AB&C Roofing | Roofing Services in Saginaw, MI 48604

In Saginaw, roof deck rot is most often caused by trapped moisture from ice dams, clogged gutters, or minor, undetected leaks that persist over time. We fix it by first locating and repairing the source of the moisture. Then, we carefully remove the damaged sections of the decking (plywood or OSB) and replace them with new, pressure-treated wood. Finally, we ensure proper underlayment and ventilation are installed to prevent future issues, giving you a solid foundation for your new or repaired roof.

A simple re-caulk often fails because skylight leaks in our climate are rarely just a sealant problem. The issue usually lies with the flashing—the metal strips that integrate the skylight with the roof shingles. Over time, flashing can warp, corrode, or become dislodged by Michigan's freeze-thaw cycles. Our repair involves a thorough inspection of the flashing system, proper re-sealing with high-grade materials, and ensuring the surrounding shingles are correctly layered to divert water away, not just a surface-level fix.

Look for interior signs like persistent musty odors, discolored or sagging drywall on ceilings or in attic spaces, and soft spots you can feel when walking in the attic. Exterior clues include cracked or buckling siding near the roofline or visible sagging in the roof plane itself. If you suspect hidden damage, it's crucial to get a professional assessment. We perform thorough inspections that include checking the attic structure and decking integrity to identify any rot or weakness before it becomes a major safety or cost issue.
