Life Expectancy of Fiberglass Shingles

Whether you’re getting your house ready to sell or you want to make an update to your forever home, it’s important to research which shingles will make the most sense for your home and your pocketbook. While fiberglass shingles may cost more per square foot than your average asphalt shingles, their quality and longevity can add significant value to your home and save you money on costly roof repairs. With proper maintenance, you can expect fiberglass shingles to last for 30-50 years. That’s a potential half-century of use that you can get out of these sturdy shingles! So why does the life expectancy of fiberglass shingles outshine many other roofing materials?

Life Expectancy of Fiberglass Shingles

The Composition of Fiberglass Shingles

One factor that contributes to the life expectancy of fiberglass shingles is their composition. They are made of a woven fiberglass mat. On top of this base is an asphalt coating that makes the shingle waterproof. To make these shingles even sturdier, manufacturers add a third layer of ceramic granule, which protects your roof from damaging UV rays.

But it’s the fiberglass mat that truly sets these shingles apart. The base requires less asphalt to provide the shingles with superior strength, meaning these shingles are stronger yet more lightweight than traditional asphalt shingles. Fiberglass shingles also work well in various climates. And these resilient shingles are non-porous, which means they are less likely to change shape from heavy precipitation, and they won’t dry out during a drought.

The Importance of Roof Maintenance

Even though fiberglass shingles are sturdy, they’re susceptible to wear and tear just like any other roofing material. To make sure you get the most use out of your shingles (and to protect your warranty), be a responsible homeowner and take care of your roof. One way to spot small problems before they turn into a huge hassle is to schedule an annual inspection with a licensed roofing professional. This roofer can notify you about required maintenance tasks. It’s also a good idea to schedule an inspection after a severe weather episode, like a storm with harsh winds, hail, or ice.

Finally, don’t forget to clean your gutters twice a year and make sure your roof has proper ventilation to prevent water damage.

Signs You Need to Replace Your Fiberglass Shingles

Just like any roofing material, fiberglass shingles don’t last forever. Here are some telltale signs that it’s time to schedule an inspection (which may lead to replacing your roof or repairing it):

  • Missing shingles: If you live in a climate that experiences tornado-like winds or harsh winters, it is normal to notice a few missing shingles. However, the sight of missing shingles is an obvious sign that it is time for a roof repair.
  • Curling, buckling, or cracked shingles: Shingles that are past their prime will start to lose their structure.
  • Shingles missing granules: Sometimes granules can fall off due to foot traffic on your roof or an extreme weather event; other times it’s just part of the normal aging process. If you notice granules in your gutters, call your roof inspector.
  • Discolored shingles: This is more than just an eyesore. It could be a sign of water damage, rot, or harmful algae and moss growth.
  • Water damage: If you notice a leak in the roof when it rains, you shouldn’t simply put a pan under it and ignore it until the next rainfall. Water damage can spread quickly and cause your roof to sag.
