Roof & Gutter Cleaning

Those black streaks on your shingles are algae, and they get worse every summer. We remove them safely with a low-pressure treatment — never a pressure washer on your roof.

Dark streaks on asphalt shingles are caused by airborne algae that thrives in the Gulf Coast’s heat and humidity. Beyond making a roof look older than it is, the growth holds moisture and can shorten shingle life. The fix isn’t high pressure — that knocks granules loose and can void warranties — it’s a soft-wash roof treatment that kills the growth and lets rain finish the job.

We also clean the outside of gutters, removing the grey and black “tiger stripes” that ordinary rinsing won’t touch, and flush downspouts while we’re up there.

Why we never pressure wash a roof

Asphalt shingles are covered in protective granules. High pressure strips those granules away, shortening the life of the roof and often voiding the manufacturer’s warranty. Soft washing uses solution to do the work instead of force, so your roof comes out clean without the damage.

Commercial roofs and awnings

Storefront awnings, metal roofs and covered walkways collect the same grime and growth. We clean them as part of our commercial pressure washing service and can schedule the work outside of your business hours.

Roof & Gutter Cleaning FAQs

What causes black streaks on my roof?

Most black streaks on asphalt shingles are a type of algae (often called Gloeocapsa magma) that spreads easily in hot, humid climates like ours.

Will roof cleaning damage my shingles?

No. We use a low-pressure soft wash method specifically so we don’t disturb shingle granules. Your roof is treated and rinsed — never blasted.

How long does it take for the streaks to go away?

Most of the staining is gone the same day. Any lingering discoloration typically fades over the next few rains as the dead growth washes away.

Do you clean out gutters too?

Yes. We can clear debris from gutters and flush downspouts, and we brighten the outside faces of the gutters to remove the dark streaking.
