What does a dormer roof in Hastings need?
In Hastings, as anywhere, it often makes sense to replace a dormer roof while scaffold is already up for other work, such as new windows, rendering or repairs to the main roof. Sharing the scaffold keeps costs down and means every edge of the dormer can be checked at the same time.
In and around Hastings, flat roofs are typically found on 1930s semis with flat-roofed garages and kitchen extensions, and on lock-up garage blocks on estates. Much of the South East sits in the drier Thames catchment at roughly 730 mm of rain a year, so the usual failures are at joints, upstands and outlets rather than from sheer volume of rain.
How much does a new dormer roof cost in Hastings?
At South East guide rates, an 8 m² GRP dormer roof including scaffold comes to £1,550–£2,900 including VAT. The fixed price comes after a free survey for new and replacement roofs.
| Job | Guide price inc VAT |
|---|---|
| Dormer (8 m²), GRP, scaffold | £1,550–£2,900 |
| Single garage (18 m²), EPDM rubber | £1,750–£3,100 |
| Extension (20 m²), GRP, new deck + insulation | £3,300–£5,900 |
How long does a dormer roof replacement take?
The roofing itself typically takes one to three days, with scaffold going up before and coming down after. Allow a few extra days overall for the scaffold.
The room under the dormer stays usable, though it will be noisy during the strip-out, and dust can fall through gaps around the ceiling. Moving furniture away from the window helps. Scaffold usually needs space on the drive or garden, and sometimes a pavement licence. GRP has a strong smell while it cures, so keep the dormer windows shut on the day it is laid.
What's included?
- Warm-roof insulation and a vapour control layer
- New membrane, drip trims and back-edge abutment under the tiles
- Strip-out of the old covering and deck repairs
- Written workmanship guarantee, with building control handled where needed
Building regulations in England
Replacing more than half of a flat roof over a heated room usually counts as renovating a thermal element, so the roof is insulated to around 0.16 W/m²K where that's technically and economically feasible, and the work is notified to building control: the council or a registered building control approver, unless a registered competent person self-certifies it. A roof on a new extension is built to 0.15 W/m²K. Patch repairs, and most unheated detached garages, don't trigger the upgrade. Structural changes, or a new covering that adds 15% or more to the roof's weight, also need approval. More on the rules.
