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 warrant fees, where a job needs them, are shown as their own line.
Fitting across Grangemouth and nearby
Jobs across FK3, FK2 and FK1 are part of our normal cover for Grangemouth. We are not an office on the high street. Our fitting teams come out to the property from wherever they are working that week. Neighbouring places such as Falkirk and Alloa are covered on the same terms, so a house on the edge of town is no harder to book than one in the centre.
What the job includes
- Unit schedule and handover notes for the building's records
- New units fitted, sealed and weathered into the roof covering
- Access, edge protection and fragile-roof covers planned before work starts
- Energy limits for non-domestic roofs — We check new units against the energy limits for non-domestic buildings.
- Fire performance near boundaries — We check how close the rooflights are to the site boundary and to escape routes.
A typical installation 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 commercial 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 Grangemouth 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
What we cannot see, we have to guess, and guesses make quotes wider. So the more you send, the tighter the price. Useful: shots from the roof or garden, shots from the room underneath, a rough width and length, the roof finish, any access problems, and the product page if you have already ordered. Add the property postcode around FK3 and we will come back with a quote or a survey date.
Common questions in Grangemouth
What upstand height and roof pitch does commercial rooflight fitting need?
It depends on the product. Manufacturers usually specify a minimum upstand height above the finished roof surface, and a minimum pitch on the glass so rain runs off. We follow the maker's figures for your unit rather than a rule of thumb. If your existing kerb or roof falls short, we explain the options, such as raising the upstand or choosing a unit with built-in pitch.
Do commercial rooflights need planning permission?
Like-for-like replacements on commercial buildings rarely need planning permission. New or larger rooflights on non-domestic buildings and blocks of flats usually need checking with the planning authority, because householder permitted development rights don't apply. We tell you what we know about your building and point you to the right team.
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.
