Dome rooflights for Helensburgh: the essentials
For Helensburgh homes and buildings we offer dome rooflights: polycarbonate and acrylic domes for flat roofs, new or replacement. We measure first, specify to the opening and confirm any planning or building-control points before quoting.
Short winter days in Scotland make every square metre of overhead glass count, so rooflight sizing matters. Typical uses for dome rooflights include schools, flats and commercial flat roofs.
We cover all of Helensburgh and the G84 district, and nearby Greenock and Gourock.
Options we can specify in Helensburgh
- Fall-through protection mesh
- Clear, opal or tinted
- Polycarbonate or acrylic
- Fixed or hinged with vent
- Insulated PVC or GRP upstands
- Quick replacement on existing upstands
- Suits schools, flats and commercial roofs
Things we check at survey
- Plastic domes have a lower acoustic and thermal performance than glass
- Fire classification matters on some roofs
Rules and responsibilities in Helensburgh
On commercial roofs the main questions are usually building control, fire classification of rooflight materials and safe access rather than householder permitted development. We confirm the route for your building before ordering.
For non-domestic buildings in Scotland, the non-domestic Technical Handbook (section 6) sets the energy standards for rooflights; we supply the manufacturer's data for the building warrant. Fragile-roof safety and access are planned before work starts.
See our building regulations guide for U-values, glazing limits and self-certification.

Dome rooflights in Helensburgh: questions
Do domes leak?
Leaks are usually at the upstand seal or the membrane. Replacing the dome and resealing often fixes it.
Are domes safe to walk on?
No. Treat any rooflight as fragile unless it is specifically certified non-fragile, and never stand on it.
Can you replace just the dome?
Yes, if the upstand is sound and the size matches. Otherwise we replace both.
How do I book a survey in Helensburgh?
Send your postcode and, if you can, a photo of the roof and the room. We offer a survey date when we reply.
Do I need to be at home for the survey in Helensburgh?
Yes — someone needs to let us into the room below and, where possible, show us how the roof is reached.
