Which flat roofs are common in Isle of Wight?

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 Isle of Wight, flat roofs are typically found on terraced streets with flat-roofed rear kitchens and bathrooms, low-rise post-war blocks of flats 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 Isle of Wight?

Torch-on felt roofing

Torch-on felt suits property owners in Isle of Wight who want a dependable, layered roof without paying the top price per square metre. With two or three bonded layers, a single small defect in one sheet need not lead to a leak, which is a real advantage on larger roofs that are hard to inspect often.

Warm roof insulation upgrades

Small commercial buildings in Isle of Wight with large flat roofs can lose a lot of heat through them. Where the roof is being replaced, upgrading the insulation at the same time is required in most cases and helps reduce running costs for the occupier.

GRP fibreglass roofing

For a garage or extension in Isle of Wight that doubles as a step-out space for window cleaning, GRP gives a firmer footing than a rubber membrane. With an anti-slip topcoat it handles light, occasional use, though a full terrace needs its own specification and, in many cases, planning permission.

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.
