Fit-only rooflight installation in Mid Glamorgan

Before any rooflight is fitted in Mid Glamorgan, three measurements get checked: the builder's opening, the external size of the unit, and the upstand height above the finished roof, or the batten and tile details on a pitched roof. Get those right and the rest of the job follows. We handle fit-only rooflight installation in every part of Mid Glamorgan, with 8 towns listed on the site and the countryside between them covered too.

Towns we list in Mid Glamorgan

From the larger towns to the smaller places in between, we take on rooflight fitting across Mid Glamorgan. 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 Wales, where they arise, are covered by arrangement, and we tell you that before quoting.

What's included

  • Opening and upstand measured against the maker's drawing, timber to timber
  • Upstand height, level and fall checked, and squareness confirmed across the diagonals
  • Internal reveal trimmed or lined, with the protective film removed at the end
  • Delivery damage and missing parts — We ask you to open the delivery and check it as soon as it arrives, not on fitting day.
  • Internal versus external size — We check whether your rooflight's quoted size is the hole size or the outer frame size.

Rules that apply in Wales

Welsh rules differ from England's in one important way: rooflights lose permitted development rights in conservation areas, National Parks, AONBs and World Heritage Sites. Elsewhere on a house, a rooflight that projects no more than 150 mm and stays below the highest part of the roof is usually fine. Building regulations still apply to new openings, replacements we fit go through a building notice because we are not scheme-registered, and the energy limit for rooflights is 2.2 W/m²K. A new Welsh Approved Document L takes effect on 4 March 2027.

Common questions in Mid Glamorgan

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.

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.

Do you offer trade rates for builders and roofers?

We carry out subcontract fitting for builders, roofers, extension companies and commercial contractors. Pricing is per job or per schedule of units, agreed in writing before we start. We can work to your programme, fit on your upstand or build our own, and leave the opening ready for the next trade. Send drawings or a unit schedule and we will come back with a trade quote.
