Brighton has a flat roof on almost every street. Victorian terraces carry them on their two-storey back additions, Regency houses hide them behind the front parapet, and the inter-war semis on the edge of the city have them on garages, side extensions and loft dormers. Most were last covered decades ago, and many have had a new layer of felt laid straight over the old one.
When a roof like that fails, the covering has split, the deck underneath has gone soft, and the leak shows up on a kitchen ceiling a metre away from where the water gets in. We strip it back to the joists, put down a new deck and lay one system properly, finished with new upstands, flashings and edge trims.
Tight terraces on steep streets, most with a two-storey back addition and a later kitchen extension behind it. The flat roof often sits right under a bedroom window, so it gets stood on, and the joint where it meets the main wall is where it leaks.
Tall stucco houses with roofs hidden behind parapets: flat sections, valley gutters and box gutters that cannot be seen from the street. Leaks here run a long way inside the walls before they show, so we trace them from the roof and the top floor.
Edwardian and inter-war houses with bay tops, rear extensions and loft conversions with flat-roofed dormers. Dormer cheeks and the flat top meet at an upstand that needs dressing properly, or the rain gets behind it.
1930s semis and bungalows with flat-roofed garages, porches and side extensions. Many are still on their original felt, laid on chipboard that swells once water gets in, so the roof sags and holds puddles after every storm.
Brighton gets its weather straight off the Channel. South-westerly gales drive rain sideways into upstands and under edge trims, salt air dries out old felt and mastic, and the sun on a south-facing extension cracks a cap sheet that has lost its mineral finish. Roofs with too little fall hold water for days, and ponding is the fastest way to wear out any covering.
The signs to look for from an upstairs window: blisters and bubbles in the felt, splits along the edge trims, puddles that are still there two days after rain, moss growing in the low spots, and a soft or springy feel near the house wall. Inside, a stain on the ceiling under the extension or damp coming down the wall below the upstand means water is already in the deck.

William gets up to the roof, checks the deck, the falls and the joint to the house, and looks inside where the water shows.

The old covering and boards come off, any rotten joists are replaced and a new OSB deck goes down.

A lot of Brighton's terraces have no back access, so the old roof comes out and the new materials go in through the house. We sheet the floors and stairs, keep the mess to the route we agreed with you and clear up at the end of every day.
Most of central Brighton sits inside a controlled parking zone, and a skip or scaffold standing on the road needs a licence from Brighton & Hove City Council. We look at the street when we survey the roof and tell you in the quote if your job needs one.
Brighton has dozens of conservation areas. Re-covering an existing flat roof like for like does not usually need planning permission, but changing its shape, raising it or adding a roof terrace can, and listed buildings need consent for most changes. If your roof falls into one of those, we tell you before you sign anything.
Our flat roof cost guide gives the 2026 ranges we work to: about £1,200 to £2,500 for a single garage and about £2,000 to £4,500 for a rear extension of 15 to 25 square metres, both with a new deck. Each rooflight built in adds about £400 to £900. The deck, the height and the access move the price more than the choice of felt, rubber or fibreglass, which is why every quote comes after we have seen the roof.

Yes. When there is no back access, the job goes through the house: floors and stairs are sheeted and the old roof comes out the same way.
Not usually for a like-for-like re-cover. Raising the roof, changing its shape, adding a terrace or working on a listed building can need permission, and we tell you at the survey.
Only if the skip or scaffold has to stand on the road. Brighton & Hove City Council licenses both, and we tell you in the quote if your street needs one.
A garage or small back addition is usually one day. A larger extension, or a roof that needs new joists, takes two to three days.
Often, yes, if the deck is still sound. We check it first and tell you straight whether a repair will last or the roof needs replacing.
