Roof ballast must be installed in a good workmanlike manner meeting the requirements of the Ontario Building Code and the design.

One -Year – Work and Materials

Roof ballast not meeting the acceptable condition shall be repaired.

Ballast load, distribution and physical attributes (fines, rounded stone etc.) are usually specified in the design.

Membrane system must be installed in a good workmanlike manner free from damage and shall meet the requirements of the Ontario Building Code and the design.

One -Year – Work and Materials. Two-Year - Building Envelope Water Penetration. Damage resulting from improper maintenance or additions, deletions or alterations made by the homeowner is excluded from the statutory warranty.

Membrane systems not meeting the acceptable condition shall be repaired.

Membrane thickness, number of layers, reinforcing etc. are generally defined by the manufacturer’s specifications if not covered by the design documents. These attributes affect the durability of the system.

Water shall not become trapped under roofing membrane.

One -Year – Work and Materials. Two -Year – Building Envelope Water Penetration

Roofing not meeting the acceptable condition shall be repaired.

Roofs shall allow no water penetration.

One -Year – Ontario Building Code Violations. Two -Year – Building Envelope Water Penetration. * Water leakage resulting from improper maintenance or an act of God is excluded from the statutory warranty.

Defects allowing water penetration through the roof shall be repaired.

Water penetration includes entry into occupied spaces and into concealed areas of the assembly or attic intended by the design to remain dry. Roofs include all components of the roof: shingles, membranes, flashings, drainage systems etc. The owner/Condominium Corporation should take immediate steps to prevent damage to their property and report any losses to their home insurance provider.

Vents, grilles and louvers must be designed and constructed to prevent the entry of rain, snow and insects into the building (unless they are designed to accommodate such penetration and incorporate drainage). Vents, grilles and louvers shall be installed in accordance with the Ontario Building Code.

One -Year – Ontario Building Code Violations. Two -Year – Building Envelope Water Penetration. Water penetration resulting from improper maintenance or an act of God is excluded from the statutory warranty

Defective material or improper installation resulting in water penetration into the building shall be repaired.

Under some conditions, slight amounts of precipitation may be driven into roof vents, grilles and louvers and may subsequently dry without causing damage. This condition is warranted only where there is a demonstrated defect in work or materials supplied by the builder that result in water damage or ponding.

Attics should be provided with sufficient ventilation (if designed to include ventilation), air sealing and thermal insulation, and roofs should have adequate eaves protection to minimize ice damming and icicle formation.

One-Year - Work and Materials

Where icicle or ice damming development can be related to a defect in the attic ventilation, eaves protection, thermal insulation, and air leakage from the interior or other workmanship-related concerns, the defects shall be corrected to minimize ice build-up.

Icicle formation can pose a hazard to building users. Some regions are more susceptible to icicle formation than others. Where water, snow or ice can accumulate on a building, provision shall be made to minimize the likelihood of hazardous conditions arising from such accumulation.

Efflorescence commonly occurs on masonry and of itself is normal and not warranted. Concentrations of efflorescence that persist over time may indicate an underlying concern that may have warranty coverage.

One-Year-Work and Materials

If it is determined that a defect in work or material is the cause of the efflorescence, repairs to the defect shall be made.

Efflorescence is the formation of a white crystalline deposit on the surface of concrete and masonry when moisture evaporates from the surface. It is an indication that moisture is moving through the material to the surface.

Drip edges shall shed water away from adjacent cladding elements and shall not concentrate water run-off onto the cladding unless so intended by the design.

One-Year - Work and Materials

Where drip edges are provided, they must be effective

Window and door sills and related flashings designed to control surface water shall not collect water.

One-Year - Work and Materials

Window sills and flashings not meeting the acceptable performance shall be corrected.
