Areas around Dumbarton we cover
Dumbarton and the districts around it, G82, G83 and G60, all sit inside our working area. So does the ground between Dumbarton and Vale of Leven (2 miles), and on towards Erskine (6 miles). When a fitting team is booked, their travel is already in the quoted price, so it does not turn up as a surprise line on the final bill.
Already bought your unit?
Supply and fit tends to suit people who would rather not pick a unit from a catalogue. We look at the roof, the opening and how you use the room, then put a conservation rooflight on the quote that fits all three. Fit-only suits people who already know what they want, or have one on site. We are happy with either. The difference is who stands behind what: on fit-only, the maker or retailer covers the product, and our workmanship guarantee covers the installation.
On the day, we cover
- Slates or tiles lifted carefully and kept for reuse where possible
- Rooflight set low so it sits close to the line of the roof
- Position checked against any consent drawings or council conditions
- Conservation area rules by nation — We check the permitted development position for your nation before the rooflight is ordered.
- Reusing the original covering — We plan to reuse the existing slates or tiles wherever we can.
What happens on the day
Fitting days start with a look at the sky. If rain is due, the order of work changes so the roof is never left open to it. A typical day for a conservation rooflight runs like this: set up access, protect the room, open up the roof or prepare the existing kerb or frame, check sizes, fix, seal, then finish inside. On jobs that take more than a day, the opening is weather-sealed overnight. The last hour goes on tidying, waste removal and a walk-round with you.
Regulations for Dumbarton properties
For Scottish homes: building warrant for new rooflight openings; no warrant for replacing a rooflight complete with its frame, provided it meets the standards, including 1.6 W/m²K; planning permission in conservation areas and listed building consent for listed properties. Outside those, permitted development usually covers house rooflights, but the planning authority has the final word, so we check before you commit.
What to send for a quick quote
For fit-only work, the product details matter most: the link, the spec sheet, or a photo of the label on the box. Alongside that, send pictures of the roof and the ceiling below, approximate opening sizes, the type of roof covering, and how someone would get onto the roof. For supply and fit, the same photos and sizes do the job. Finish with your postcode, such as G82.
Common questions in Dumbarton
Do you offer trade rates for builders and roofers?
We carry out subcontract fitting for builders, roofers, extension companies and commercial contractors. Pricing is per job or per schedule of units, agreed in writing before we start. We can work to your programme, fit on your upstand or build our own, and leave the opening ready for the next trade. Send drawings or a unit schedule and we will come back with a trade quote.
Does a rooflight need a building warrant?
In Scotland a new rooflight needs a building warrant from the council before work starts. Replacing a rooflight complete with its frame doesn't need a warrant, but the new unit must meet the building standards in full, including 1.6 W/m²K. We confirm which applies to your job before you commit.
Do you need scaffolding to fit a rooflight?
Not always. Single-storey roofs can often be reached safely with ladders, a tower or edge protection. Higher roofs, steep pitches and large units usually need scaffold or a mobile platform, and heavy glass may need a crane. We assess access from your photos or at the survey, and any scaffold or lifting cost is shown as its own line on the written quote.
