    Metal Roofing Explained

    What is Metal Roofing?

    For commercial buildings, metal roofing is one of the most popular commercial roof choices available today.

    And when installed properly - a metal roof can offer decades of long-term performance.

    In fact.

    Some metal roofing systems can last 100 years or longer.

    So what is a metal roof?

    A metal roofing system consists of overlapping metal roofing panels or shingles that are fastened to open framing or a solid substrate.

    While some metal roofs use metal roof shingles...

    In this guide, we will focus on the most common styles of modern commercial metal roofing systems. 

    First, let's take a look at standing seam metal roofs.

    Below is a metal roofing for church with a standing seam metal roof system.

    What is a Standing Seam Metal Roof?

    A standing seam metal roofing system is commonly referred to as a "concealed fastener" roofing system.

    Where the panel seams are fastened to a solid roof deck or open framing using concealed clips or flanges.

    Some standing seam metal roofs utilize a seam cap while others (mechanically seamed panels) utilize an in-field mechanical seamer to create a "double-lock" seam.

    A standing seam metal roof has the following unique design characteristics:

    1. Each standing seam panel includes (on the long sides) a vertical "leg" that joins its adjacent panel to form the "standing seam"
    2. The seam stands above the flat surface of the panel to prevent water entry
    3. Panel fasteners are concealed for a cleaner look
    4. Roof panels are not penetrated by external fasteners

    Standing seam roof panels are available in a wide variety of designs options.

    Designs vary in terms of how seams connect, how the panel is mounted, and the finished look.

    Some standing seam panels include a wide flat surface, while others include striations or ribs in between seams.

    Here are some examples of various standing seam metal roof panels ›

    There are many more options available to accommodate nearly any type of sloped roof.

    From curved roofs to architectural roofs to vertical walls.

    Why choose a standing seam metal roof?

    TPO roofing is one of the most popular types of flat roofs, but a standing seam metal roof is excellent for low or steep slopes.

    Here are a few reasons why people choose a standing seam metal roof:

    1. They are long-lasting and come with long warranties
    2. They look great offering a modern architectural look
    3. Panels can be customized for special roof shapes
    4. They are energy efficient
    5. They can be mounted to a solid substrate or open frame

    Other Styles of Metal Roofing

    The following photos shows a metal roof system utilizing R-panels.

    This system is distinct from standing seam in that it uses sealed exposed fasteners that penetrate each panel to hold it in place.

    Metal Roofing FAQ

    What types of metal are used in commercial metal roofing?

    The most common commercial metal roofing materials are steel or aluminum. Many steel panels are created from galvanized or galvalume steel then coated for color. Some steel panels are left raw to rust for a weathered look. Copper, aluminum, and zinc round out the other primary types of metals used in metal roofing.

    What gauge thickness is metal roofing?

    Metal roof panel thickness traditionally ranges from 29-gauge (0.0135-inch) to 22-gauge (0.0299-inch), with other thicknesses in between - including 26-gauge (0.0179-inch) and 24-gauge (0.0239-inch). Gauge refers to metal thickness, with the lower number representing a thicker metal. Metal thickness of the same gauge varies slightly when comparing steel, galvanized steel, stainless steel and aluminum. For instance, 26-gauge uncoated steel is nominally 0.0179-inch thick, while 26-gauge galvanized uncoated steel is nominally 0.0217-inch thick.

    How long does a commercial metal roof last?

    While quality of materials and installation plays a part in the lifespan of any roof, some commercial metal roofing systems have lasted 100 years or longer. Many modern metal roofs are available with warranties up to 50 years.

    On what types of buildings can you use metal roofing?

    Metal roofing is used on a variety of commercial buildings and residential homes. Common applications include: warehouse, church, school, office building, industrial building, manufacturing plant, shopping center, resort and other hospitality, community building, farm, auto shop, aircraft hangar, brewery, casino, fitness center, and more.

    What insulation is used for a commercial metal roof?

    Open frame commercial buildings will often see vinyl-backed insulation fitted above the roof purlins and below roof metal. Some buildings utilize rigid foam insulation materials.

    How does thermal expansion affect metal roofs?

    According to Berridge Manufacturing, thermal expansion (the expansion of metals upon heating) can account for total movement of 1-inch over a 120-foot long steel roof with a 100-degree swing in temperatures. That means your building will contract in the winter - and at nighttime - and expand in the summer. A well-designed and installed roof system will account for this.

    Can metal roofing be used on a flat roof?

    It is not recommended. Metal roofing systems are recommended for low-sloped to steeply sloped roofs.

    What is a Class A rated roofing system?

    International Building Codes classify fire resistance of various roofing materials. Quality metal roofing systems are rated Class A in accordance with UL 790 standards of testing. Class A is the highest level of fire resistance "effective against severe fire test exposures."

    How does metal roofing hold up under hail?

    Check with your metal roof system supplier to see how their materials are rated for impact resistance. The industry standard test method is UL 2218, which rates the impact resistance of roofing materials from Class 1 to Class 4. Class 4 is the highest rating. The hailstone size required to damage a roof depends on several factors including roof slope, wind speed, and metal thickness.
