What does a dormer roof in Omagh need?
If your dormer in Omagh was added years ago with a basic felt roof and little insulation, it will tend to fail at the edges first, and they leave the loft room cold in winter and hot in summer. A warm-roof replacement deals with both problems at once.
In a town like Omagh, flat roofs are commonly found on newer estates where the first extension roofs are now being replaced or 1960s and 1970s link-detached houses with flat-roofed garages and porches. Northern Ireland averages roughly 1,150 mm of rain a year, spread over many wet days, so a roof that sheds water quickly to clear outlets lasts far longer than one that holds puddles.
How much does a new dormer roof cost in Omagh?
At Northern Ireland guide rates, an 8 m² GRP dormer roof including scaffold comes to £1,250–£2,350 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 | £1,250–£2,350 |
| Single garage (18 m²), EPDM rubber | £1,400–£2,450 |
| Extension (20 m²), GRP, new deck + insulation | £2,650–£4,750 |
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?
- Strip-out of the old covering and deck repairs
- Free survey of the dormer roof, cheeks and main roof junction
- Scaffold with edge protection, priced in the quote
- Warm-roof insulation and a vapour control layer
Building control in Northern Ireland
In Northern Ireland, Technical Booklet F1 sets roof insulation at 0.18 W/m²K when a roof over a heated room is renovated or newly built, where that's feasible. The district council's building control should be contacted before work starts, and we prepare the details it asks for. More on the rules.

Can you replace the lead on my dormer at the same time?
Yes, where lead forms part of the dormer abutment or cheek flashings, we include renewing it in the roof job.

Yes, by the insulation thickness. We plan the build-up so the new roof still sits correctly under the main roof tiles at the back edge.
