What does a dormer roof in Aldershot need?
Buyers' surveys in Aldershot often flag dormer roofs, because they are hard to see from the ground and easy to neglect. A recent replacement, with building control sign-off where needed and written guarantees, answers that question before it becomes a problem in the sale.
Aldershot's flat roofs are mostly on terraced streets with flat-roofed rear kitchens and bathrooms, with plenty on shops with flat-roofed rear stores below flats too. 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 Aldershot?
Guide price in Aldershot: £1,550–£2,900 for an 8 m² GRP dormer roof including scaffold, including VAT at South East rates. 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
- Strip-out of the old covering and deck repairs
- New membrane, drip trims and back-edge abutment under the tiles
- Scaffold with edge protection, priced in the quote
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.

Is a dormer roof cheaper than a garage roof?
Not by as much as the size suggests. Scaffold and the extra detailing at height mean a small dormer roof often costs about the same as a single garage roof.
Can a dormer roof be replaced without scaffold?
Rarely. A tower or full scaffold is usually needed to give a safe working platform and edge protection at that height.
