Commercial rooflight installation in Fort William

Plenty of rooflight trouble starts with a tape measure. Units are often sold by the builder's opening, meaning the hole in the roof, rather than the overall external size, and confusing the two leaves you with a frame that does not suit the opening. Before we fit any commercial rooflight in Fort William, we measure the opening, the upstand or kerb where there is one, and the finished roof level, then compare them with the maker's drawing. If something is out, you hear about it before the fitting day rather than on it. That single check keeps most jobs like this on track.

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.

Coverage by arrangement

Jobs in Fort William, including PH33, PH50 and PH49, are taken on by arrangement rather than as routine cover. Send the postcode, photos and sizes; we confirm whether and when a fitting team can travel, and the travel cost is set out in the written quote before you agree to anything.

What the job includes

  • Kerbs checked and packed, adapted or rebuilt where needed
  • Old units removed, with waste taken off site
  • 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.
  • Energy limits for non-domestic roofs — We check new units against the energy limits for non-domestic buildings.

What happens on the day

Arrive and agree the plan. Sheet the floor and furniture. Set up the ladder, tower or scaffold. Check the opening, the upstand or flashing, and the unit against the paperwork. Fix and pack a commercial rooflight level. Seal it into the roof. Line the reveal or fit the ceiling trim. Clean the glass, clear the waste, and talk you through it. That is the shape of most fitting days, and for this type of job it usually takes about a day per unit, longer on big roofs.

Regulations for Fort William properties

Rooflight work on non-domestic buildings and blocks of flats in Scotland is covered by the domestic or non-domestic Technical Handbook, depending on the building: a building warrant for new openings, energy limits for the glazing and fire checks near boundaries. Replacements complete with frames have their own rules. We set out what applies before work starts.

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, PH33 or nearby, confirms travel.

Common questions in Fort William

How does payment work?

Payment terms are set out on your written quote before you accept it. Depending on the job, that may mean a deposit, stage payments for larger work, or payment on completion. The contract is with S&K Property Investments and Improvement Ltd, part of the S&K Group. Nothing is added without your agreement: if something unexpected comes up, we discuss it and agree any change before carrying on.

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.

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.
