How we approach skylight replacement in Renfrew
Our skylight replacement service in Renfrew covers replacing tired domes and failed glass with a modern rooflight. Every job starts with a survey of the opening, the roof covering and the room below, and a fixed written price.
Many Scottish homes have dormers and attic rooms where an extra roof window adds light without a full dormer. In Renfrew, as anywhere, skylight replacement is the usual choice for yellowed domes, misted glass and leaking roof windows.
Neighbouring towns include Clydebank (3 km) and Erskine (5 km). We offer a survey date when we reply to your enquiry.

Do you need permission in Renfrew?
Scottish householder permitted development (Class 2B, other external alterations) can cover a rooflight that projects no more than 1 metre from the roof, but the right does not apply in conservation areas. Flats and tenements are outside householder permitted development, so check with the planning authority first.
Under the Scottish building standards, replacement rooflights should average 1.6 W/m²K or better, and no individual unit should exceed 3.3 W/m²K. Replacing a rooflight, frame included, does not need a building warrant, but the work must still meet the building standards.
