Rooflight leak repairs in Wigan

Look at the roof after rain. If water sits in a puddle against one side of the rooflight, that ponding may be the real culprit, soaking into the joint where the kerb meets the membrane. Fixing it can mean adjusting the falls, raising the upstand or redressing the membrane, not just fresh sealant. We carry out rooflight leak repairs across Wigan by tracing the source first. The visit is charged, at a figure agreed before you book, and any further work is quoted in writing.

Areas around Wigan we cover

Distance is rarely the deciding factor. A roof in Hindley, 2 miles from Wigan, gets the same survey, the same written quote and the same fitting process as one in WN1, WN3 and WN5. What changes the price is the job itself: size of unit, roof type, access and lifting. Ashton in Makerfield, around 4 miles out, is treated the same way.

On the day, we cover

  • Membrane splits at the upstand cut back and patched
  • Lifted flashing or tape removed and renewed
  • Outside inspection of glass, frame, sealant, flashing and roof covering
  • Warranty and who fitted it — We ask who fitted the rooflight and when before working on it.
  • Upstand height and condition — We measure the kerb and probe the timber for softness.

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

England's rules in short: permitted development usually covers a rooflight on a house roof provided it doesn't stick out more than 0.15 m or rise above the ridge, though a listed building always needs consent and some streets have Article 4 directions. Building regulations apply to new openings, and replacements go through building control; as we are not registered with a competent person scheme, we use a building notice and show the fee on the quote. The energy limit for rooflights in existing homes is 2.2 W/m²K, and the 2026 Approved Document L, in force from 24 March 2027, keeps that figure.

Common questions in Wigan

Do you charge for a leak investigation in Wigan?

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.

Can you replace just the misted glass?

Often, yes. Misting between the panes means the sealed unit has failed, but the frame around it may be perfectly sound. Where the maker's design allows the glass to be changed, we measure the unit and fit a replacement, which costs less than a whole new rooflight. Where it does not, or the frame is also worn out, we explain why replacement is the better option.

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.
