Rooflight upstands & kerbs in Bodmin

Building an upstand in Bodmin starts with the rooflight's own drawing, not a standard size. The kerb has to match the unit's internal dimensions, stand high enough above the finished roof for water to run off, and be level or pitched as the maker asks. We set the timber out to those figures, check the diagonals, insulate and weather it. If the rooflight is not on site yet, send us its make and model so the kerb is built for it.

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 Bodmin and nearby

Distance is rarely the deciding factor. A roof in St Austell, 9 miles from Bodmin, gets the same survey, the same written quote and the same fitting process as one in PL31, PL30 and PL22. What changes the price is the job itself: size of unit, roof type, access and lifting. Newquay, around 16 miles out, is treated the same way.

On the day, we cover

  • Fall built into the kerb where the rooflight needs one
  • Kerb sized from the maker's drawing, internal and external dimensions both checked
  • 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.

What happens on the day

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.

Planning, building control and Bodmin

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

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, PL31 or nearby, confirms travel.

Common questions in Bodmin

Do I need planning permission for a rooflight in Bodmin?

Often not. Many rooflights fall under permitted development, provided they do not project beyond the national limit and meet the other conditions that apply in England. Conservation areas, listed buildings and some flats are different and may need consent. Because the rules depend on the property, we confirm what is likely to apply at your address and point you to the planning authority where an application is needed.

Do you make good inside after fitting?

Yes, where the quote includes it. Internal finishing usually means lining the reveal with plasterboard, taping or skimming, and fitting trim where it meets the ceiling. Some people prefer their own plasterer or decorator to finish off, which is fine. The written quote spells out exactly where our work stops, so nobody is left guessing about who does what once the unit is in.

Do you cover Bodmin?

Yes. Fitters travel to addresses in Bodmin and the surrounding districts, including PL31. 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.
