Trade rooflight fitting in Sunbury-on-Thames

Plenty of rooflight trouble starts with a tape measure. Units are often sold by the builder's opening, meaning the hole in the roof, rather than the overall external size, and confusing the two leaves you with a frame that does not suit the opening. Before we fit any rooflight in Sunbury-on-Thames, we measure the opening, the upstand or kerb where there is one, and the finished roof level, then compare them with the maker's drawing. If something is out, you hear about it before the fitting day rather than on it. That single check keeps most jobs like this on track.

Fitting across Sunbury-on-Thames and nearby

Our fitters come to you. For Sunbury-on-Thames that covers TW16, TW17 and KT12, plus nearby Walton-on-Thames and West Molesey. We do not keep a yard or showroom in the area, and you do not need to visit one. The survey happens at your property or, for fit-only work, from the photos you send. Dates follow fitter availability, which we confirm when you accept the quote.

What the job includes

  • Supplied units checked against your schedule before fitting
  • Upstands checked for size, height, level and square
  • A short note of anything we found that needs your attention
  • Building control sign-off — We agree with you how building control is handled before fitting.
  • Deliveries and damage — We check delivered units against the schedule before fitting.

A typical installation day

Protection comes before tools. Floors, furniture and stairs get covered, and the ceiling below the opening is sheeted to catch dust. Up top, the fitters confirm the opening is square and the upstand or flashing suits what the maker specifies. Fixing follows, then weather-sealing into the membrane, felt or tiles. Only once the roof is tight do they turn to the internal reveal. Time on site for a rooflight: half a day to a day per unit, weather permitting.

Planning and building rules in England

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 on replacements we agree up front who notifies building control.

Getting a price from photos

Each detail you send takes a question off our list. Photos inside and out show the opening and the ceiling. Rough measurements tell us the unit size. The roof covering tells us how it will be sealed in. Access notes tell us whether a tower or scaffold is needed. A product link, if you have one, lets us check it against the opening. Your postcode, TW16 or nearby, confirms travel.

Common questions in Sunbury-on-Thames

Do you need scaffolding to fit a rooflight?

Not always. Single-storey roofs can often be reached safely with ladders, a tower or edge protection. Higher roofs, steep pitches and large units usually need scaffold or a mobile platform, and heavy glass may need a crane. We assess access from your photos or at the survey, and any scaffold or lifting cost is shown as its own line on the written quote.

Do you cover Sunbury-on-Thames?

Yes. Fitters travel to addresses in Sunbury-on-Thames and the surrounding districts, including TW16. 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.

What upstand height and roof pitch does 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.
