Rooflight leak repairs in Hawarden

Tell us what you are seeing: drips, stains on the ceiling, misting, a draught, or a rooflight that no longer closes tight. Photos help. From that we arrange a diagnostic visit in Hawarden, with its cost agreed before booking. On site we check the sealant, the flashing or membrane upturn, the condensation channels and the glass. Then you get a straight answer and, if a repair is worth doing, a written quote for the rooflight leak repairs.

Covering CH5 and neighbouring districts

Covering Hawarden means covering the people who live and work there, not a single postcode. We take on domestic and commercial jobs in CH5, CH4 and CH7, and are happy to quote further out in Deeside and Buckley. If your address sits between towns, tell us and we will confirm whether it falls in our normal area or needs travel set out separately on the quote.

What the job includes

  • Inside check of stains, frame drainage channels and the reveal
  • Failed sealant cut out, joints cleaned, dried and resealed
  • Rotten kerb sections replaced where the timber has gone soft
  • Warranty and who fitted it — We ask who fitted the rooflight and when before working on it.
  • Leak or condensation — We work out whether the water is coming from outside or forming inside on cold glass.

How a repair visit goes

On arrival we agree access and protect the floor. Then a methodical check: glass for misting or cracks, seals for gaps, the frame for movement, the upstand and roof covering for splits or water lying against the kerb. If the cause is obvious and minor, it can usually be sorted as part of the visit. If not, you have the evidence and a priced repair plan, and the choice is yours.

Do you need permission in Hawarden?

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.

What to send us

Tell us where the water appears, how long it has been happening and what the weather was doing when it started. A couple of photos from inside and outside, plus the postcode, let us price the visit before you book and plan what the fitter brings.

Common questions in Hawarden

Why is my rooflight leaking?

The usual causes are sealant that has cracked or pulled away, flashing or membrane that has perished at the edges, condensation channels blocked with dirt, water ponding against the kerb, or a seal failing on the glass unit. Sometimes the water is coming in elsewhere and running along to the rooflight. A diagnostic visit finds the real source before anyone starts applying sealant.

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.
