New rooflight in an existing roof in Allerton

Guide prices

Guide ranges for supply & fit, including structure and making good; building control or warrant fees extra. 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.

Coverage in and around Allerton

Jobs across L19, L18 and L25 are part of our normal cover for Allerton. We are not an office on the high street. Our fitting teams come out to the property from wherever they are working that week. Neighbouring places such as Garston and Halewood are covered on the same terms, so a house on the edge of town is no harder to book than one in the centre.

Already bought your unit?

Your unit or ours, the fitting standard is the same. For supply and fit we choose a new rooflight 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

• Survey of joist direction, roof build-up, ceiling void and access
• Roof membrane, felt or tiles made good and dressed up the upstand
• Insulated upstand built square, level and to the maker's height
• Which way the joists run — We check the direction and size of the joists before fixing the rooflight's position.
• Cables, pipes and ceiling fittings — We look into the ceiling void for anything in the way of the new opening.

What happens on the day

Protection comes before tools. Floors, furniture and stairs get covered, and the ceiling below the opening is sheeted to catch dust. Up top, the fitters confirm the opening is square and the upstand or flashing suits what the maker specifies. Fixing follows, then weather-sealing into the membrane, felt or tiles. Only once the roof is tight do they turn to the internal reveal. Time on site for a new rooflight: two to three days, weather permitting.

Planning, building control and Allerton

Two sets of rules matter in England. Planning: a rooflight on a house is normally permitted development if it projects no more than 0.15 m and stays below the highest part of the roof, but flats, listed buildings and Article 4 areas need checking. Building regulations: new openings need approval for the structure and energy performance, and a replacement is a controlled fitting. We are not registered with a competent person scheme, so we notify replacements to building control with a building notice and put the council's fee on the quote.

Before you get in touch

What we cannot see, we have to guess, and guesses make quotes wider. So the more you send, the tighter the price. Useful: shots from the roof or garden, shots from the room underneath, a rough width and length, the roof finish, any access problems, and the product page if you have already ordered. Add the property postcode around L19 and we will come back with a quote or a survey date.
