Most roof repairs in Farnham cost between £150 and £900, and the majority fall at the lower end of that range. A handful of slipped tiles, a resealed flashing or a small area of repointing is usually a same-day job costing £150–£400. Larger work — replacing a lead valley, re-bedding a run of ridge tiles, or rebuilding a section of verge — runs £400–£900. The figure depends far more on the nature of the fault than on the size of your house.
The single most important part of any repair is correct diagnosis. Water travels: the wet patch on your ceiling is often several feet from where water actually enters the roof. A roofer who patches the visible symptom without finding the source leaves you with a repair that fails at the next heavy rain. We trace every leak back to its origin before quoting — which sometimes reveals a simpler and cheaper fix than the presenting problem suggests, and sometimes reveals that what looked like one issue is actually two.
Replacing one to five slipped or cracked tiles typically costs £150–£300, depending on access and whether matching tiles need sourcing. Ridge re-pointing runs around £25–£45 per metre. A failed lead flashing at a chimney or abutment is usually £200–£500 to put right. A leaking valley — one of the most common causes of ingress on Farnham's older roofs — costs £400–£900 depending on length and whether it's lead or a preformed system.
A repair that treats the symptom rather than the cause is no bargain at any price. If one roofer quotes £150 to reseal a flashing and another quotes £350 to strip it back and relay it properly, the higher quote may be the one that actually lasts. Mastic and sealant smeared over a failed lead flashing will hold for a season, then fail worse than before. Ask what's actually being done, not just what it costs.
Farnham's mix of housing eras produces a predictable pattern of repair calls, and knowing the local stock means we usually have a good idea of the likely fault before we're on the roof. On the Victorian and Edwardian terraces around Hale Road and Firgrove Hill, the most common call is nail sickness — original iron fixings corroding and letting slates slip, even though the slates themselves are sound. The right answer there is often re-nailing a slope rather than a full re-slate, which is a repair, not a replacement.
On the post-war concrete-tile estates in Heath End, Badshot Lea and Upper Hale, the pattern is different: ridge and hip mortar failing after decades of weathering, and tiles beginning to slip as the original nails corrode. These are straightforward repairs while they're caught early, but left unaddressed a single slipped tile becomes a wet valley becomes a rotten batten.
Every autumn, the wooded roads — The Bourne, Frensham Road and the tree-lined streets towards Tilford — generate a wave of leak calls that trace back to one cause: blocked valleys and gutters. Leaf fall packs the valleys, water backs up under the tile courses, and finds its way into the structure. Many of these aren't really roof faults at all — they're maintenance failures that a £100 gutter clear would have prevented. It's the most avoidable repair we attend in Farnham.
Repairs on the period properties around The Borough and Castle Street carry an extra consideration: materials must match, and mortar must be lime, not cement. A cement repair on soft Victorian brickwork causes spalling within a decade — a more expensive problem than the one it was meant to solve. We carry lime mortar as standard for period work and source matching tiles and slate where repairs are visible.
The Association of British Insurers distinguishes sudden insured events such as storm damage from gradual deterioration, which is excluded from buildings cover as a maintenance responsibility — which is why prompt repair of small faults protects both your roof and any future claim.Source: ABI

"Slipped tiles after a windy week. They came out, quoted £220, did it the same afternoon. No call-out fee, no upsell to a new roof. Exactly what you want."
"Leaking valley on our Victorian terrace. Two other roofers wanted to re-roof the whole thing. These fixed the valley for a few hundred pounds and it's been dry since. Honest."
"Chimney flashing repair on a 1960s house in Heath End. Clear written quote, tidy work, explained what they were doing. Reasonable for the amount of leadwork involved."

No. We don't charge a call-out fee anywhere in Farnham or the surrounding area. The cost of attending, inspecting and quoting is built into the job price if you proceed, or there's no charge if you decide not to.
For urgent repairs — active leaks, storm damage, safety concerns — we offer same-day attendance across Farnham where possible. Call 0125 244 7622 and we'll confirm availability and a realistic response time.
Water travels along battens and rafters before it drips, so the internal stain is often several feet from the actual entry point. This is why proper diagnosis matters — we trace the leak to its source rather than patching where the water appears.
If under 20% of the roof is damaged and the rest is sound, repair is almost always better value. We give an honest assessment at survey stage — if your roof genuinely needs replacing we'll say so, but we won't push a re-roof when a repair will do.
Yes — all our repair work carries a 10-year workmanship guarantee. If a repair we've carried out fails within that period, we return and put it right at no charge.
Usually because they're treating the symptom rather than the cause — mastic over a failed flashing instead of relaying the lead, for example. A cheap repair that fails next winter costs more in the end. Ask what's actually being done.
