What does a dormer roof in Lanark need?
High, exposed dormers in Lanark take the full force of the wind and rain. Edge trims loosen, flashings lift and the felt at the drip edge cracks. Once the faults spread around the perimeter, a new roof with fresh trims usually lasts far longer than another round of repairs.
In a town like Lanark, flat roofs are commonly found on 1930s semis with flat-roofed garages and kitchen extensions or low-rise post-war blocks of flats. 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 Lanark?
Guide price in Lanark: £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 |
|---|---|

| 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.
What's included?
- New membrane, drip trims and back-edge abutment under the tiles

- Free survey of the dormer roof, cheeks and main roof junction

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.

Does the room below need emptying?
No, but moving furniture away from the window and covering the floor is sensible. The room stays usable throughout.
