Flat roof repairs and replacements across West Malling and the surrounding Kent area. GRP fibreglass, EPDM rubber and felt systems for extensions, garages and outbuildings. Free quotes, 10-year guarantee.
Flat roofs are common on properties across West Malling — on rear kitchen and living room extensions, detached garages, bay window tops and first-floor flat-roofed additions. The Georgian, Victorian and 1980s-90s housing stock in West Malling, including the Georgian townhouses in the conservation area and modern estates at Kings Hill found on the High Street conservation area, Kings Hill and Addington, generates a steady demand for flat roof maintenance and replacement. Slightly elevated on the Kent Downs scarp, exposed to west and south-west wind-driven rain means flat roof membranes are under more stress here than in drier locations — and felt service life is shorter than manufacturers' figures suggest.
We install and repair GRP fibreglass, EPDM rubber and high-performance felt flat roofing across West Malling. GRP is our standard recommendation for most domestic applications — it's seamless, durable and handles the Kent climate's thermal cycling well. EPDM is specified on larger roofs over 30 square metres. All our flat roof installations carry a 10-year workmanship guarantee.
Whether repair or replacement is the right call depends on the condition of the existing roof deck and membrane. If the deck timber is sound and the covering has failed — common on Georgian, Victorian and 1980s-90s West Malling properties where original felt has reached end of life — a recover (new membrane over existing substrate) is often possible without full strip-out, reducing cost and disruption. We assess the deck condition before recommending either approach. If the deck is compromised by water ingress, full replacement is the correct solution.
GRP fibreglass is now the standard flat roofing specification for domestic extensions and garages across West Malling and Kent. The seamless installation eliminates the joint failures that are the most common cause of felt flat roof leaks. It handles foot traffic, is resistant to ponding water, and performs well through the temperature range seen across Kent. A well-installed GRP flat roof in West Malling should give 25–40 years of leak-free service.
Typical cost: £800 – £6,000 — depending on size and system. Average kitchen extension (20–30 sq m) in West Malling typically £1,200–£2,500 in GRP.

Yes, if the deck is sound. We assess the condition of the existing roof deck before recommending repair or full replacement. Many West Malling properties have flat roofs where the deck is still good but the covering has failed.
Replacing a flat roof like-for-like doesn't require planning permission. Changing from pitched to flat, or significantly altering the roofline, may require consent. Conservation area properties may have restrictions. We advise before quoting.
Only if the deck is sound and dry. We probe and moisture-test every deck at survey, because a new covering over a wet deck fails within a few years.
Yes. Where the fall is inadequate we specify a tapered insulation system to create the correct gradient, which removes the ponding permanently rather than just re-covering over it.
No. Surveys and written quotes across West Malling are free with no obligation, and we provide a written report of the roof condition either way.
No call-out fees. No obligation. Honest pricing from a local Kent roofer.
