Towns we list in Somerset

Somerset is part of our normal coverage in England. Fitting teams travel out to the property, so a town-centre terrace and a house down a farm track are treated alike, as long as a fitter can get the unit to the roof safely. Dates are offered according to fitter availability, and the cost of travel is already in your written quote.

What we do on the day

Glass lifted and laid into the frame by hand or with gear
Roof membrane checked where it meets the lantern frame
Caps, end closures and ridge trims fitted and sealed
Upstand size and tolerance — We check the kerb against the lantern maker's figures before the kit is opened.
Following the build order — We assemble lanterns in exactly the sequence the instructions give.

Rules that apply in England

Two sets of rules matter in England. Planning: a rooflight on a house is normally permitted development if it projects no more than 0.15 m and stays below the highest part of the roof, but flats, listed buildings and Article 4 areas need checking. Building regulations: new openings need approval for the structure and energy performance, and a replacement is a controlled fitting. We are not registered with a competent person scheme, so we notify replacements to building control with a building notice and put the council's fee on the quote.

Common questions in Somerset

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 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 remove and dispose of the old rooflight?

Yes. Taking out the old unit is part of any replacement job, and it leaves with the rest of the waste unless you ask to keep it. Old domes, glass and frames go through proper waste routes. If removal turns up a rotten kerb or damaged decking, we show you what we have found and agree the repair with you before going any further.
