Roof Soft Washing — Eagle Pressure Washing

ALGAE & BLACK-STREAK CLEANING

Roof Soft Washing — Kill the Black Streaks, Keep the Shingles

The black streaks running down so many DMV roofs are not dirt and not failing shingles — they are a bacteria, Gloeocapsa magma, feeding on the limestone in the shingles, with algae and moss following behind. Eagle Pressure Washing treats roofs the only safe way: a true soft wash. Cleaning solution is applied at near-garden-hose pressure, does its work chemically, and rinses away — no pressure wand ever touches your shingles.

This is a cleaning service, and an important one: the organisms shortening your roof's life are removed and their roots killed, which is why a soft-washed roof stays clean for years instead of months. High-pressure roof washing voids warranties and strips the granules that protect shingles — we simply never do it.

The Treatment at Work

Soft wash solution doing what pressure never should — killing roof growth at the root, at near-zero pressure.

How It Works

Assess from the ground

We evaluate the roof's material, pitch and growth level, and confirm soft wash is the right treatment — no one walks the roof unnecessarily.

Protect the property

Plants and landscaping are pre-wet and covered; gutters are checked so treatment flows where it should.

Apply the soft wash

The cleaning solution is sprayed on at low pressure and left to dwell, killing bacteria, algae and moss at the root.

Rinse & document

A gentle rinse clears the residue. Dead moss releases over the following weeks of rain, and we photograph the result for you.

Roof Soft Washing — Questions

Is soft washing safe for my shingles and warranty?

Yes — it is the method shingle manufacturers themselves recommend. No high pressure is used, no granules are stripped, and the treatment is designed for roofing materials.

How long do the results last?

Most roofs stay clean two to four years, because the treatment kills the organisms at the root rather than just rinsing the surface. Shaded roofs under heavy tree cover may land at the shorter end.

The moss on my roof is thick. Can you still clean it?

Yes. Thick moss is treated and killed first; it then dries, releases and washes away with rain over several weeks. Scraping or blasting live moss off would damage shingles, so we never force it.

Do you fix roofs too, or only clean them?

Only clean them. We remove the growth that makes a roof look old and shortens its life; we never alter the roofing itself. If we spot damage while cleaning, we will point it out honestly so you can call a roofer.
