Beyond Metal Panels: Other Critical Parts and Accessories

When you think of a new roof, you probably picture the main material—the shingles, tiles, or metal panels. While these are the most visible parts of a roofing system, they are not the only ones. The durability and efficiency of your roof depend on a variety of other critical parts and accessories working together.

Here’s a breakdown of the key components of your roof that go beyond the main panels.

Sealants and Sealant Tape

Moisture is one of the biggest threats to your home. Water can corrode metal, rot wood, and cause extensive interior damage. Roof sealants are a protective barrier that prevents moisture from penetrating the roof system, ensuring that rain or melting snow can't damage your home's structure.

Sealants come in different forms, each with unique advantages:

❇️ Acrylic sealants are great for pitched roofs and offer strong UV (ultraviolet) protection.

❇️ Silicone sealants provide effective protection against both UV rays and moisture.

❇️ Rubber sealants are known for being easy to apply.

You can also use sealant tape—a thin, moisture-resistant strip—to create a waterproof seal in vulnerable areas like roofing seams.

Fasteners

Fasteners are the small, but critical, pieces of metal that roof contractors use to connect and secure different parts of the roof, including panels, trim, and flashing. Common examples include screws and nails.

Though small, fasteners are essential to your roof's overall performance and longevity. They determine how strong each section is and ensure that wind can't rip off panels. Proper fastening also significantly reduces the risk of leaks.

Clips

Roofing clips (or cleats) are concealed anchors that connect the main roofing material to the underlying deck. They are a crucial part of a metal roofing system, as they allow for the natural expansion and contraction of the panels caused by temperature changes.

The two most common types are:

🔗 Floating clips are used for long metal panels and in areas with extreme temperature changes. They allow the panels to slide, accommodating expansion and contraction without damaging the roof.

🔗 Fixed clips are suitable for shorter panels and in areas with more moderate temperature fluctuations. They do not allow for movement.

Your roofing professional will help you choose the right type of clips for your specific roof.

Underlayment

The roofing underlayment is a layer of material that sits between the roof deck and the final roofing material. While it’s invisible on a finished roof, it provides a vital, secondary barrier against water penetration.

Underlayment is typically made of synthetic, felt, or rubberized asphalt. While felt is affordable, synthetic and rubberized options offer superior, long-lasting protection.

Trim and Flashing

A well-designed roof is all about keeping water out. Trim and flashing are installed to seal joints and protect vulnerable areas from water.

❇️ Trim seals the joints where different roof sections meet, such as at the ridgeline.

❇️ Flashing protects the joints between the roof surface and other structures, like chimneys, skylights, and vents.
