In British Columbia, a metal roof typically lasts significantly longer than asphalt shingles, offering a much higher lifecycle.
Based on the comparative data:
- Metal roofs have an average lifespan of 40 to 70 years.
- Asphalt shingles generally last between 15 and 30 years, with some installations on the Lower Mainland seeing a shorter life of 15 to 25 years due to consistent moisture and UV exposure.
This means a metal roof can last two to three times longer than a traditional asphalt shingle roof. While the residential metal roof cost per square foot is higher upfront, the longer replacement cycle often results in a lower total lifecycle cost because homeowners avoid the frequent replacements required by asphalt systems.
