What flat roof work do we do in Sunbury-on-Thames?
GRP fibreglass roofing
Landlords and small businesses in Sunbury-on-Thames 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.
Balconies and roof terraces
A roof terrace in Sunbury-on-Thames may be re-waterproofed when the owners want to change the finish, swapping old tiles for decking or porcelain on pedestals. Lifting the surface exposes the membrane, and replacing it then avoids having to lift the new finish again later.
Green and sedum roofs
In a place like Sunbury-on-Thames, many people look out over a flat extension or garage roof from upstairs. Grey felt or rubber isn't much of a view, and a sedum roof turns it into something green that changes colour through the seasons and flowers in summer.

What flat roofs are typical in and around Sunbury-on-Thames?
In a town like Sunbury-on-Thames flat roofs are mostly on newer estates where the first extension roofs are now being replaced and terraced streets with flat-roofed rear kitchens and bathrooms. 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 Sunbury-on-Thames?
Where approval is needed it goes to Spelthorne Borough 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.
