What flat roof work do we do in Dereham?
Balconies and roof terraces
Door thresholds are a common reason for balcony work in Dereham. Where a door was fitted with a low step-out and no drainage channel, water driven against the frame finds its way under the sill. Re-waterproofing gives the chance to rebuild that detail properly.
Flat roof repairs
Small businesses in Dereham 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.
Flat roof replacement
Flat roofs in Dereham get replaced for the same reasons as anywhere else: the covering has reached the end of its service life, leaks keep returning after repairs, or water ponds because the deck has sagged. Once the boards are soft or the insulation is wet, a full strip usually costs less than another round of patching.

What flat roofs are typical in and around Dereham?
In a town like Dereham flat roofs are mostly on lock-up garage blocks on estates and bungalows with flat-roofed side extensions and dormers. The climate is part of the brief. 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 Dereham?
Where approval is needed it goes to Breckland 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.
