Those black streaks are algae, and we remove them the safe way, with a low-pressure soft wash that protects your shingles.
If you have dark streaks running down your roof, you are looking at algae that thrives in North Texas humidity. It feeds on the limestone filler in asphalt shingles, which is why it spreads across so many homes in the metroplex, and why it comes back if it is only rinsed off.
A roof should never be blasted with a pressure washer. High pressure strips the protective granules off your shingles and can void your warranty. We use a low-pressure soft wash with a treatment that kills the algae at the root, so the streaks lift away and stay gone far longer than a rinse would manage.
Roof cleaning is where the wrong approach does the most expensive damage. Walking and blasting a roof shortens its life. Our low-pressure method cleans the surface while protecting the shingle, which is how you get a clean roof and keep the years of service you paid for.
We serve Plano, Frisco, McKinney, Allen, Southlake, and the surrounding North Texas communities.
