What The Streaks Actually Are

Those Black Streaks Are Alive

The dark streaking running down your roof is Gloeocapsa Magma, a blue green algae that feeds on the limestone filler in asphalt shingles. It holds moisture against the roof, adds heat load in summer, and shortens the life of the shingle it is eating.

Pressure washing a roof strips granules and voids most manufacturer warranties. Soft washing applies a cleaning solution that kills the organism, then rinses at low pressure. The roof keeps getting cleaner for weeks afterward as rain carries the dead growth off.

Why It Matters

What A Dirty Roof Costs You

Roof cleaning is cheaper than a roof, and the difference from the curb is dramatic.

Shingle Life

Algae and moss hold moisture against the shingle and eat the filler. Removing them stops the damage instead of waiting for a replacement quote.

Energy & Heat

Dark streaking absorbs heat your light colored shingles were designed to reflect, which the attic and the air conditioner both feel in July.

Resale & Curb Appeal

A streaked roof reads as a worn out roof to buyers and appraisers. Cleaning it is one of the cheapest moves before a listing photo shoot.

Done Safely

We Stay Off Your Roof Where We Can

Most of our roof work is done from ladders and the ground with soft wash equipment, because walking a roof damages shingles and puts people at risk. Steep or complex roofs get the reach they need rather than a shortcut.

Landscaping along the drip line and any plantings below downspouts get soaked before and after, and gutters get flushed of the debris that comes down during the rinse.

  • Warranty safe method
  • Landscaping protected
  • Gutters flushed after

Inspect

We look at the pitch, the shingle condition, and where the growth is worst.

2

Protect

3

Soft Wash

Solution applied at low pressure and given time to kill the algae and moss.

4

Rinse & Flush

Roof rinsed, gutters flushed, landscaping soaked a second time.

Common Questions

Frequently Asked Questions

Not with soft washing. The method uses low pressure and a cleaning solution rather than force, so granules stay where they belong. Pressure washing a roof does cause damage, which is why we do not use it on any roof.

No. Soft washing is the method shingle manufacturers and the roofing industry recommend for algae removal. High pressure washing is what typically voids a warranty.

Most of the change shows the same day, and the roof keeps improving for several weeks as rain rinses away the dead growth. Heavy moss and lichen take the longest to release.

Every three to five years for most homes in this area. Roofs shaded by mature trees or facing north often need it sooner, since those slopes stay damp long enough for algae to take hold.

Yes, with proper prep. We saturate landscaping before and after so any runoff is heavily diluted. Plants directly below downspouts get extra attention since that is where rinse water concentrates.

We flush the gutters as part of the roof rinse so debris from the wash does not sit in them. A full gutter cleaning is a separate service and costs less when booked in the same visit.
