Professional roof cleaners in Portland, Oregon typically use a method called “soft washing” to clean roofs. Soft washing involves using a low-pressure spray and a specialized cleaning solution to remove dirt, stains, moss, and algae from the roof.
The process typically starts with clearing off any loose debris and gutter cleaning. Followed by a thorough inspection of the roof to determine the condition of the shingles and identify any potential problem areas. Once the inspection is complete, the roof is then sprayed with a special cleaning solution that is designed to break down and remove dirt, moss, and algae. The solution is then allowed to sit on the roof for a period of time (usually between 10-20 minutes) before it is rinsed off with low-pressure water.
It’s important to note that not all “Professionals” have the knowledge or equipment to Safely & Effectively soft wash a roof. This is why it is vital that you hire a company that is very clear in their process for Roof Cleaning in Portland OR.
