Rooflight leak repairs in Stranraer

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 Stranraer 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 Stranraer

Stranraer and the districts around it, DG9, all sit inside our working area. So does the ground between Stranraer and Ayr (42 miles), and on towards Irvine (52 miles). When a fitting team is booked, their travel is already in the quoted price, so it does not turn up as a surprise line on the final bill.

What the job includes

  • Lifted flashing or tape removed and renewed
  • Outside inspection of glass, frame, sealant, flashing and roof covering
  • Inside check of stains, frame drainage channels and the reveal
  • Leak or condensation — We work out whether the water is coming from outside or forming inside on cold glass.
  • Warranty and who fitted it — We ask who fitted the rooflight and when before working on it.

How a repair visit goes

Expect the visit to be mostly looking and testing. Dust sheets go down below the rooflight. The fitter checks seals and glass from inside, then gets up on the roof by ladder or tower. Minor jobs such as clearing a blocked drainage channel can often be dealt with there and then. Bigger work, like new flashing or a replacement sealed unit, is measured up and priced in writing afterwards.

Do you need permission in Stranraer?

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.

What to send us

Before booking a visit, send what you can: a photo of the ceiling or reveal where water shows, a photo of the rooflight from outside, the roof covering if you know it, and whether it is one rooflight or several. We use that to price the visit and to bring the right materials.

Common questions in Stranraer

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.

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.

Is it condensation or a leak?

Condensation tends to appear on cold mornings, on the inner face of the glass, and runs down the frame. A leak usually follows rain or wind from a particular direction and often stains the ceiling around the opening. Blocked condensation channels can make the two look alike. Photos and a note of when it happens help us narrow it down before the visit.
