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.

Towns we list in Berkshire

From the larger towns to the smaller places in between, we take on rooflight fitting across Berkshire. The process is the same for a terrace, a farmhouse extension or an industrial unit: details first, written quote second, fitting day third. Remote and island addresses in England, where they arise, are covered by arrangement, and we tell you that before quoting.

Included in the work

Kerbs checked and packed, adapted or rebuilt where needed
Access, edge protection and fragile-roof covers planned before work starts
Unit schedule and handover notes for the building's records
Energy limits for non-domestic roofs — We check new units against the energy limits for non-domestic buildings.
Fragile roofs and rooflights — We treat every rooflight and the roof around it as fragile until we have checked it.

Rules that apply in England

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.

Common questions in Berkshire

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.

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.

Does commercial rooflight work need building control?

Usually. New openings, structural changes and smoke vents go through building control, and on buildings covered by fire safety law that means a full plans application rather than a building notice. We are not registered with a competent person scheme, so replacements we fit are notified to building control. We confirm the route and show any fee on the quote.
