Division A - Scope, Use of Standards, and Guarantee

Part 3 - Guarantee

Section 3.1. RoofStar Guarantee Program

3.1.1. Purpose of RoofStar Guarantee Repair or Replacement Coverage for Materials and Workmanship
  1. The RoofStar Guarantee Program provides depreciation-free repair or replacement coverage for materials and workmanship, for five, ten or fifteen years (the Guarantee Period), up to the limits (Contract Value) stated on the Guarantee Certificate, to rectify leaks through new roofing or grade-level waterproofing system materials.
  2. Coverage is subject to the conditions and limitations stated on the Guarantee Certificate, and as provided below.

3.1.2. Framework of RoofStar Guarantee Overview
  1. The reach of a RoofStar Guarantee is made possible through a rigorous Quality Assurance and Quality Control program for all roofing and grade-level waterproofing 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.

  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. Published Guarantee Standards
  1. Clear, objective, evidence-based standards guide the construction of a project guaranteed by the RCABC Guarantee Corp. (RGC).
  2. All Standards are published in the Roofing Practices Manual, which also lists currently accepted materials that qualify for a RoofStar Guarantee. Technically Qualified Installers
  1. A RoofStar-guaranteed project (currently applicable to only roof waterproofing systems, Architectural Sheet Metal roofs and grade-level waterproofing) must be supervised and directed by Member employees who are recognized nationally with a Red Seal certificate for their expertise.
  2. RCABC policy dictates specific crew-size ratios, to ensure quality installation from beginning to end (Similar personnel requirements for other water-shedding roof guarantees are under development). 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 performance bonds held by the RGC. Accepted Materials
  1. A RoofStar-guaranteed project is built with only pre-qualified, proven materials, and they are backed by Material Bonds collected from our manufacturing members (Ref. Div. A, Article concerning material acceptance).
  2. Only accepted materials are listed in the Manual; materials that are not listed do not qualify for a RoofStar Guarantee.

Section 3.2. Coverage

3.2.1. Terms and Limitations of Coverage Guarantee Terms
  1. Many waterproofing and water-shedding systems qualify for a RoofStar Guarantee, which is available for five (5), ten (10) or fifteen (15) year terms, for commercial, industrial, institutional, multi-family, stratified and residential projects.
  2. Requirements for all guarantee terms are summarized in Part 1, subsection 1.1.2. of the roof system Standards, which can be found in Division B of the RPM. Limitations and Exclusions of Guarantee
  1. Every RoofStar Guarantee is governed by the conditions and limitations on the Guarantee Certificate.
  2. Subject to the conditions and limitations on the Guarantee Certificate, a RoofStar Guarantee pays to repair leaks resulting from
    1. a failure of new materials purchased, supplied, and installed by the Contractor and listed in Division C of the Roofing Practices Manual, inclusive of roof-related linear metal flashings, or
    2. the improper or deficient installation of new materials.
  3. Notwithstanding the specific causes of leaks named on the Guarantee Certificate, a RoofStar Guarantee does not cover leaks resulting from
    1. improper design,
    2. overloading from overburden, amenities, or equipment,
    3. wrinkling, buckling, or movement of a primary material,
    4. water entry from other building components (walls, skylights, etc.),
    5. the failure of a drain or flashing supplied or installed by anyone other than the Contractor,
    6. neglected maintenance of the project,
    7. building air leakage, or the use or absence of air or vapour controls,
    8. modifications to the project made by anyone other than the Contractor, or
    9. changes in building use or occupancy.
  4. A RoofStar Guarantee will not cover or pay for
    1. the quality, installation, or performance of the supporting deck,
    2. drain leaders, which are not considered part of the roof system,
    3. the costs to remove and reinstall irrigation or other services (including, without limitation, electrical and gas services),
    4. replacement (new for old) of any overburden,
    5. damage or leaks caused by the roots of invasive plant species (i.e., certain varieties of bamboo or willow), regardless of measures taken to protect the membrane,
    6. a sacrificial third ply or a coating, used as a walkway or warning zone, which is not considered part of the roof system,
    7. the cost to maintain the roof or its related systems,
    8. redistributing, relocating, or replacing ballast or any overburden displaced by wind, or
    9. thermal loss, howsoever caused.
  5. To facilitate leak investigation and repairs, the RoofStar Guarantee will pay the Contractor for the removal and reinstallation of an overburden but only when the overburden was installed by the Contractor, it is confined to a single, physically defined project areas (no maximum size), and the overburden conforms to the following limitations:
    1. The overburden is an extensive vegetated roof system comprised of trays or other recognized modular methods and is less than 152.4 mm (6”) in depth, exclusive of the plants.
    2. The overburden is unitized (i.e., pavers on pedestals), where each unit does not exceed 1 M2 or 90 Kg (200 lb.).
    3. The overburden is loose gravel (including its associated drainage or protection material materials), and the gravel is less than 150 mm (6”) deep.
    4. The overburden is comprised of structures, furnishings, or planters, but only when they are easily detachable and removable, their detachment and removal does not require the services of a specialized trade (i.e., photovoltaic panels), and each item that must be removed is no heavier than 90 Kg (200 lb).

