Flat rooflights in Paisley: what is involved?
For Paisley homes and buildings we offer flat rooflights: fixed double or triple glazed rooflights for flat roofs and extensions. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Stone villas, cottages and conservation areas across Scotland often call for conservation rooflights in slate roofs. Typical uses for flat rooflights include landings, bathrooms and rear extensions with flat roofs.
Paisley is the main town we list in Renfrewshire and Inverclyde; we also cover nearby Renfrew and Johnstone.
Choices for your Paisley project

Before you order: points to check
- Rooflights count toward glazing in an extension, which matters for Building Regulations energy and overheating rules
- New openings in an existing roof need a structural check on joists
Planning, building control and Paisley
Planning rules in Scotland differ: rooflights are treated as external alterations under Class 2B, with no permitted development in conservation areas. Listed buildings need listed building consent where the work affects their character.
Scottish energy standards for glazing, including rooflights, use an area-weighted average of 1.4–1.6 W/m²K in extensions, so most modern units comply comfortably. Forming a new opening normally involves structural work, so check with the local authority verifier whether a building warrant is needed.
Read the planning permission guide before you commit to a design.

Flat rooflights in Paisley: questions
Will it make the room too hot?
A big unglazed-to-sky area can add solar gain in summer. Solar-control glass, a blind, or pairing a fixed unit with an opening one keeps it comfortable.
Can you fit into my existing flat roof?
Yes. We form a new opening, trim the joists, build and waterproof an upstand and make good the ceiling. A survey confirms the joist direction and roof build-up first.
How long does it take?
Fitting into a prepared upstand usually takes a day. Forming a new opening in an existing roof, including making good inside, is often two to three days.
Do I need to be at home for the survey in Paisley?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
Can you work alongside my builder in Paisley?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
