What flat roof work do we do in Northampton?

Green and sedum roofs

Rainwater from flat roofs in Northampton runs off quickly in heavy showers. A green roof holds some of that water back and releases it more slowly, which is one reason some owners and developers choose one. The flowering sedum also draws in bees and other insects.

Liquid-applied roofing

Where a building in Northampton has an older asphalt or concrete roof that is sound but tiring, a compatible liquid system can sometimes refresh it. The key is matching the primer and system to the substrate and dealing with any blisters, cracks or poor falls before the membrane goes on.

Flats, HMOs and block roofs

Service charge budgets for blocks in Northampton do not always stretch to a whole roof at once. We can phase a re-roof over more than one budget year, pricing each phase separately in writing and keeping every section watertight in between, so the building stays protected while the cost is spread.

What flat roofs are typical in and around Northampton?

In a city like Northampton flat roofs are mostly on low-rise post-war blocks of flats and bungalows with flat-roofed side extensions and dormers. 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.

Who approves flat roof work in Northampton?

Where approval is needed it goes to West Northamptonshire 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.
