What flat roof work do we do in Portadown?
Flats, HMOs and block roofs
When a roof over heated flats in Portadown is replaced, insulation rules usually apply. We design the warm-roof build-up towards the required standard where that is feasible and handle building control where it is needed, so the work is signed off properly and the top-floor flats are better insulated.
Green and sedum roofs
Rainwater from flat roofs in Portadown runs off quickly in heavy showers. A green roof holds some of that water back and releases it more slowly, which is one reason some owners and developers choose one. The flowering sedum also draws in bees and other insects.
Warm roof insulation upgrades
Kitchen extensions in Portadown, as elsewhere, produce a lot of moisture from cooking. Under a cold flat roof, that moisture can condense on the deck. A warm roof keeps the deck warm and puts a vapour control layer in the way, which lowers the risk considerably.

What flat roofs are typical in and around Portadown?
In a town like Portadown flat roofs are mostly on 1960s and 1970s link-detached houses with flat-roofed garages and porches and lock-up garage blocks on estates. Weather matters on a flat roof. Northern Ireland averages roughly 1,150 mm of rain a year, spread over many wet days, so a roof that sheds water quickly to clear outlets lasts far longer than one that holds puddles. Approximate 1991–2020 regional averages based on Met Office data.

Where approval is needed it goes to Armagh City, Banbridge and Craigavon Borough Council building control.
