Rooflight leak repairs in Ely

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 Ely 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.

Coverage in and around Ely

Jobs across CB6, CB7 and CB25 are part of our normal cover for Ely. 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 Newmarket and March are covered on the same terms, so a house on the edge of town is no harder to book than one in the centre.

On the day, we cover

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

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.

Do you need permission in Ely?

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 Ely

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.

Do you charge for a leak investigation in Ely?

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.
