What flat roof work do we do in Norwich?
Commercial flat roofing
We are flat roof specialists, so a commercial roof in Norwich gets a system chosen for the job: single-ply for large, simple areas, built-up felt where there is foot traffic and plant, or a liquid overlay where the existing roof is sound. The survey explains the trade-offs in plain terms.
Flat roof replacement
A mineral felt roof laid decades ago may still look intact from the ground in Norwich, yet have lost its chippings, cracked at the laps and pulled away at the upstands. Those faults let water track under the covering, so by the time a ceiling stain appears, the deck has often been wet for some time.
Garage roofs
If your garage in Norwich has an old cement sheet roof, it will eventually crack and let in water. Any suspected asbestos is tested and removed by a licensed specialist first, then the garage can be given new timbers, a deck and a modern membrane that should last for decades with sensible maintenance.

What flat roofs are typical in and around Norwich?
In a large town like Norwich flat roofs are mostly on newer estates where the first extension roofs are now being replaced and terraced streets with flat-roofed rear kitchens and bathrooms. Weather matters on a flat roof. The East of England is the driest part of Britain, with parts of the Anglian region around 630 mm a year, so summer heat and UV, not rainfall, do most of the ageing on a felt roof. Approximate 1991–2020 regional averages based on Met Office data.
Who approves flat roof work in Norwich?
Where approval is needed it goes to Norwich City 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.
