PITCH Roofing is a locally owned and operated roofing company serving the state of Florida, and today we’re walking you through everything you need to know about fiberglass shingles. From shingle roof replacement costs to longevity and common repairs, keep reading for a complete breakdown of these popular roofing shingles.

What Are Fiberglass Roof Shingles?

What Are Fiberglass Roof Shingles

Fiberglass roof shingles are made using a very similar process to traditional asphalt shingles, with one important distinction. Old school asphalt shingles were made from organic mat base, then dipped into a thick layer of asphalt and topped with stone granules. Fiberglass roof shingles follow a similar process, with the notable exception that their base mat is made from fiberglass, not organic materials.

This may seem like a small change, but it makes a big difference. Because fiberglass is hardier, these shingles are less prone to bending or breaking, even during one of Florida’s infamous tropical storms. Fiberglass also provides improved resistance against UV rays, which could otherwise dry out and warp your roofing shingles.

Since its inception, fiberglass shingle roofing has taken the world by storm. But is it the right material for your next roof replacement? To determine that, we need to look at the good and the bad of fiberglass asphalt shingles.

Every roofing material has its upsides and downsides, including fiberglass roof shingles. That’s why PITCH is here to walk you through the pros and cons so you can make an informed decision. Keep reading for a detailed report on the good and bad of fiberglass asphalt shingles.

Pro: Low Shingle Roof Replacement Costs

Pro Low Shingle Roof Replacement Costs

If you want an affordable roof that can still do the job of protecting your home, fiberglass roof shingles are an excellent option. Without sacrificing quality, these roofs come with simple manufacturing and installation that keeps your costs low. But how much can you expect to pay for fiberglass roof shingles?

Quality, architectural fiberglass roof shingles cost between $4 and $9 per square foot for residential structures. So if your roof is 1,500 square feet, then you’re looking at fiberglass shingle roof replacement costs between $6,000 and $13,500.

Of course, this is just a range. For specific numbers, your contractors will need to figure in your roof’s slope, accessibility, roofing accessories, the state of your roof decking, and other important factors. That’s why the only way to get an exact number is through a personalized roof estimate.

Con: Middling Life Expectancy

When you get a new roof, you want it to last. While fiberglass roof shingles will last for some time, they just can’t compare with other sloped roofing materials. On average, fiberglass shingle roofs last 20 to 25 years in Florida.

This isn’t bad, but it’s nowhere near the 40 to 70 year lifespan of metal roofing or the up to 100 years of protection that clay tiles offer. And because you’ll need more frequent roof replacements, getting shingle roofs can cost you more in the long run. Still, fiberglass roof shingles will be able to protect your home for decades without breaking the bank, even if they don’t last as long as other options.

Pro: Wide Variety of Colors and Styles

Asphalt roof shingles are the most popular roofing material in North America. That means that there are a ton of options with regard to the type, style, and color of fiberglass roof shingles you can choose from. So no matter what style or aesthetic you’re looking for, you’ll always find a shingle option that suits your property and your tastes.

Con: Somewhat Common Roof Repairs

Fiberglass roof shingles really are built to last. They’re waterproof, wind-resistant, and even hold up well to Florida’s extreme UV rays. Even so, however, these shingles need repairs somewhat often when compared to other sloped roofing systems.

Some of the most common roof repairs fiberglass roof shingles include:

  • Shingles that have been partially or completely torn off by the wind
  • Cracked, curling shingles from drying out due to UV exposure
  • Leaks from damaged shingles
  • Nails that have been loosened by high winds
  • Moss or algae growth on old shingle roofs
