Roof Soft Washing — Sullivan County, NY

Those black streaks on most roofs around here are caused by Gloeocapsa magma, an algae that feeds on shingle granules and spreads fastest in shaded, humid conditions. Sullivan County's tree cover and lake-effect humidity make this almost universal on roofs over a few years old. Left alone, it traps moisture against the surface, which leads to rot, shortens shingle life, and can turn a simple cleaning into a roof replacement.
I caught this on a property last season, the homeowner only asked about gutters, but the roof was already showing heavy moss growth. We handled it before it became a bigger problem. That's the kind of thing I flag, every time, whether you asked or not.

Algae and moss trap moisture against the surface. That moisture breaks down the granules that protect your shingles. Remove it now and you add years to the life of your roof. Wait and you're looking at a replacement, not a cleaning.

Black streaks and green moss aren't just cosmetic, but they do make a well-kept property look neglected. A soft wash brings the roof back to what it looked like when it was new.

When I'm on your roof I'm not just cleaning it. I'm looking at it. If something needs attention, cracked flashing, missing granules, areas holding moisture, you hear about it before it turns into a bigger repair.

This is the most common problem on properties in this area. Wooded lots and lake-area humidity create ideal conditions for growth. Left alone it holds moisture against the shingles and shortens roof life significantly. Soft washing removes it without damaging the surface.

Leaves, pollen, and general grime accumulate over time and hold moisture against the surface. A soft wash clears it all and lets the roof breathe the way it's supposed to.

Caused by Gloeocapsa magma, which is an algae that feeds on the limestone filler in asphalt shingles. It spreads fast in humid conditions and gets worse every season you leave it. It's not just ugly, it's actively breaking down your roof.
