What flat roof work do we do in Daventry?

Green and sedum roofs

Garden rooms and outbuildings in Daventry, as elsewhere, often have small flat roofs that are seen from the house and garden. A sedum finish helps them blend in, provided the structure is strong enough and the roof underneath is built properly.

Flat roof surveys and leak tracing

Landlords and managing agents in Daventry often need a written record of a roof's condition, for budgeting, for leaseholders, or to show a problem has been looked at properly. A survey report gives them a clear basis for deciding when to repair and when to replace.

Garage roofs

If your garage in Daventry has an old cement sheet roof, it will eventually crack and let in water. Any suspected asbestos is tested and removed by a licensed specialist first, then the garage can be given new timbers, a deck and a modern membrane that should last for decades with sensible maintenance.

What flat roofs are typical in and around Daventry?

In a town like Daventry flat roofs are mostly on newer estates where the first extension roofs are now being replaced and terraced streets with flat-roofed rear kitchens and bathrooms. Local weather shapes the specification. The East Midlands is drier than the west of Britain, so most flat roofs here fail through age, UV and poor detailing at upstands rather than sheer rainfall. Approximate 1991–2020 regional averages based on Met Office data.

Where approval is needed it goes to West Northamptonshire Council building control, or a registered building control approver.
