Homeowners across the St. Louis area are beginning to notice black streaks on their roof. Their first thought when they see these stains is they instantly think they need to have their shingles replaced because their shingles are going bad. As the premier roof cleaning St. Louis company, we are here to let St. Louis homeowners know they don’t have to replace their shingles because of St. Louis Roof Stains.

At Marler’s we know you appreciate the curb appeal your home has. We know many homeowners in the St. Louis area have well manicured lawns, beautiful landscaping, and with spring trying to get here, flowers are starting to bloom in the St. Louis area.

But no matter what, those roof stains for St. Louis homeowners are still an eyesore. Many homes in the St. Louis area are affected with this algae that feeds off the limestone in the shingles. Over time, this algae begins to spread across the roof. If you have these stains, you probably noticed some slight shading along your gutter line. Now, slow but sure, these stains are creeping up to the peak of the roof.

With Roof Cleaning St. Louis, we have noticed more and more “companies’ that claim to offer roof cleaning. Many handymen are getting up on the roof with a 3500 psi pressure washer, blasting away at your shingles, cleaning off the algae and stripping the granules off along with it. There is NEVER a need to use a pressure washer on a roof.

At Marler’s, we use a roof cleaning detergent which we apply to your roof using a low pressure pump. This specially designed pump is built for roof cleaning, and never uses more pressure than what a typical garden hose would use. Once your roof is covered in our roof cleaning detergent, we go back with a low pressure rinse and rinse off our St. Louis roof cleaning detergent to remove the stains. Our detergent kills the algae on contact. Once this happens, those black stains you see turn brown. This shows us the algae is dead.

Many so called “St. Louis Roof Cleaning” companies will tell you they will kill the algae, then let the rain wash away the dead algae. Then they want to collect a check on a roof that has brown streaks left on it. At Marler’s we take the time to make sure the roof is cleaned the RIGHT way the first time, and rinse off your roof and surrounding landscaping as well.

We are also one of the only St. Louis Roof Cleaning companies that offer a “18 Month No Mold Guarantee Or Its Free”. Basically we guarantee that your roof will remain algae free for eighteen months. If you see roof stains in this time frame, simply contact us and we will treat that area again for free.
