Dennis Lozinski Construction | General Contractors & Roofing in Marshall, MN 56258

In Marshall, roof valley leaks are often caused by ice dams, debris buildup, or worn flashing from our seasonal extremes. We fix them by first removing any damaged decking, then installing new, heavy-duty flashing sealed with ice-and-water shield—a critical step for our climate—to create a watertight barrier that directs runoff safely away from the vulnerable valley.

Signs of decking rot include sagging roof lines, spongy areas you can feel from the attic, or visible water stains. Yes, it can and must be repaired to maintain your roof's structure. We carefully remove the affected shingles and plywood, replace the rotted decking with new, treated wood, and ensure the underlayment is properly reinstalled to prevent future moisture issues.

Absolutely. As a full-service contractor, we not only repair the roof but also manage any resulting interior damage. This can include drywall repair, insulation replacement, and repainting of stained ceilings or walls. We coordinate all aspects of the project so you have a single, reliable point of contact from the rooftop down, restoring your home completely.
