Benefits of Pressure Washing

✔ Stops Mold & Algae Growth and Extend Roof Lifespan Moss traps water against your shingles, causing them to crack, curl, and decay. Removing the moss protects your roof and adds years to its life. That moisture also encourages mold, mildew, and algae to grow exponentially. Removing the moss helps maintain a healthier home environment.

✔ Prevents Costly Repairs Unchecked moss growth leads to leaks, water intrusion, and even structural damage. Routine moss treatments helps you avoid expensive repairs down the road.

✔ Backed by a Professional Guarantee A reputable soft washing company stands behind its work with a warranty or satisfaction guarantee. This gives homeowners confidence that if organic growth like algae or moss comes back within a set period, it will be treated again at no extra cost. Professional warranties show that the company uses proven cleaning methods, safe solutions, and is committed to lasting results.

Why Regular Roof Cleaning Matters

In Portland’s damp climate, moss grows quickly and can take over a roof in just one season. While a one-time cleaning removes existing moss, without follow-up treatments the growth will always return. Regular moss treatments are essential because they stop new spores from taking root, keeping your roof clean and protected year-round.

Our Pressure Washing Process

1. Inspection & Pre-Treatment – We assess the concrete’s condition and apply a powerful, eco-friendly cleaning solution to loosen stains and buildup.

2. Preparation & Protection - We cover landscaping, direct runoff away from sensitive areas, and ensure your property is protected during the cleaning process.

3. Debris Removal - Loose debris such as branches, leaves, and heavy moss clumps are carefully removed by hand or with low-pressure tools.

4. Soft Wash Application - Instead of using high pressure that can damage shingles, we apply a specialized soft wash solution that kills moss, algae, and lichen at the root. This ensures a longer-lasting clean.

5. Final Rinse & Clean-Up - After the treatment has time to work, we rinse away any remaining residue and perform a full clean-up, leaving your roof and surrounding areas spotless.

Why Roof Washing Is Important for Homeowners in Portland, OR

Portland’s wet climate and abundance of trees make moss, algae, and lichen a common problem for residential roofs. While a little moss may seem harmless, over time it traps moisture against shingles, causes decay, and can significantly shorten the lifespan of your roof. That’s why professional roof washing in Portland, Oregon is an essential part of home maintenance.

Hector of Blue Diamond Soft Wash was fantastic! Delivered an honest, reliable quote & service. Cleaned my gutters, removed moss from the roof, and applied a coat of zinc. Hector also found some pops on roof and applied a sealant to the nails. I would certainly recommend his service and will use again. Photos attached.
