Commercial rooflight installation in Frome

Our guide price for commercial rooflight installation starts from £1,095, and the real figure for your roof in Frome depends on a handful of things: the size and type of commercial rooflight, whether the opening exists already, the roof covering, and how easy access is. We fix the price in a written quote before work begins. Nothing gets added on the day without your say-so. For a rough idea first, photos and a couple of measurements are enough to go on, and we cover all of Somerset.

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.

Areas around Frome we cover

Distance is rarely the deciding factor. A roof in Westbury, 6 miles from Frome, gets the same survey, the same written quote and the same fitting process as one in BA11, BA3 and BA2. What changes the price is the job itself: size of unit, roof type, access and lifting. Warminster, around 6 miles out, is treated the same way.

On the day, we cover

  • Old units removed, with waste taken off site
  • Unit schedule and handover notes for the building's records
  • 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.
  • Fragile roofs and rooflights — We treat every rooflight and the roof around it as fragile until we have checked it.

How a fitting day runs

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 Frome properties

For non-domestic roofs in England, expect building control involvement for new openings, energy limits of 2.2 W/m²K for rooflights, and fire checks where rooflights sit near a boundary or above an escape route. Smoke ventilation rooflights must be certified products, with controls commissioned by a specialist. We set out what applies to your building on the quote.

What to send for a quick quote

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, BA11 or nearby, confirms travel.

Common questions in Frome

Can you fit a rooflight in winter or when it is raining?

Yes, within limits. Cold is less of a problem than wet, because membranes, primers and sealants need a dry surface to bond. We plan fitting days around the forecast and may move a date if heavy rain is due. If the roof has to be opened up, it is not left overnight without a temporary weather seal, so the room below stays dry while the work is finished.

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.

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.
