Build your roof. Watch the price move.
Material, size, roof shape, access, extras — the same things a roofer actually walks the job for, not just square footage. The price updates as you go, itemised, so you can see what's driving it. It’s a real starting point, not the final number; that always comes as a proper written quote.
What kind of job?
Material
Roughly how big?
Roof shape
More cuts, more junctions, more labour — a complex roof genuinely costs more to cover, not just more to look at.
How’s the access?
How long each material actually lasts
Typical UK lifespans (upper estimate shown) — yours will depend on installation, pitch and upkeep. More on each material →
Anything else while we’re there?
- Guttering clearance & check +£450
- Chimney flashing renewed +£280
- Loft insulation top-up to current Building Regs +£850
- Add a roof window (Velux-style) +£950
A full re-cover like this counts as “renovating a thermal element” under Building Regs Part L, which means bringing the insulation up to current standard where it’s feasible to — if your loft’s under that already, this is the one to tick.

This one’s priced per job, not by size — the range above is typical, and a real number needs a quick look at the job (a photo’s usually enough).
