What flat roof work do we do in Corby?

Flat roof repairs

Flat roofs in Corby face the same enemies as anywhere else: rain driven against walls, leaves blocking outlets, sun drying out older felt and frost opening small cracks. People tend to notice when a stain appears on a ceiling after a storm, or when water is still sitting on the roof days after rain.

Emergency leak repairs

Older felt roofs in Corby that have lost their chippings dry out and crack, and a cold snap can open those cracks enough to let water through. A temporary repair stops the immediate leak, but a roof like that often needs a frank conversation about replacement.

Green and sedum roofs

In a place like Corby, many people look out over a flat extension or garage roof from upstairs. Grey felt or rubber isn't much of a view, and a sedum roof turns it into something green that changes colour through the seasons and flowers in summer.

What flat roofs are typical in and around Corby?

In a large town like Corby flat roofs are mostly on terraced streets with flat-roofed rear kitchens and bathrooms and shops with flat-roofed rear stores below flats. Rain and wind decide how a flat roof is detailed. The East Midlands is drier than the west of Britain, so most flat roofs here fail through age, UV and poor detailing at upstands rather than sheer rainfall. Approximate 1991–2020 regional averages based on Met Office data.

Who approves flat roof work in Corby?

Where approval is needed it goes to North Northamptonshire Council building control, or a registered building control approver. Replacing more than half of a roof over a heated room usually counts as renovating a thermal element, so it is insulated to current standards and notified to building control. How the rules work.
