Rooflight leak repairs in Glossop

Water dripping under a rooflight does not always mean the rooflight itself has failed. It might be the sealant, the flashing, the upstand, or water sitting on the roof against the kerb. That is why a repair in Glossop starts with finding the cause rather than reaching for a sealant gun. The investigation visit is charged, and we confirm that price before you book it. Once we know what is wrong, you get a written quote for the repair, or honest advice that replacement makes more sense.

Areas around Glossop we cover

Jobs across SK13, SK22 and SK23 are part of our normal cover for Glossop. We are not an office on the high street. Our fitting teams come out to the property from wherever they are working that week. Neighbouring places such as Stalybridge and Hyde are covered on the same terms, so a house on the edge of town is no harder to book than one in the centre.

What the job includes

  • Outside inspection of glass, frame, sealant, flashing and roof covering
  • Rotten kerb sections replaced where the timber has gone soft
  • Controlled water test where it helps pin down the entry point
  • Upstand height and condition — We measure the kerb and probe the timber for softness.
  • Warranty and who fitted it — We ask who fitted the rooflight and when before working on it.

How a repair visit goes

On arrival we agree access and protect the floor. Then a methodical check: glass for misting or cracks, seals for gaps, the frame for movement, the upstand and roof covering for splits or water lying against the kerb. If the cause is obvious and minor, it can usually be sorted as part of the visit. If not, you have the evidence and a priced repair plan, and the choice is yours.

Planning and building rules in England

In England, a new rooflight opening generally needs building regulations approval because the roof structure is altered and the glazing must meet energy rules: 2.2 W/m²K for a rooflight in an existing home, or 1.4 W/m²K (or WER Band B) for a roof window. Planning is often not needed on a house: permitted development covers rooflights that stand no more than 0.15 m proud of the roof slope and sit below the highest part of the roof. Flats, listed buildings and areas with an Article 4 direction are different, so we check your address first.

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 Glossop

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.
