What flat roof work do we do in Croydon?
Torch-on felt roofing
Torch-on is a good fit in Croydon when the budget matters but quality cannot slip. Modern polyester-reinforced membranes typically last 15 to 25 years, high-performance systems longer, and manufacturer material guarantees are available on many specified systems, registered where the system allows.
GRP fibreglass roofing
Landlords and small businesses in Croydon often favour GRP on roofs that contractors need to access for plant, aerials or gutter clearance. The surface resists scuffs better than a soft membrane, and small damage can usually be ground back and re-laminated without disturbing the rest of the roof.
Green and sedum roofs
Rainwater from flat roofs in Croydon 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.

What flat roofs are typical in and around Croydon?
In a town like Croydon flat roofs are mostly on Victorian and Edwardian terraces with flat-roofed back additions and kitchen extensions and roof terraces behind period houses. Weather matters on a flat roof. The Thames basin is one of the drier parts of Britain at roughly 730 mm of rain a year, but summer heat is the bigger test here: dark membranes on south-facing roofs swing a long way in temperature. Approximate 1991–2020 regional averages based on Met Office data.
Who approves flat roof work in Croydon?
Where approval is needed it goes to London Borough of Croydon 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.
