Covering SW15 and neighbouring districts
Covering Roehampton means covering the people who live and work there, not a single postcode. We take on domestic and commercial jobs in SW15, SW14 and SW13, and are happy to quote further out in Putney and Barnes. If your address sits between towns, tell us and we will confirm whether it falls in our normal area or needs travel set out separately on the quote.
Your walk-on rooflights or ours
A damaged delivery is a frequent snag on fit-only work. Before the day, unpack a walk-on 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.
On the day, we cover
- Unit bedded and fixed so it sits level with the finished surface
- Engineer's calculations and the unit's loading data checked together
- Protective film removed and the anti-slip surface left clean
- Non-fragile is not walk-on — We make sure the unit is genuinely designed for foot traffic.
- Structural calculations — We need structural calculations for the glass and its support before a walk-on job goes ahead.
A typical installation 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 walk-on 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 to two days.
Planning and building rules in England
In England, a new rooflight opening generally needs building regulations approval because the roof structure is altered and the glazing must meet energy rules: 2.2 W/m²K for a rooflight in an existing home, or 1.4 W/m²K (or WER Band B) for a roof window. Planning is often not needed on a house: permitted development covers rooflights that stand no more than 0.15 m proud of the roof slope and sit below the highest part of the roof. Flats, listed buildings and areas with an Article 4 direction are different, so we check your address first.
What to send for a quick quote
A fast quote needs five things: a photo of the roof from outside, one from the room below, rough sizes of the opening or the space, the roof covering (felt, single-ply, fibreglass, tiles, slate or metal), and a note on access. If you have already bought the unit, add the product link or spec sheet. And give us the postcode, SW15 or a neighbouring district.
Common questions in Roehampton
Does a rooflight need building regulations approval?
A new opening usually needs building regulations approval. A replacement is a controlled fitting: it must be self-certified by an installer registered with a competent person scheme or notified to building control. We are not registered with a scheme, so replacements we fit are notified to building control with a building notice, and the council's fee is shown on your quote.
How long does fitting take?
Fitting a walk-on rooflight into an existing, correctly sized opening is often a day's work. New openings take longer, because joists or rafters need trimming, an upstand or flashing has to be built or fitted, and the inside needs finishing. Large units that need lifting gear, and days lost to rain, can stretch things further. Your written quote gives a realistic estimate for your roof.
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.
Send a few photos and your SW15 postcode, and we will put together a written quote for the job.
