Frameless rooflight installation in Northampton

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 frameless rooflight in Northampton, 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.

Areas around Northampton we cover

Looking at a property near Northampton but not quite in it? We work across NN1, NN2 and NN3 and outwards to Wellingborough, Daventry and Rushden. Give us the full postcode when you get in touch, because access, parking and the route for a large unit all depend on the exact street. Those details shape the quote for any job around Northampton.

Your frameless rooflights or ours

Supply and fit tends to suit people who would rather not pick a unit from a catalogue. We look at the roof, the opening and how you use the room, then put a frameless rooflight on the quote that fits all three. Fit-only suits people who already know what they want, or have one on site. We are happy with either. The difference is who stands behind what: on fit-only, the maker or retailer covers the product, and our workmanship guarantee covers the installation.

What we do on the day

  • Fall set in the upstand so rain clears the oversailing glass edge
  • Upstand built to the maker's drawing within its stated tolerance
  • Glass bedded on the specified tape or sealant and fixed through the concealed frame
  • How the reveal will look — We agree the finish at the glass edge before building anything.
  • Tolerance on the upstand — We build frameless kerbs to the maker's tolerance rather than to normal carpentry accuracy.

From arrival to clean-up

Morning first: the team arrives, introduces itself and walks through the job with you. Dust sheets go down in the room below and along the route in. Then the opening and upstand, or the flashing on a pitched roof, are checked against the unit's measurements. A frameless rooflight goes in, is fixed to the maker's pattern and sealed into the roof covering. Inside, the reveal is finished as quoted. Before leaving, the team clears debris and talks you through what was done. Most jobs of this type take one day.

Planning, building control and Northampton

England's rules in short: permitted development usually covers a rooflight on a house roof provided it doesn't stick out more than 0.15 m or rise above the ridge, though a listed building always needs consent and some streets have Article 4 directions. Building regulations apply to new openings, and replacements go through building control; as we are not registered with a competent person scheme, we use a building notice and show the fee on the quote. The energy limit for rooflights in existing homes is 2.2 W/m²K, and the 2026 Approved Document L, in force from 24 March 2027, keeps that figure.

What to send for a quick 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 NN1. That is enough for a first price.

Common questions in Northampton

Do you cover Northampton?

Yes. Fitters travel to addresses in Northampton and the surrounding districts, including NN1. 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.

Will my new frameless rooflight leak?

A correctly fitted unit should not. Leaks usually trace back to the detail around the frame: an upstand that is too low, a membrane or flashing that is not dressed properly, sealant applied to a damp surface, or water ponding against the kerb. We fit to the maker's instructions and check each of those points. The fitting carries a written workmanship guarantee, with its terms set out on your quote.

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.
