What flat roof work do we do in Nailsea?
Flat roof surveys and leak tracing
Businesses in Nailsea with a flat-roofed building can't plan maintenance around guesswork. A survey sets out what needs doing now, what can wait and roughly what each item will cost, so the work can be scheduled with as little disruption as possible.
Warm roof insulation upgrades
Landlords with flats and HMOs in Nailsea 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.
Flat roof repairs
Older flat roofs in Nailsea, as elsewhere, are often covered in felt that has lost its chippings and dried out. One leak on a roof like that is a warning sign. We repair it, check the rest of the covering and tell you honestly whether replacement belongs in next year's budget.

What flat roofs are typical in and around Nailsea?
In a town like Nailsea flat roofs are mostly on bungalows with flat-roofed side extensions and dormers and low-rise post-war blocks of flats. Rain and wind decide how a flat roof is detailed. The South West averages roughly 1,260 mm of rain a year and many roofs face wind off the Atlantic, so we specify fixings and edge details for wind uplift as well as drainage. Approximate 1991–2020 regional averages based on Met Office data.
Who approves flat roof work in Nailsea?
Where approval is needed it goes to North Somerset 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.
