Rooflight leak repairs in Bexhill-on-Sea

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 Bexhill-on-Sea 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.

Where our fitters travel

If you also own a property or a business unit in Hastings, Hailsham or Eastbourne, that is no problem. We can survey and quote both, and where it suits, line the fitting days up together. Every address is reached by fitters travelling to it from their current jobs, and TN40, TN39 and TN38 sit comfortably within that pattern.

What the job includes

  • Controlled water test where it helps pin down the entry point
  • Rotten kerb sections replaced where the timber has gone soft
  • Outside inspection of glass, frame, sealant, flashing and roof covering
  • Age of the rooflight — We weigh the age and condition of the unit before recommending a repair.
  • Water lying against the kerb — We check whether rainwater sits against the upstand after it stops raining.

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, building control and Bexhill-on-Sea

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.

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, TN40 or similar, and how the roof is reached.

Common questions in Bexhill-on-Sea

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 Bexhill-on-Sea?

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.
