Standing Seam Metal Roof Panels by Dimensional Metals, Inc. (DMI)

Dimensional Metals, Inc. (DMI) was established in 1988 by Phil and Steve Gastaldo in the Columbus, Ohio, metropolitan area. The company manufactures high-performance architectural and commercial building envelope systems, such as metal roof and wall panels. Phil and Steve Gastaldo, who operated a family-owned roofing business, became dissatisfied with the manufacturers they purchased panels from, leading to the company's origins. In the mid-1980s, they invested in their first roll former and began producing panels for their use. Recognizing the potential in fabrication, they founded Dimensional Metals in 1988 as a separate entity. In 1996, the Wissman family joined the company as one of several investors. Steve Wissman, the current president's father, was appointed CEO in late 1998 and relocated to the Columbus area to actively manage the business. The company began to experience significant growth with additional funding and operational structure. From 1998 to now, DMI has expanded nearly five times in size. The company now operates from its headquarters in Reynoldsburg, Ohio. The second generation of family ownership and operation, led by JB Wissman, has been instrumental in elevating DMI into a multi-faceted and multi-site metal fabrication firm. DMI offers extensive structural and architectural roof panels, concealed and exposed fastener wall panels, edge metals, and water control systems. DMI's products deliver superior performance, clean lines, and contemporary aesthetics while meeting engineering and design requirements.

For standing seam panels with separate batten strips, we advise against using clamp-on systems. These clamps only attach to the strip, failing to achieve proper torque compared to direct metal-to-metal contact. This lack of torque can result in strip disengagement, causing significant damage and costly repairs. We suggest using adhesive-based polycarbonate snow guards instead. Striated panels may require additional adhesive for proper sealing, as inadequate sealing can trap snowmelt, leading to refreezing and guard detachment. Larger guard options include IceJax II, Snojax II, and SnoBlox Ace, while Deuce and IceJax I offer smaller alternatives. SnowBreaker and SnowBreaker 3M promote safe snow and ice shedding. It's best to avoid using adhesives when mounting on copper roofs to prevent premature corrosion caused by chemical reactions.

Dome & Compound Curve CC10

Dimensional Metals, Inc. offers the Dome & Compound Curve CC10 metal standing seam roof panels engineered for installation on spherical domes or outside corners of curved canopies. These versatile panels come in various material options, including 24 gauge and 22 gauge steel, .032 and .040 gauge aluminum, and 16 oz and 20 oz copper. The choice of material depends on factors such as the desired aesthetic, durability requirements, and project specifications. The CC10 panels feature a snap-together design that simplifies the installation process, making it easier for roofing contractors to complete projects efficiently. The panels incorporate an anti-siphoning seam design to ensure optimal performance and prevent water infiltration. Additionally, the continuous interlocking seam cap helps eliminate the risk of seam disengagement, providing added security and peace of mind. The minimum convex radius for the CC10 panels varies depending on the material. For 24 gauge steel, the minimum convex radius is 3 feet, while for 22 gauge steel, it is 8 feet. For .032 gauge aluminum, the minimum convex radius is 2 feet 6 inches. The material determines the minimum layover radius, the smallest radius at which workers can install the panels on a curved surface. For 24 gauge steel, it is 25 feet; for 22 gauge steel, it is 35 feet; and for .032 gauge aluminum, it is 20 feet. One of the key advantages of the CC10 panels is their ability to be custom-fabricated for specific projects. The panels can fit the unique curves and contours of a building, whether they are concave or convex. This flexibility allows architects and designers to create visually striking and functional roofing solutions that meet the specific requirements of their projects.

