How we approach smoke vent rooflights (AOVs) in Birkenhead
Thinking about smoke vent rooflights (AOVs) in Birkenhead? The short answer: automatic smoke ventilators at the head of stairwells and atria. The longer answer depends on your roof, which is why we survey before we price.
Rear kitchen extensions on North West semis often have small domes from decades ago that leak or have yellowed. Smoke vent rooflights (AOVs) suit blocks of flats and commercial buildings with a smoke strategy.
Birkenhead sits about 3 km from Liverpool and 5 km from Wallasey, and we cover the whole CH41 postcode district and the roads in between.
