Rooflight leak repairs in Cheltenham

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 Cheltenham 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?

Distance is rarely the deciding factor. A roof in Tewkesbury, 7 miles from Cheltenham, gets the same survey, the same written quote and the same fitting process as one in GL50, GL51 and GL52. What changes the price is the job itself: size of unit, roof type, access and lifting. Gloucester, around 7 miles out, is treated the same way.

On the day, we cover

  • Outside inspection of glass, frame, sealant, flashing and roof covering
  • Rotten kerb sections replaced where the timber has gone soft
  • Lifted flashing or tape removed and renewed
  • 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

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 and building rules in England

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

Before booking a visit, send what you can: a photo of the ceiling or reveal where water shows, a photo of the rooflight from outside, the roof covering if you know it, and whether it is one rooflight or several. We use that to price the visit and to bring the right materials.

Common questions in Cheltenham

Why is my rooflight leaking?

The usual causes are sealant that has cracked or pulled away, flashing or membrane that has perished at the edges, condensation channels blocked with dirt, water ponding against the kerb, or a seal failing on the glass unit. Sometimes the water is coming in elsewhere and running along to the rooflight. A diagnostic visit finds the real source before anyone starts applying sealant.

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.
