Ruberoid produces a wide range of underslating membranes, primarily to be installed below tiles, slates or metal roofing providing a secondary barrier against wind driven rain, snow and dust. Some like Rubershield-Pro, also allow the roof to breathe, negating the requirement for traditional ventilation, while other products perform specialist roles like eaves protection or securing overlap joints.

This guide will help you choose your underslating materials and understand the other products needed to complete your project.

Historically underslatings were Hessian reinforced bitumen membranes. These are still available from Ruberoid together with other high performance polyester based bitumen underslatings. Although trusted for many years, they’re unsuitable for modern warm roof or unventilated cold roof applications.

Breather membranes are very popular and increasingly used on a wide range of projects. Their adaptable, multipurpose use is seen by specifiers, merchants and installers as the optimum solution to underslating requirements, simplifying design, stock control and installation requirements on site.
