What flat roof work do we do in Durham?
Torch-on felt roofing
Where a flat roof in Durham already has a felt covering and the building owner wants like-for-like, torch-on is the natural replacement. The old roof is stripped, the deck checked and the new layers laid, often with warm-roof insulation added when the space below is heated.
Warm roof insulation upgrades
Landlords with flats and HMOs in Durham sometimes hear from tenants about cold top-floor rooms and black mould on ceilings. A warm roof upgrade during re-roofing tackles both the heat loss and the condensation behind the mould, and helps keep the roof timbers dry.
Balconies and roof terraces
Settled, rocking or cracked paving is a common reason to re-waterproof a terrace in Durham. Slabs bedded directly on the membrane can damage it over time. Relaying them on adjustable pedestals protects the waterproofing and gives a level surface that drains underneath.

What flat roofs are typical in and around Durham?
In a town like Durham flat roofs are mostly on low-rise post-war blocks of flats and bungalows with flat-roofed side extensions and dormers. The climate is part of the brief. England averages roughly 870 mm of rain a year; the North East is drier than the west but cold and windy near the coast, so wind uplift and freeze-thaw are in the specification. Approximate 1991–2020 regional averages based on Met Office data.
Who approves flat roof work in Durham?
Where approval is needed it goes to Durham County 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.
