Programme of works
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 control fees, where a job needs them, are shown as their own line.
Is your address covered?
Our fitters come to you. For Yate that covers BS37, BS36 and GL9, plus nearby Mangotsfield and Kingswood. We do not keep a yard or showroom in the area, and you do not need to visit one. The survey happens at your property or, for fit-only work, from the photos you send. Dates follow fitter availability, which we confirm when you accept the quote.
What we do on the day
- Unit schedule and handover notes for the building's records
- Roof survey of every unit, kerb and the fragile areas around them
- Access, edge protection and fragile-roof covers planned before work starts
- Working around occupied buildings — We plan noise, dust and access around the people using the building.
- Fire performance near boundaries — We check how close the rooflights are to the site boundary and to escape routes.
A typical installation day
Protection comes before tools. Floors, furniture and stairs get covered, and the ceiling below the opening is sheeted to catch dust. Up top, the fitters confirm the opening is square and the upstand or flashing suits what the maker specifies. Fixing follows, then weather-sealing into the membrane, felt or tiles. Only once the roof is tight do they turn to the internal reveal. Time on site for a commercial rooflight: about a day per unit, longer on big roofs, weather permitting.
Planning, building control and Yate
On commercial buildings in England, new rooflights and changes to roof structure go through building control, and replacements in non-dwellings also need building control involvement unless fitted by a scheme-registered installer, which we are not; load-bearing or structural glass always goes through building control. Fire rules matter near boundaries and over escape routes, and smoke vents must be certified to BS EN 12101-2. We confirm the route and the paperwork for your building before work starts.
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, BS37 or nearby, confirms travel.
Common questions in Yate
What if my roof opening is the wrong size for the commercial rooflight?
We find out before the fitting day, not on it. If the opening is slightly out, it can usually be adjusted by trimming or by packing out the upstand. If it is a long way off, the choice is between altering the opening and changing the unit. Bear in mind that rooflights are often sold by builder's opening size rather than external size, so check which one your measurement refers to.
Will my new commercial rooflight leak?
A correctly fitted unit should not. Leaks usually trace back to the detail around the frame: an upstand that is too low, a membrane or flashing that is not dressed properly, sealant applied to a damp surface, or water ponding against the kerb. We fit to the maker's instructions and check each of those points. The fitting carries a written workmanship guarantee, with its terms set out on your quote.
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.
Send a few photos and your BS37 postcode, and we will put together a written quote for the job.
