Which flat roofs are common in East Sussex?

Local weather shapes the specification. 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 East Sussex, flat roofs are typically found on bungalows with flat-roofed side extensions and dormers, low-rise post-war blocks of flats and terraced streets with flat-roofed rear kitchens and bathrooms. Approximate 1991–2020 regional averages based on Met Office data.

Which flat roof jobs do we take on in East Sussex?

Liquid-applied roofing

Choose liquid roofing in East Sussex when the shape of the roof makes sheet materials awkward: curved edges, small dormers with many corners, or a mix of levels joined by short upstands. Each detail is reinforced in the same material as the main area, so the whole roof is continuous.

GRP fibreglass roofing

Landlords and small businesses in East Sussex often favour GRP on roofs that contractors need to access for plant, aerials or gutter clearance. The surface resists scuffs better than a soft membrane, and small damage can usually be ground back and re-laminated without disturbing the rest of the roof.

Green and sedum roofs

Garden rooms and outbuildings in East Sussex, 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.

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.
