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.
Fitting across Grays and nearby
Distance is rarely the deciding factor. A roof in Swanscombe, 2 miles from Grays, gets the same survey, the same written quote and the same fitting process as one in RM17, RM16 and RM20. What changes the price is the job itself: size of unit, roof type, access and lifting. South Ockendon, around 3 miles out, is treated the same way.
Already bought your unit?
There are two ways to do this. Supply and fit means we source a replacement rooflight that suits your roof and install it, so one company answers for both the product choice and the fitting. Fit-only means you buy the unit and we install it. With fit-only, the product warranty stays with the maker or seller, and our written guarantee covers the fitting work. Both routes get the same checks on the opening, the upstand and the maker's instructions before anything is fixed.
What the job includes
- Packers, an adaptor or a new insulated upstand where the old kerb falls short
- Old rooflight or dome unscrewed, lifted out and taken away for disposal
- New unit bedded, fixed and sealed exactly as its maker shows
- Leaks that are not the rooflight — We look at the roof around the unit before blaming the rooflight.
- Dome to glass upgrades — We check that the opening and kerb suit a flat glass unit before quoting a dome-to-glass swap.
Fitting your replacement rooflight, step by step
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 replacement 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 one day.
Regulations for Grays properties
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.
What to send for a quick quote
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 RM17 and we will come back with a quote or a survey date.
Common questions in Grays
What if my roof opening is the wrong size for the replacement rooflight?
We find out before the fitting day, not on it. If the opening is slightly out, it can usually be adjusted by trimming or by packing out the upstand. If it is a long way off, the choice is between altering the opening and changing the unit. Bear in mind that rooflights are often sold by builder's opening size rather than external size, so check which one your measurement refers to.
Do you cover Grays?
Yes. Fitters travel to addresses in Grays and the surrounding districts, including RM17. 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.
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.
Got a unit waiting to go in, or need one sourced? Either way, start with your Grays address and a couple of photos.
