Anatomy of a High-Performance Metal Roof

A high-performance metal roof is much more than the durable, attractive panels you see from the street; it’s a complete system of components working in harmony. The quality of these often-unseen parts is what truly determines how well your roof will stand up to the Ohio Valley's demanding four-season climate.

Let's look at some of the critical components that make up a professional metal roofing system.

Sealants and Tapes

Think of sealant as the gasket that makes your roof watertight, creating a flexible barrier against moisture. In our climate, it must endure both the intense summer sun and freezing winter temperatures without failing. We select high-quality sealants and tapes specifically designed to waterproof vulnerable seams and seal around vents and pipes.

Fasteners

Metal naturally expands in the summer heat and contracts in the winter cold. Roofing clips are engineered anchors that hold the panels securely to the roof deck while allowing for this thermal movement. This prevents the metal from buckling or warping, which is essential for a long service life in Ohio.

Clips

Metal expands in the summer heat and contracts in the winter cold. Roofing clips are smart little anchors that hold the panels firmly to the roof deck while still giving them room to "breathe" with these temperature changes. This prevents the metal from buckling or warping, which is essential for a long, trouble-free lifespan in Illinois.

Underlayment

Directly beneath the metal panels is a crucial layer of high-temperature underlayment. This is your roof's second line of defense. This waterproof membrane protects your home's wooden structure from any moisture and is especially important for preventing leaks caused by ice dams during our cold winters.

Trim and Flashing

Trim and flashing are the custom-fabricated metal pieces that seal every joint, edge, and angle on your roof. Flashing is installed anywhere the roof meets a wall, chimney, or skylight—the areas most prone to leaks. Meticulous flashing work is the signature of a true professional installation.
