Flat roofs require specialist knowledge and materials. We install and repair all types of flat roofing including modern GRP fibreglass and EPDM rubber systems. From garage roofs to large commercial installations, we deliver watertight results.
Flat roofs are common on extensions, garages, dormers and many commercial buildings across Haverhill and the surrounding villages. A flat roof that is failing rarely fails all at once — you will usually see pooling water, blistering, splits at the upstands, or damp patches on the ceiling below before it leaks properly. Caught early, a flat roof is one of the more straightforward roofs to put right; left too long, water tracks along the deck and the timber underneath has to be replaced too.
We install and repair all three modern flat-roof systems — GRP fibreglass, EPDM rubber and high-performance felt — and we will recommend the one that suits the span, the access and the budget rather than the one that is quickest to fit. For a small garage roof that is felt and tired, a single-ply or GRP overlay is often the sensible, cost-effective answer. For a larger extension where you want to fit and forget, EPDM or GRP laid on a properly prepared deck will outlast the felt it replaces several times over.
| Option | Pros | Cons | Typical lifespan |
|---|---|---|---|
| GRP fibreglass | Seamless, hard-wearing, walk-on; good for complex shapes | Needs dry weather to cure; higher labour cost | 25–30 years |
| EPDM rubber | Single sheet, very few joints; flexible in cold | Membrane can be punctured by heavy impact | 20–30 years |
| Felt (torch-on) | Lower cost; proven; good for small/awkward roofs | Shorter life; more joints than sheet systems | 15–20 years |
As a rough guide, a re-covered single garage flat roof typically runs from around £1,000–£2,500, with GRP around £80–£120/m² and EPDM around £60–£90/m² fitted, depending on access, insulation and how much decking needs replacing. Every job is different, so we always confirm with a free, no-obligation written quote before any work starts.
GRP (Glass Reinforced Plastic) is a seamless, highly durable flat roofing system. It's applied in liquid form and cures to create a watertight surface ideal for flat roofs, balconies, and garage roofs.
GRP fibreglass roofs last 25-30 years, EPDM rubber 20-25 years, and traditional felt 10-15 years. Proper installation and maintenance extend these lifespans.
Both are excellent choices. GRP offers a seamless, hard-wearing surface ideal for walkable areas. EPDM is flexible, UV-resistant, and often more cost-effective. We'll advise based on your needs.
Costs depend on size and material. GRP typically costs £80-120 per square metre, EPDM £60-90. A typical garage roof replacement ranges from £1,000-£2,500.
Yes, garage roof replacement is one of our most popular services. We offer GRP fibreglass, EPDM rubber, and felt options to suit your budget and requirements.
