South Petherwin Primary School, Thermal Efficiency Upgrade

Over several years, multiple attempts had been made by Cornwall Council to repair the Stonewold tiles and recoat the gutter courses at South Petherwin Primary School, to stem the leaks that had continued to affect multiple classrooms across the site.

Project management surveying firm, Kendall Kingscott, appointed Technical Manager Justyn Irons, to carry out a thorough condition survey to assess the roof build-up and isolate the source of the leaks. During the investigations, Justyn discovered that the main cause of ingress was caused by the wrong tile type being installed on the low-level pitch of the building. The gutters around the hall were too narrow and often blocked with debris, allowing ingress to flow back under the tiles into the building and directly into the classrooms below.
