Kaden and Bryce did a fantastic job cleaning our roof and gutters. They were professional, friendly, thorough, and went the extra mile to do a great job. I would definitely hire them again.
Bryce did a great job! Had him do the roof, windows and pressure washing the patio, driveway and sidewalks. He cleaned up everything and left it beautiful. We highly recommend and will use him next year!

He did high-quality work and was very professional. We’d definitely hire him again.
Great service! They did roof cleaning including moss treatment and gutters removal. Im very satisfied with their service and I highly recommend them!
Great guys and excellent work. Always ready to help. They did my roof and gutters as well as moving items.
Excellent! Three years of Christmas lights, gutter cleaning and the random exceptionally high fire alarm battery change that needs a ladder no one owns to replace. Always a smile, on time, hard working and accommodating.
We recently hired Bryce to power wash and seal our patio, and we couldn’t be happier with the results! From start to finish, Bryce was the epitome of professionalism—always punctual, incredibly responsive and a true pleasure to work with. He communicated clearly, showed up exactly when he said he would and delivered top-notch work with great attention to detail. Our patio looks amazing and we are already planning to hire him again for future projects. High recommended!!!
Yesterday Kaden and Bryce arrived promptly for a full day of some much needed exterior maintenance on my property. My property has many trees, including some overhang on the roof, which provides much welcome shade. But it also means heavy accumulations of moss and algae! The Anderson team power washed my aggregate driveway, cleaned my roof and gutters, and power washed my large deck, built of ipe wood, which I greatly value. I was absolutely thrilled with their work! Although I was concerned that the cleaning solution might harm the landscaping around the driveway and deck, they assured me that all would be protected, and it was. At the end of the day they cleaned everything before leaving, and although I know they were exhausted, they remained courteous and cordial. For me the Anderson team has definitely found a return client! I plan to hire them to install my exterior holiday lighting this year!
Roof Soft Wash vs. Moss Out Powder
Roof Soft Wash
3 year warranty
Best for:
• Heavy moss buildup
• Homeowners who want the best possible results
How it works:
Soft washing uses a low-pressure liquid solution (typically sodium hypochlorite blended with surfactants) that:
✅ Kills moss, algae, and lichen at the root
✅ Breaks down organic staining
✅ Cleans the roof without damaging shingles
✅ Produces excellent results
Pros
• More dramatic transformation
• Fully kills existing growth
• Safest way to actively clean shingles
• Extends roof life by removing destructive organisms
Cons
• Slightly higher cost
Roof Moss Powder
1 year warranty
Best for:
• Light moss or early growth
• Preventative maintenance
• Homeowners who want more affordable protection
How it works
Powder treatments (usually zinc-based granules) are spread along the roof ridge. When it rains:
🌧️ Zinc slowly washes down the roof
🌱 Prevents moss from regrowing
⏳ Works gradually over weeks or months
Pros
• Excellent preventative solution
• Lower upfront cost
• Helps delay future moss growth
Cons
• It is NOT as strong as soft wash and can struggle with heavily mossy roofs
• It is NOT great against algae leading to faster regrowth
• Roof has to retreated on average every 1-2 years.
Our 4 Step Process:
Step 1:
Roof Inspection – Identify moss severity and shingle type
Step 2:
Moss & Algae Removal – No damaging high pressure
Step 3:
Soft Wash Treatment – Low-pressure, roof-safe cleaning solution
Step 4:
Final Rinse & Cleanup – Protect landscaping and gutters
