Roof Washing & Black Streak Removal in Greenwood, SC
Those black streaks running down your shingles are a living algae that feeds on the roof. We remove them with a low-pressure soft wash that cleans the roof without blasting the granules off your shingles.
Why roofs get black streaks
The dark streaks on many Upstate roofs are caused by algae that spreads from roof to roof on the wind. It holds moisture, keeps growing, and makes even a newer roof look old. Moss and lichen can follow, lifting shingle edges over time.
Why we never pressure wash shingles
High pressure strips the protective granules from asphalt shingles and can shorten the life of your roof. A soft wash uses low pressure and a cleaning solution that kills the algae at the root, then lets the rain finish the job. It's the method shingle manufacturers recommend.
What a roof wash covers
- Black streaks and algae on asphalt shingles
- Moss and lichen spots
- Gutters and downspouts rinsed after the wash
- Plants and landscaping protected before and after
Pair it with a house wash
Algae on the roof usually means algae on the siding too. Doing the house wash and roof in the same visit saves a trip and gets the whole exterior clean at once.
Roof washing questions
How long do results last?
A soft-washed roof usually stays clean for a few years, depending on shade and how close the trees are.
Do you walk on the roof?
Only when it's safe. Many roofs can be treated from a ladder or the ground.
Will it hurt my plants?
We wet and protect plants before and after, and rinse thoroughly.
