Lean-to conservatory tiled roof cost

Reviewed byZaib Khan
Updated onSeptember 2026

A tiled roof on a medium Lean-to conservatory typically costs £7,400 to £10,600, fitted.

Small£7,300£6,100 to £8,500
Medium£9,000£7,400 to £10,600
Large£11,200£9,300 to £13,100

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.

Tiled roofs on a Lean-to conservatory

Check the system minimum pitch against your roof. If the lean-to is shallow the installer may raise the wall plate on the house side or use a low pitch tile.

  • 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.
