In Lansing, freeze-thaw cycles and heavy snow put immense stress on the sealant and metal around chimney flashing, causing it to crack and separate. We fix this by carefully removing the old, failed flashing, inspecting the underlying structure for water damage, and installing new, code-compliant step flashing integrated with a new counter-flashing and high-grade sealants. This creates a watertight, durable barrier that moves independently from the chimney to prevent future leaks.

A chronic valley leak often points to improper installation or worn-out underlayment. Our best solution is a complete valley rebuild. We strip the area to the decking, install new ice and water shield—a critical step for Michigan winters—and then re-shingle the valley using either the open (metal-lined) or closed (woven shingle) method, chosen based on your roof's pitch and style. This ensures water is safely channeled away, not through, your roof's most vulnerable intersection.

Keep an eye out for key local warning signs. Inside, look for water stains on ceilings or walls, especially near the fireplace (chimney) or where two roof planes meet (valley). Outside, after storms, check for granule loss in gutters, visible rust or cracks in metal flashing, or damaged/missing shingles in the valley itself. If you see any of these, it's time for a professional inspection from a local roofer who understands how our weather accelerates these specific failures.
