Sliding rooflight installation in Hertford

Builders and extension firms in Hertford often want the rooflight stage of a project handled by a specialist fitting team. We step in once the roof deck or battens are ready, fit a sliding rooflight on your upstand or ours, detail it into the membrane or tiles, and leave the opening ready for the plasterer. Homeowners get exactly the same service directly. In each case the job is quoted in writing first, with any access or lifting needs spelt out. Jobs around SG13 and the neighbouring districts are welcome.

Guide ranges for supply & fit. 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.

Is your address covered?

Hertford and the districts around it, SG13, SG14 and SG12, all sit inside our working area. So does the ground between Hertford and Ware (2 miles), and on towards Hoddesdon (4 miles). When a fitting team is booked, their travel is already in the quoted price, so it does not turn up as a surprise line on the final bill.

Buying your own, or letting us supply

Which works out better, buying your own or letting us supply? It depends on what you value. Buying your own gives you control of the product and what you pay for it. Letting us supply puts the whole job, unit and fitting, under one written quote. On a customer-supplied unit we still measure it against the opening, look at the upstand, and inspect the condition it arrived in. Warranty on the product sits with whoever sold it, while the fitting carries our own guarantee.

On the day, we cover

  • Clear run confirmed for the glass to slide over when open
  • Controls, sensors and any safety stop set up and tested
  • Upstand checked for strength, square and level along its full length
  • Guarding on the terrace — We look at how the roof terrace will be guarded before the rooflight is fitted.
  • Weight and lifting — We plan the lift for a sliding rooflight before it is ordered.

What happens on the day

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 sliding rooflight, seal it and finish the inside. Packaging and any old unit leave with them unless the quote says otherwise.

Regulations for Hertford 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

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, SG13 or a neighbouring district.

Common questions in Hertford

How long does fitting take?

Fitting a sliding 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.

Do you cover Hertford?

Yes. Fitters travel to addresses in Hertford and the surrounding districts, including SG13. 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.

Got a unit waiting to go in, or need one sourced? Either way, start with your Hertford address and a couple of photos.
