If you've noticed ugly black streaks on your roof in Visalia or the Central Valley, you might be tempted to blast them away with a pressure washer. Stop right there. When it comes to shingle roof cleaning, understanding the difference between soft washing and high pressure washing is the difference between a clean roof and a ruined one.
Why This Service Matters
Those black streaks are actually a form of algae called *Gloeocapsa magma*. This algae feeds on the limestone filler in asphalt shingles, prematurely aging your roof and reducing its ability to reflect heat. Proper roof cleaning eliminates this algae, extending the life of your roof and drastically improving curb appeal.
Common Problems This Solves
- Black Streaks: Algae growth that makes your roof look old and dirty.
- Moss and Lichen: Growths that lift shingles and cause water leaks.
- Energy Inefficiency: Dark, dirty roofs absorb more heat, increasing cooling costs in the Central Valley.
What Property Owners Should Know
Never use high pressure on an asphalt shingle roof. High pressure strips away the protective granules, voiding your warranty and drastically reducing the roof's lifespan. We strictly use soft washing for roof cleaning. Soft washing relies on a specialized, low-pressure application of biodegradable algaecides to gently kill the algae at its root.
Best Time to Schedule This Service
Roof cleaning can be performed year-round in the Central Valley, provided the weather is dry. Addressing algae as soon as you notice black streaks will prevent long-term damage.
Residential and Commercial Uses
Soft washing is the industry standard for both residential homes and commercial buildings with shingle or delicate roofing materials.
Local Considerations in the Central Valley
The Central Valley's warm climate is a breeding ground for roof algae. Our soft wash treatments not only clean the roof but leave behind inhibitors that help delay the return of organic growth.
