Guide ranges for supply & fit. 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.
Coverage by arrangement
Lerwick is covered by arrangement. Tell us the address and we will confirm travel, dates and any ferry or accommodation costs before quoting. Many island and remote jobs can be priced from photos first, so nobody travels until the scope is clear.
Fit-only or supply and fit
Which works out better, buying your own or letting us supply? It depends on what you value. Buying your own gives you control of the product and what you pay for it. Letting us supply puts the whole job, unit and fitting, under one written quote. On a customer-supplied unit we still measure it against the opening, look at the upstand, and inspect the condition it arrived in. Warranty on the product sits with whoever sold it, while the fitting carries our own guarantee.
What we do on the day
- Upstand checked or built to the maker's internal and external sizes
- Reveal lined and trimmed inside, with the glass left clean
- Unit bedded on the specified sealant or tape and screw-fixed
- Solar gain on south-facing roofs — We ask which way the roof faces and how the room is used before suggesting glass.
- Weight of large panes — We check the weight of the unit against how we will get it onto the roof.
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 flat 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.
Planning, building warrants and Lerwick
In Scotland a new rooflight needs a building warrant before work starts. A like-for-like replacement including the frame is exempt from a warrant but must meet current standards, so the glazing has to reach 1.6 W/m²K or better. For planning, rooflights on houses outside conservation areas can often go ahead under permitted development, but it is worth confirming with the planning authority.
Before you get in touch
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 ZE1 and we will come back with a quote or a survey date.
Common questions in Lerwick
Do you make good inside after fitting?
Yes, where the quote includes it. Internal finishing usually means lining the reveal with plasterboard, taping or skimming, and fitting trim where it meets the ceiling. Some people prefer their own plasterer or decorator to finish off, which is fine. The written quote spells out exactly where our work stops, so nobody is left guessing about who does what once the unit is in.
Can you replace an old dome without redoing the whole roof?
Usually, yes. If the existing kerb is sound, level and tall enough, a new unit can often sit on it with a fresh seal to the roof covering. If the kerb is rotten or too low, we rebuild it and patch the covering around it rather than stripping the whole roof. This is checked at the survey and included in the written quote, so you know the full scope first.
Will my new flat 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.
