Precision-Calibrated for Every Surface
At Precision Pro Wash. we deploy a zero-damage soft-wash system. We apply specialized metered treatments precisely calibrated to your roof's surface that safely neutralize moss, lichen, and gloeocapsa magma (black streaks) at the root level without risking damage.
Stucco Siding
Concrete is highly porous, allowing moss and lichen to anchor deeply into the surface. Our systematic soft-wash treatment penetrates these pores to eradicate the growth entirely, preventing root expansion and restoring the tile's exact aesthetic.
​
Fiber Cement Siding
Metal panels demand exact chemical metering to protect the factory paint and finish. Our specialized application safely dissolves algae, organic film, and environmental fallout without risking oxidation or abrasive scratching.
Natural cedar requires an exacting, specialized approach. We deploy metered soft-wash treatments that safely eradicate deep-rooted moss and lichen without splintering the wood or compromising it;s structural integrity.
Wood Siding
Strict Safety & Operational Standards
Exterior property restoration is a high-stakes operation. At Precision Pro Wash, we do not compromise on safety or execution. Our technicians operate under rigorous operational protocols to protect your estate and eliminate your liability. Every deployment begins with a comprehensive site assessment, ensuring we calibrate our commercial-grade proportioning systems and low-pressure soft-wash equipment precisely to your specific siding material. We are a fully licensed and insured entity operating under strict safety guidelines, which translates to zero risk of collateral damage or on-site liabilities for the homeowner.
​
We treat the perimeter of your property with the exact same uncompromising standards. From deploying and securing our high-output pump rigs to strategically managing treatment runoff away from sensitive landscaping, our process is systematic and highly controlled. You are not hiring a casual crew; you are deploying dedicated industry professionals. We execute every phase of the project with flawless precision, guaranteeing a spotless exterior and total peace of mind from our initial arrival to the final inspection.
Our Property Protection Protocol
We take several steps to ensure your property stays safe from exposure to our cleaning solutions. This ensures the health and safety of your plants, pets, and children.
Perimeter Pre-Hydration
Before any treatment begins, we thoroughly saturate all surrounding landscaping, grass, and sensitive surfaces with fresh water. This creates a natural barrier, filling the leaves and root systems with water so they cannot absorb any of our cleaning solutions.
2
Runoff Containment
We do not allow chemicals to dump freely into your yard. We strategically bag, tape, or redirect your gutter downspouts to control the flow of the soft-wash solution, ensuring all runoff is safely routed away from your soil and garden beds.
3
Calibrated Application
We apply our soft-wash solutions using commercial-grade proportioning systems. This allows us to use exact chemical metering at low pressure, completely eliminating dangerous overspray and wind-drift so the treatment hits the targeted organic growth and nothing else.
4
Final Neutralization & Rinse
Once the roof or siding is fully restored, we execute a comprehensive post-rinse of your entire perimeter. We apply a specialized neutralizing agent to instantly neutralize any trace remaining chemicals, guaranteeing the area is completely safe for your plants, pets, and family.

Identifying the Organic Threat
The Mechanical Destroyer
Moss is a highly resilient, primitive plant that acts as a relentless mechanical destroyer by trapping a permanent layer of moisture against your roof. Rather than true roots, it drives microscopic anchoring structures called rhizoids deep into your shingles or concrete tiles, physically prying the materials apart as it swells. During cold Pacific Northwest winters, this trapped water freezes and expands, systematically shattering your roof’s structural armor from the inside out. If left unchecked, this continuous physical weathering degrades your roof's watertight seals and creates direct pathways for costly interior water damage.
The Chemical Weatherer
Lichen is a highly resilient symbiotic organism- a complex partnership between fungi and algae- that act as an aggressive chemical weatherer on your roof. To anchor itself and extract trace minerals, lichen secretes powerful organic acids that actively dissolve the structural binders of your roofing materials. This continuous acidic etching permanently scars the surface, stripping away your roof's protective defenses and leaving the material structurally weekends and highly porous. Once this vital armor is compromised, the degraded surface readily absorbs moisture, accelerating the path to water intrusion and premature roof failure.Â
The Limestone Feeder
Gloeocapsa Magma is a highly adaptable cyanobacteria- frequently misidentified as black mold or simple algae- that creates a dark, UV-protective shield responsible for the heavy black streaks common on modern roofs. This organism actively feeds on the crushed limestone (calcium carbonate) used as a structural filler in your asphalt shingles, slowly depleting the material of it's vital weight and stability. As the bacteria colonizes and darkens the surface, it drastically increases solar heat absorption, leading to thermal shock and the premature degradation of the shingle's essential waterproofing oils. Furthermore, by building up a layer of organic biomass and retaining trace moisture, it acts as the primary pioneer species that prepares the surface for even more destructive moss and lichen to eventually take root.
The Moisture Trap & Catalyst
Roof debris—such as fallen leaves, pine needles, and branches—acts as a physical barrier that fundamentally disrupts your roof's engineered ability to rapidly shed water. As this organic litter accumulates in valleys and along shingles, it creates physical dams that force flowing rainwater to back up and travel laterally beneath your overlapping roofing materials. Furthermore, as this debris decays, it breaks down into a nutrient-rich, acidic biomass that traps a permanent layer of moisture against the roof's surface. This decaying matter not only accelerates the deterioration of your roof's protective layers but also provides the perfect, saturated seedbed required for destructive moss and lichen colonies to rapidly take root.
