About Our Flat Roofing (EPDM, GRP & Felt) Service
A flat roof is never actually flat — it needs a shallow fall built into the structure or firrings to shed water towards an outlet or gutter, and getting that fall wrong is the single biggest cause of a flat roof failing early through standing water and ponding. The three most common coverings each behave differently: EPDM (a single-sheet rubber membrane) is fitted with very few joints and copes well with movement; GRP (fibreglass, laid as a liquid resin that cures solid) gives a seamless, walkable surface well suited to roof terraces; and felt (built up in layers, either torch-applied or cold-adhered) remains a proven, cost-effective option when installed correctly with the right number of layers and properly dressed upstands and trims. Whichever covering is chosen, the detailing at upstands, rooflight kerbs and outlets is where most flat roofs actually fail if it is rushed.

Flat Roofing (EPDM, GRP & Felt) — Frequently Asked Questions
Each has its place: EPDM is a single sheet with minimal joints and handles movement well, GRP gives a seamless, walkable finish, and felt remains a proven option when installed with the right number of layers and correctly detailed. We'll recommend the right one for your specific roof during a free survey.
Ponding usually means the fall built into the roof structure is too shallow, uneven, or has settled over time so water can't reach the outlet. It puts extra strain on the membrane and shortens its life, so it's worth having assessed rather than left.
It depends on the size of the roof, the covering chosen, and how many upstands and outlets need detailing. Book a free roof survey for an accurate, no-obligation quote.
