Mold can form on roof shingles that are in permanent shade and can damage the roof if left unattended. Extensive mold growth can also expose the interior of your attic to mold spores. You can quickly address the problem by contacting an expert in roofing and exteriors in St Louis, or you can also clean the mold off yourself.
Here are some steps to remove mold from your roof.
Protect Your Lawn and Plants – Cover plants with tarps or plastic sheeting to protect them from getting splashed with bleach. Make sure that you cover a wide radius around your home to be safe.
Make and Apply the Bleach Solution – Using rubber gloves and a mask, make a cleanser composed of 1/4 chlorine bleach and 3/4 water in a large bucket. Add one tablespoon of trisodium phosphate (TSP) and mix well. You don’t need specialized roofing and exteriors equipment. Just fill a handheld pump sprayer with the solution, and apply it only to the moldy shingles.
Rinse Well – Allow the solution to sit for at least 15 minutes. Next, rinse the shingles thoroughly with a garden hose at low pressure. Start from the top shingle and rinse downward to prevent water seepage. If any mold remains, apply the cleanser again, wait ten more minutes, and rinse again.
