Flat roofs on the Fen

On flat, open land, a flat roof gets no shelter. Wind off the Wash catches the edges of old felt and peels it back, and driving rain finds every lifted lap and cracked upstand. Garages and bungalow extensions across Spalding, Pinchbeck, Holbeach and Long Sutton follow a familiar pattern: felt blistering in the summer sun, splitting in the frost and tearing at the edge trim after a gale. Once water reaches the deck, the boards soften, the roof starts to sag, and puddles form that never drain away.

Why we replace felt with EPDM or GRP

Felt fails at its joints and edges, which is exactly where Fen wind attacks it. EPDM rubber goes down as a single sheet bonded to the deck, with edges trimmed and fixed so the wind has nothing to grip. GRP fibreglass is laid in place and cures into one hard skin, which suits extension roofs with rooflights and dormers with tight upstands. Both remove the seams that failed on your old roof. We recommend the system that suits your roof at the survey and explain why in the written quote.

If the deck is firm and the fault is one split or a blocked outlet, you get a repair quote, not a new roof. We do not upsell. Where the boards have gone soft, a patch will not hold, and the survey photographs show you why before you decide. Our teams of more than 20 roofers keep jobs short, and every one of them is ours. Pitched roof leaking in the wind as well? See emergency roof repairs in Spalding for how we find and fix it.

We are rated 4.8 from 160+ reviews across Google, Trustatrader and Checkatrade, from more than 1,000 projects over 25+ years. Working further out in South Holland? Our Holbeach roofers page covers the villages east of town. If your flat roof drains into a sagging gutter, we replace it in uPVC on the same job; see fascias, soffits and guttering.

Flat Roofing in Spalding, your questions answered

Can you replace the flat roof on my bungalow extension in Spalding?

Yes. We strip the old felt, check the deck and fit EPDM rubber or GRP fibreglass, finished with proper edge trims and upstands. The survey is free with no call-out charge, and your fixed written price arrives within 48 hours with waste removal included.

Why does my felt roof keep lifting at the edges?

Wind off the Wash gets under the edge of old felt and works it loose, especially where the edge trim has failed. Each lift lets rain in and weakens the next section. Replacing felt with a single EPDM sheet or a GRP skin with fixed trims removes the loose edge the wind was catching.

Is my flat roof worth repairing instead of replacing?

When the deck is firm and the fault is a single split, a lifted trim or a blocked outlet, a repair is the right call and that is what we quote. Soft, sagging boards mean a patch will fail. The survey photographs show which you have before you spend anything.

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.
