Older Troy rooflines take a beating from Hudson River humidity and shaded, narrow streets. The black streaks on your shingles are living algae — we kill it at the root with a soft wash, not high pressure.

Roof Washing in Troy
Troy's roofs age faster than most. Between Hudson River humidity, the steep narrow streets that keep sunlight off north-facing slopes for much of the day, and a housing stock where architectural shingles installed 15–25 years ago are still doing the work, the conditions for gloeocapsa magma — the black-streak algae — are close to ideal.
The tell is the same on nearly every block from Washington Park up through Lansingburgh: long dark ribbons running down the north slope of otherwise fine roofs, feeding on the limestone filler in the shingles. Left alone, it drives granule loss, which drives premature roof failure.
The wrong fix is a pressure washer. High pressure will strip the streaks temporarily and take shingle granules straight into your gutters — and void most manufacturer warranties in the process. Our ARMA-approved soft wash uses professional cleaning solutions applied from ladders and the ground. Algae dies on contact. Nobody walks your brittle shingles. And the rooflines stay clean.
Local Conditions
Troy's geography makes it a heavier algae market than the surrounding towns — a river valley humid enough to keep shingles wet longer, plus steep streets and older housing stock that stay in the shade.
Riverfront damp air keeps shingles wet long after storms — ideal algae conditions on any north-facing slope in the city.
Rowhouse streets around Washington Park and downtown block direct sun. Roofs don't fully dry between rains, which accelerates streaking.
Plenty of Troy roofs still carry shingles installed 15–25 years ago and never washed. Prime real estate for algae if never treated.
Washington Park townhouses and downtown buildings often have slate, tin, or standing-seam metal — each requires its own soft-wash approach, never pressure.
Why It Matters
Killing the algae stops granule loss — the biggest single driver of premature shingle failure on Troy's older architectural roofs.
Washington Park and downtown historic roofs get their own soft-wash formulation and technique — never pressure, never walked when brittle.
ARMA-approved. No high pressure, no granules in the gutters, no shingle-warranty language undone.
On shared-wall Troy rowhouses we plan drift, runoff, and gutter flush so the neighbor's roof and gardens aren't affected.
See Us In Action
This is what we do every day across the Capital Region. Real homes, real crews, real results. No stock photos, no gimmicks — just a clean job done right.
Our Process
We photograph the roof from every side, check flashing, drip edge, and shingle condition, and quote firm — no bait-and-switch ranges.
ARMA-approved solution applied at low pressure from ladders and the ground. On most Troy homes nobody walks the roof at all.
Low-pressure rinse, then flush gutters and downspouts — especially important on rowhouse gutters shared with the next-door roof.
