Which flat roofs are common in Oxfordshire?
Weather matters on a flat roof. 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. Across Oxfordshire, flat roofs are typically found on 1960s and 1970s link-detached houses with flat-roofed garages and porches, terraced streets with flat-roofed rear kitchens and bathrooms and newer estates where the first extension roofs are now being replaced. Approximate 1991–2020 regional averages based on Met Office data.
Which flat roof jobs do we take on in Oxfordshire?
Commercial flat roofing
We are flat roof specialists, so a commercial roof in Oxfordshire gets a system chosen for the job: single-ply for large, simple areas, built-up felt where there is foot traffic and plant, or a liquid overlay where the existing roof is sound. The survey explains the trade-offs in plain terms.
Garage roofs
If your garage in Oxfordshire 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.
Extension and kitchen roofs
If you're fitting a new kitchen under an extension in Oxfordshire, that's a good time to replace the roof. It makes sense to rebuild the roof before fitting new units, ceilings and lighting below, and the insulation upgrade makes the room more comfortable all year.
Building regulations in England
Replacing more than half of a flat roof over a heated room usually counts as renovating a thermal element, so the roof is insulated to around 0.16 W/m²K where that's technically and economically feasible, and the work is notified to building control: the council or a registered building control approver, unless a registered competent person self-certifies it. A roof on a new extension is built to 0.15 W/m²K. Patch repairs, and most unheated detached garages, don't trigger the upgrade. Structural changes, or a new covering that adds 15% or more to the roof's weight, also need approval. More on the rules.
