Types of Metal Roofs We Install

Perhaps the most popular metal roofing system, thru-fastened panels are long-length panels that have concave channels running from the eave to the ridge of the roof. These panels are applied and locked in with gasket screws that go through the panel and into the roof deck. Typical this type of roofing is 5-V, which is used extensively in the Southeastern U.S. Many mountain homes and cabins have used thru-fastened panels since they came to market.

Residential standing seam panels with a flange hidden by the next overlapping panel are growing in popularity throughout the country. The attachment point is covered by the adjacent panel and makes for a very clean looking installation. It does a great job at protecting against all sorts of weather. These panels are steel, aluminum, copper, zinc or terne metal.

With longer length standing seam panels (over 20 feet) concealable moveable clips are attached to the roof deck and the seam of the roof panel. This setup allows the panel to move when thermal expansion and contractions takes place based on the temperates and direct sunlight.

Modular Press-formed granular coated roofs are your standard dimension panels that are either thru-fastened or attached with hidden fasteners and have an acrylic coating with stone granules embedded on the surface of the panel. Shake, tile, and shingle shapes are all made out of 26 gauge steel. The panels may be installed over a batten/counter batten wood grid system or directly to the roof deck itself.

All of the commercial roofing systems listed here on our website are considered “water shedding” systems. The products typically require a roof slope of 3:12 or greater. For each 12 inches of run (eave to ridge) the roof must rise-up at least 3 inches.

On the contrary, there are low-slope “water tight” metal roof systems that can be applied to flatter roofs and many of the MRA manufacturers produce these types of products as well.

Zinc is a natural metallic chemical element and the 24th most abundant element in the Earth’s crust. Compared to aluminum, copper, and steel, it also requires a smaller portion of the energy to convert into usable materials. Architectural zinc is fully recyclable, from building scraps to end-of-use, which lowers the energy use for manufacturing even further.

Zinc creates a protective layer, called zinc hydroxyl-carbonate that blocks out moisture and chemicals from seeping to the zinc beneath it. If that top-most protective layer is ever scratched, or contains small nicks, the hydroxyl-carbonate will reform over time making zinc naturally resistant to corrosion. The flexibility, malleability, and versatility of zinc, combined with its pleasing aspect, make it the material of choice for imaginative building projects, from individual homes to commercial buildings of all sizes, new construction and renovation projects.

Common Misconceptions About Metal Roofing

Noise

Perhaps the most common misconception is that a metal roof will be noisier than other types of roofing. USA RoofMasters can guarantee that this is not true because our metal roods are installed with solid sheathing meaning that your property will actually silence noise from rain, hail and bad weather, many times much better than other roofs.

Lightning

A metal roof will not increase the chances of lightning striking your property. However, if the unlikely did occur, your metal roof would safely disperse the energy throughout the structure. In addition, since metal roofing is not combustible or flammable so there is low risk of any damage occurring to your rood regardless of the weather.

Rust

With a metallic coating of either zinc or a combination of zinc and aluminum it is protected against rust formation. Paint is then applied over the metallic coating to provide the color style desired.

Dents

Weather can wreak havoc on most roofs however metal roofs can withstand decades of abuse from hail, high winds, and heavy snow. Today’s systems also have a 150-mph wind rating (equal to an F2 tornado), meaning your metal roof is safe from high winds.
