Which flat roofs are common in South Lanarkshire?
Flat roofs in South Lanarkshire sit on terraced streets with flat-roofed rear kitchens and bathrooms, lock-up garage blocks on estates and 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. Approximate 1991–2020 regional averages based on Met Office data.
Building standards in Scotland
In Scotland a building warrant is usually needed for alterations, structural work and new roofs; like-for-like repairs to a covering can be exempt. Section 6 of the technical handbooks sets a domestic roof benchmark of 0.12 W/m²K, applied as far as reasonably practicable on an existing roof. In South Lanarkshire the application goes to South Lanarkshire Council (building standards). More on the rules.
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.

Yes, where lead forms part of the dormer abutment or cheek flashings, we include renewing it in the roof job.
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.
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.
