Template:Limitations and Exclusions of Guarantee

A RoofStar Guarantee is available for almost any roof design, provided its design and construction conforms to the requirements published in the RGC Standards. Nevertheless, there are limitations and conditions. They are listed on the Guarantee Certificate, and include (without limitation) the following (as they are applicable to the type of project):

1. The RoofStar Guarantee covers leaks resulting from new materials purchased, supplied and installed by the Contractor. All new materials incorporated into a Project intended to qualify for a RoofStar Guarantee must be expressly accepted by the RGC and listed in the Roofing Practices Manual. Accepted Materials include (without limitation)
   1. Primary and Secondary Materials.
   2. penetration flashings and drains.
   3. roof-related linear metal flashings.

   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.

2. Notwithstanding the definition of a waterproofing system or water-shedding system, the RoofStar Guarantee does not cover the quality, installation or performance of the supporting deck.
3. The RoofStar Guarantee (subject to the limitations described herein or stated on the Guarantee certificate) is a guarantee against leaks only, caused only by a failure of new materials installed by the Contractor, or resulting from the Contractor 's installation of new materials.
   
   The term "new materials" includes Primary and Secondary Materials, linear metal flashings, and both penetration flashings and roof drains that have been expressly accepted for use on a project designed and constructed to qualify for a RoofStar Guarantee. Only materials listed in the Accepted Materials Division of the Roofing Practices Manual qualify for a RoofStar Guarantee.
   
   The re-use of any existing material on a project may void the Guarantee.
4. Notwithstanding any of the Guarantee requirements in this Manual, a RoofStar Guarantee will not cover
   1. leaks resulting from
      1. improper design.
      2. overloading.
      3. water entry from other building components (walls, skylights, etc.).
      4. the failure of a drain or flashing supplied or installed by anyone other than the Contractor.
      5. neglected maintenance of the project.
      6. building air leakage, or the use or absence of air or vapour controls.
      7. modifications to the project made by anyone other than the Contractor.
      8. changes in building use or occupancy.
   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 (for example, 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.
5. Overburdens may be installed on a Conventionally Insulated waterproofing system or Protected (“inverted”) Membrane Roof Assembly, but not all designs are suitable for any type, size or depth of overburden (see Part 14 THE ROOF as a PLATFORM). The RGC recommends that a roof supporting overburden be designed and constructed as a Protected Membrane Roof Assembly. The RoofStar Guarantee may be void if a roof is designed and constructed with Overburden that exceeds the capabilities of a Conventionally Insulated waterproofing system.
6. Only a fully adhered membrane may be used in a Protected (“inverted”) Membrane Roof Assembly.
7. An Integrity Scan
   1. must be performed by an RGC-recognized service provider listed in this Manual.
   2. is required on all Waterproofing Systems, to ensure the waterproofing is leak and damage-free, when overburdens, amenities or equipment are or will be installed on the completed Waterproofing System by
      1. anyone other than the Contractor.
      2. 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.
      3. is not required when the Contractor installs overburden, amenities or equipment
         1. equal to or less than 150 mm (6”) in depth.
         2. the total project area (footprint), inclusive of planters or other waterproofed features, is less than 18.58 m2 (200 sf), but the Contractor must nevertheless protect all membrane-covered surfaces (including walls and parapets) with RoofStar-accepted protection materials immediately after the membrane is installed.

8. Electronic Leak Detection is mandatory for grade-level Waterproofing Systems, but optional for roof Waterproofing Systems.
9. Pre-curbs and Concrete Features:
   1. When concrete walls or structures are constructed without a pre-curb, all concrete surfaces must be fully and continuously enveloped with the primary roof membrane.
   2. While the application of non‐penetrating bonded tiling or other architectural finishes to the waterproofing membrane is acceptable for a RoofStar Guarantee, and is subject to approval by the membrane manufacturer, the removal, reinstallation or replacement of any bonded finish, in order to investigate and repair leaks under the terms of the Guarantee, is the responsibility of others.
10. Modifications during the Guarantee Term:
    1. The Guarantor must be notified in writing of any modifications or repairs to the RoofStar-guaranteed project.
    2. The Owner must ensure that any modification or repair work done on the project during the guarantee period is performed to RoofStar Guarantee Standards by a Contractor, and is inspected by a RoofStar-accepted observation firm.
11. Maintenance: the building owner must ensure that the project and its components are properly maintained. Debris in drains, caulking on or around metal flashings, and wind scouring of gravel are considered maintenance issues.
12. Removal and Reinstallation of Overburdens: in order to investigate and repair a leak, the RoofStar Guarantee Program must be allowed to remove overburdens, to expose the membrane. The RoofStar Guarantee pays for the removal and reinstallation of accessible overburdens only (subject to the limits published below), when they are installed by the Contractor, regardless of the project design. The cost to remove, care for and reinstall any overburden that exceeds these limits or conditions, which is inaccessible, or which was supplied or installed by others, will be borne by the building owner.
    1. Maximum coverage area: limited to one physically defined project area (no maximum size)
    2. The RoofStar Guarantee pays for removal and reinstallation of accessible overburdens up to the following limits:
       1. Extensive vegetated roof systems, provided they are comprised of trays or other recognized modular methods and are less than 150 mm (6”) in depth, exclusive of the plants.
       2. other accessible coverings, provided they are unitized (for example, pavers on pedestals) and do not exceed 1 M² or 90 Kg (200 lb.) per unit.
       3. gravel ballast and its associated drainage or protection material components, provided the ballast is less than 150 mm (6”) deep.
       4. structures, furnishings or planters provided each item, or any single component of each item, is easily detachable, does not require a specialty trade, and is no heavier than 90 Kg (200 lb).
