Eave Protection & Underlayment (Architectural Metal Roofing)

Accepted Materials for a RoofStar Guarantee

The tables and products shown below provide basic material data and links to more information about the materials, including manufacturers' published Technical Data sheets, but this information is not intended for use as a comparison of material performance or quality. It is the sole responsibility of the Design Authority to assess the performance capability and material suitability for specific design requirements.

The materials listed are those which have been accepted by the RoofStar Guarantee Program (RCABC Guarantee Corp., or RGC) for use in a roof or grade-level waterproofing system that will qualify for a RoofStar Guarantee. The acceptance of these materials by the RGC (RoofStar Guarantee Program) in no way reflects on the quality or performance of other materials not listed.

The materials and guideline specifications are listed under the name of the manufacturer and/or supplier of the primary membrane material, with the exception of BUR membranes for which the reader will find RoofStar Guarantee Program guidelines on traditional built-up roofing systems (BUR) incorporating organic and glass felt primary membranes.

For reference, consult the RoofStar Guarantee Standards for ASM Roof Systems eave protection, underlayment and valleys.

The problems resulting from the presence of condensation represent one of the major causes of damage to the structure and fabric of old and modern buildings alike. They are, therefore, of great importance to the specifier in his design role. The increased use of insulation and modern roof construction methods have created further major condensation risks within the roof void.

The specifier must ensure that the risk of condensation is minimised by ensuring the correct design, suitable ventilation in accordance with the B.C. Building Code, and specification of the most suitable underlay.

RoofStar-guaranteed metal roofing systems require a suitable underlay to ensure that any moisture produced by condensation is not introduced into the roofing system components or the structure of the building. Modified bituminous membranes that are not arranged under insulation must have a high softening point bitumen with a minimum flow temperature of 87.7°C (190°F) to prevent material displacement from heat transfer through metal panels during high temperature days. (See UNDERLAYMENT - Eave and Detail Protection (ASM Roof Systems)). All accepted modified bituminous self-adhesive membranes listed exceed a minimum flow temperature of 87.7°C (190°F.).

Accepted No. 30 Asphalt felt or RoofStar-accepted proprietary synthetic underlayments that meet or exceed the CSA A123.3 standards for No. 30 Asphalt Felt are acceptable for use on uninsulated wood decks sloped over 4" in 12". Manufacturer's limitations are to be followed.

For RoofStar-accepted No. 30 asphalt felts refer to BUR Felts in the Accepted Materials section of this Manual.
