Rooflight leak repairs in Nantwich

Tell us what you are seeing: drips, stains on the ceiling, misting, a draught, or a rooflight that no longer closes tight. Photos help. From that we arrange a diagnostic visit in Nantwich, with its cost agreed before booking. On site we check the sealant, the flashing or membrane upturn, the condensation channels and the glass. Then you get a straight answer and, if a repair is worth doing, a written quote for the rooflight leak repairs.

Fitting across Nantwich and nearby

Looking at a property near Nantwich but not quite in it? We work across CW5, CW2 and CW1 and outwards to Crewe, Sandbach and Winsford. Give us the full postcode when you get in touch, because access, parking and the route for a large unit all depend on the exact street. Those details shape the quote for any job around Nantwich.

Included in the work

  • Controlled water test where it helps pin down the entry point
  • Membrane splits at the upstand cut back and patched
  • Inside check of stains, frame drainage channels and the reveal
  • Age of the rooflight — We weigh the age and condition of the unit before recommending a repair.
  • 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 Nantwich?

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

Tell us where the water appears, how long it has been happening and what the weather was doing when it started. A couple of photos from inside and outside, plus the postcode, let us price the visit before you book and plan what the fitter brings.

Common questions in Nantwich

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.

Do you charge for a leak investigation in Nantwich?

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.
