Moss & Algae Treatment

Protect Your Cedar Shake Roof from Moss & Algae

Moss, algae, and lichen trap moisture against your cedar shakes, accelerating deterioration. We remove existing growth and apply preventative treatments to keep your roof clean, dry, and lasting longer.

Start with a Moss & Algae Assessment

We inspect your cedar shake roof to assess the extent of moss and algae growth, check for underlying damage caused by trapped moisture, and recommend the right treatment approach for your specific situation.

Preventative treatment options to slow future regrowth

Moisture is cedar shake's biggest enemy

Remove It. Treat It. Protect It.

Untreated moss and algae can shorten the life of your cedar shake roof significantly. Our treatments don't just clean the surface — we address the root cause and apply products that inhibit future growth so you're not back in the same spot a year later.
