What does a dormer roof in Ayr need?
In Ayr, 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 a town like Ayr, flat roofs are commonly found on 1930s semis with flat-roofed garages and kitchen extensions or terraced streets with flat-roofed rear kitchens and bathrooms. Scotland averages roughly 1,570 mm of rain a year, with the west far wetter than the east, so drainage, falls and wind uplift are part of every specification we write.
How much does a new dormer roof cost in Ayr?
Guide price in Ayr: £1,350–£2,500 for an 8 m² GRP dormer roof including scaffold, including VAT at Scotland rates. The fixed price comes after a free survey for new and replacement roofs.
| Job | Guide price inc VAT |
|---|---|
| Dormer (8 m²), GRP, scaffold | £1,350–£2,500 |
| Single garage (18 m²), EPDM rubber | £1,500–£2,650 |
| Extension (20 m²), GRP, new deck + insulation | £2,850–£5,100 |
Is GRP or EPDM better on a dormer roof?
GRP fibreglass is often the first choice on a dormer, because it is laid as a liquid resin over a mat and forms neat, rigid edges, corners and drip details on a small roof. It cures to a hard surface that copes with occasional foot traffic during window cleaning or maintenance.
EPDM rubber works well on a plain rectangular dormer and can usually be laid as one sheet, with no field joins. Unlike GRP, it does not depend on resin curing conditions on the day. Torch-on felt can be used, but working a torch close to timber cladding, fascias and tiles needs extra care, so a cold-applied system is often chosen instead.
We recommend the system after surveying the dormer, its edges and how it meets the main roof.

Building standards in Scotland
In Scotland the building standards technical handbooks (Section 6 for energy) apply, and the council's building standards service decides whether a building warrant is needed. Like-for-like repairs to a roof covering can be exempt; alterations, structural work and new roofs usually need a warrant before work starts. The domestic roof benchmark is 0.12 W/m²K, applied as far as reasonably practicable on an existing roof. More on the rules.

Will insulating my dormer roof make it higher?
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.
Why does my dormer leak at the back where it meets the roof?
That junction is the most common leak point, usually because the upstand or flashing under the tiles has failed. A proper re-roof rebuilds it.
