Guide ranges for supply & fit; building control notice fee extra in England and Wales. 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.
Covering ME4 and neighbouring districts
Jobs across ME4, ME7 and ME1 are part of our normal cover for Chatham. 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 Rochester and Gillingham 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?
A damaged delivery is a frequent snag on fit-only work. Before the day, unpack a replacement rooflight, photograph it, and tell the seller about any cracks or scuffs, because claims are much easier made early. We will also ask for the model or a link, so we can read the maker's instructions and check the builder's opening size and the upstand height it expects. If everything lines up, we fit it. If not, we explain what needs changing first.
What we do on the day
- Building notice given to the council in England and Wales, with its fee on the quote
- Old rooflight or dome unscrewed, lifted out and taken away for disposal
- Roof membrane repaired and turned up where it meets the kerb
- Inside finishes — We check the condition of the plaster and trim around the opening from inside.
- Leaks that are not the rooflight — We look at the roof around the unit before blaming the rooflight.
How a fitting day runs
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 replacement rooflight, seal it and finish the inside. Packaging and any old unit leave with them unless the quote says otherwise.
Planning, building control and Chatham
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.
Details that speed up your quote
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 ME4. That is enough for a first price.
Common questions in Chatham
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.
Do you offer trade rates for builders and roofers?
We carry out subcontract fitting for builders, roofers, extension companies and commercial contractors. Pricing is per job or per schedule of units, agreed in writing before we start. We can work to your programme, fit on your upstand or build our own, and leave the opening ready for the next trade. Send drawings or a unit schedule and we will come back with a trade quote.
What upstand height and roof pitch does replacement rooflight fitting need?
It depends on the product. Manufacturers usually specify a minimum upstand height above the finished roof surface, and a minimum pitch on the glass so rain runs off. We follow the maker's figures for your unit rather than a rule of thumb. If your existing kerb or roof falls short, we explain the options, such as raising the upstand or choosing a unit with built-in pitch.
