How do I Treat Cedar Shake Roofing for Longevity?

Maintaining the longevity of a cedar shake roof in Vancouver requires a proactive approach to care and professional treatments. With over two decades of local experience, we recommend the following strategies to protect your investment:

• Professional Cleaning and Moss Treatment: Moss and algae thrive in our damp climate, trapping moisture against the wood. We use gentle, low-pressure washing with specialized wood cleaners to kill growth without damaging the delicate cedar fibers. To prevent regrowth, we install zinc or copper strips near the ridge, which release metal ions during rainfall to naturally suppress organic growth.
• Protective Finishing: We apply breathable, semi-transparent oil-based stains. These treatments form a resilient barrier against heavy rainfall and UV rays while allowing moisture to escape the wood, preventing the rot and warping common in the Lower Mainland.
• Debris Management: We advise trimming overhanging branches to minimize shade and reduce debris accumulation. This keeps the roof dry and prevents moisture-related fungal decay.
• Regular Inspections and Repairs: We recommend professional inspections every two to three years to identify early signs of curling, splitting, or insect damage. Promptly replacing damaged shakes and evaluating attic ventilation ensures the system remains weather-tight.
