Rooflight leak repairs in Perth

Leaks and misting around a rooflight tend to come from a short list of causes. Sealant that has cracked or pulled away. Flashing or membrane that has perished at the edges. Condensation channels blocked with dirt, so water backs up inside the frame. Ponding water lying against the kerb because the roof falls the wrong way. Or a sealed glass unit that has failed and misted between the panes. Our rooflight leak repairs visits in Perth work through these in turn, with the visit priced before booking.

Where our fitters travel

Distance is rarely the deciding factor. A roof in Glenrothes, 17 miles from Perth, gets the same survey, the same written quote and the same fitting process as one in PH2, PH1 and PH14. What changes the price is the job itself: size of unit, roof type, access and lifting. Dundee, around 18 miles out, is treated the same way.

What the job includes

  • Lifted flashing or tape removed and renewed
  • Failed sealant cut out, joints cleaned, dried and resealed
  • Outside inspection of glass, frame, sealant, flashing and roof covering
  • Warranty and who fitted it — We ask who fitted the rooflight and when before working on it.
  • Age of the rooflight — We weigh the age and condition of the unit before recommending a repair.

How a repair visit goes

A repair visit starts outside. The fitter looks at the roof around the unit for ponding, split membrane, loose flashing and failed sealant, then moves inside to check stains, the frame and the condensation channels. Where it helps, a controlled water test narrows down the entry point. Before leaving, they explain what they found and whether a small fix can be done within the agreed visit, or needs a separate written quote.

Do you need permission in Perth?

For Scottish homes: building warrant for new rooflight openings; no warrant for replacing a rooflight complete with its frame, provided it meets the standards, including 1.6 W/m²K; planning permission in conservation areas and listed building consent for listed properties. Outside those, permitted development usually covers house rooflights, but the planning authority has the final word, so we check before you commit.

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 Perth

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.

Do you charge for a leak investigation in Perth?

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.

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.
