About Our Moss & Algae Treatment Service

Professional roof moss and algae removal and long-term prevention across Massachusetts and Rhode Island. Moss and algae are common on New England roofs, especially on north-facing slopes and under tree cover where shade and moisture promote growth. Left untreated, moss retains moisture against the shingles and causes premature granule loss and shingle deterioration. Roofing Doctor uses safe low-pressure cleaning methods followed by zinc or copper treatment that inhibits future growth. We also install zinc or copper strips at the ridge for ongoing prevention that activates with every rainfall.

What's Included

✓Safe low-pressure cleaning, no pressure washing damage
✓Zinc and copper strip installation for long-term prevention
✓Algae-resistant shingle recommendations available
✓Moss removal from valleys, ridges, and flat areas
✓Treatment effective for 3-5 years per application
