Cosier Roofing | Roofing Services in Boyne City, MI 49712

In Boyne City, underlayment often fails due to moisture intrusion and ice dam pressure. We conduct a detailed inspection to locate compromised areas. Our repair process involves carefully removing affected shingles, replacing the damaged underlayment with high-quality, ice-and-water shield materials specifically rated for our climate, and reinstalling the roofing with proper sealing to prevent future leaks and protect your roof deck.

Our local weather, with its freeze-thaw cycles and lake-effect precipitation, accelerates rust on standard metal flashings. We inspect all flashings—around chimneys, vents, and valleys—for corrosion. We replace rusted sections with durable, corrosion-resistant materials like galvanized steel or aluminum, ensuring a proper seal and overlap. This prevents water from seeping behind the flashing, which is a primary cause of interior water damage in area homes.

Key local signs include water stains on interior ceilings or walls, especially after heavy rain or snowmelt, granules from shingles in your gutters indicating wear, and visible rust streaks or gaps at roof penetrations. If you notice any of these, it's wise to get a professional assessment. We offer free, no-obligation inspections to identify if the issue is with the underlayment, flashing, or both, and provide a clear explanation and quote.
