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 Kendal
Looking at a property near Kendal but not quite in it? We work across LA9, LA8 and LA7 and outwards to Morecambe, Lancaster and Heysham. 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 Kendal.
What the job includes
- Insulation fitted to the upstand faces to limit heat loss
- Treated timber frame fixed down to the deck and joists
- Diagonals measured so the kerb is square before anything sits on it
- Energy limit for site-built kerbs — We insulate upstands to meet the limit for site-built upstands, which is 0.35 W/m²K in England and Wales.
- Roof covering compatibility — We check what the roof is covered in before choosing how the membrane meets the kerb.
A typical installation day
On the day, the fitters check the opening and the roof deck around it, then cut and fix treated timber to the maker's kerb size, square and level, with any fall the rooflight needs built in. Insulation goes on the faces that need it, and the roof membrane is turned up and dressed so the kerb is weathertight before anyone leaves. Most upstand jobs take half a day to a day.
Regulations for Kendal properties
In England, a new rooflight opening generally needs building regulations approval because the roof structure is altered and the glazing must meet energy rules: 2.2 W/m²K for a rooflight in an existing home, or 1.4 W/m²K (or WER Band B) for a roof window. Planning is often not needed on a house: permitted development covers rooflights that stand no more than 0.15 m proud of the roof slope and sit below the highest part of the roof. Flats, listed buildings and areas with an Article 4 direction are different, so we check your address first.
What to send for a quick quote
Each detail you send takes a question off our list. Photos inside and out show the opening and the ceiling. Rough measurements tell us the unit size. The roof covering tells us how it will be sealed in. Access notes tell us whether a tower or scaffold is needed. A product link, if you have one, lets us check it against the opening. Your postcode, LA9 or nearby, confirms travel.
Common questions in Kendal
Can you remove and dispose of the old rooflight?
Yes. Taking out the old unit is part of any replacement job, and it leaves with the rest of the waste unless you ask to keep it. Old domes, glass and frames go through proper waste routes. If removal turns up a rotten kerb or damaged decking, we show you what we have found and agree the repair with you before going any further.
Can you fit a rooflight in winter or when it is raining?
Yes, within limits. Cold is less of a problem than wet, because membranes, primers and sealants need a dry surface to bond. We plan fitting days around the forecast and may move a date if heavy rain is due. If the roof has to be opened up, it is not left overnight without a temporary weather seal, so the room below stays dry while the work is finished.
Do you cover Kendal?
Yes. Fitters travel to addresses in Kendal and the surrounding districts, including LA9. 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.
Tell us your postcode, LA9 or close by, and what you want fitted. We will reply with the next steps and a quote.
