The following factors affect the cost to install or replace a fiberglass shingle roof:

  • Roof size and shape – Multiple stories, skylights, dormers, chimneys, and complex roof shapes increase the cost.

  • Roof slope and pitch – Fiberglass shingles are suitable for roofs with a pitch of 4:12 or steeper. Installation costs more for roofs with steep pitches due to the extra safety precautions required.

  • Shingle type and style – Architectural/dimensional shingles cost more than standard 3-tab shingles but last longer.

  • Brand – Premium shingles from brands like GAF and CertainTeed cost more but are more durable.

  • Climate – Algae- and fungus-resistant shingles typically cost 5% to 15% more but are ideal for homes in climates with high humidity or heavy rainfall.

  • Old roof removal – Removing an old shingle roof costs $1 to $3 per square foot, depending on the number of layers.

  • Sheathing / underlaymentRoofing underlayment costs $0.10 to $0.80 per square foot, depending on if it is felt or synthetic. Roof replacement estimates typically include a new underlayment.

  • Flashing – Roof flashing is a thin piece of sheet metal installed in areas prone to leaks, such as roof valleys, chimneys, and intersections between two perpendicular roof surfaces. Most installers include new flashing in the estimate.

  • Rafters or trussesRoof framing costs $5 to $14 per square foot installed or $60 to $500 per truss for materials.

  • Roof decking Replacing the roof decking costs $2 to $5 per square foot and may be required if the existing decking is weak or damaged.

  • Roof repairs – Minor roof repairs cost $150 to $400 to patch small leaks, while structural repairs to fix a sagging roof cost $1,000 to $3,000.

  • Pipe boots / VentilationInstalling a roof vent costs $200 to $700.

  • Soffits and fascia replacementSoffit replacement costs $4 to $22 per linear foot. Replacing the fascia board costs $5 to $12 per linear foot.

  • Gutter installation/replacementGutter installation costs $5 to $15 per linear foot, while gutter replacement costs $6 to $17 per linear foot.

  • Drip edge – Adding a drip edge costs $1.50 to $3.00 per linear foot and prevents water from getting behind the gutters and rotting the roof decking.

  • Permits – Roof replacement permits cost $100 to $500, depending on location.

  • Slate tile or wood shake roof – Fiberglass shingles can simulate the look of natural slate tile or wood shakes at a fraction of the cost. Slate roof installation costs $1,000 to $3,000 per square, while wood shake roof installation costs $700 to $1,500 per square.

Fiberglass shingles FAQs

How long does an asphalt fiberglass roof last?

An asphalt fiberglass shingle roof lasts 15 to 30 years with proper maintenance, depending on the shingle style, climate, and amount of direct sun exposure. Fiberglass shingles have a lower life expectancy in areas with freezing climates, excessive heat, or extreme temperature changes.

Roof cleaning costs $250 to $600. Have the roof cleaned every 1 to 3 years to extend its lifespan.

What are fiberglass roof shingles made of?

Fiberglass roof shingles feature a woven fiberglass base mat sealed with a waterproof asphalt coating and topped with ceramic granules to add color, texture, and UV protection.

Do asphalt shingles contain fiberglass? {#fiberglass)

Fiberglass shingles have a fiberglass base mat coated with asphalt, but they contain 40% to 50% less asphalt than older organic asphalt shingles. Manufacturers stopped producing organic asphalt shingles in 2008, and all asphalt shingles manufactured today use fiberglass.

Can you walk on a fiberglass shingle roof?

Yes, you can walk on a fiberglass roof if the roof decking is stable. Avoid walking on the roof unless necessary as it may dislodge the granules on the shingles and cause the roof to deteriorate more quickly.

Do fiberglass shingle roofs crack?

Fiberglass shingles typically become more brittle with age and may crack or warp with frequent exposure to freezing temperatures.
