McLean Roofing And Siding | Roofing Services in Royal Oak, MI 48067

Black algae stains are common in our humid climate and can't be removed with a simple power wash. We use a specialized, low-pressure cleaning solution that kills the algae at the root without damaging your shingles. More importantly, we can apply a zinc or copper strip treatment at the roof's peak, which releases ions with each rain to prevent future stains, saving you from frequent cleanings.

Moss holds moisture against your roof decking and under shingles, leading to wood rot, leaks, and premature failure. In Royal Oak's shaded neighborhoods, it's a frequent issue. Our process involves careful manual removal to avoid shingle damage, followed by applying a moss-killing treatment. We then address the underlying cause, often by trimming overhanging branches to increase sun exposure and improving attic ventilation to reduce surface moisture.

Prevention starts with a professional roof inspection. We'll check for damaged or missing shingles, assess your gutter system's performance, and evaluate your attic's ventilation. Proper ventilation is key—it regulates temperature and moisture levels in your attic, making the roof surface less hospitable for algae and moss. We can also install preventive treatments during routine maintenance, which is far more cost-effective than dealing with major repairs later.
