The Unseen Parts of a Metal Roof That Really Matter

A great metal roof is more than just the strong, beautiful panels you see from the ground. It’s a complete system of parts working together. The quality of these smaller, unseen components is what truly determines how well your roof will perform and how long it will last, especially here in the Tri-State's demanding four-season climate.

Let’s pull back the curtain on some of the critical parts that make up a professional metal roofing system.

Sealants and Tapes

Think of sealant as the gasket that keeps everything watertight. Its job is to create a durable, flexible barrier that keeps moisture out. In our climate, sealants have to withstand both the intense UV rays of summer and the freezing temperatures of winter without cracking. We select the right type for the job, whether it's for sealing around vents or waterproofing vulnerable seams with high-quality tape.

Fasteners

The screws and clips that hold your roof down are the bolts that hold the whole system together. Using the right type and number of fasteners is critical for the roof's structural integrity. This is what gives a metal roof its incredible resistance to the high winds of a Midwest thunderstorm and prevents panels from lifting over time.

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

Underneath the metal panels is a vital layer of underlayment. Think of it as your roof's second line of defense. This waterproof membrane protects the wood structure of your roof from any moisture that might get past the metal, and it’s especially important for preventing leaks caused by ice dams during our tough winters.

Trim and Flashing

Trim and flashing are the custom-fit pieces that seal all the joints and angles of your roof. Flashing is used wherever the roof meets a wall, a chimney, or a skylight—all the spots that are most vulnerable to leaks. Good flashing work is a hallmark of a professional installation.
