Professional flat roofing across Forest Gate (E7). Free quotes, 10-year guarantee, no call-out fee.
Victorian terraces dominate Forest Gate — densely packed rows along Woodgrange Road, Romford Road, and the streets between them. Original Welsh slate roofs with chimney stacks every 5–6 metres along the terraced rows. Some Edwardian properties on wider avenues like Hampton Road retain decorative ridge tiles and finials. HMO conversions are common, adding loft dormers and additional flue penetrations to original roof structures.
The most common flat roof job in Forest Gate is rear extension replacement on Victorian and Edwardian terraces. Properties along Woodgrange Road and Romford Road 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 Forest Gate 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 E7, the thermal upgrade alone reduces heating costs through the extension by 10–15% from the first winter.

“Mansard roof extension in Shoreditch. Complex job with zinc cladding and a flat GRP top. The workmanship is outstanding — every detail is crisp and the weatherproofing is flawless.”
“Emergency call at 11pm on a Saturday — water pouring through our flat roof ceiling. They arrived in just over an hour, tarped the whole area, and came back Monday for the permanent GRP repair. Could not ask for more.”
“They waterproofed our basement extension where it meets the rear wall of the house. Liquid-applied membrane and proper drainage channel. First winter with no damp. Life-changing.”
