Rooflight installers in Gorseinon

Rooflight fitting in Gorseinon, Swansea & Neath Port Talbot, covers more ground than most people expect. Some jobs are fit-only: you have bought a unit and need it installed properly. Some are replacements for old domes and misted glass. Others mean cutting a new opening into a flat or pitched roof, trimming joists or rafters, and building an upstand. Then there are roof lanterns, pitched roof windows, sun tunnels and access hatches, plus trade work for builders and roofers. Each service has its own page below, with guide prices and what the job involves.

Commercial & trade

Specialist fitting or a general builder

The joint between the rooflight and the roof covering is where most leaks start. On a flat roof that means turning the membrane up the kerb and terminating it properly under the frame. On a pitched roof it means the right flashing kit, lapped correctly with the tiles or slates. These details are fiddly and easy to rush on a busy build. Giving them to someone focused on fitting the rooflight, rather than treating it as one task among dozens, cuts the chance of a callback.

Is your Gorseinon address covered?

Our fitters cover all of Gorseinon, including SA4, SA5 and SA2, and travel on to Llanelli, Swansea and Clydach on the same basis. Nobody needs to visit us, because we come to the property for surveys and fitting. Dates are offered according to fitter availability, and travel is part of the written quote rather than an extra.

Planning and building rules in Wales

Wales sets energy limits of 2.2 W/m²K for rooflights and 1.4 W/m²K for roof windows, and new rooflight openings generally need building regulations approval. Replacement units are controlled fittings; we are not registered with a competent person scheme, so ours are covered by a building notice to the council. Planning permission is needed for rooflights in conservation areas, National Parks, AONBs and World Heritage Sites. We check which applies and include the fee in your quote.

Questions about rooflight fitting in Gorseinon

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.

Will my new 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 is included in the price?

The written quote lists it line by line. Typically that covers fitting labour, fixings, sealants, membrane or flashing materials, any upstand work, internal finishing if agreed, and taking away the waste. For supply and fit, the unit itself is included too. Scaffold, lifting gear and any third-party fees, where needed, are shown separately so you can see what each part of the job costs.

Can you fit the rooflight I bought online?

Yes, fit-only is one of our core services. Send the product link or spec, photos of the roof and rough sizes, and we can usually price it from those. Before fitting we check the delivery for damage, which should be reported to the seller, plus the size against the builder's opening and the upstand height. The product warranty stays with the maker or seller, and our guarantee covers the fitting.
