What flat roof work do we do in Dorchester?
Flat roof repairs
Older flat roofs in Dorchester, 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.
Garage roofs
Water from a failing garage roof in Dorchester does not always stay in the garage. On an attached garage it can run down the house wall or track under the flashing, and a blocked or broken gutter can spill onto the drive or a neighbour's property. Replacing the roof deals with the source.
Liquid-applied roofing
Liquid roofing suits a roof in Dorchester that is full of penetrations, such as soil pipes, vents, aerial brackets and rooflights, because the liquid flows around each one and cures into a single skin. There are no cut pieces or taped corners to work loose over time.

What flat roofs are typical in and around Dorchester?
In a town like Dorchester 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. 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 Dorchester?
Where approval is needed it goes to Dorset 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.
