Loft conversion roof windows in Atherton

Our guide price for loft conversion roof windows starts from £1,795, and the real figure for your roof in Atherton depends on a handful of things: the size and type of loft roof window, whether the opening exists already, the roof covering, and how easy access is. We fix the price in a written quote before work begins. Nothing gets added on the day without your say-so. For a rough idea first, photos and a couple of measurements are enough to go on, and we cover all of Greater Manchester.

Coverage in and around Atherton

Distance is rarely the deciding factor. A roof in Tyldesley, 1 mile from Atherton, gets the same survey, the same written quote and the same fitting process as one in M46, M29 and BL5. What changes the price is the job itself: size of unit, roof type, access and lifting. Westhoughton, around 2 miles out, is treated the same way.

Already bought your unit?

Your unit or ours, the fitting standard is the same. For supply and fit we choose a loft roof window to suit the roof and price it with the installation. For fit-only we work with what you have, after confirming it arrived undamaged, that it matches the builder's opening, and that the upstand will sit at the height the maker asks for. Report any transit damage to the seller, as the product cover is theirs and the maker's. Our written guarantee applies to the fitting itself.

Included in the work

  • Insulation collars fitted so the room's insulation meets each frame
  • Matching or combination flashing kits for windows side by side
  • Underlay dressed and taped around every frame
  • Fitting stage and weather — We plan when the windows go in around the rest of the conversion.
  • Approved loft drawings — We work to the window positions on your approved loft drawings or agree changes with your builder first.

A typical installation day

Morning first: the team arrives, introduces itself and walks through the job with you. Dust sheets go down in the room below and along the route in. Then the opening and upstand, or the flashing on a pitched roof, are checked against the unit's measurements. A loft roof window goes in, is fixed to the maker's pattern and sealed into the roof covering. Inside, the reveal is finished as quoted. Before leaving, the team clears debris and talks you through what was done. Most jobs of this type take one to two days.

Do you need permission in Atherton?

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.

Help us quote accurately

Each detail you send takes a question off our list. Photos inside and out show the opening and the ceiling. Rough measurements tell us the unit size. The roof covering tells us how it will be sealed in. Access notes tell us whether a tower or scaffold is needed. A product link, if you have one, lets us check it against the opening. Your postcode, M46 or nearby, confirms travel.

Common questions in Atherton

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.

Can you remove and dispose of the old rooflight?

Yes. Taking out the old unit is part of any replacement job, and it leaves with the rest of the waste unless you ask to keep it. Old domes, glass and frames go through proper waste routes. If removal turns up a rotten kerb or damaged decking, we show you what we have found and agree the repair with you before going any further.

Do you cover Atherton?

Yes. Fitters travel to addresses in Atherton and the surrounding districts, including M46. 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.
