Because two roofs that look alike from the street can need very different amounts of work once you are on them. These are the factors that move the price:
Most roof repairs — slipped or cracked tiles, a small leak, a section of flashing — start from around £150. A minor repair with no scaffolding is typically £150–£350; a larger repair that needs scaffold, such as ridge tiles or chimney flashing, is £350–£900+. We give you a free written price after seeing the roof, so you know the exact cost before any work starts.
A full re-roof on a typical semi-detached house is £4,000–£6,500 with concrete or clay tiles; a detached house is £6,000–£9,000+ depending on its footprint and the tile chosen. The final figure depends on the size and pitch of the roof, the covering, and whether any timber needs renewing once the old tiles are off, so we inspect first and give a free, itemised written quote.
Flat roofs start from around £895. A felt (torch-on) roof on a garage or extension is typically £895–£1,500; a longer-life GRP fibreglass or EPDM rubber roof is £1,200–£3,500+ depending on size. We recommend the right system for the roof and quote it free after measuring up.
Minor chimney work — small repairs to pointing, flaunching or a new lead flashing — starts from around £150; a full repoint is typically £350–£800. A rebuild is quoted individually after we have assessed the stack. The quote is free and in writing either way.
Velux and roof-window installation starts from around £695 and is typically £695–£1,800 supplied and fitted, depending on the window size and the roof. We quote it free once we know the size and position.
Roofline repairs start from around £150. A full uPVC roofline replacement — fascias, soffits and guttering — is typically £800–£2,500, priced by the length of roofline and the access needed. We give a free fixed quote after measuring up.
They are close on price, and both sit in the £1,200–£3,500+ band for a typical garage or extension. EPDM rubber is quick to fit and very durable on low pitches; GRP fibreglass gives a seamless, hard-wearing finish and suits roofs that get walked on. We advise which suits your roof and can quote both so you can compare.
A drone roof survey is free when it is part of a quote on a roof you own. A stand-alone pre-purchase survey — for a house you are thinking of buying — is £149, and you get the photographs so you can see the condition of the roof before you commit.
No. Every quote is free and carries no obligation, and there is no charge for coming out to look at the roof before quoting.
Five things: the size and pitch of the roof; the covering you choose (concrete interlocking tiles are the cheapest, clay plain tiles and natural slate cost more); how much scaffolding is needed; the condition of the battens and rafters underneath, which only shows fully once the old covering is off; and how easy the roof is to reach for materials and waste.
Four things move a terrace re-roof up or down. Party walls: each abutment needs new lead soakers and flashings, and the join to the neighbours' roofs has to be made cleanly. Chimneys: shared stacks often need repointing or rebuilding while the scaffold is up. The change of covering: swapping old slate for concrete tiles adds weight, so the rafters are checked and sometimes strengthened, and new battens and breathable underlay are always needed. Access: a scaffold on a street frontage or in a narrow rear yard, and a skip permit if the skip has to sit on the road. A mid-terrace roof is smaller than a semi's, so the price is often below the typical semi range — but only an inspection can say by how much.
We will assess the roof, explain everything clearly, and give you a fixed written price with no hidden extras.
