Lean-to conservatory new polycarbonate roof cost
A new polycarbonate roof on a medium Lean-to conservatory typically costs £2,700 to £4,100, 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.
New polycarbonate roofs on a Lean-to conservatory
The cheapest roof on the cheapest shape: a new polycarbonate lean-to is often a one day job.
- 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.
