What Professional RI Roof Cleaners Do not Want Homeowners To Know

There are certain things that some roofing contractors do not want you to know. If you are thinking about having your roof cleaned there are a few things you should know.  

Most Rhode Island roof cleaning companies provide additional services besides roof cleaning. Most companies use a pressure washing procedure to clean roofs, however, there are other companies that use alternative methods. They do a procedure that is unique to the roof cleaning industry. Some of the companies will give potential customers free information about the alternative procedures they provide. This is one of the best ways to make an informed decision when looking to hire a roof cleaning service.  
Many homeowners are unaware what the black streaks are on their roofs especially roofs that are constructed of asphalt shingle. These black streaks are a type of algae called gloeocapsa magma. Many roof cleaning companies do not know what these black streaks are therefore do not have the knowledge or experience to clean them. Some roof cleaning services will tell you that these black streaks are merely the asphalt showing through the shingles, however, that is not true. They will proceed to tell you that your roof needs replaced not cleaned. The truth is the algae can be removed by having your roof cleaned. The most common procedure involves a low pressure chemical application without a low pressure spray. High pressure sprays will blow off or destroy asphalt shingle granules which will shorten the life of your roof. Over 50% of roofs are replaced due to inexperienced roof cleaning contractors.  
Algae is one of the most common reasons why roofs are cleaned besides mold and mildew. Algae blows through the air and attaches itself to your roof. The algae then feeds on the crushed limestone in asphalt shingles. Rain, snow, and ice continue to feed algae which then flows down the roof causing the black streaks.  
Shingle manufacturers strongly recommended that shingle roofs be cleaned at least twice a year to extend the life of the roof. Having your shingle roof cleaned twice a year ensures that your roof will last for many years to come. It will also save you thousands of dollars by not having your roof replaced.  
So when searching for a roof cleaning company be sure they are experienced in cleaning asphalt shingle roofs and have the knowledge and experience necessary to remove those ugly black streaks caused by algae, moss, mold, and mildew.
