Rooflight leak repairs in Hitchin

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 Hitchin 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 Hitchin we cover

If you also own a property or a business unit in Letchworth Garden City, Stevenage or Luton, 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 SG5, SG4 and SG6 sit comfortably within that pattern.

On the day, we cover

  • Outside inspection of glass, frame, sealant, flashing and roof covering
  • Membrane splits at the upstand cut back and patched
  • Failed sealant cut out, joints cleaned, dried and resealed
  • Leak or condensation — We work out whether the water is coming from outside or forming inside on cold glass.
  • Water lying against the kerb — We check whether rainwater sits against the upstand after it stops raining.

How a repair visit goes

Expect the visit to be mostly looking and testing. Dust sheets go down below the rooflight. The fitter checks seals and glass from inside, then gets up on the roof by ladder or tower. Minor jobs such as clearing a blocked drainage channel can often be dealt with there and then. Bigger work, like new flashing or a replacement sealed unit, is measured up and priced in writing afterwards.

Planning, building control and Hitchin

Replacing a rooflight in an English home is a controlled fitting: it has to be self-certified by a scheme-registered installer or notified to building control. We are not registered with a competent person scheme, so replacements we fit are notified with a building notice, and the new unit has to meet current energy limits. Adding a new one usually means a building regulations application, because joists or rafters are trimmed. On the planning side, most house rooflights are permitted development if they project 0.15 m or less; on a side slope the glass must be obscured and fixed unless the opening part is over 1.7 m above the floor.

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, SG5 or similar, and how the roof is reached.

Common questions in Hitchin

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.

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.

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.
