What flat roof work do we do in Banbury?

Liquid-applied roofing

Liquid systems suit balconies and walkways in Banbury because they form neatly at door thresholds, railings and drains, and some products are designed to take foot traffic. Converting a roof into a new terrace is a different matter, and usually needs planning permission first.

Single-ply membrane roofing

For a commercial roof in Banbury with rooflights, plant and outlets, single-ply's welded details give a consistent finish. Pre-formed corners, membrane-coated trims and welded kerbs are all made in the same material as the main roof, which keeps the roof consistent and simplifies any future repairs.

Flat roof surveys and leak tracing

Older extensions and garages in Banbury frequently have felt roofs that have been patched several times. Before paying for another repair, many owners want to know whether the roof has much life left. That is exactly the question a condition survey answers.

What flat roofs are typical in and around Banbury?

In a town like Banbury flat roofs are mostly on terraced streets with flat-roofed rear kitchens and bathrooms and newer estates where the first extension roofs are now being replaced. The climate is part of the brief. Much of the South East sits in the drier Thames catchment at roughly 730 mm of rain a year, so the usual failures are at joints, upstands and outlets rather than from sheer volume of rain. Approximate 1991–2020 regional averages based on Met Office data.

Who approves flat roof work in Banbury?

Where approval is needed it goes to Cherwell District 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.
