster Technical Staff, inherent properties of the manufacturing process and materials have made some roofing susceptible to premature failure. Consequently, a thorough evaluation of even a new roof is important to insure the adequacy of its condition and function.
