PERFORMANCE GUIDELINES: 5. ROOFS

5.11 Shingle Edges Are Curled or Cupped

Acceptable Performance/Condition

The primary role of roofing is to protect the building from the weather.

Asphalt shingle edges and corners need not be completely flat in order to perform their function. However, edges and corners that curl or cup to expose the uncoloured portion of the shingle below are not acceptable.

Adequate attic ventilation is necessary to prevent excessive solar heat build-up in the attic that can contribute to curling and cupping.

Warranty Coverage

• 12 months In-Home
• 15 months Common Property

Damage resulting from normal wear and tear is not covered under warranty.

Claim Response

Asphalt shingles not meeting the Acceptable Performance/Condition must be rectified.

Where repairs are required, colour, finish or texture may not have an exact match.

Seasonal conditions may delay the timing of repairs.

Maintenance Tip

Ensure attic vents are not blocked as part of regular maintenance.
