Commercial Roof Washing in Tri-Cities, WA
Protect your commercial roof investment with professional soft wash cleaning. Safe, effective removal of moss, algae, lichen, and organic debris without high-pressure damage.
Protect Your Commercial Roof with Professional Cleaning
A dirty commercial roof isn’t just an eyesore. It’s a liability. Moss, algae, and lichen growth trap moisture against roofing materials, speeding up wear and shortening the life of your roof. Here in the Tri-Cities, seasonal rain and morning dew create ideal conditions for organic growth, and commercial roofs can develop significant buildup in just a few years.
Pure View provides professional commercial roof washing using soft wash techniques that safely remove organic growth, dark streaking, and accumulated debris without damaging your roofing materials. If your building has a flat membrane roof, metal panels, composite shingles, or tile, we pick the right cleaning approach for the material and condition.
Regular roof cleaning doesn’t just improve how the building looks. It can extend the life of your roof by years and help you avoid costly premature replacement.
Our Soft Wash Process
Commercial roof washing takes a fundamentally different approach than pressure washing concrete. High-pressure water can damage shingles, compromise membrane seals, void manufacturer warranties, and drive water underneath roofing materials where it causes hidden damage.
Pure View uses a soft wash process for every commercial roof we clean. Our in-house cleaning solution uses industry-standard, manufacturer-recommended sodium hypochlorite combined with a professional softwashing surfactant. We apply it at low pressure, and it kills moss, algae, lichen, and mold at the root. The solution does the heavy lifting, not water pressure. After the treatment takes effect, organic growth dies off and naturally releases from the roof surface over the following days and weeks.
We protect surrounding landscaping during every roof wash through thorough dilution. We pre-rinse all plants and vegetation with clean water before application, rinse throughout the process, and post-rinse when the job is complete. By the time we finish, the cleaning solution is highly diluted and poses no risk to your property’s vegetation.
For pet safety, we recommend keeping animals inside until all cleaning solutions have fully dried.
Types of Commercial Roofs We Clean
Our crews handle all commercial roof types: tile, asphalt shingles, metal panels, TPO and EPDM membrane roofs, standing seam metal, and concrete or clay tile. We also clean commercial roofs that fall outside typical residential categories, provided the material and conditions are appropriate for soft washing.
Each material calls for different handling, and our team adjusts chemical concentration, dwell time, and rinsing technique based on the specific roof type. Before we start any job, we inspect the roof to identify the material, assess the condition, and confirm the right cleaning approach.
Frequently Asked Questions
Why do roofs in Kennewick need washing?
Over time, organic growth such as black algae, green mold, and moss can build up on roofs in the Tri-Cities area. This growth holds moisture against shingles, which can shorten the life of your roof and make your home look older. Regular roof washing removes this buildup and helps protect your investment.
How does Pure View Exterior Cleaning treat organic growth on roofs?
We use soft washing, a low-pressure method combined with a special cleaning solution that kills organic growth at the root. Unlike high-pressure washing, soft washing is safe for asphalt shingles and does not strip away protective granules. It effectively removes black streaks and green discoloration common in our region.
How often should I have my roof washed?
Most homes benefit from roof washing every one to three years, depending on how much shade and moisture your roof receives. Our technicians can inspect your roof during the visit and recommend the best schedule to keep it clean and extend its lifespan.
