How much does it cost to re-roof a house?
Re-roofing is priced by roof area. Enter your roof size below for a region-adjusted estimate covering strip-out, membrane, battens and new tiles.
What a re-roof includes
- 1Strip and dispose
Remove the old covering and battens, with skips or muck-away.
- 2Membrane and battens
New breathable membrane and treated battens before the covering goes on.
- 3New covering
Concrete interlocking tiles are the value option (~10 tiles/m²); natural slate costs considerably more.
- 4Scaffolding and access
Scaffold to the elevations is a real cost — factor it in alongside ridge, verge and flashings.
Roofing is one of the biggest unknowns a surveyor flags, which is why heavy-refurb lenders like to see it costed explicitly. If only part of the roof needs work, a repair allowance may be more appropriate than a full re-roof.
