Trade rooflight fitting in Dorset

Trade rooflight fitting across Dorset follows one method wherever the roof is. First a survey or, for fit-only work, your photos and measurements. Then a written quote with the scope and price fixed. Then a fitting day planned around the weather. We list 7 towns in Dorset on this site, each with its own page, but villages and addresses between them are covered in exactly the same way. Fitters travel to the property, so there is no need to be near any particular town.

Towns we list in Dorset

Builders and roofers working in Dorset can use us for the rooflight element of a job, wherever the site is in England. Homeowners can book us directly. In both cases the fitters come to the address, the work follows the maker's instructions, and a written quote fixes the price first. Fitting is carried out by vetted teams under S&K's direction.

Included in the work

  • Supplied units checked against your schedule before fitting
  • Flat rooflights fitted, sealed and trimmed on your kerbs
  • Upstands built by us where you would rather not
  • Upstand ready and to size — We ask for the upstands to be built to the maker's drawing before we arrive.
  • Deliveries and damage — We check delivered units against the schedule before fitting.

Rules that apply in England

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 agree up front who notifies it. 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.

Common questions in Dorset

What if my roof opening is the wrong size for the rooflight?

We find out before the fitting day, not on it. If the opening is slightly out, it can usually be adjusted by trimming or by packing out the upstand. If it is a long way off, the choice is between altering the opening and changing the unit. Bear in mind that rooflights are often sold by builder's opening size rather than external size, so check which one your measurement refers to.

What is included in the price?

The written quote lists it line by line. Typically that covers fitting labour, fixings, sealants, membrane or flashing materials, any upstand work, internal finishing if agreed, and taking away the waste. For supply and fit, the unit itself is included too. Scaffold, lifting gear and any third-party fees, where needed, are shown separately so you can see what each part of the job costs.

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.
