ASTM D7505/D7505M-17(2023)

Standard Specification for Self-Adhesive Polyester Fabric Reinforced Polymer-Modified Asphalt Steep Slope Roll Roofing Surfaced with Mineral Granules

ABSTRACT
This specification covers prefabricated, self-adhesive, polyester fabric reinforced, polymer-modified asphalt surfaced roll roofing products, with granule surfacing, designed for steep slope applications. These products use polymer modifiers in their top and bottom coatings and have an adhesive bottom layer which is exposed by removal of a peel-away protective release paper or film sheet. The specified tests and property limits used to characterize the sheet materials are intended to establish minimum properties. The minimum physical properties required for the sheet include thickness, peak load, elongation, tear strength, adhesion to plywood, side lap integrity, thermal stability, and granule loss.
SCOPE
1.1 This specification covers prefabricated, self-adhesive, polyester fabric reinforced, polymer-modified asphalt surfaced roll roofing products, with granule surfacing, designed for steep slope applications. These products use polymer modifiers in their top and bottom coatings. These products have an adhesive bottom layer which is exposed by removal of a peel-away protective release paper or film sheet.  
1.2 The specified tests and property limits used to characterize the sheet materials are intended to establish minimum properties. In-place roof system design criteria such as fire resistance, field strength, impact/puncture resistance, material compatibility, uplift resistance, and others, are factors beyond the scope of this material specification. Factors regarding the suitability of specific roof constructions or application techniques are beyond this scope.  
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

Overview

ASTM D7505/D7505M-17(2023): Standard Specification for Self-Adhesive Polyester Fabric Reinforced Polymer-Modified Asphalt Steep Slope Roll Roofing Surfaced with Mineral Granules defines requirements for prefabricated, self-adhesive roofing sheets. These sheets are reinforced with polyester fabric and use polymer-modified asphalt surfacing, topped with mineral granules, and are specifically designed for steep slope roofing applications. The standard establishes minimum physical and performance properties for these roll roofing products, such as thickness, tensile strength, elongation, tear strength, adhesion, dimensional stability, thermal stability, and granule loss.

Polymer-modified asphalt roofing sheets described by this standard have an adhesive layer on the bottom that is protected by a peel-away release sheet, allowing for quick and effective installation. The products are engineered to ensure dependable waterproofing and durability on steep sloped roofs.

Key Topics

• Composition and Structure

  • Polyester fabric reinforcement for strength and stability
  • Polymer-modified asphalt coatings on both top and bottom surfaces
  • Weather-exposed face finished with uniformly distributed mineral granules
  • Bottom self-adhesive layer covered by a protective release film or paper

• Essential Performance Properties

  • Minimum thickness and peak load requirements to ensure durability
  • Elongation and ultimate elongation to accommodate thermal and structural movement
  • Tear strength and side lap integrity for ongoing protection against environmental factors
  • Adhesion to plywood across a range of temperatures
  • Dimensional and thermal stability to resist expansion, contraction, and flow
  • Control of granule loss for long-term surface protection

• Quality and Workmanship

  • Requirements for uniform finish, proper granule embedment, and freedom from defects
  • Criteria for packaging, marking, and inspection

Applications

Products specified under ASTM D7505/D7505M-17(2023) are widely used in the roofing industry, particularly in steep slope roofing systems, such as those found in residential, commercial, and institutional buildings. Typical practical applications include:

• Primary steep slope roofing membrane – Installed as the main waterproofing barrier on pitched roofs.
• Underlayment for steep slope roofing – Used beneath shingles, tiles, or metal roofing for added protection.
• Self-adhered installation – Offers ease of application without the need for hot asphalt or torches, improving safety and reducing installation time.
• Re-roofing and renovations – Suitable for upgrading existing steep slope roofing systems, thanks to its flexibility and adhesive backing.

The roofing sheets deliver effective protection against water ingress, resist tears and deformation, and maintain granular surface integrity under various weather and operational stresses. This specification helps ensure minimum performance characteristics for manufacturers, designers, installers, and building owners.

Related Standards

ASTM D7505/D7505M-17(2023) references and aligns with several related ASTM roofing standards, enhancing the reliability and compatibility of roofing materials in the industry:

• ASTM D903: Test Method for Peel or Stripping Strength of Adhesive Bonds
• ASTM D1079: Terminology Relating to Roofing and Waterproofing
• ASTM D4977/D4977M: Test Method for Granule Adhesion to Mineral-Surfaced Roofing by Abrasion
• ASTM D5147/D5147M: Test Methods for Sampling and Testing of Modified Bituminous Sheet Material

Adherence to these related standards ensures robust testing methods and consistency in defining roofing product quality.
