How Much Does a New Roof Cost? The 7 Factors That Decide the Price
It is the most asked question in roofing and the one with the least straight answers online. So here is the honest version. As a rough national guide, a full roof replacement on a typical UK semi tends to land somewhere between £5,000 and £12,000, with terraces sometimes below that range and large detached or complex roofs above it. The spread is wide because seven factors move the number, and until a roofer has seen your roof, any figure is a guess.
1. The Size and Shape of the Roof
Size is obvious: more square metres means more materials and more labour. Shape matters just as much. A simple gable to gable roof with two plain slopes is the cheapest shape there is. Hips, valleys, dormers and multiple junctions all add cutting, detailing and leadwork, and detailing is where the skilled hours go.
2. The Covering You Choose
Concrete tiles sit at the affordable end. Clay tiles cost more. Natural slate costs more again, and premium slates or handmade clay sit at the top. The covering can swing the total by thousands on its own, which is why a quote should always state exactly which product is being priced.
3. What Is Underneath
A reroof is not just tiles. The battens and underlay are replaced as standard, and on older roofs there can be surprises beneath: rotten rafters, failed valley boards or chimney timberwork. A good roofer prices what can be seen and is upfront that hidden timber repairs, if found, are extra. Be wary of any quote that promises the unseen.
4. Access and Scaffolding
Scaffolding is a real and unavoidable cost on a full reroof, typically several hundred to a couple of thousand pounds depending on the property. Tight terraces, conservatories below the roofline and three storey homes all push access costs up.
5. Leadwork and Detailing
Chimneys, abutments and valleys need lead, and lead is both an expensive material and a skilled trade. A roof with two chimney stacks and three valleys carries meaningfully more cost than the same area of plain slope.
6. Disposal
Stripping a roof produces tonnes of waste, and skips and disposal fees are part of any honest quote. If a price seems oddly low, check whether disposal is actually included.
7. Who Is Doing It
Insurance, vetting, guarantees and experience all cost the contractor money, and they are reflected in the price. The cheapest quote on the table is usually missing one of them. Our guide on this blog about choosing a roofer covers exactly what to check.
