How Often should Roofs be Inspected in Vancouver?
In Vancouver’s unique maritime climate, the frequency of roof inspections depends on the property type and roofing material. Professional experts generally recommend the following schedules:
For residential properties, bi-annual evaluations are recommended, typically occurring in the spring and fall. These seasonal checks help identify damage from winter ice or summer UV exposure. Because Vancouver receives over 1,200 mm of annual rainfall, it is important to monitor roofs every six months for moss growth and granule loss caused by persistent dampness.
Commercial and multi-family buildings require more frequent attention, with quarterly checks recommended to comply with BC building codes and address higher foot traffic.
Material-specific guidelines include:
- Cedar shake roofs: These are prone to wind damage and moisture rot, benefiting from annual professional reviews and preservative treatments.
- Metal systems: Due to their durability, semi-annual inspections are usually sufficient.
- Asphalt shingles: These should have edges and vents inspected quarterly to ensure proper ventilation.
Following these rhythms can prevent minor leaks from escalating into structural failures and may extend a roof’s lifespan by up to 10 years.
