How Much Do Fiberglass Shingles Cost by Type?
Fiberglass shingles come in two primary types: Architectural shingles and 3-tab fiberglass shingles. Both types have their own distinct look and different price point to consider:
| Types of Fiberglass Shingles | Average Cost |
| Architectural Shingles | $4.50–$7 per square foot |
| 3-Tab Fiberglass Shingles | $1–$5 per square foot |
Architectural Shingles
As the most expensive type of fiberglass shingles, architectural shingles typically cost $4.50 to $7 per square foot. However, they can increase the value of your home and have a much longer life span of 30 to 50 years compared to traditional shingles. This type of shingle is often the standard for high-end homes because of its beautiful look and durability.
Pros
- Highly durable
- Usually last 30 years or more
- Can withstand strong winds
- Typically comes with a limited lifetime warranty
- Offered in many styles
Cons
- Expensive
- More complicated to install
Fiberglass Shingles
3-tab fiberglass shingles are the most affordable and widely used option. They cost $3 to $5 per square foot (or $300 to $500 per square) installed. Their name comes from the three cutouts, or “tabs,” that create the look of separate shingles despite being a single piece.
Pros
- Affordable
- Easy to install
- 15–20 year life span in mild climates
Cons
- Not as durable as other roofing materials
- Limited customization options
How Much Do Fiberglass Shingles Cost by Square Footage?
Whether you’re planning a DIY roofing project or hiring a professional, understanding the cost per square foot is essential. Fiberglass shingles cost $3 to $8.60 per square foot, but total pricing depends on your roof’s size and complexity.
To estimate costs, calculate your roof’s square footage (including overhangs and pitch adjustments), then use the table below for an approximate cost range.
| Roof Size | Typical Price Range | Average Cost |
| 1,000 sq. ft. | $4,750–$8,600 | $6,650 |
| 1,500 sq. ft. | $7,125–$12,900 | $9,975 |
| 2,000 sq. ft. | $9,500–$17,200 | $13,300 |
| 2,500 sq. ft. | $11,875–$21,500 | $16,625 |
| 3,000 sq. ft. | $14,250–$25,800 | $19,950 |
| 3,500 sq. ft. | $16,625–$30,100 | $23,275 |
| 4,000 sq. ft. | $19,000–$34,400 | $26,600 |
Which Factors Impact The Cost of a Fiberglass Shingles Roof?
While average costs provide a general estimate, several key factors determine how much you’ll actually pay for a fiberglass roof replacement.
Roofing Material
- Architectural fiberglass shingles cost $6–$10 per square foot, making a 1,500-square-foot roof range from $9,000 to $15,000. These shingles last longer and provide better durability and aesthetics.
- 3-tab fiberglass shingles are more affordable at $3–$5 per square foot, costing $4,500 to $7,500 for a 1,500-square-foot roof. However, they have a shorter lifespan and lower wind resistance.
Square Footage
The larger and steeper your roof, the more materials and labor will be required. Complex roof designs with multiple valleys, dormers, or chimneys also increase labor costs due to added installation time.
Location
Where you live affects taxes, the cost of labor, shipping costs, and even manufacturing costs. Remote areas may pay higher shipping costs for fiberglass shingles and other materials.
Professional Vs. DIY Fiberglass Shingles Installation Cost
Installing a fiberglass shingle roof is no small task. While a DIY project can save money, it requires specialized skills, tools, and a strong focus on safety.
However, hiring a professional to install your fiberglass shingles roof will be more expensive, with the average cost being around $19,950. A DIY project will only cost the price of the raw materials, which is approximately $13,500 for the same-size roof with architectural shingles.
Installing Fiberglass Shingles Yourself
A DIY installation may save you money, but consider these risks before attempting it:
- Safety Hazards: Roofing work requires climbing, lifting heavy materials, and working at heights. Falls are a serious risk.
- Specialized Tools Needed: A roofing nailer, shingle cutter, and safety harness are essential.
- Mistakes Can Be Costly: Incorrect installation may lead to leaks, void warranties, or require expensive repairs.
Best for: Experienced DIYers with roofing knowledge.
Hiring a Professional for Fiberglass Shingles Installation
Hiring a reputable roofer ensures proper installation, maximizing the lifespan and performance of your shingles. Here’s how to find the right contractor:
- Get Multiple Quotes – Compare at least 3 roofing companies to find the best pricing and service.
- Check Credentials – Ensure the contractor is licensed, insured, and experienced with fiberglass shingles.
- Ask About Warranties – A quality roofer should offer both manufacturer warranties (on materials) and labor warranties.
- Get Everything in Writing – Your contract should detail costs, timelines, materials, and warranty coverage.
If you live in a cold climate, consult a professional roofer before choosing your new shingles, as many fiberglass shingles don’t hold up well during prolonged low temperatures.
So, Are Fiberglass Shingles Worth the Investment?
For many homeowners, fiberglass shingles offer a solid balance of durability, affordability, and energy efficiency. They last 20 to 50 years, require minimal maintenance, and perform well in various climates.
Best for: Homeowners looking for a cost-effective, long-lasting roof with good fire and moisture resistance.
Not ideal for: Areas prone to extreme hail or homeowners who want a premium roofing material like metal or slate.
While fiberglass shingles have a higher upfront cost than standard asphalt shingles, they require fewer repairs and replacements over time—making them a smart investment for long-term savings. If you plan to stay in your home for 15+ years, a fiberglass roof can be well worth the price.

FAQs About Fiberglass Shingles
No, fiberglass shingles and traditional asphalt shingles are not the same. While both fall under the asphalt shingle category, they have key differences in composition and performance.
- Fiberglass shingles have a woven fiberglass mat at their core, making them lighter, more water-resistant, and more fire-resistant than organic asphalt shingles.
- Traditional asphalt shingles (also called organic shingles) have a felt or paper base, making them heavier and more absorbent, which can lead to warping over time.
Fiberglass shingles generally last longer and perform better in hot or humid climates, making them the preferred choice for modern roofing.
Fiberglass shingles vary in price depending on the type. 3-tab fiberglass shingles are the most affordable, typically costing $3 to $5 per square foot, while architectural fiberglass shingles range from $4.50 to $8.60 per square foot.
While high-end fiberglass shingles can be more expensive than basic asphalt shingles, they offer better durability, fire resistance, and longevity—making them a cost-effective investment for many homeowners. Most homeowners can find a fiberglass shingle option that fits their budget.
While fiberglass shingles are durable and lightweight, they do have some drawbacks:
- Cold Weather Sensitivity – In extremely cold climates, fiberglass shingles can become brittle and more prone to cracking.
- Less Impact Resistance – Compared to heavier asphalt or architectural shingles, fiberglass shingles may not hold up as well against hail or falling debris.
- Shorter Lifespan Than Premium Materials – While fiberglass shingles can last 20 to 50 years, they don’t match the longevity of materials like metal or slate.
That said, fiberglass shingles perform well in hot, humid, and fire-prone climates, making them a great choice depending on where you live.
