Midwest Improvement Service is a dual certified roof cleaner in Ohio. We are certified by the RCIA (Roof Cleaning Institute of America) and A-R-C-A (American Roof Cleaners Association). We can erase the black streaks and kill the algae!! Our roof cleaning method uses NO PRESSURE equipment. Pressure washing will remove granules from the shingles. We will not use Sodium Hydroxide as this chemical will eat away at the tar in the shingle. We only use the cleaning agent approved by ARMA (Asphalt Roofing Manufacturers Association).
