Rooflight leak repairs in Glasgow & Dunbartonshire

Rooflight fitting in Glasgow & Dunbartonshire is planned around dry spells, not just calendar dates. That matters more than people think: membranes and sealants need a dry surface, and a roof should not be left open in poor weather. So when we offer a date for rooflight leak repairs, it comes with a sensible fallback. We take jobs across all 36 postcode districts in Glasgow & Dunbartonshire, and the written quote sets out what is included before you commit.

Builders and roofers working in Glasgow & Dunbartonshire 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

  • Outside inspection of glass, frame, sealant, flashing and roof covering
  • Inside check of stains, frame drainage channels and the reveal
  • Controlled water test where it helps pin down the entry point
  • Water lying against the kerb — We check whether rainwater sits against the upstand after it stops raining.
  • Warranty and who fitted it — We ask who fitted the rooflight and when before working on it.

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 Glasgow & Dunbartonshire

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.

Can you replace just the misted glass?

Often, yes. Misting between the panes means the sealed unit has failed, but the frame around it may be perfectly sound. Where the maker's design allows the glass to be changed, we measure the unit and fit a replacement, which costs less than a whole new rooflight. Where it does not, or the frame is also worn out, we explain why replacement is the better option.
