Why Cleaning Your Roof Is Important

Man Pressure Washing Exterior of Home Alpharetta GA

Have you ever driven through a nice Alpharetta, Georgia neighborhood and admired the homes, only to be taken aback by the look of black streaks on roof shingles? These stains commonly occur on shingles and are more than just ugly spots.

Gloeocapsa Magma – The Algae That’s Killing Your Roof

Those dark stains that you see on some shingle roofs are not dirt; they’re actually a robust breed of blue-green algae called Gloeocapsa Magma. Shingles commonly consist of limestone, and Gloeocapsa Magma algae is so powerful that it eats away at the limestone granules, decaying the shingles.

In addition to protecting your roof, shingles are designed to deflect UV rays and help keep your home cool.  When the granules have deteriorated or are covered in algae, your attic can get hotter and your electric bill will rise.

Eventually, you’ll have to get your roof replaced, which as you may know, costs several thousands of dollars.

How To Prevent Premature Aging of Your Roof

To remove these persistent algae, your roof needs to be properly treated by professional roof cleaners. If not, the algae are left to multiply and spread, causing your roof to deteriorate.

Gloeocapsa Magma actually starts off looking invisible and then turns black as it becomes more severe. Therefore, it’s best for you to have a regular cleaning routine as preventative maintenance.
