Case Study

A reroofing project for Scarborough Borough Council using Permavent APEX.

Westpier, Scarborough

A tiled roof with Permavent APEX underlay

A building owned by Scarborough Borough Council required a new tiled roof, including a new underlay membrane. To preserve the aesthetic of the original roof and provide excellent condensation control without having to add ventilation at low or high elevations Permavent APEX was chosen for its air and vapour permeability. The roof was stripped and a new one installed by Waring Building & Roofing Ltd, who chose APEX to complete the project.

Why Permavent was chosen

Permavent APEX was chosen for its air and vapour permeability which allows for condensation control and removes the need to add ventilation to the roof in either low or high areas. After inspecting samples and deliberating Ashley Waring of Waring Building & Roofing Ltd chose Permavent APEX and Permavent RED to be the business’ go-to membranes, saying “[Permavent APEX is] possibly the best membrane we have used”.

How Permavent Products were installed:

Permavent APEX was installed as per the manufacturer’s instructions and building standards regulations, in compliance with BS5534 & BS5250.
