Do I Need Special Underlayment for a Roof in Port Moody’s Climate?

Yes, Port Moody’s unique environmental demands require specific materials to ensure long-term durability. Due to the city’s high annual rainfall—averaging approximately 1,700 mm—ice and water shield underlayment is code-recommended for homes in this area.

This specialized underlayment is essential for several reasons:

• Rain and Wind Resistance: It provides a critical waterproof barrier against wind-driven rain, which is much more prevalent here than in neighboring cities like Vancouver or Surrey.
• Topography Challenges: Port Moody’s hillside terrain often results in moderate-to-steep roof slopes. These slopes require precise installation techniques and high-performance underlayment to prevent moisture intrusion.
• Climate Protection: The combination of moisture from the Burrard Inlet and local freeze-thaw cycles means that standard synthetic underlayment may not offer enough protection compared to a robust ice and water shield.

We provide thorough roof inspections in Port Moody to evaluate your current system and ensure it meets these local building codes. If you are concerned about your home’s weatherproofing, you can claim your complimentary roof inspection to receive a professional assessment of your roof’s condition.
