Hartford Walter | Roofing Services in Pontiac, MI 48340

In Pontiac, roof deck rot often starts from trapped moisture due to old or damaged shingles and flashing. We start with a thorough inspection, sometimes using moisture meters to find hidden wet areas. We then remove the affected section of shingles, cut out and replace the rotted plywood or OSB decking, and ensure proper ventilation is in place before re-shingling. This stops the rot from spreading and restores the structural integrity of your roof.

Michigan's freeze-thaw cycles and road salt in the air can accelerate flashing corrosion, especially around chimneys, vents, and valleys. Corroded flashing fails to seal, leading to leaks and deck rot. We don't just patch it; we remove the old, compromised metal, clean and prepare the area, and install new, high-quality flashing—often using more durable materials like copper or coated aluminum—sealed correctly to create a long-lasting watertight barrier.

Keep an eye out for interior signs like water stains on ceilings or walls, especially after heavy rain or snow melt. Externally, look for cracked or curling shingles, rust stains running down your siding from flashing, or a spongy feeling when walking on the roof (indicating soft decking). In our climate, these problems won't fix themselves. If you notice any of these signs, a professional inspection from a local roofer like us can catch small issues before they become major, costly repairs.
