Where our fitters travel
Looking at a property near Tyldesley but not quite in it? We work across M29, M46 and M38 and outwards to Atherton, Leigh and Walkden. 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 Tyldesley.
On the day, we cover
- Membrane splits at the upstand cut back and patched
- Rotten kerb sections replaced where the timber has gone soft
- Lifted flashing or tape removed and renewed
- Upstand height and condition — We measure the kerb and probe the timber for softness.
- Warranty and who fitted it — We ask who fitted the rooflight and when before working on it.
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 Tyldesley
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
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 Tyldesley
Do you charge for a leak investigation in Tyldesley?
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.
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.
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.
