Guide ranges. The first visit is charged and priced before booking; any repair is priced in writing before work starts. Scaffold, access towers or a crane are priced separately if the job needs them, and building warrant fees, where a job needs them, are shown as their own line.
Is your address covered?
Distance is rarely the deciding factor. A roof in Barrhead, 3 miles from Newton Mearns, gets the same survey, the same written quote and the same fitting process as one in G77, G76 and G46. What changes the price is the job itself: size of unit, roof type, access and lifting. Paisley, around 6 miles out, is treated the same way.
On the day, we cover
- Outside inspection of glass, frame, sealant, flashing and roof covering
- Lifted flashing or tape removed and renewed
- Failed sealant cut out, joints cleaned, dried and resealed
- Age of the rooflight — We weigh the age and condition of the unit before recommending a repair.
- Upstand height and condition — We measure the kerb and probe the timber for softness.
How a repair visit goes
Most of the effort on a repair visit goes into finding the cause. We start with your account of when it leaks: heavy rain, wind from one direction, or cold mornings, which points towards condensation. That shapes where we look first. Findings are photographed so you can see them for yourself. You then get a clear explanation and, where needed, a written repair quote, fixed before anything further is booked.
Planning and building rules in Scotland
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
Photos help us price the visit. Send one of the stain or drip inside, one of the rooflight from outside if you can reach a safe viewpoint, and a note of when it leaks: in heavy rain, in wind, or all the time. Add the postcode, G77 or similar, and how the roof is reached.
Common questions in Newton Mearns
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.
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.
