Rooflight leak repairs in Dumfries & Galloway

A good share of rooflight leak repairs in Dumfries & Galloway is replacement work. Older units go brittle or discoloured, sealed glass mists, and seals give up after years of sun and frost. Swapping the unit is often possible on the existing kerb, provided that kerb is sound, level and tall enough above the finished roof. Where it is not, we rebuild it. We cover the whole of Dumfries & Galloway, across 15 postcode districts, with fitters travelling to each address.

Towns we list in Dumfries & Galloway

Builders and roofers working in Dumfries & Galloway can use us for the rooflight element of a job, wherever the site is in Scotland. Homeowners can book us directly.

What we do on the day

  • Membrane splits at the upstand cut back and patched
  • Inside check of stains, frame drainage channels and the reveal
  • Rotten kerb sections replaced where the timber has gone soft
  • Water lying against the kerb — We check whether rainwater sits against the upstand after it stops raining.
  • Leak or condensation — We work out whether the water is coming from outside or forming inside on cold glass.

Rules that apply in Scotland

If you live in Scotland, the key question is whether the job is new or a replacement. A new rooflight needs a building warrant. Swapping an old rooflight for a new one, frame included, doesn't, as long as the new unit meets the standards: the energy figure for new or replacement rooflights in alterations is 1.6 W/m²K. Conservation areas have no householder permitted development rights for roof alterations, and listed buildings need listed building consent.

Common questions in Dumfries & Galloway

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.

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.

Should I repair or replace my old leaking rooflight?

It depends on the age and condition of the unit and what has failed. A single perished seal or a blocked channel is worth repairing. A brittle, discoloured dome, a rotten kerb, or several faults at once usually make replacement the better value. After the diagnostic visit we set out both options with prices, so you can decide with the full picture in front of you.
