Questions, answered
What to know about roof cleaning.
Your roof type and home size are enough to start your online ballpark.
Is roof cleaning safe for shingles?
NW ProKleen uses a low-pressure soft-wash process for roof surfaces rather than the aggressive force used on durable concrete. Its cleaning solution is described as biodegradable and phosphate-free.
What causes black streaks on a roof?
Dark streaks are commonly associated with organic growth that thrives in damp conditions. Professional cleaning improves the roof's appearance and removes that buildup.
How often should a roof be cleaned?
Timing depends on rain, shade, moss, algae, and year-round organic buildup, nearby trees, and how quickly buildup returns. NW ProKleen can recommend a practical schedule after reviewing your property.
Can I review licensing and insurance before booking?
Contact NW ProKleen to confirm current licensing and insurance details before service is scheduled.
Do I need to be home for the on-site estimate?
In most cases, the team can verify your online quote and arrange service without requiring you to take time off. Any property-specific access needs will be confirmed in advance.
How do I get a quote?
Answer a few quick questions online and see your ballpark price immediately. No phone call or site visit is required to get started.
Can I save by combining services?
Yes. NW ProKleen's current multi-service offer saves $100 when eligible exterior services are booked together. The team confirms eligibility with your final scope.
