Smoke vent rooflight installation in Coleraine

A rooflight is not finished when the roof is watertight. The inside matters too: the reveal or lining around the opening, the plaster, the trim where it meets the ceiling. Some installers leave that for somebody else. When we quote for smoke vent rooflight installation in Coleraine, internal finishing is listed so you can see whether it is included or left for your decorator. That way a smoke vent rooflight looks right from the room below as well as from outside. We cover Coleraine and properties throughout County Londonderry.

Fitting across Coleraine and nearby

Coleraine and the districts around it, BT52, BT55 and BT56, all sit inside our working area. So does the ground between Coleraine and Ballymena (24 miles), and on towards Derry/Londonderry (27 miles). When a fitting team is booked, their travel is already in the quoted price, so it does not turn up as a surprise line on the final bill.

What the job includes

  • Old vent removed with the stairwell kept protected below
  • Existing vent, actuator and upstand surveyed with the specialist
  • Certified vent and actuator matched to the opening and controls
  • Free area at the stair head — We check the free area the vent must provide before choosing a replacement.
  • Certified as a system — We only fit smoke vents that are certified to BS EN 12101-2.

From arrival to clean-up

Fitting days start with a look at the sky. If rain is due, the order of work changes so the roof is never left open to it. A typical day for a smoke vent rooflight runs like this: set up access, protect the room, open up the roof or prepare the existing kerb or frame, check sizes, fix, seal, then finish inside. On jobs that take more than a day, the opening is weather-sealed overnight. The last hour goes on tidying, waste removal and a walk-round with you.

Do you need permission in Coleraine?

Replacing a smoke vent in Northern Ireland means keeping the certified performance and free area of the system, with a specialist commissioning the controls. We confirm with you whether building control needs to be involved.

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, BT52 or nearby, confirms travel.

Common questions in Coleraine

What if my roof opening is the wrong size for the smoke vent rooflight?

We find out before the fitting day, not on it. If the opening is slightly out, it can usually be adjusted by trimming or by packing out the upstand. If it is a long way off, the choice is between altering the opening and changing the unit. Bear in mind that rooflights are often sold by builder's opening size rather than external size, so check which one your measurement refers to.

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.

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.
