Guide ranges for labour and materials, rooflight not included. 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.
Coverage in and around Hemel Hempstead
Fitters travel to the job, so the address is what counts. In Hemel Hempstead that means postcode districts HP2, HP3 and HP1, and the same teams can just as easily take on work in Berkhamsted, about 5 miles away, or St Albans at roughly 5 miles. Survey and fitting dates are offered according to fitter availability, and travel is built into the quote rather than added later.
What we do on the day
- Diagonals measured so the kerb is square before anything sits on it
- Kerb sized from the maker's drawing, internal and external dimensions both checked
- Roof membrane turned up, bonded and finished at the kerb top
- Roof covering compatibility — We check what the roof is covered in before choosing how the membrane meets the kerb.
- Fall built in or level — We confirm whether your rooflight needs the kerb to provide a fall or should sit level.
How a fitting day runs
The fitters measure twice before cutting: the opening, the rooflight's kerb size and the finished roof level. The kerb is built, packed level or to the maker's fall, insulated and weathered into the roof covering. You are left with an upstand ready for the rooflight, and a note of the sizes it was built to.
Regulations for Hemel Hempstead properties
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
What we cannot see, we have to guess, and guesses make quotes wider. So the more you send, the tighter the price. Useful: shots from the roof or garden, shots from the room underneath, a rough width and length, the roof finish, any access problems, and the product page if you have already ordered. Add the property postcode around HP2 and we will come back with a quote or a survey date.
Common questions in Hemel Hempstead
Do you cover Hemel Hempstead?
Yes. Fitters travel to addresses in Hemel Hempstead and the surrounding districts, including HP2. 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.
How does payment work?
Payment terms are set out on your written quote before you accept it. Depending on the job, that may mean a deposit, stage payments for larger work, or payment on completion. The contract is with S&K Property Investments and Improvement Ltd, part of the S&K Group. Nothing is added without your agreement: if something unexpected comes up, we discuss it and agree any change before carrying on.
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.
