Fibreglass Roofers – Roofing is one of the most important elements of a building, protecting it from weather, improving insulation, and adding curb appeal. Among the many roofing materials available today, fiberglass roofing stands out for its durability, versatility, and long-term cost-effectiveness. If you are considering a fiberglass roof for your home or business, hiring skilled fiberglass roofers is essential to ensure quality workmanship and reliable performance.
This article explores everything you need to know about fiberglass roofers, including the benefits of fiberglass roofing, installation processes, costs, maintenance requirements, and how to choose the right contractor.
What is Fiberglass Roofing?
Fiberglass roofing is a type of roof covering made from reinforced plastic composites, typically a mixture of resin and fine glass fibers. When hardened, this material creates a strong, lightweight, and waterproof surface that can withstand harsh environmental conditions.
Fiberglass roofing is often applied as GRP roofing (Glass Reinforced Plastic), which is particularly popular in flat roofs. It is also widely used in industrial and commercial settings because of its resistance to corrosion, chemicals, and extreme temperatures.
Benefits of Fiberglass Roofing
Choosing fiberglass roofing offers many advantages over traditional roofing materials like asphalt shingles, felt, or metal. Skilled fiberglass roofers often highlight the following benefits to their clients:
Durability and Longevity
Fiberglass roofs can last 20–30 years with proper installation and maintenance. Unlike felt or tar roofs, fiberglass does not crack, warp, or blister under heat and weather changes.
Seamless Waterproofing
When applied by professional fiberglass roofers, GRP roofing forms a seamless layer that eliminates joints and weak spots where leaks usually occur. This makes fiberglass roofs especially popular for flat roof applications.
Low Maintenance
Fiberglass requires little upkeep compared to other materials. An occasional cleaning and inspection are usually enough to maintain performance.
Lightweight Material
Because fiberglass is lightweight, it reduces structural stress on the building. This makes it an excellent option for both new constructions and roof replacements.
Versatility
Fiberglass roofing can be molded into different shapes and customized with various finishes and colors. It is suitable for flat, pitched, and curved roofs.
Fire Resistance
Fiberglass has natural fire-retardant properties, adding an extra layer of safety for homes and commercial buildings.
Eco-Friendly Option
Compared to traditional asphalt shingles, fiberglass materials are more environmentally friendly, especially since they last longer and reduce replacement waste.
Applications of Fiberglass Roofing
Fiberglass roofing is suitable for a wide range of projects:
-
Residential flat roofs (garages, extensions, porches)
-
Commercial buildings (factories, warehouses, retail spaces)
-
Industrial structures exposed to chemicals or corrosive environments
-
Balconies, terraces, and walkways requiring waterproofing
-
Swimming pool covers and sheds
Professional fiberglass roofers adapt techniques and materials to fit the specific demands of each project.
The Fiberglass Roofing Installation Process
Hiring experienced fiberglass roofers is critical because proper installation ensures performance and longevity. Below is a step-by-step outline of how fiberglass roofers typically install a GRP roofing system:
Preparation of the Surface
The roof deck (usually made from plywood or OSB boards) must be clean, dry, and secure. Roofers check for rot, gaps, or uneven surfaces before starting.
Applying the Resin and Fiberglass Mat
A base resin layer is applied, followed by a fiberglass mat. The mat is then saturated with more resin using rollers to remove air bubbles and create a smooth, even surface.
Curing Process
The resin hardens to form a strong, waterproof membrane. Weather conditions such as temperature and humidity play a big role, so skilled roofers adjust materials accordingly.
Topcoat Application
A finishing topcoat is applied to seal the surface and add UV resistance, color, and texture.
Final Inspection
Professional roofers check for weak spots, seams, and imperfections before declaring the job complete.
Cost of Hiring Fiberglass Roofers
The cost of a fiberglass roofing project depends on several factors:
-
Size of the roof: Larger areas naturally cost more due to materials and labor.
-
Roof complexity: Curved or irregularly shaped roofs require more expertise.
-
Location: Labor rates vary depending on where you live.
-
Preparation work: Replacing old roofing materials or repairing decking increases costs.
On average, fiberglass roofing costs $7 to $12 per square foot installed. A typical flat roof replacement for a residential garage might range between $3,000 and $6,000, while larger commercial roofs could cost tens of thousands of dollars.
Maintenance and Care for Fiberglass Roofs
Fiberglass roofs are low-maintenance, but roofers usually recommend:
-
Regular Inspections: At least once or twice a year, plus after major storms.
-
Cleaning: Removing debris, moss, or algae buildup to avoid surface damage.
-
Quick Repairs: Addressing small cracks or chips early to prevent water seepage.
-
Re-coating: After 10–15 years, some fiberglass roofs may benefit from an additional topcoat to extend their lifespan.
How to Choose the Right Fiberglass Roofers
Hiring the right contractor makes the difference between a roof that lasts decades and one that fails prematurely. Here are key steps to finding reliable fiberglass roofers:
Check Experience and Specialization
Look for roofing companies that specifically list fiberglass or GRP roofing as one of their specialties. General roofers may not have the expertise needed for seamless application.
Review Licensing and Insurance
Ensure the roofer is licensed in your state and carries liability and workers’ compensation insurance. This protects both you and the workers.
Request References and Portfolio
Ask for photos of completed projects and speak to previous clients to gauge workmanship and reliability.
Compare Quotes
Get at least three written quotes. Compare not just price but also the quality of materials, warranty offers, and project timelines.
Check Warranties
A reputable fiberglass roofer should offer a workmanship warranty (5–10 years is common) in addition to the manufacturer’s material warranty.
Look for Local Reputation
Local fiberglass roofers are more familiar with climate conditions and building codes in your area. Plus, they are easier to contact for follow-up or maintenance.
Common Mistakes to Avoid
When hiring or working with fiberglass roofers, property owners should avoid:
-
Choosing the cheapest bid without considering experience and quality.
-
Skipping inspections and maintenance after installation.
-
Hiring unlicensed contractors who may cut corners.
-
Delaying repairs on small cracks or chips that can worsen over time.
The Future of Fiberglass Roofing
With advances in resin technology, fiberglass roofs are becoming even more durable, flexible, and eco-friendly. Some modern fiberglass systems incorporate solar panel compatibility, cool roof coatings, and green roofing options, making them a long-term sustainable choice. Skilled fiberglass roofers are continuously upgrading their techniques to meet these new demands.
Conclusion
Fiberglass roofing is a versatile, durable, and cost-effective solution for both residential and commercial buildings. Its seamless waterproofing, low maintenance needs, and long lifespan make it an attractive alternative to traditional roofing materials. However, the success of a fiberglass roofing project depends heavily on the expertise of the contractors you hire.
By choosing experienced and reputable fiberglass roofers, you ensure that your investment will provide decades of protection, energy efficiency, and peace of mind. Whether you are replacing an old flat roof, building a new extension, or upgrading a commercial property, fiberglass roofing—when installed by skilled professionals—can be one of the best choices you make for your property.
