What do flat rooflights in Renfrew involve?
For Renfrew 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.
Scottish weather is hard on roofs, so we specify rooflights and roof windows with exposure in mind and fit upstands with generous heights. Flat rooflights suit kitchen extensions, side returns and flat-roofed back rooms.
Renfrew sits about 3 km from Clydebank and 5 km from Erskine, and we cover the whole PA4 postcode district and the roads in between.
Options we can specify in Renfrew
- Insulated kerb or timber upstand built to suit
- Frame colours: anthracite, black, white or RAL
- Double or triple glazing
- Square, rectangular or long-format sizes
- Solar-control or self-cleaning outer pane
- Slim sightlines from inside — mostly glass, little frame
- Inner pane laminated for safety overhead
Before you order: points to check
- Needs a properly formed upstand — usually at least 150 mm above the finished roof surface (check the manufacturer's figure)
- The roof membrane must be dressed up the upstand before the unit goes on
Do you need permission in Renfrew?
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.
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.
See our building regulations guide for U-values, glazing limits and self-certification.

Common 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 a flat rooflight be walked on?
Not unless it is designed as a walk-on unit with structural laminated glass. A standard flat rooflight is for light only — if the roof is used as a terrace, choose a walk-on rooflight instead.
Double or triple glazing?
Double glazing suits most domestic jobs. Triple glazing improves thermal performance and cuts noise from rain, which is worth it over bedrooms or where the energy calculation is tight.
Do I need to be at home for the survey in Renfrew?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
