Many home owners are not aware of the proper way to clean a shingle roof. Roof stains are a form of algae and need to be treated and eliminated with the proper cleaning solution. There are some contractors that claim to use low pressure with a power washer, stating this is the best way to remove the unattractive stains. Using pressure to clean a shingle roof can remove the granules that are on the surface of the shingles. All shingle manufacturers recommend that you never use a pressure washer because it will void the warranty.
- Use a solution that will eliminate the algae spores
- Never use a pressure washer or any type of surface water cleaner
- Use cleaners approved by shingle manufacturers
- The proper cleaner will remove the stains without pressure
The picture below shows an attachment that hooks up to a pressure washer called a surface disk. This is primarily used to clean concrete. Clearly this method will damage the roof and remove the granules. The algae spores are still alive because water alone will not eliminate it.
