What flat roof work do we do in Leigh?
Flat roof surveys and leak tracing
Buyers in Leigh sometimes find a general survey flags a flat roof as a concern without saying much more. A specific flat roof survey fills that gap, describing the condition and likely cost of any work so it can be factored into the decision.
Extension and kitchen roofs
Rooflights fitted after the roof was built are a frequent source of trouble in Leigh extensions. If the kerb was not formed properly or the membrane was simply sealed around the frame, leaks follow. Replacing the roof is the chance to rebuild every upstand to a proper standard.
Green and sedum roofs
If you're replacing an old flat roof in Leigh, it's worth deciding whether to add sedum at the same time. If the structure can take it, that is the ideal moment, because the waterproofing is new and the green layers won't need lifting for a long time.

What flat roofs are typical in and around Leigh?
In a town like Leigh flat roofs are mostly on shops with flat-roofed rear stores below flats and bungalows with flat-roofed side extensions and dormers. Local weather shapes the specification. 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 Leigh?
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.
