If you’re looking for a roofing option that’s built to last and stands up to Durham’s wild weather, GRP roofing might be the perfect choice. GRP, also known as fibreglass roofing, has become increasingly popular with homeowners across the city.
At Roofing Durham, we’ve installed GRP roofs on everything from small extensions to large flat-roofed properties. Homeowners love GRP for its durability, seamless finish, and modern appearance.
What is GRP Roofing?
GRP stands for Glass Reinforced Plastic. It’s a high-performance material made from layers of fibreglass and special resins, finished with a protective topcoat.
This creates a smooth, strong, and completely waterproof surface — perfect for flat and low-pitch roofs often found on garages, extensions, and porches.
Why GRP Roofing is Ideal for Durham Homes
Weather Resistance
Durham sees its fair share of rain, wind, and occasional snow. GRP is designed to handle all of it without cracking, leaking, or blistering.
Seamless Finish
GRP roofs are installed without joints or seams, which are often weak points in other roofing systems. This makes them extremely watertight.
Long Lifespan
When properly installed, a GRP roof can last 25-30 years or more with minimal maintenance.
Modern Appearance
The sleek, smooth finish looks great on modern and traditional homes alike.
Low Maintenance
Unlike felt or asphalt, GRP doesn’t require regular re-coating or patching. Just an occasional clean and inspection will keep it in top shape.
Where is GRP Roofing Commonly Used?
At Roofing Durham, we often recommend GRP for:
- Garage roofs
- Home extensions
- Dormers
- Bay windows
- Porches
- Balconies and terraces
It’s especially useful where a flat or low-slope roof is needed.
Common GRP Roofing Problems (and How to Avoid Them)
While GRP is incredibly durable, poor installation is its biggest weakness.
Poor Surface Preparation
GRP must be laid on a dry, clean, and smooth surface. Any moisture or dirt can lead to blistering and leaks.
Incorrect Application
Applying the resin or fibreglass incorrectly can cause cracks or weak points.
Lack of Expansion Joints
In larger areas, expansion joints are necessary to allow for thermal movement.
At Roofing Durham, we make sure every GRP roof is installed to the highest standard to avoid these common pitfalls.
GRP vs Other Flat Roofing Options
GRP vs Felt Roofing
Felt is cheaper upfront but typically lasts 10-15 years and may require more maintenance.
GRP vs EPDM Rubber Roofing
EPDM is another excellent flat roofing choice, especially for larger areas. However, GRP offers a more rigid and smooth finish, ideal for smaller to medium-sized roofs.
GRP vs Asphalt Roofing
Asphalt has been used for decades but is heavier and less flexible than GRP. GRP is lighter and easier to maintain.
How Much Does GRP Roofing Cost in Durham?
GRP roofing costs vary depending on the size and complexity of the job. On average, homeowners in Durham can expect to pay between £70 to £100 per square metre.
