Rooflight leak repairs in Swansea & Neath Port Talbot

Across Swansea & Neath Port Talbot we fit leaking rooflights for homeowners, builders, roofers and commercial clients. The trade side matters: an extension company with jobs running in several of the 5 towns we list does not want to coordinate a different fitter for each. We can take the rooflight element of every site, fitted to the maker's instructions and left ready for the next trade. Domestic customers get the same fitting standard, quoted in writing before work begins.

Towns we list in Swansea & Neath Port Talbot

From the larger towns to the smaller places in between, we take on rooflight fitting across Swansea & Neath Port Talbot. 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.

Included in the work

  • Failed sealant cut out, joints cleaned, dried and resealed
  • Controlled water test where it helps pin down the entry point
  • Lifted flashing or tape removed and renewed
  • Water lying against the kerb — We check whether rainwater sits against the upstand after it stops raining.
  • Upstand height and condition — We measure the kerb and probe the timber for softness.

Rules that apply in Wales

For a Welsh home, start with where the house is. In a conservation area, National Park, AONB or World Heritage Site, a rooflight needs planning permission; outside those, permitted development usually covers one that projects 150 mm or less. Side-facing roof windows within 10.5 m of a boundary must be obscure-glazed and fixed. New openings need building regulations approval, and replacements we fit are notified with a building notice, as we are not registered with a competent person scheme. We confirm all of this for your address.

Common questions in Swansea & Neath Port Talbot

Will resealing fix my leaking rooflight?

Sometimes. If the sealant has simply aged and the flashing, upstand and glass are sound, a careful reseal on a dry day can solve it. If the real problem is ponding water, a low upstand or a perished membrane, fresh sealant will only hide it for a while. We tell you which one you are dealing with before recommending any work, and quote the proper fix in writing.

Is it condensation or a leak?

Condensation tends to appear on cold mornings, on the inner face of the glass, and runs down the frame. A leak usually follows rain or wind from a particular direction and often stains the ceiling around the opening. Blocked condensation channels can make the two look alike. Photos and a note of when it happens help us narrow it down before the visit.

Do you charge for a leak investigation in Swansea & Neath Port Talbot?

Yes. Tracing a leak properly takes time on the roof, a close look at the frame and sometimes a water test, so the visit is charged. We confirm the price before you book, so there are no surprises. If a repair is needed beyond what can be done during the visit, it is quoted separately in writing and you decide whether to go ahead.
