Straight answers
What sets the cost of a new roof
House type and size
A mid-terrace roof is around 45 to 60m². A detached house is 100 to 140m². Area drives most of the price.
The covering you choose
Concrete tiles cost £110 to £150 per m² fitted. Clay is £130 to £180 and natural slate £150 to £220, but slate lasts 80 years and more.
Scaffold
A full re-roof needs scaffold round the house. That is £800 to £1,500 on a semi and more on a detached or a third storey.
Timbers and battens
Rotten timber is replaced while the roof is open. You see it and agree it before we do it.
Waste
Stripping a roof fills skips. Waste removal is £300 to £500 and it is in our price, not a surprise at the end.
