Roofing
Repairing and replacing flat roofs on extensions, garages and dormers.
Flat roofs fail differently from pitched ones. Water sits rather than runs, so a small split or a poorly dressed edge can let in a lot of it, and the damage often spreads under the covering before it shows inside.
Splits, blisters, lifted edges and failed upstands around walls and roof lights, where the deck underneath is still sound.
Stripping the old covering and, where it has gone soft, the deck, then a new covering. We will explain the options for the material and why we suggest one for your roof.
Water standing on a flat roof long after rain is a sign the falls are wrong or the deck has sagged. Getting the water to drain is part of the fix.
Drip edges, upstands and the outlets into the gutter, which is where many flat roof leaks begin.
Everything else we do
Finding where the water is really getting in, and fixing that rather than the stain on the ceiling.

Replacing roof coverings on flat roofs is on the government's list of work that may need building regulations approval, and the roofing trade body's guidance says flat roof overlays are building work too. Check before work starts, or use a contractor who will handle it.

Usually because the roof does not fall enough towards its outlet, or the deck has sagged between joists. Some water after rain is normal for a short time; standing water that stays is ponding and shortens the life of the covering.
Sometimes, but an overlay is still building work and the old roof and deck have to be fit to take it. If the deck is wet or soft, it has to come off.
