Loft conversion roof windows in Altrincham

Builders and extension firms in Altrincham often want the rooflight stage of a project handled by a specialist fitting team. We step in once the roof deck or battens are ready, fit a loft roof window on your upstand or ours, detail it into the membrane or tiles, and leave the opening ready for the plasterer. Homeowners get exactly the same service directly. In each case the job is quoted in writing first, with any access or lifting needs spelt out. Jobs around WA14 and the neighbouring districts are welcome.

Areas around Altrincham we cover

Covering Altrincham means covering the people who live and work there, not a single postcode. We take on domestic and commercial jobs in WA14, WA15 and M33, and are happy to quote further out in Hale and Sale. If your address sits between towns, tell us and we will confirm whether it falls in our normal area or needs travel set out separately on the quote.

Fit-only or supply and fit

Supply and fit tends to suit people who would rather not pick a unit from a catalogue. We look at the roof, the opening and how you use the room, then put a loft roof window on the quote that fits all three. Fit-only suits people who already know what they want, or have one on site. We are happy with either. The difference is who stands behind what: on fit-only, the maker or retailer covers the product, and our workmanship guarantee covers the installation.

What the job includes

  • Matching or combination flashing kits for windows side by side
  • Underlay dressed and taped around every frame
  • Rafters trimmed and doubled where the openings need them
  • Combination flashings — We order combination flashings where windows sit close together.
  • Approved loft drawings — We work to the window positions on your approved loft drawings or agree changes with your builder first.

Fitting your loft roof window, step by step

On the day, you need to be in at the start and at the end. In between, the fitters get on with it. They will want the room below cleared where possible, a parking spot if you have one, and somewhere to set the unit down safely. After checking the opening and the upstand or flashing, they fix a loft roof window, seal it and finish the inside. Packaging and any old unit leave with them unless the quote says otherwise.

Planning, building control and Altrincham

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

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 make good inside after fitting?

Yes, where the quote includes it. Internal finishing usually means lining the reveal with plasterboard, taping or skimming, and fitting trim where it meets the ceiling. Some people prefer their own plasterer or decorator to finish off, which is fine. The written quote spells out exactly where our work stops, so nobody is left guessing about who does what once the unit is in.

Can you fit the loft roof window I bought online?

Yes, fit-only is one of our core services. Send the product link or spec, photos of the roof and rough sizes, and we can usually price it from those. Before fitting we check the delivery for damage, which should be reported to the seller, plus the size against the opening, the flashing kit and the roof pitch. The product warranty stays with the maker or seller, and our guarantee covers the fitting.
