Moss Removal

Moss might seem harmless at first, but if left untreated, it can lead to serious roofing issues:

• Moisture retention: Moss holds water against your roof, increasing the risk of leaks and rot
• Shingle damage: As moss spreads, it can lift shingles and allow water to seep underneath
• Structural problems: Prolonged moisture can weaken the roof deck and lead to mold or wood rot
• Curb appeal: Moss makes even a well-built roof look neglected

The sooner you remove moss, the better chance you have of avoiding long-term damage and expensive roof repairs.

We treat every roof based on its specific material. Here’s how we approach moss removal across different systems:

• Asphalt shingles: Asphalt shingles are vulnerable to moss damage, especially at the edges and in shaded areas. We carefully remove moss using soft brushes to avoid dislodging granules and apply a treatment to prevent future growth.
• CCA Pressure-Treated Wood: While CCA-treated wood resists some moisture, it is still prone to moss buildup. We gently clean the surface and recommend periodic inspections to prevent long-term damage.
• Cedar Roofing: Cedar shakes and shingles are porous, which means moss can take hold deep in the grain. We use a low-impact removal method to avoid cracking the wood and apply a treatment that’s safe for cedar.
• Western Red Cedar Shakes & Shingles: This premium cedar product needs special care. We use only non-abrasive tools and a cedar-safe formula to clean and preserve the wood’s natural beauty while preventing moss regrowth.
• Fibreglass Roofing: Moss can degrade the top layer of fibreglass shingles over time. We remove buildup manually and apply a roof-safe moss inhibitor to extend your roof’s life.
• Metal Roofing: While moss doesn’t damage metal roof the same way, it can cause moisture pooling and rust at seams or fasteners. We clear moss thoroughly and check for areas where water may collect.
• Torch-On Roofing: Flat torch-on roofs can be especially vulnerable to moss due to poor drainage. We carefully remove moss without compromising the membrane and ensure that water is flowing properly to drains.
