New rooflight in an existing roof in Amersham

Guide prices in Amersham

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 Amersham

If you also own a property or a business unit in Chesham, Chalfont St Peter or Gerrards Cross, that is no problem. We can survey and quote both, and where it suits, line the fitting days up together. Every address is reached by fitters travelling to it from their current jobs, and HP7, HP6 and HP8 sit comfortably within that pattern.

Your rooflights or ours

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

• Joists or rafters trimmed with new timbers to carry the load around
• Roof membrane, felt or tiles made good and dressed up the upstand
• Survey of joist direction, roof build-up, ceiling void and access
• Cables, pipes and ceiling fittings — We look into the ceiling void for anything in the way of the new opening.
• Which way the joists run — We check the direction and size of the joists before fixing the rooflight's position.

What happens on the day

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 new rooflight, seal it and finish the inside. Packaging and any old unit leave with them unless the quote says otherwise.

Do you need permission in Amersham?

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.

Getting a price from photos

Start with your phone. Take a picture of the roof where the unit goes or already sits, then one from inside looking up. Measure what you can, even roughly. Tell us what the roof is covered with and how a fitter would reach it: ladder, garden access or scaffold. Bought it already? Send the link or spec. Add your full postcode, for example in HP7, and we can price it.
