Williams Home Improvement | Roofing Services in Cottrellville, MI 48039

We start by inspecting your entire gutter and roofing system to identify the root cause, which is often clogging, improper slope, or undersized gutters for our area's rainfall. Our solution includes thorough cleaning, precise re-sloping for optimal water flow, and if needed, installing larger-capacity gutters or adding downspouts to effectively channel water away from your home's foundation, preventing damage.

Those black streaks are Gloeocapsa magma algae, common in our humid Michigan climate. We don't just power wash, which can damage shingles. Instead, we use a specialized, low-pressure soft wash system with EPA-approved algaecides to safely kill the organism at the root. We can also apply zinc or copper strip treatments during a roof replacement to provide long-term prevention against future stains.

Absolutely. A key advantage of working with us is our full-service capability. If a roofing leak from gutter overflow has led to water intrusion, we can manage the entire project. We'll repair the roof and gutter system, then coordinate any necessary interior repairs like drywall, insulation, or painting—all under one contract, ensuring a seamless and efficient solution for your Cottrellville home.
