Flat roofing in King's Lynn, stripping out failed felt and replacing it with EPDM rubber or GRP fibreglass. Book a free survey with photographs and no call-out charge, and you get a fixed written price within 48 hours that already includes waste removal and any scaffolding the job needs. Charles calls every enquiry back the same day, so you are not left chasing a quote while the garage ceiling keeps dripping onto whatever is stored underneath it.
Garages, extensions and dormers
Across Gaywood, South Lynn and the streets around the town centre, flat roofs sit over garages, kitchen extensions, porches and dormer windows. Each one gives itself away differently. A dormer flat roof is hard to see from the ground, so the first sign of trouble is damp around a bedroom window or a stain on the ceiling below. A garage roof shows puddles that sit for days and felt split along the laps. An extension roof leaks where it meets the house wall, because the upstand has cracked away from the brickwork.
Rubber or fibreglass for your flat roof
Our two systems answer different problems. EPDM rubber goes down as one continuous sheet, which suits a large garage or a wide extension where the old felt failed at the joints. GRP fibreglass is built up and cured in place, giving a hard, crisp finish that suits roofs you step onto to clean windows, and roofs crowded with rooflights, vents and upstands. Both replace felt for good. At the survey we check how your roof drains, how it meets the wall and what state the deck is in, then recommend one with reasons.
Not every flat roof needs replacing. A torn upstand, a blocked outlet or one failed seam on a roof that is otherwise sound gets a repair quote, not a new roof. If the timber deck has gone spongy, we show you in the photos, because new membrane laid on a rotten deck fails fast. Our own crews do the work, never subcontractors, and the price you sign is the price you pay. Pitched roof needs looking at too? See roof repairs in King's Lynn.
We are rated 4.8 from 160+ reviews across Google, Trustatrader and Checkatrade, and our Peterborough team has King's Lynn as one of its busiest patches. Flat roofs and gutters fail together more often than you would think, so if the edge of your roof drains into a cracked or sagging gutter, we replace it in uPVC on the same job; see fascias, soffits and guttering.

Flat Roofing in King's Lynn, your questions answered
Can you replace a flat roof on a dormer in King's Lynn?
Yes. Dormer flat roofs are a regular part of our flat roofing work. We replace the felt with EPDM rubber or GRP fibreglass, finish the edges and upstands properly and include any scaffolding in the fixed written price. The survey is free and the quote arrives within 48 hours.
What is the difference between EPDM and GRP?
EPDM is a rubber membrane laid as a single sheet with no seams across the roof. GRP is fibreglass laid wet and cured hard into a tough, walkable surface. Both replace felt for good. We recommend the right one for your roof at the free survey and explain why in plain terms.
Will you tell me if my flat roof just needs a repair?
Yes. We do not upsell. If a split seam or a blocked outlet is the only fault on a sound roof, you get a repair quote. If the deck is rotten, the survey photos show you, so the decision is yours with the evidence in front of you.
EPDM or GRP, which is better?
Both outperform felt by miles. EPDM suits larger, simpler roofs and goes down fast; GRP gives a hard, walkable finish ideal for complex shapes and balconies. We will recommend the right one for your roof, not the one with the biggest margin.
