Smoke vent rooflight installation in Bodmin

Our guide price for smoke vent rooflight installation starts from £3,595, and the real figure for your roof in Bodmin depends on a handful of things: the size and type of smoke vent rooflight, whether the opening exists already, the roof covering, and how easy access is. We fix the price in a written quote before work begins. Nothing gets added on the day without your say-so. For a rough idea first, photos and a couple of measurements are enough to go on, and we cover all of Cornwall.

Fitting across Bodmin and nearby

Jobs across PL31, PL30 and PL22 are part of our normal cover for Bodmin. We are not an office on the high street. Our fitting teams come out to the property from wherever they are working that week. Neighbouring places such as St Austell and Newquay are covered on the same terms, so a house on the edge of town is no harder to book than one in the centre.

On the day, we cover

  • Upstand checked, adapted or rebuilt to the vent maker's drawing
  • Existing vent, actuator and upstand surveyed with the specialist
  • Controls, detection and wiring handled by the smoke-control specialist
  • Upstand and weathering — We check the upstand suits the new vent and that the roof around it is sound.
  • Controls and backup power — We confirm the controls, detection and backup power are being dealt with by a specialist.

What happens on the day

Protection comes before tools. Floors, furniture and stairs get covered, and the ceiling below the opening is sheeted to catch dust. Up top, the fitters confirm the opening is square and the upstand or flashing suits what the maker specifies. Fixing follows, then weather-sealing into the membrane, felt or tiles. Only once the roof is tight do they turn to the internal reveal. Time on site for a smoke vent rooflight: one to two days per vent, weather permitting.

Do you need permission in Bodmin?

A replacement smoke vent in England has to keep the free area and performance the building's fire strategy relies on, using a vent certified to BS EN 12101-2 with its actuator and backup power. We fit the vent and do the roof work; a smoke-control specialist connects and commissions the controls, and we confirm whether building control needs to be notified.

Before you get in touch

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 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.

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.

What upstand height and roof pitch does smoke vent rooflight fitting need?

It depends on the product. Manufacturers usually specify a minimum upstand height above the finished roof surface, and a minimum pitch on the glass so rain runs off. We follow the maker's figures for your unit rather than a rule of thumb. If your existing kerb or roof falls short, we explain the options, such as raising the upstand or choosing a unit with built-in pitch.
