Professional flat roofing across Wanstead (E11/E12). Free quotes, 10-year guarantee, no call-out fee.
Wanstead is one of East London's most affluent areas with large Edwardian and 1930s properties along Cambridge Park, Overton Drive, and The Shrubberies. Original Welsh slate roofs on the grander Edwardian homes, concrete interlocking tiles on inter-war semis. The Wanstead Park conservation area mandates like-for-like materials on listed and locally listed properties. Several roads have detached properties with complex roof geometry — multiple hips, valleys, and chimney stacks.
The most common flat roof job in Wanstead is rear extension replacement on Victorian and Edwardian terraces. Properties along Cambridge Park and Overton Drive typically have 1970s–90s felt flat roofs on kitchen and bathroom extensions that are now past their 10–15 year design life. We replace these with GRP fibreglass (£80–£105/m², 25-year guarantee) or EPDM rubber (£65–£90/m², 20-year guarantee), including tapered insulation to create proper drainage falls and meet Building Regulations thermal requirements.
Bay window flat roofs are the second most common job — small 3–5m² roofs where original zinc or lead has corroded after 40–60 years. GRP or EPDM replacement costs £500–£1,200 and provides a maintenance-free finish that does not attract thieves.
All our flat roof replacements in Wanstead use warm deck construction — insulation above the structural deck, beneath the waterproof covering. This keeps the entire structure warm and dry, eliminating the condensation risk that plagues cold deck designs. For properties in E11/E12, the thermal upgrade alone reduces heating costs through the extension by 10–15% from the first winter.

“Valley replacement on our Victorian terrace. Old lead was paper-thin and leaking at every lap joint. New Code 5 lead valleys with proper soakers at every slate course. Beautifully done.”
“Our Becontree Estate semi needed a complete re-roof — the 1930s clay tiles were crumbling and the battens underneath were rotten. Four days from start to finish, new concrete tiles, all new battens and felt. Looks brilliant.”
“They felted our flat garage roof as a temporary measure while we save for GRP. Honest about it being a 10-year solution, quoted fairly, and the workmanship is excellent for a budget option.”
