Fiberglass Shingles and Roofing

Due to their unique construction and the hydrocarbons in the fiberglass itself, this shingle type actually becomes stronger in colder weather and is less likely to tear, thus why it is so commonly used in colder regions.

Unlike organic asphalt roofing shingles which are manufactured using a paper backing that is saturated in asphalt, fiberglass shingles are constructed using a fiberglass mesh backing that is coated in asphalt.

The fiberglass shingle mesh backing is constructed using random layers of fiberglass that are fused together with urea formaldehyde resin. The fiberglass backing mat is then coated with asphalt. Sand granules and algae resistant paint are then imbedded into the asphalt to complete the manufacturing process of the fiberglass shingle.

Fiberglass roofing shingles are available in a wide variety of colors and can be purchased as 3-tab shingles and architectural shingles.

Another key advantage of the fiberglass roofing shingle is that it offers a higher fire resistance rating than the organic asphalt shingle, due mainly to the fact that there is less asphalt used in the construction of it. In addition, for the same reason, the fiberglass roofing shingle is also much lighter than the organic asphalt shingle. The lighter weight makes it easier to install fiberglass shingles.

Fiberglass shingles are also very economical compared to most other types of roofing materials. Likewise they are very easy to install compared to other roofing solutions.

Fiberglass shingle warranties vary from around 20 to 40 years, but on average you can expect to buy fiberglass shingles that will last you around 30 years if they are properly installed and the attic below them is properly insulated and ventilated.

The insulation and ventilation help protect the asphalt shingles from intense heat during the warm weather seasons. If fiberglass shingles are exposed to intense heat their lifespan can be dramatically shorten. Signs of failing fiberglass asphalt shingles shows up as curling edges, or split and cracked surfaces. So if your home’s existing roof shingles are cupped, cracked, splitting, or curling, or you’re building a new home or home addition, consider installing fiberglass shingles.

Though relatively easy to install, I would still recommend having a professional roofing contractor install them.

If you do elect to install the shingles yourself, make sure to first carefully read the fiberglass shingle manufacturer’s installation instructions. Proper nailing and cutting is critical for ensuring a properly installed roof.
