Roof Washing in Albany
Drive down New Scotland Ave, Western Ave, or any leafy street in Delmar and you'll see the same thing: perfectly good roofs streaked with ugly black stains on the north-facing slope. Those aren't dirt. They aren't shadows. They're a living algae — gloeocapsa magma — feeding on the limestone filler in your shingles.
Albany's climate is a gift to this stuff. Humid summers, dense shade through Pine Hills and Buckingham Pond, and rooflines that stay damp for days after a storm. Left alone, the algae eats shingle granules — the #1 cause of premature roof failure.
High pressure will strip the streaks. It will also void your shingle warranty and blast granules into the gutters. Our ARMA-approved soft wash uses professional cleaning solutions that kill the algae on contact, from the ground. No walking on wet shingles. No pressure damage. Streak-free rooflines that stay clean for years.
Local Conditions
Albany sits in a humidity corridor between the Hudson River, the Helderberg Escarpment, and the Adirondack foothills. Combine that with mature tree canopies over most of the city's residential streets, and you've got the perfect breeding ground for roof algae.
Warm, damp summer air keeps shingles wet long after storms — ideal algae conditions.
Pine Hills, Buckingham Pond, and Delmar streets are shaded. Shade + damp = algae growth on north slopes within 3–5 years.
Albany springs and falls are wet and slow-drying — extending the growing window well past summer.
Many Albany homes have architectural shingles installed 10–20 years ago that are prime real estate for algae if never cleaned.
Why It Matters
Killing the algae stops granule loss — the leading cause of premature shingle failure in the Hudson Valley climate.
ARMA-approved soft wash. No high pressure, no walking on wet shingles, no voided warranty.
Bleach-only 'pressure wash' cleans just fade the streaks. Our treatment targets the algae itself, so results hold up far longer than a surface rinse.
A streak-free roofline is a huge win before selling — buyers see 'new roof' when it's really just clean.
