Membranes and underlayments

The Multipurpose Waterproofing Membrane is a 1 mm self-adhesive membrane composed of SBS modified bitumen. This membrane is perfect to waterproof various repair and maintenance works around the house, cottage, or farm.

This self-adhesive waterproofing membrane protects roof eaves, valleys, and penetration points against ice dams and wind-driven rain. Made from elastomeric SBS bitumen with glass mat reinforcement, it maintains flexibility across wide seasonal temperature swings common in Canadian climates. The sanded anti-slip surface provides safe footing during installation on pitched roofs, while the two-part silicone release film allows precise positioning. Self-sealing around nails and screws, it forms a continuous watertight barrier at the most vulnerable areas of any roofing system.

Deliver reliable roof protection with this 40 mil (1 mm) self-adhesive, self-sealing underlayment made of elastomeric bitumen with a trilaminated woven polyethylene surface. The nonslip, flexible sheet installs under any type of roof covering and operates from -40 to 200°F (-40 to 93°C) for year-round performance. Each 36" W x 65' L roll covers 195 sq.ft., enabling continuous, even coverage across roof areas. Easy to handle and secure in place, it supports professional standards and straightforward DIY work for durable, weather-ready installations and repairs.
