GRP Fibreglass Roofing
If you want a flat roof you can fit and completely forget about, GRP (Glass Reinforced Polyester) fibreglass is the gold standard. Applied as a cold liquid resin over a strong glass matting, it cures into a single, stone-hard skin across your entire roof—with zero heat or hot bitumen required.
Why Choose a GRP Fibreglass Roof?
-
100% Seamless Protection: Because it forms a single, continuous sheet, there are no joints, welds, or weak seams that can split or leak.
-
Tough & Foot-Traffic Ready: Incredibly impact-resistant and fire-retardant, making it strong enough to handle regular walking, heavy weather, or balcony use.
-
Sleek, Customisable Look: Available in a variety of smooth or non-slip finishes and colours to give your extension, garage, or porch a clean, modern style.
-
30+ Year Lifespan: With virtually zero ongoing maintenance needed, a GRP roof delivers outstanding long-term performance and peace of mind.
Multi-Layer Felt Roofing
High-performance felt roofing is still one of the most reliable, budget-friendly choices for garages, home extensions, and outdoor structures. Today’s modern torch-on felt is a huge leap forward from older materials, using tough, polyester-reinforced bitumen layers that stay flexible and watertight year after year.
Why Opt for Modern Torch-On Felt?
-
Triple-Layer Waterproofing: We lay down a robust three-tier system—a breathable base coat, a strong middle underlay, and a heavy-duty mineral top sheet—to keep rain completely locked out.
-
Built-In Sun Protection: The durable slate-granule finish shields the underlying bitumen from UV rays, preventing drying out, cracking, and premature wear.
-
Unbeatable Value: Delivers a great balance of affordability and strength, giving you up to 20 years of low-maintenance weather protection.
-
Flexible Styles: Available in clean green, grey, or charcoal mineral caps to blend naturally with your home’s exterior.
Our experienced roofers meticulously seal every seam to create a tough, weather-tight barrier that handles winter storms and summer heat with ease.

Andrew Vicars
Very good service and competitive rates. Quality Mark Roofing Ltd came out to have a look at the problem and were very clear about what area of our roof needed to be replaced with new tiling, and how much it would cost. We are very happy with the work carried out as the guttering is no longer leaking.
