What flat roof work do we do in Wigan?
Torch-on felt roofing
On larger roofs in Wigan with poor falls, torch-on felt pairs well with tapered insulation, which builds the fall into the insulation boards. That deals with ponding properly while adding insulation, rather than patching the low spots and waiting for the next leak.
Green and sedum roofs
Garden rooms and outbuildings in Wigan, as elsewhere, often have small flat roofs that are seen from the house and garden. A sedum finish helps them blend in, provided the structure is strong enough and the roof underneath is built properly.
Warm roof insulation upgrades
Kitchen extensions in Wigan, 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 Wigan?
In a city like Wigan flat roofs are mostly on bungalows with flat-roofed side extensions and dormers and terraced streets with flat-roofed rear kitchens and bathrooms. Weather matters on a flat roof. The North West is one of England's wetter regions, averaging roughly 1,290 mm of rain a year, so falls, outlets and well-detailed upstands matter more than the membrane colour. Approximate 1991–2020 regional averages based on Met Office data.
Who approves flat roof work in Wigan?
Where approval is needed it goes to Wigan 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.
