Guide ranges for supply & fit; building control notice fee extra in England and Wales. Your price is fixed in a written quote after we have seen photos or surveyed. Scaffold, access towers or a crane are priced separately if the job needs them, and building control fees, where a job needs them, are shown as their own line.
Fitting across Altrincham and nearby
Distance is rarely the deciding factor. A roof in Hale, 1 mile from Altrincham, gets the same survey, the same written quote and the same fitting process as one in WA14, WA15 and M33. What changes the price is the job itself: size of unit, roof type, access and lifting. Sale, around 3 miles out, is treated the same way.
Buying your own, or letting us supply
There are two ways to do this. Supply and fit means we source a replacement rooflight that suits your roof and install it, so one company answers for both the product choice and the fitting. Fit-only means you buy the unit and we install it. With fit-only, the product warranty stays with the maker or seller, and our written guarantee covers the fitting work. Both routes get the same checks on the opening, the upstand and the maker's instructions before anything is fixed.
What we do on the day
- Old rooflight or dome unscrewed, lifted out and taken away for disposal
- Building notice given to the council in England and Wales, with its fee on the quote
- New unit bedded, fixed and sealed exactly as its maker shows
- Inside finishes — We check the condition of the plaster and trim around the opening from inside.
- Leaks that are not the rooflight — We look at the roof around the unit before blaming the rooflight.
Fitting your replacement rooflight, step by step
Where a job takes one day, the split is usually structural work first and finishing second. Early on, the fitters cut or prepare the opening, trim where needed and prepare the upstand or flashing. Then a replacement rooflight is lifted in, fixed and made weathertight so the roof is sound before anyone moves inside. Plasterboard, trim and filler for the reveal come after. Each evening the work area is swept, and at the end the glass is cleaned and the team talks you through what was done.
Regulations for Altrincham properties
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 for a quick quote
A fast quote needs five things: a photo of the roof from outside, one from the room below, rough sizes of the opening or the space, the roof covering (felt, single-ply, fibreglass, tiles, slate or metal), and a note on access. If you have already bought the unit, add the product link or spec sheet. And give us the postcode, WA14 or a neighbouring district.
Common questions in Altrincham
How long does fitting take?
Fitting a replacement rooflight into an existing, correctly sized opening is often a day's work. New openings take longer, because joists or rafters need trimming, an upstand or flashing has to be built or fitted, and the inside needs finishing. Large units that need lifting gear, and days lost to rain, can stretch things further. Your written quote gives a realistic estimate for your roof.
Do you cover Altrincham?
Yes. Fitters travel to addresses in Altrincham and the surrounding districts, including WA14. We do not run an office there; the survey and the fitting happen at your property. A few island and remote postcodes are covered by arrangement; if yours is one, we confirm travel and dates before quoting.
Do you need scaffolding to fit a rooflight?
Not always. Single-storey roofs can often be reached safely with ladders, a tower or edge protection. Higher roofs, steep pitches and large units usually need scaffold or a mobile platform, and heavy glass may need a crane. We assess access from your photos or at the survey, and any scaffold or lifting cost is shown as its own line on the written quote.
Got a unit waiting to go in, or need one sourced? Either way, start with your Altrincham address and a couple of photos.