The unique rib shape and size of the Batten-Seam BS15 panel restrict the selection of compatible snow guards. Traditional clamp-on individual guards and continuous rail systems are incompatible due to the panel's wide batten seam. Nevertheless, several glue-down snow guard options work effectively with this panel. Larger models such as the IceJax II, Snojax II, and SnoBlox Ace are available, as well as more compact alternatives like the Deuce and IceJax I when snow retention is the goal. For those seeking safer snow and ice management solutions, the SnowBreaker and SnowBreaker 3M are viable choices. These snow guards break the snow and ice into smaller, safer chunks during shedding. When installing snow guards on this panel, it's important to note that extra adhesive may be required to ensure proper sealing, mainly due to the panel's optional striations. This additional glue helps prevent moisture infiltration beneath the snow guard. We do not recommend using adhesive for mounting on copper roofs as it can lead to premature corrosion due to chemical reactions.

**Though DMI treats the Tapered Seam TS as a separate product, it is more accurately a different configuration available for many of the panel profiles in DMI's lineup. While all of these panels are compatible with our glue-down pad-style snow guards (when not curved or radiused), fitment of our clamp-on snow guards and snow rails systems will be based on the individual panel profile that you select and the angle of the taper for the panel. Our clamp-on snow rails, SnoCleat RC, and SnoCleat RCT models utilize the same RCB-3 bracket for installation. With that bracket, they can swivel up to 31 degrees in either direction, but it is up to you to determine if this system will work for your project. Installing aluminum and copper roof panels may necessitate extra snow rail rows to offset their lower strength than steel panels. Avoid mounting snow guards with adhesive on copper roofs, as it can result in early degradation caused by chemical interactions.

Considerations for Adding Snow Guards to Standing Seam Roofs by Dimensional Metals, Inc. (DMI)

Optimizing Color Coordination for Visual Appeal

Match snow retention system colors to enhance your roof's aesthetics. Our ColorBar and SnoCleat offerings feature optional, customizable metal inserts for seamless blending or striking contrasts. For a perfect match, consider optional powder coating services at an extra cost. Customers needing more control over colors or a faster turnaround time can opt to DIY paint or have their system powder coated locally.

Evaluating Snow Load Capacity

Determine your region's "Ground Snow Load" to select an appropriate snow retention system. Most individual pad-style guards can withstand snow loads of up to 45 psf without issues. Areas with heavier snowfall require more robust rail systems. Consult the panel manufacturer if your roof isn't compatible with snow rails and your ground snow load exceeds 45 psf.

Crafting a Comprehensive Layout Strategy

Design a thorough snow retention plan spanning the entire roof length, typically using multiple ascending rows for balanced weight distribution. Arrange individual pad-style snow guards in a staggered pattern. Align snow rails in straight rows. Avoid isolated installations that may overload the system. Utilize our free resources, spacing guides, and custom quote forms to optimize your design.

Prioritizing Standing Seam Roof Protection

Never directly screw snow guards or rails into standing seam metal roofs. This improper technique can cause panel damage, leaks, and costly repairs due to natural expansion and contraction of the panel. Choose clamp-on or adhesive-mounted systems to ensure compatibility and maintain warranty.

Incorporating Ice Management Solutions

Accessorize SnoBar or ColorBar rail systems on standing seam roofs with IceStopper attachments, especially above high-traffic pedestrian areas. You can add these during the initial installation or retrofit them later. Proper spacing is crucial, particularly for seams taller than 1 inch, to prevent ice from slipping beneath the bar.

Timing Adhesive Applications for Optimal Results

Schedule adhesive-mounted polycarbonate snow guard installations for late spring or early summer. The industry-standard Surebond SB-190 adhesive requires about 28 days at 50°F (10°C) for complete curing. Rain resistance develops after approximately 24 hours. SB-190 is unsuitable for copper roofs due to potential chemical interactions leading to premature corrosion.

Validating Compatibility Through Sample Testing

Before installation, verify the compatibility of your chosen snow retention components. Order individual samples or small kits to test-fit snow guards, clamps, brackets, or IceStoppers on your specific roof. This precautionary step can prevent costly mistakes and ensure a perfect fit for your project.
