Phased replacement across a building, priced from a survey
Guide ranges for supply & fit, per unit; site set-up priced separately. Your price is fixed in a written quote after we have seen photos or surveyed. Scaffold, access towers or a crane are priced separately if the job needs them, and building warrant fees, where a job needs them, are shown as their own line.
Is your address covered?
If you also own a property or a business unit in Dumbarton, Helensburgh or Erskine, that is no problem. We can survey and quote both, and where it suits, line the fitting days up together. Every address is reached by fitters travelling to it from their current jobs, and G82, G83 and G60 sit comfortably within that pattern.
On the day, we cover
- Old units removed, with waste taken off site
- Roof survey of every unit, kerb and the fragile areas around them
- New units fitted, sealed and weathered into the roof covering
- Working around occupied buildings — We plan noise, dust and access around the people using the building.
- Glass or polycarbonate — We compare glass and polycarbonate units against the roof, use and budget.
From arrival to clean-up
On the day, you need to be in at the start and at the end. In between, the fitters get on with it. They will want the room below cleared where possible, a parking spot if you have one, and somewhere to set the unit down safely. After checking the opening and the upstand or flashing, they fix a commercial rooflight, seal it and finish the inside. Packaging and any old unit leave with them unless the quote says otherwise.
Regulations for Vale of Leven properties
On non-domestic buildings and blocks of flats in Scotland, new rooflights and roof alterations need a building warrant, and the Technical Handbooks set energy and fire requirements for the glazing. Smoke vents must be certified products with controls commissioned by a specialist. We confirm the warrant route for your building.
Getting a price from photos
Each detail you send takes a question off our list. Photos inside and out show the opening and the ceiling. Rough measurements tell us the unit size. The roof covering tells us how it will be sealed in. Access notes tell us whether a tower or scaffold is needed. A product link, if you have one, lets us check it against the opening. Your postcode, G82 or nearby, confirms travel.
Common questions in Vale of Leven
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.
How long does fitting take?
Fitting a commercial rooflight into an existing, correctly sized opening is often a day's work. New openings take longer, because joists or rafters need trimming, an upstand or flashing has to be built or fitted, and the inside needs finishing. Large units that need lifting gear, and days lost to rain, can stretch things further. Your written quote gives a realistic estimate for your roof.
What is included in the price?
The written quote lists it line by line. Typically that covers fitting labour, fixings, sealants, membrane or flashing materials, any upstand work, internal finishing if agreed, and taking away the waste. For supply and fit, the unit itself is included too. Scaffold, lifting gear and any third-party fees, where needed, are shown separately so you can see what each part of the job costs.
