What flat roof work do we do in Seaham?
Flat roof surveys and leak tracing
In Seaham, as elsewhere, people often book a survey after a repair that didn't hold. When a leak returns, it usually means the first fix treated the symptom rather than the cause. Tracing the actual entry point saves paying for the same repair twice.
Green and sedum roofs
Small commercial buildings and blocks in Seaham with a flat roof sometimes add an extensive green roof as part of a refurbishment. The structural check and safe access for maintenance matter even more on these larger roofs, which may need edge protection or fall-arrest points for each visit.
Flat roof repairs
In a place like Seaham, flat roofs usually sit over garages, rear extensions, dormers and bays, and they take the full force of the weather with little margin for error. A single failed lap or a cracked upstand is enough to let water into a kitchen, bedroom or hallway below.

What flat roofs are typical in and around Seaham?
In a town like Seaham flat roofs are mostly on lock-up garage blocks on estates and bungalows with flat-roofed side extensions and dormers. Weather matters on a flat roof. 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 Seaham?
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.
