Sliding rooflight installation in Truro

Guide prices

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.

Fitting across Truro and nearby

Jobs across TR1, TR4 and TR3 are part of our normal cover for Truro. We are not an office on the high street. Our fitting teams come out to the property from wherever they are working that week. Neighbouring places such as Falmouth and Redruth are covered on the same terms, so a house on the edge of town is no harder to book than one in the centre.

What we check on a supplied unit

There are two ways to do this. Supply and fit means we source a sliding 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 we do on the day

• Upstand checked for strength, square and level along its full length
• Clear run confirmed for the glass to slide over when open
• Full open and close cycle checked before handover
• Planning for a roof terrace — We flag early whether planning may be needed for the work around the rooflight.
• Power and safety stops — We confirm the power supply and the safety features before fitting day.

How a fitting day runs

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 sliding 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 to two days.

Do you need permission in Truro?

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.

Help us quote accurately

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, TR1 or a neighbouring district.
