New rooflight in an existing roof in Crowthorne

Crowthorne 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.

Areas around Crowthorne we cover

Jobs across RG45, GU47 and RG40 are part of our normal cover for Crowthorne. 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 Sandhurst and Yateley are covered on the same terms, so a house on the edge of town is no harder to book than one in the centre.

Your rooflights or ours

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 new rooflight 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.

Included in the work

• Roof membrane, felt or tiles made good and dressed up the upstand
• Plasterboard reveals formed inside and left ready for skim or decoration
• Rooflight fitted, sealed and checked for even clearance on every side
• Cables, pipes and ceiling fittings — We look into the ceiling void for anything in the way of the new opening.
• Planning for your roof — We check whether the new rooflight falls within permitted development for your house and nation.

What happens on the day

Arrive and agree the plan. Sheet the floor and furniture. Set up the ladder, tower or scaffold. Check the opening, the upstand or flashing, and the unit against the paperwork. Fix and pack a new rooflight level. Seal it into the roof. Line the reveal or fit the ceiling trim. Clean the glass, clear the waste, and talk you through it. That is the shape of most fitting days, and for this type of job it usually takes two to three days.

Planning and building rules in England

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.

Help us quote accurately

Keep it simple. Two or three photos, outside and inside. Approximate sizes. What the roof is made of. Anything awkward about getting up there, such as a conservatory below, a narrow side path or no parking. If you bought the rooflight online, the link or model name. Then your postcode in or around RG45. That is enough for a first price.
