Lean-to conservatory glass roof cost
A glass roof on a medium Lean-to conservatory typically costs £3,500 to £5,600, fitted.
A lean-to has a single roof slope running down from the house wall, like a garden shed roof. It is the simplest roof to replace and usually the cheapest, but the slope and the house wall above it set some limits.
Glass roofs on a Lean-to conservatory
A glass lean-to is simple and fast. Rain run off is slower on shallow glass, so self cleaning coatings work less well on very flat roofs.
- A shallow slope matters for tiles: every tiled system has a minimum pitch, and a very flat lean-to may need a different tile, a slate effect finish, or a raised roof line.
- The new roof is sealed into the house wall with a flashing, so the height of any upstairs windows above it can limit how thick the new roof can be.
- One slope means one gutter run and no hips, which keeps labour low.
