Self-adhesive roofing underlayment for premium roof leak protection on sloping timber boarded roofs

+44 (0)1753 490000 Website

Application

For roof leak protection or sloping timber roofs. Suitable substrates include plywood, wood composition, wood plank, metal, concrete, or gypsum sheathing.

Description

Roofing membrane composed of two waterproofing materials - an aggressive rubber bitumen adhesive backed by a layer of cross laminated HDPE. The rubber bitumen surface is backed with a release paper that protects its adhesive quality. The underlay must be fully supported by the substrate.


Features and benefits:

  • Easy to handle and apply- bonds firmly to the roof deck without heat or special adhesives. Watertight laps are easily formed.
  • Aesthetically pleasing- unlike other forms of ice dam protection, Grace Ice & Water Shield is concealed by the finished roofing, preserving the architectural appearance of the roof.
  • Seals around nails- the rubber bitumen layer seals around roofing nails, resisting leakage caused by water back-up.
  • Dual barrier protection- rubber bitumen and polyethylene are combined to form two waterproofing barriers providing maximum protection.
  • Membrane will not crack, dry out or rot- resists attacks from fungus and bacteria; maintaining its integrity for long lasting protection.
  • Protects under all standard sloped roof coverings- protects under slate, tile, or metal.
  • Slip resistant surface- has a slip resistant embossed surface to maximise traction and safety for applicators.
  • Proven track record.
