What flat roof work do we do in Bromley?

Green and sedum roofs

Homeowners in Bromley building a new extension may find a green roof can help with a planning application, as some councils encourage them for biodiversity and slower rainwater run-off. It is worth raising early with your designer, before the roof structure is drawn up, so the joists can be sized for the extra weight.

Flat roof repairs

Small businesses in Bromley with a flat-roofed shop, office or unit can't leave a leak running over stock or equipment. A repair stops the water at its entry point, and our inspection tells you whether the rest of the roof needs attention soon or can safely be left for now.

EPDM rubber roofing

If your Bromley roof has been patched more than once and the felt is cracking or blistering, a full replacement in EPDM can be better value than another repair. The rubber stays flexible through hot summers and freezing nights, and the replacement is the right point to bring the insulation up to standard.

What flat roofs are typical in and around Bromley?

In a town like Bromley flat roofs are mostly on mansard and dormer loft conversions and Victorian and Edwardian terraces with flat-roofed back additions. Local weather shapes the specification. 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 Bromley?

Where approval is needed it goes to London Borough of Bromley 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.
