Isaia's Roofing and Siding | Roofing Services in Lansing, MI 48911

Those black streaks are likely Gloeocapsa magma algae, which thrives in Lansing's humid climate. It feeds on limestone in shingles and can degrade granules over time. Isaia's uses a professional, low-pressure cleaning solution that safely removes the algae without damaging your shingles. We can also apply a zinc or copper-based treatment at the roof ridge to inhibit future growth, protecting your roof's appearance and longevity.

Absolutely. Michigan's harsh freeze-thaw cycles are a leading cause of underlayment failure. Ice dams can force water up under shingles, saturating and rotting the underlayment beneath. Isaia's will conduct a thorough inspection to locate the compromised area. We specialize in precise underlayment repair or replacement, using high-quality, ice-and-water shield materials in critical zones like eaves and valleys to prevent future leaks and protect your home's interior.

For Lansing's climate, focus on durability against temperature swings and moisture. Isaia's recommends impact-resistant shingles rated for Michigan hail, enhanced attic ventilation to combat ice dams, and a premium synthetic underlayment system for superior water protection. We ensure proper installation techniques specific to our region, like securing against high winds, to give you a roof built to last through Michigan's seasons.
