Before and After
UGLY ROOF STAINS
What are those ugly roof stains?
Why do the stains only grow on one side of my roof?
Black algae usually grow on the north side of the home as well as areas under trees. The north side of the home gets the least amount of sun and therefore stays wet the longest. The same is true with the area under trees where there is the most shade and the trees drip rain water keeping the surface wet for longer. The moisture allows the algae to flourish.
Premature roof replacement
Over time, the algae growth can cause your shingles to dry, crack and curl. Leaks will result leading to premature roof replacement. With proper maintenance, your roof should last at least as long as the warranty period.
Higher Energy Costs
Roof Mold and Roof Algae absorb solar heat. Asphalt roof attic temperatures become a lot higher by preventing the reflective capabilities of the granules from doing their job. These soaring attic temperatures make your air conditioner work a lot harder and increase your electric bills, sometimes as much as several hundred dollars a year.
Reduced Home Value
Thinking of selling your home? A dirty roof will cost you thousands! A stained roof covered with Algae causes the potential buyer to make decisions about your home's value and may cause them to assume that the home has further problems on the interior. For home owners, removing roof stains can increase your selling price by thousands of dollars. In many cases, home buyers demand dirty roofs be replaced and that cost ($8,500 on average) comes out of the price for your home.
Potential Cancellation of Homeowners Policy
Your insurance company can inspect your home at anytime and, frequently, it is a drive-by inspection. Condition of the home is noted, including paint, exterior maintenance and ROOF CONDITION.
Insurance Inspectors note the condition of the roof and report back to the insurance company. The insurance company may require that you clean or replace the roof under threat of policy cancellation.
Potential Health Risks
The presence of Algae in such close proximity to a living environment can pose health concerns for those with allergies. The possibility also exists for this Algae to invade the home through exposed areas and cause other health problems.
Do we use chlorine bleach to remove the stains?
Some contractors and home owners do use chlorine bleach to clean their roofs, but it is not advisable. Bleach will clean the surface of the shingle but will not kill the whole algae colony. The stains usually start to reappear within 12 to 18 months. Chlorine will also kill your plants, and is harmful to the environment. We don’t use chlorine.
