Rooflight leak repairs in Newtownabbey

Misting between the panes means the seal on the glass unit has gone. No amount of wiping will clear it, but the frame may be perfectly sound. Where the maker's design allows, rooflight leak repairs in Newtownabbey can mean changing just the sealed unit rather than the whole rooflight. Other faults look similar from below: condensation on the inner face, or a slow leak at a perished seal. A charged diagnostic visit, priced before you book, tells you which one you have.

Coverage in and around Newtownabbey

Looking at a property near Newtownabbey but not quite in it? We work across BT37, BT36 and BT15 and outwards to Belfast, Carrickfergus and Castlereagh. Give us the full postcode when you get in touch, because access, parking and the route for a large unit all depend on the exact street. Those details shape the quote for any job around Newtownabbey.

What we do on the day

  • Failed sealant cut out, joints cleaned, dried and resealed
  • Rotten kerb sections replaced where the timber has gone soft
  • Outside inspection of glass, frame, sealant, flashing and roof covering
  • Leak or condensation — We work out whether the water is coming from outside or forming inside on cold glass.
  • Water lying against the kerb — We check whether rainwater sits against the upstand after it stops raining.

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.

Regulations for Newtownabbey properties

Northern Ireland has its own rules. Permitted development for rooflights on a house requires the unit to sit below the highest part of the roof, project no more than 15 cm where the slope faces a road, and stay at least half a metre from the ridge, eaves, party wall and verge. It doesn't apply in conservation areas or within the grounds of a listed building. For building control, structural roof alterations need an application, and rooflights must meet WER Band C or 1.6 W/m²K.

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 Newtownabbey

Do you charge for a leak investigation in Newtownabbey?

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.

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.
