Section 3.1. RoofStar Guarantee Program

3.1.1. Purpose of RoofStar Guarantee

3.1.1.1. Repair or Replacement Coverage for Materials and Workmanship
  1. The RoofStar Guarantee Program provides depreciation-free leak repair coverage for waterproofing and water-shedding systems , for five, ten or fifteen years (the Guarantee Period), up to the limits (Contract Value) stated on the Guarantee Certificate, subject to the conditions and limitations stated in this Part and on the Guarantee certificate .
  2. The RoofStar Guarantee Program provides depreciation-free leak repair coverage, and limited coverage for the repair or replacement of vegetation, for vegetated (“green”) roof assemblies, up to the limits (Contract Value) stated on the Guarantee Certificate, subject to the conditions and limitations stated in this Part and on the Guarantee certificate.

3.1.2. Framework of RoofStar Guarantee

3.1.2.1. Overview
  1. The reach of a RoofStar Guarantee is made possible through a rigorous Quality Assurance and Quality Control program for all roofing, grade-level waterproofing, and vegetated roof assembly projects that (a) specify the Guarantee and (b) are constructed by RCABC contractor Members to meet the material and construction requirements of the Program. The RoofStar Guarantee Program is comprised of five principal requirements that make it successful and an internationally recognized model of how to control and ensure quality.

3.1.2.2. Independent Field Reviews
  1. Highly qualified, fully independent professional roof Observers who know and understand our RoofStar Guarantee Standards provide regular course-of-construction reviews to ensure each project is built with Accepted Materials, by qualified personnel, according to RoofStar Guarantee Standards.
  2. Observers review the performance of the project after the first two years, and again during subsequent years (applicable to the 10 and 15-Year Guarantees) and provide the Owner with reports that detail the project condition and identify maintenance or repair needs, so that Owners can look after their investments.
3.1.2.3. Published Guarantee Standards
  1. Clear, objective, evidence-based Standards guide the design, material selection, and construction of a project intended to qualify for a RoofStar Guarantee.
  2. All Standards are published in the Roofing Practices Manual, which also lists currently accepted materials that qualify for a RoofStar Guarantee.
3.1.2.4. Technically Qualified Installers
  1. A waterproofing roof, Architectural Sheet Metal (ASM) roof, or a waterproofing project at grade, intended to qualify for a RoofStar Guarantee , must be supervised and directed by Active Member employees who are recognized nationally with a Red Seal certificate for their expertise; RCABC policy limits supervisor-to-apprentice and/or labourer ratios, to ensure quality installation from beginning to end .
  2. Vegetated roofs may qualify for a RoofStar Vegetated Roof Guarantee if they are constructed by qualified installers who meet the criteria established in the “RGC Standard for Vegetated Roof Assemblies”.
3.1.2.5. Membership
  1. RCABC Member Contractors commit themselves to provide the best workmanship in the industry, and that commitment is underwritten by demonstrable financial stability, a history of excellence, COR certification (for the best safety on the job), ethical standards, and surety bonds held by the RGC.
3.1.2.6. Accepted Materials
  1. A RoofStar-guaranteed project is built with only pre-qualified, proven materials accepted by the RGC.
  2. All Primary Materials are backed by a material bond presented to the RGC by each RCABC manufacturing member (Ref. Div. A, Article 1.1.2.1.(4) concerning material acceptance).
  3. Only accepted materials are listed in the Manual; materials that are not listed do not qualify for a RoofStar Guarantee.
