Rooflight leak repairs in Didcot

A repair visit is charged, and you know the price before you book it. Here is why: tracing a leak properly takes time on the roof, sometimes a water test, and a careful look inside the frame. Guessing is cheaper on the day and dearer later. For rooflight leak repairs in Didcot we diagnose first, explain what we found in plain terms, and then quote the fix. Typical outcomes are resealing, new flashing, cleared drainage channels, or a replacement glass unit.

Is your address covered?

Didcot and the districts around it, OX11, OX14 and OX10, all sit inside our working area. So does the ground between Didcot and Abingdon (5 miles), and on towards Cowley (9 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.

Included in the work

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

How a repair visit goes

A repair visit starts outside. The fitter looks at the roof around the unit for ponding, split membrane, loose flashing and failed sealant, then moves inside to check stains, the frame and the condensation channels. Where it helps, a controlled water test narrows down the entry point. Before leaving, they explain what they found and whether a small fix can be done within the agreed visit, or needs a separate written quote.

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

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, OX11 or similar, and how the roof is reached.

Common questions in Didcot

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.
