Flashing & Waterproofing

Professional Excellence in Flashing & Waterproofing

Precision flashing is what separates an amateur job from a professional one. We install durable, leak-proof barriers in high-risk areas like valleys and chimneys.

Flashing is the most important part of your roof that you can't easily see from the ground. It is the metal infrastructure that directs water away from transitions—valleys, chimneys, dormers, and walls. Most roof leaks don't start in the field of shingles; they start where the roof meets something else. At Eddy Exteriors, we treat flashing as a critical engineering component. We never 'reuse' old, corroded flashing or rely on roofing cement to hide a poor fit. Every project involves custom-bent, heavy-gauge aluminum flashing designed to create a mechanical barrier against water. We use 'step-flashing' along walls to ensure every layer of shingle is protected, and wide-profile valley metal to handle heavy rain runoff. In the cold climate of Fowlerville and Brighton, we also apply a redundant layer of Ice and Water shield behind every piece of flashing. This 'Belt-and-Suspenders' approach means that even if wind drives rain horizontally, your home's most vulnerable points remain perfectly dry. We pay special attention to 'kick-out' flashing—a small but vital piece of metal that prevents water from running behind your siding and causing hidden structural rot.
