Eave Protection & Underlayment (Asphalt Shingles, Cedar Shakes & Shingles)

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 eave protection, underlayment and valleys:

  1. Asphalt Shingles
  2. Cedar Shakes & Shingles


Eave protection is used to protect the eave and valley areas of steep sloped roofs from ice dam damage. An ice dam usually forms when the interior heat of the building warms the snow on the roof, causing it to melt and run down to the eaves. Normally, the eaves are overhanging the building and not heated from the inside. This allows the water to freeze and form an ice dam. As the ice dam grows bigger, it forms a barrier, which prevents water from draining. The water backs up behind the dam and gradually forces its way under the shingles (or shakes, tiles, etc.), through the roof deck, and into the structure. The results can range from minor staining to severe water damage to the structural members.

Eave protection is designed to prevent the water from reaching the deck and leaking into the structure. Recently a number of companies have developed self-adhesive, rubberized asphalt composite sheet materials. Properly formulated and installed, these sheets have the potential to provide a longer life and better performance. The slope and climate conditions are considerations for selection, please refer to Asphalt Shingles Roof Systems.

Underlayment is used in the field areas (where eave protection is not required) of the roof to provide a secondary protection beneath the shingles during weather events that force water back up the slope underneath the shingles. Nail Applied materials qualify only as underlayment on roof slopes of more than 1:3 (4/12).
