Rooflight leak repairs in Uxbridge

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 Uxbridge by tracing the source first. The visit is charged, at a figure agreed before you book, and any further work is quoted in writing.

Coverage in and around Uxbridge

Uxbridge and the districts around it, UB8, UB10 and UB11, all sit inside our working area. So does the ground between Uxbridge and Ruislip (3 miles), and on towards Hayes (3 miles). When a fitting team is booked, their travel is already in the quoted price, so it does not turn up as a surprise line on the final bill.

What the job includes

  • Controlled water test where it helps pin down the entry point
  • Failed sealant cut out, joints cleaned, dried and resealed
  • Outside inspection of glass, frame, sealant, flashing and roof covering
  • Upstand height and condition — We measure the kerb and probe the timber for softness.
  • Age of the rooflight — We weigh the age and condition of the unit before recommending a repair.

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

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, UB8 or similar, and how the roof is reached.

Common questions in Uxbridge

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 Uxbridge?

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.

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.
