Roof windows and Velux
Roof windows, fitted without leaks.
A roof window brings daylight into a loft, a landing or an extension. Fitted well, it stays watertight for decades. Fitted badly, it leaks from day one.
Most roof window leaks come from the flashing, not the glass. The window has to sit at the right height in the tiles and use the right flashing kit for the roof covering, with the membrane collar sealed behind it.
We fit new roof windows, replace old ones like for like (usually from inside, without scaffold), and reseal or reflash windows that have started to leak. We can also fit blinds and electric or solar openers while we are there.

Other roofing work we do
Roof repairs
Most leaks come down to one small failure: a slipped tile, a cracked ridge, a gap in the flashing.
Typically £180 to £950
New roofs and re-roofing
When repairs stop being worth it, we strip the roof back to the rafters and rebuild it with modern breathable membrane, treated battens and your choice of tile or slate..
Typically £6,500 to £19,500
Flat roofs
Most flat roofs fail at the edges and joints, not in the middle.
Typically £1,200 to £6,500
Chimney repairs and repointing
A chimney takes more weather than any other part of the house.
Typically £400 to £2,400
