Timber upstand
Treated timber kerb built square and level to the maker's size
Insulated upstand
Kerb with insulation and the roof membrane turned up and dressed
Large or with trimming
Bigger kerbs or where joists need trimming first
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.
Fitting across Rhyl and nearby
If you also own a property or a business unit in Prestatyn, Colwyn Bay or Llandudno, that is no problem. We can survey and quote both, and where it suits, line the fitting days up together. Every address is reached by fitters travelling to it from their current jobs, and LL18, LL19 and LL17 sit comfortably within that pattern.
On the day, we cover
- Treated timber frame fixed down to the deck and joists
- Roof membrane turned up, bonded and finished at the kerb top
- Diagonals measured so the kerb is square before anything sits on it
- Size tolerance on the kerb — We build kerbs to a tight tolerance because rooflight glass is made to order and cannot be trimmed on site.
- 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.
How a fitting day runs
Building an upstand starts with the rooflight's own drawing: its kerb size, height above the finished roof and fall. The team sets the timber out to those figures, checks the diagonals, insulates the outer faces and dresses the membrane up and over. If the rooflight is going on the same day, it is fitted next; if not, the kerb is protected until it does.
Regulations for Rhyl properties
For a Welsh home, start with where the house is. In a conservation area, National Park, AONB or World Heritage Site, a rooflight needs planning permission; outside those, permitted development usually covers one that projects 150 mm or less. Side-facing roof windows within 10.5 m of a boundary must be obscure-glazed and fixed. New openings need building regulations approval, and replacements we fit are notified with a building notice, as we are not registered with a competent person scheme. We confirm all of this for your address.
Help us quote accurately
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, LL18 or nearby, confirms travel.
Common questions in Rhyl
Does a rooflight need building regulations approval?
In Wales a new opening generally needs building regulations approval. A replacement must be self-certified by a scheme-registered installer or covered by a building notice. We are not registered with a scheme, so replacements we fit go through a building notice, and the council's fee is shown on your quote.
Do you cover Rhyl?
Yes. Fitters travel to addresses in Rhyl and the surrounding districts, including LL18. 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.
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.
Send a few photos and your LL18 postcode, and we will put together a written quote for the job.
