Which flat roofs are common in Norfolk?
Rain and wind decide how a flat roof is detailed. 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. Across Norfolk, flat roofs are typically found on bungalows with flat-roofed side extensions and dormers, shops with flat-roofed rear stores below flats and 1930s semis with flat-roofed garages and kitchen extensions. Approximate 1991–2020 regional averages based on Met Office data.
Which flat roof jobs do we take on in Norfolk?
Emergency leak repairs
Landlords with flats or HMOs in Norfolk are generally expected to deal with leaks promptly once tenants report them. An emergency visit stops the water, and our written report and quote give you what you need to approve the permanent repair.
Single-ply membrane roofing
If a flat roof in Norfolk has poor falls and ponding, a single-ply re-roof with tapered insulation can correct both problems at once. The tapered boards build the fall into the insulation, and the membrane is laid over the top, with outlets set at the new low points.
Commercial flat roofing
Businesses in Norfolk need a roofing contractor who arrives with a plan, not just a price. We put the system, build-up, phasing, access and payment terms in a fixed written quote, and keep each section of the roof watertight before the team leaves site, so trading is not put at risk.
Building regulations in England
Replacing more than half of a flat roof over a heated room usually counts as renovating a thermal element, so the roof is insulated to around 0.16 W/m²K where that's technically and economically feasible, and the work is notified to building control: the council or a registered building control approver, unless a registered competent person self-certifies it. A roof on a new extension is built to 0.15 W/m²K. Patch repairs, and most unheated detached garages, don't trigger the upgrade. Structural changes, or a new covering that adds 15% or more to the roof's weight, also need approval. More on the rules.
