EPDM rubber, GRP fibreglass and high-performance felt systems — installed properly with full guarantees.
Most flat roof failures aren't the material — they're the install. Poor falls, lazy detailing and cheap upstands cause leaks within years. We design every flat roof with proper drainage, full upstands, and seamless detailing into adjoining walls and chimneys.
Whether it's a single-ply EPDM rubber roof on a Hereford extension or a fibreglass GRP roof over a garage in Ledbury, you get a flat roof that genuinely lasts 20+ years, backed by both manufacturer and workmanship guarantees.
Honest, no-jargon answers from a working roofer in Herefordshire.
A properly installed modern flat roof should last 20–30 years. EPDM rubber and GRP fibreglass systems carry 20-year manufacturer guarantees and routinely last longer. Older mineral felt roofs typically last 10–15 years. The biggest factor is install quality — falls, upstands and detailing — which is where we spend most of our time on every job.
For most domestic Herefordshire flat roofs, EPDM rubber is the best all-round choice — single-piece, no joints, 20+ year life, and no smell during install. GRP fibreglass is excellent for balconies and walked-on areas. High-performance felt is the budget option but with a shorter lifespan. We'll recommend honestly based on your roof.
Often yes — splits, blisters and failed seams can be repaired if the rest of the membrane is sound. However, if the felt is over 15 years old, brittle, or has multiple failure points, a re-cover is usually more cost-effective long-term than chasing repeated leaks. We'll give you our honest opinion during the inspection.
The most common causes are failed upstands or flashing where the flat roof meets a wall, splits in old felt around skylights or vents, blocked outlets causing pooling, or perished mineral felt at edges. We diagnose the actual source rather than just patching the visible damp patch — which is often nowhere near the real leak.
Typical garage and extension flat roofs in Herefordshire range from £1,800 to £4,500 depending on size, material and access. Larger or more complex roofs with insulation upgrades, lanterns or multiple penetrations cost more. EPDM tends to sit mid-range; GRP slightly higher; felt slightly lower.

Yes — garage roofs are one of our most common flat-roof jobs across Herefordshire. We strip the old covering, inspect the deck, replace any rotten boards, and install your chosen system with new edge trims, drips and outlets. Most garage roofs are completed in 1–2 days.
Yes, and we'd usually recommend it during a re-cover. Adding warm-roof insulation (typically PIR boards) under the membrane dramatically improves energy efficiency, reduces condensation and brings older flat roofs up to current building regulations. We'll quote with and without if you'd like to compare.
For new flat roofing work, our typical lead time is 2–4 weeks across Herefordshire. For active leaks we attend much faster — often the same week — to make the roof watertight while the permanent install is scheduled.
