Maintaining a roof in the BC Lower Mainland requires specific strategies to combat the region’s heavy rainfall and diverse microclimates. Key maintenance tips include:

Schedule Bi-Annual Inspections: Professional inspections should be conducted twice a year, ideally after the rainy seasons (Spring and Fall). Regular checks can extend a roof’s life by up to 30 years.

Seasonal Tasks:

• Spring: Focus on cleaning gutters and clearing moss growth.
• Summer: Trim overhanging branches to prevent damage.
• Fall: Inspect roof ridges for signs of wear.

Prioritize Ventilation: Proper attic ventilation is essential to reduce moss growth and algae, which are common in coastal areas. In mountainous zones, ventilation helps prevent ice dams caused by freeze-thaw cycles.

Address Moss Promptly: Moss and algae pose significant risks to materials like cedar shakes and shingles. Clearing moss early is vital to prevent rot and structural damage.

Monitor Regional Factors: For inland areas like Surrey, pay attention to wind resistance, while coastal Vancouver homes should focus on rain-resistant sealants. Regularly check valleys, flashings, and gutters to manage heavy rainfall levels.
