Cocklebury sits between central Chippenham and the Pewsham development, with moderate exposure. The 1970s and 1980s housing creates a maintenance profile that bridges the nail sickness era and the flat roof era.
1970s properties are entering the early nail sickness phase — still at the optimal intervention window where phased re-roofing is cost-effective. 1980s additions have flat roofs and UPVC guttering now 40–45 years old.
Early nail sickness on 1970s properties is the primary emerging call — tiles loosening rather than displacing at the Hardenhuish rate. 1980s flat roof failures are the secondary category, with fascia and gutter deterioration across both eras.
Cocklebury is at the optimal intervention point for nail sickness — early enough to phase the work, late enough that the problem is confirmed rather than suspected. We advise on the most cost-effective intervention for each slope's condition.
Single installation: £400–£700. Replacement: £200–£450. Flat roof light: £500–£900. Flashing repair: £150–£350. Free quote — call 01249 247 076.

01249 247 076Knowing Cocklebury means knowing its roofs. Cocklebury is a Chippenham district of 1960s–70s concrete-interlocking-tile housing close to the town centre and the railway. We have worked on this stock for years, so we recognise nail sickness across the concrete-tile roofs, dropped ridge and verge mortar, and end-of-life felt underlay on sight, quote accurately the first time, and do not need to guess at what is behind the covering. Cocklebury sits low near the Avon and the railway on the north-east of the town. — local knowledge that goes straight into how we specify and price the work.
