1.1 This practice covers procedures for performing visual monitoring of roofing construction to: 1.1.1 Establish guidelines for quality assurance observation practices; and 1.1.2 Define the role and responsibilities of the quality assurance observer. 1.2 This practice pertains to quality assurance observation of roofing projects and the report of information obtained from these observations. This practice is applicable to new construction or reroofing projects involving the installation of a new roof system, the removal of existing roofing and installation of a new roof system, or recovering an existing roof. It is also applicable to roofing projects involving repairs or scheduled maintenance to an existing roof. 1.3 This practice contains the following information: 1.3.1 The objectives of the quality assurance process; 1.3.2 The responsibilities and qualifications of the individual(s) involved in the observations of the roof construction or repair; 1.3.3 Identification and use of the basic tools or equipment required for the visual roof observation process; and 1.3.4 Monitoring, recording, and reporting procedures. 1.4 This practice addresses new construction or repair. This practice does not address the investigation, condition, or analysis of existing roofs. 1.5 This practice does not address practices of roof investigation, condition reporting, or analysis of preexisting roofs. 1.6 This practice does not pertain to quality control processes or techniques performed by persons or entities representing or under contract to the roofing contractor. The quality control process is separate and distinct from the quality assurance observation process. 1.7 Assessment of safe work practices or safety monitoring procedures followed by the contractor is outside the scope of this practice. 1.8 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. 1.9 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. ====== Significance And Use ====== 4.1 Quality assurance observation of roofing projects is an important process for determining if the removal, installation, repair, or maintenance of roofing materials or systems follows the scope and intent of the contract documents and are installed and executed in accordance with accepted roofing practices and the contract documents. 4.2 This practice is applied to full-time quality assurance observation of roofing projects involving the removal, construction, and repair and maintenance of low and steep-slope roof systems and roofing-related accessories. 4.3 This practice establishes the role and responsibilities of those performing quality assurance observation and includes qualifications of the quality assurance observer, as well as procedures for observation and documentation during the roof construction or repair process. 4.4 If used, nothing in this practice shall be interpreted as precluding the use of all or parts of it while conducting full-time or part-time quality assurance observer (QAO) inspection.
