Roof Cleaning

This lens has been created to provide comprehensive information about roof cleaning. You'll learn about different roof cleaning products, chemicals, and procedures. Yes, those black stains on your roof can be removed quickly, safely, and without the use of a pressure washer.

The black streaks on your roof are a hardy form of algae that is literally eating your shingles. So it's more than just a cosmetic issue - it's an issue about your roof's health and longevity. Not only that, but the algae inhibits the ability of the shingle granules to do what they are designed to do: reflect sunlight. Thus, the algae can increase temperatures in your attic, which means a harder working air conditioner and a higher monthly energy bill.

It would be wise to hire a professional roof cleaner that offers non-pressure roof cleaning because the work is dangerous and requires specialized equipment, but if you absolutely must do it yourself, stay away from using pressure washers and instead use the non-pressure solutions and methods detailed on the websites listed below. Shingles are not designed to withstand high pressure cleaning and anyone that tells you otherwise doesn't know what they're talking about.