    In addition to the foregoing limitations and exclusions, the following conditions apply to every project.

  6. Only new materials are permitted in a roof covered by a RoofStar Guarantee; the reuse of existing materials on a project, except as otherwise permitted in a Standard, may void a RoofStar Guarantee.
  7. All materials or products supplied by anyone other than an Associate Member of the RCABC, or which are installed by someone other than the Contractor, will be excluded from coverage under the Guarantee, and may void the Guarantee entirely.
  8. An Integrity Scan
    1. must be performed by an RGC-recognized service provider listed in this Manual,
    2. is required on all waterproofing systems when overburdens, amenities, or equipment are or will be installed on the completed waterproofing system by anyone other than the Contractor, to ensure the waterproofing is leak and damage-free,
    3. is required on all waterproofing systems when overburdens, amenities, or equipment are or will be installed on the completed waterproofing system by the Contractor, but only when
      1. the total project area (footprint), inclusive of planters or other waterproofed features, exceeds 18.58 m2 (200 sf), and
      2. the overburdens, amenities or equipment exceed 150 mm (6”) in depth, and
    4. is not required when the Contractor installs overburden, amenities, or equipment

    2. inspected by an RGC-accepted observer.
  11. The building owner must ensure that the project and its components are properly maintained.

3.2.2. Quality Assurance Overview
  1. Project observations are required as part of the RoofStar Guarantee Program, and these must be conducted by RoofStar-accepted independent Observers (not members of the RCABC) who are employed by RoofStar-accepted firms located and doing business in British Columbia. Each RoofStar Guarantee includes the following work performed by an independent Observer. Course of Construction Reviews
  1. Each RoofStar Guarantee includes the following work performed by an independent Observer
    1. A First Observation that includes an evaluation of the supporting deck surface and its suitability under the RoofStar Guarantee Standards for the project.
    2. Regular observations, on a daily basis when possible or as otherwise mandated by the RoofStar Fee Calculator, during the course of project construction. These observations provide third-party oversight to ensure that the design, materials and application practices conform to the RoofStar Guarantee Standards and RoofStar-accepted Materials.
    3. A Final Observation once the work has been completed by the Contractor.
    4. Written reports that reflect observations and communication during the course of construction, inclusive of recommendations to the Contractor and to the RoofStar Guarantee Program.
    5. A Performance Review conducted at the 2-year anniversary of the project completion date, presented in writing jointly to the building owner and the RoofStar Guarantee Program, and
    6. Subsequent Performance Reviews (for the 10-year RoofStar Guarantee only), conducted at the 5-year and 8-year anniversaries of the project completion date, presented in writing jointly to the building owner and the RoofStar Guarantee Program. Compliance and Performance Reviews
  1. Every RoofStar Guarantee is issued jointly by the member Contractor and the RoofStar Guarantee Program (RGC), once the project has been completed and any significant deficiencies have been addressed by the Contractor.
  2. The Guarantee Period commences on the date of the Final Project Review, and expires on that anniversary five, ten or fifteen years hence, depending upon the Guarantee Period purchased by the owner.
  3. During the first two years of the Guarantee Period, the Contractor is directly responsible for any claims.
  4. Once the two-year Performance Review has been completed, and any outstanding deficiencies have been satisfactorily rectified by the Contractor, the RoofStar Guarantee Program assumes responsibility for the remainder of the Guarantee Period.
  5. Each ten-year (10) and fifteen-year (15) RoofStar Guarantee also includes independent Performance Reviews at specific intervals:
    1. RoofStar 10-Year Guarantee - Performance Reviews at the five (5) and eight (8) year anniversaries of the Guarantee.
    2. RoofStar 15-Year Guarantee - Performance Reviews at the five (5) year, eight (8) year and twelve (12) year anniversaries of the Guarantee.
  6. Performance Reviews are covered by the total cost of the Guarantee; reports from the project Observer provide owners with a detailed portrait of the project, and recommendations for any outstanding maintenance. Claims
  1. Should a leak occur that necessitates a claim, the RoofStar Guarantee Program claims process is simple and responsive, to get repairs done quickly and efficiently, anywhere in British Columbia.
