FACTSHEET

The manufacturer may not warranty your shingles if proper maintenance is not kept up or

pressure washed.

The diminished value by algae growth could affect any needed insurance claims due to lack of

due care. In other words if your shingles are already degraded by lack of maintenance this

could be used to minimize your claim. Many insurance companies are now excluding (or at

least limiting) coverage for molds, check your individual policy or contact your agent. Some

insurance companies are cancelling policy's for "excessive growth" on roofs, we have a letter

from one very large insurance agency on file explaining this issue.

The algae infestation on your roof  could be a cause of health problems for allergy sensitive or

the elderly. Here is an article written by : Dr. Morgenroth

Dr. Morgenroth is a semi-retired, adjunct professor of neurology at UM.  He was a principal

administrator in the Environment Health and Safety Division of the Organization for Economic

Cooperation and Development (OECD) for 20 years; prior to that he was a Group Leader in the

Toxicology Division at the Center for Food Safety and Nutrition in the US Food and Drug Administration

(FDA).

It is cost effective to clean and maintain your roof system. Why should you pay TWICE for a 30

year roof system. With the growth of algae on your roof, it can shorten a 30 year shingle into a

15 year shingle. This can be prevented by maintaining your roof  only 3-4  times in 30 years. It

is cost effective and can save thousands of your hard earned dollars !! 

Many roofers may claim that you need your roof to be replaced, while that might be true

depending on the age or other mitigating factors. We will NEVER clean a roof that needs a

TRUE replacement. We can advise you based on our 28 years of experience in roof systems,

if your roof is in dire need of a cleaning or replacing.
