Flat roofs on extensions, garages and bay tops in The Bourne need the right specification. We install GRP fibreglass, EPDM rubber and torch-on felt systems with correct drainage falls and a 20-year guarantee on GRP.
The Bourne's 1920s–1960s housing stock means flat roofs here are often on extension additions built 30–50 years ago and now at end of life. The Bourne runs along a wooded valley south of Farnham. Heavy tree canopy creates significant leaf fall and persistent shade on north-facing slopes — highest moss growth rate of any Farnham neighbourhood. Getting drainage right for local conditions is as important as membrane choice.
Mix of 1920s–30s detached properties and post-war semis in a wooded setting south of Farnham. Clay tile dominant on older stock, concrete on post-war. Heavy tree canopy throughout.
Very high moss growth rate due to tree canopy and valley shade. Valley and gutter blockages every autumn. Concrete tile erosion on post-war properties. Flat roof garage additions needing replacement.
The Bourne runs along a wooded valley south of Farnham. Heavy tree canopy creates significant leaf fall and persistent shade on north-facing slopes — highest moss growth rate of any Farnham neighbourhood.
The Bourne has the highest moss growth rate of any Farnham neighbourhood due to valley humidity and heavy deciduous tree canopy. Annual gutter and valley clearance is essential — twice yearly for heavily canopied plots.

The Bourne's wooded valley setting creates the highest moss growth rate of any Farnham neighbourhood. The combination of valley humidity, north-facing slopes, and heavy deciduous canopy means roofs here can become significantly colonised within 3–4 years of the last treatment. For The Bourne properties, annual autumn gutter clearance and 4-yearly moss treatment is our minimum maintenance recommendation.

GRP fibreglass is our standard recommendation for The Bourne — seamless, 25+ year lifespan and maintenance-free. EPDM is better for larger areas. Torch-on felt is the budget option. We advise on the right choice at survey stage.
GRP: 25–30 years. EPDM: 20–25 years. Quality torch-on felt: 15–20 years. Lifespan depends heavily on correct drainage falls — ponding water is the primary cause of flat roof failure.
GRP on a standard extension (up to 20m²) in The Bourne costs £1,200–£2,000. EPDM on the same area costs £1,000–£1,800. Torch-on felt: £800–£1,500. Free written quotes provided.
