Cage Green is one of Tonbridge's largest post-war residential estates — predominantly 1960s and 1970s housing with concrete interlocking tile roofs that are now entering the age range where nail sickness and tile carbonation become serious issues. We work throughout Cage Green regularly and know exactly what these roofs need. Free inspection, honest assessment, written quote.

More detail →Cage Green was developed primarily in the 1960s and 1970s on the north side of Tonbridge, bounded by Cage Green Road, Shipbourne Road and the northern bypass. The estate covers a substantial area of semi-detached and detached housing, built largely to the standard specifications of the era: concrete interlocking tile roofs, three-layer felt flat roofs on rear extensions, and galvanised steel nails fixing the tiles to the battens. Those nails are now 50-60 years old.
Nail sickness — the progressive corrosion of the original galvanised fixings — is the dominant roofing issue we attend to in Cage Green. Once the zinc coating on a fixing nail has failed and the steel core begins to rust, the nail expands slightly as it corrodes, cracking some tiles and eventually losing grip on others. Tiles begin to slide down the slope, initially by 20-30mm, later falling clear. The process is gradual enough that many Cage Green homeowners don't notice until several tiles have moved — by which point the felt beneath may already be exposed to UV and beginning to break down.
In descending order of frequency: nail sickness re-nailing on rear slopes (the south-facing rear of a north-Tonbridge property takes more direct sun, and UV breakdown of the existing felt is fastest there); flat roof failures on rear kitchen extensions (original felt now 40-50 years old, often re-felted once already); ridge mortar failure (OPC cement from original construction is now cracking throughout); and lead flashing failure on chimney aprons. The southern boundary of Cage Green near Haysden Country Park also generates above-average gutter blockage from leaf fall.

"Nail sickness on both rear and front slopes — tiles had been sliding for two seasons. Re-nailed throughout with stainless steel fixings, ridge re-bedded at the same time. Very thorough, explained exactly what they were doing and why. Competitively priced."
"Kitchen extension flat roof had been patched twice before. New GRP system fitted — they checked the deck before quoting and replaced one rotten section. No surprises on the final bill. Completely dry since."
"Emergency call after storm — three tiles off the front slope, one on the garage roof. On-site within two hours, made safe that afternoon, permanent repair the next morning. Exactly what you need. Will be booking the full roof inspection in spring."
From the garden: look for tiles that are sitting lower than their neighbours — even 20-30mm displacement is visible once you know what to look for. Tiles resting against the gutter are a clear sign. We offer free on-roof inspections that confirm the extent — call 0173 224 1138.
If fewer than 30% of tiles on a slope are affected and the tile surfaces are not carbonated, targeted re-nailing is significantly cheaper. If failure is widespread or tiles are carbonating, full replacement is better value over 20 years. A free survey tells you which situation you're in.

Cage Green is the area we know best in north Tonbridge — we work there more frequently than anywhere else in the post-war estate stock. The estate was built in phases from the early 1960s, and the roofing failure patterns across different streets reflect those phases: earlier streets on the western side show more advanced nail sickness than the 1970s eastern sections; the properties backing onto Haysden Country Park have above-average moss and gutter problems. We carry the right tile profiles for Cage Green's concrete interlocking stock as a matter of routine.
No call-out fee. No obligation. We know Cage Green — the properties, the problems, the right fix.
