A Lighter Roof That Still Stands Firm
Fiberglass Roofing in the Twin Cities for Aging Shingles That Are Cracking, Curling, or Blowing Off
A fiberglass shingle roof lies flat, holds its granules, and stays put in strong wind long after older organic-mat shingles would have started to curl. Barnhouse Exteriors installs, replaces, and repairs fiberglass-reinforced asphalt shingles to give homes that kind of stable, low-maintenance roof. Homeowners in the Twin Cities typically call when shingles crack, curl, or go missing after a storm.
Fiberglass shingles are built on a glass mat coated in asphalt, which makes them lighter than older felt-based shingles and gives them a Class A fire rating. Replacement includes complete removal of the old roofing, deck repair, ice and water barrier, underlayment, flashing, and balanced ventilation before the new shingles go down.

What Fiberglass Shingles Actually Do Differently
The glass mat does not absorb water the way older organic felt mats did, so the shingle resists swelling, blistering, and rot. You can choose architectural fiberglass shingles for a dimensional look, along with impact-resistant and wind-rated versions in a wide range of colors.
Once the new roof is on, you stop seeing loose granules in the downspouts and shingle edges lifting along the rakes. The roof holds a consistent color across every slope, and the attic stays dry under the deck.
Many older homes still carry organic-mat shingles, which are heavier and absorb water, and those roofs are fully removed rather than covered over. Manufacturer-backed warranties apply to the fiberglass shingles installed, and energy-efficient options with reflective granules are available for homeowners who want a cooler attic.
What to Know About Fiberglass Shingle Work
These answers cover the material, the installation, and what to look for afterward.
What is a fiberglass shingle made of?
It has a fiberglass mat core saturated and coated with asphalt, then surfaced with ceramic-coated mineral granules. The mat gives the shingle strength without the weight of a felt base.
How can you tell if your current roof has organic or fiberglass shingles?
Organic shingles are thicker and heavier, and they tend to curl and blister as they age. A roofing inspection identifies the type by checking shingle edges and weight.
Why is ice and water barrier installed under fiberglass shingles?
The barrier is a self-adhering membrane placed at eaves, valleys, and around penetrations where water can back up under shingles. It seals around each nail so trapped water cannot reach the deck.
How do older Twin Cities roofs affect a fiberglass replacement?
Many older roofs in the Twin Cities have multiple shingle layers and aging deck boards, so the tear-off often reveals sheathing that needs replacement. Fixing it first gives the new shingles a flat, solid base.
What should you check on a finished fiberglass roof?
Look for straight courses, sealed tabs that do not lift when pressed, and flashing that sits tight at walls and chimneys. Ridge vents should run evenly along the peak with matching cap shingles.
