What is the Lifespan of Asphalt Shingles?
In the specific climate of Vancouver and the Lower Mainland, British Columbia, asphalt shingles typically have a lifespan ranging from 15 to 30 years. Most architectural or high-quality installations are expected to last between 20 and 30 years, provided they receive regular maintenance and professional installation.
Several environmental and physical factors can influence this longevity:
- Persistent moisture and UV radiation: Heavy rainfall and sun exposure in the Pacific Northwest can impact durability. Research indicates that field-aged shingles can experience up to a 50 percent reduction in tear strength over time due to weather shocks.
- Installation quality: Subpar installation can potentially halve the expected lifespan of the roof.
- Maintenance: Routine care, such as bi-annual inspections and the removal of moss or algae, can extend the life of the roof by 10 to 15 years.
- Ventilation: Proper attic airflow is essential to prevent moisture buildup and shingle curling, which are common issues in humid BC conditions.
