McElroy Roofing | Roofing Services in Warren, MI 48089

Warren's humid summers and shaded neighborhoods create the perfect environment for moss, which can lift shingles and trap moisture, leading to rot. We don't just power wash it off (which can damage granules); we perform a safe, manual removal and apply a zinc or copper-based treatment at the roof's ridge to prevent regrowth, protecting your roof's integrity.

Look for reddish-brown stains or flaky metal around chimneys, vents, and roof valleys—common spots where old steel flashing rusts from our wet winters and road salt exposure. We inspect these critical areas, remove compromised flashing, and install new, rust-resistant aluminum or galvanized steel, properly sealed to prevent leaks and ice dam damage.

We recommend a bi-annual inspection, ideally in late spring and early fall. This allows us to check for moss after the damp season and assess flashing before winter. We'll clear debris from valleys, ensure gutters are clear to prevent water backup, and spot early signs of rust or wear, providing affordable repairs that save you from major, costly damage common in our climate.
