Sun tunnels & tubular skylights in Johnstone: what is involved?
Our sun tunnels & tubular skylights service in Johnstone covers light pipes that bring daylight to halls and bathrooms with no window. 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 Johnstone, as anywhere, sun tunnels & tubular skylights are the usual choice for small internal rooms where a full rooflight will not fit.
From Johnstone to Paisley, Erskine and Renfrew, the same survey-first process applies: measure, specify, fix the price, then fit.

Do you need permission in Johnstone?
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.
Scotland's Technical Handbook (section 6) asks for windows, doors and rooflights in an extension to average 1.4–1.6 W/m²K, with no single unit worse than 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
Do sun tunnels need planning permission?
Usually not on a house, provided the dome does not project too far and the property is not listed. Check if you live in a conservation area or a flat.
Rigid or flexible tube?
Rigid tubes carry much more light. Flexible tubes are easier where the loft is cluttered, but lose light faster.
Can it go through a flat roof?
Yes, with a flat-roof flashing and upstand.
Do I need to be at home for the survey in Johnstone?
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 Johnstone?
Yes. On new extensions we fit once the opening and upstand are ready and coordinate dates with your builder.
