Construction Performance Guidelines
ASPHALT SHINGLES NOT SEALED
Asphalt shingles and self-sealing asphalt shingles shall be secured according to the Building Code.
One-Year - Work and Materials
Shingles not meeting the acceptable condition shall be repaired.
Asphalt shingles installed in temperatures below 5°C will seal when warmer temperatures return. In the short term, unsealed shingles should not affect the weather protection provided by the roof. Where asphalt shingles intersect metal flashing, shingles may not seal. This condition is not a defect in work and materials.
