Farnborough has the highest density of end-of-life concrete tile housing in Hampshire. The large post-war estates in Cove and Southwood — built between 1955 and 1970 — are now 55–70 years old. Many properties on these estates are presenting widespread surface carbonation on tiles, open ridge mortar, and flat garage roofs well past their service life simultaneously.
Flat roofing in Farnborough requires correct drainage specification above all else. The minimum recommended fall for a flat roof is 1:80 — roughly 12mm per metre. Many failed flat roofs we inspect in Farnborough were installed with inadequate falls, causing ponding that saturates the membrane and backing. We re-profile decks where required as part of any flat roof installation.
Farnborough's high housing density means roofing contractors are in high demand here — particularly in spring and after autumn storms. Booking ahead rather than waiting for an emergency is good practice for Farnborough homeowners.
The dense suburban tree planting on Farnborough's 1960s estates generates significant leaf fall every autumn. Gutter and valley clearance is the most important annual maintenance task for properties on these estates.
"New GRP roof on the extension. Perfectly level, good drainage, no issues in 18 months including a very wet winter. Far better than the old felt."
"Garage flat roof replaced in EPDM. Half a day's work, very tidy. Explained the drainage issue with the old roof clearly and sorted it properly."
"Had three quotes for the flat roof on the back extension. Went with these because they identified a drainage problem the others missed. Right call."
GRP fibreglass is our standard recommendation for most Farnborough properties — fully seamless, longest lifespan and maintenance-free. EPDM is preferable for larger areas or unusual shapes. Felt is a cost-effective option where budget is the primary constraint.
GRP fibreglass 25–30 years. EPDM rubber 20–25 years. Quality torch-on felt 15–20 years. Traditional built-up felt 10–15 years. Lifespan depends heavily on correct installation — particularly adequate drainage falls.
Flat roof replacements like-for-like don't require planning permission. If you're adding a new flat roof where there wasn't one before, or raising the height, permitted development rules apply and we'll advise at survey stage.
The most common causes in Farnborough are ponding water from inadequate falls, failed seams or edges on older felt roofs, and cracked or blistered surfaces. We identify the exact cause before recommending repair or replacement.
