Church Road, Lisvane, Cardiff

March 2019


The roof combines part refurbishment of an existing property, as well as an additional new development:

  • Suitable protection for the high number of roof verge and valleys details.
  • Fibre cement slates specified to be in-keeping with the local area.


This refurbishment/new roof development used the following Permavent products: Easy Valley, Easy Verge and Permavent Black.

As a solution to the number of roof valleys on this property, Easy Valley was installed to provide optimum weather protection to the long length valleys. In addition to this, it provided clean finish to the aesthetics of the roof valley.

Permavent Black was installed as a robust and reliable breathable roof underlay.

Easy Verge further enhanced the weather protection to the roof, as well as the overall finished appearance.

All Permavent products were installed as per our fitting guidelines and was installed alongside a dry ridge/hip system, clay and concrete ridges and fibre cement slates.
