These roofing panels offer versatility for various snow guard systems. A generous amount of adhesive should be applied to accommodate the panel's unique ribs or striations to ensure proper sealing of glue-down polycarbonate snow guards and prevent moisture infiltration, as inadequate sealing can lead to trapped snowmelt, refreezing, and potential detachment, compromising the system's integrity. Customers seeking larger snow guard options can choose the IceJax II, Snojax II, or SnoBlox Ace systems. At the same time, those preferring a smaller footprint may opt for the Deuce or IceJax I models. The SnowBreaker and SnowBreaker 3M systems promote safer snow and ice shedding. The T-shaped rib design allows compatibility with clamp-on systems like SnoCleat RCT, SnoBar, and ColorBar when paired with the RCB-3 bracket and aluminum RoofClamp RCT attachments. The standard stainless steel SnoBar clamp and RoofClamp RC are incompatible with this rib shape. Although the panel features a mechanically fastened batten cap covering the seam's top, it does not interfere with the clamp-on attachment. Pad-style snow guards are generally unsuitable for curved roofs, requiring a flat surface, so snow rail systems are recommended. If a clamp-on snow rail is incompatible with the curved panel's seams, consulting the roofing manufacturer for recommended methods is advisable. Since aluminum panels are typically less sturdy than steel, installing clamp-on snow rails may require supplementary rows to accommodate the disparity in panel strength, ensuring system stability and longevity.

The bold ribbed profile lends an attractive linear definition to large structures, while the 36-inch wide panels, with 1.75-inch tall ribs, can be obtained in lengths up to 52 feet. Energy efficiency is a hallmark of the Versapanel system. Its high thermal R-values reduce heating and cooling costs, and the thermal break between the face and liner mitigates thermal bridging and drift. The factory-applied panel joint sealant and field-applied sealant work to create an effective air and vapor barrier, further enhancing the system's energy-saving capabilities. Versatility is another key strength of the Versapanel panels. Their lightweight nature allows installation flexibility, with long lengths and various finish options. These panels can be installed in all weather conditions, making them suitable for multiple projects, including warehouses, industrial facilities, schools, and shopping centers.

The Versapanel, while visually appealing, presents particular challenges when selecting compatible snow guards. Its distinct wide-seam design restricts clamp-on individual snow guards like the SnoCleat RC and RCT models and clamp-on snow rails, which cannot function effectively with this panel type. The remaining viable option involves the use of glue-down polycarbonate pad-style snow guards. However, to ensure proper adhesion and prevent moisture infiltration, applying a generous amount of adhesive is crucial to accommodate the panel's unique ribbed surface. Inadequate sealing can lead to trapped snowmelt, subsequent refreezing, and potential detachment, compromising the overall integrity of the snow guard system.

Ensuring Optimal Snow Guard Performance on Centria Standing Seam Roofs

Know Your Local Ground Snowload

Checking how much snow your area typically receives, or your "Ground Snow Load," is vital when picking snow retention systems for metal roofs. Most systems can handle ground snow loads of up to 45 pounds per square foot (psf) without problem. But if your area gets extreme amounts of snow, you'll need beefier snow rail solutions. If your roof panels are incompatible with snow rails and your ground snow load is beyond 45 psf, contact the panel manufacturer for their recommendation. Do a quick search for "[your town] ground snow load" to get the local data for your project.

Time Installing Those Adhesive-Mounted Guards Right

While you can install clamp-on snow guards and rails anytime, adhesive-mounted polycarbonate guards need careful timing. The industry standard adhesive, Surebond SB-190, needs around 28 days at 50°F to cure fully. Plan those adhesive installs for the best results in the U.S. and Canada in late spring or early summer. After 24 hours, rain won't mess it up. However, avoid using SB-190 on copper roofs, which could cause premature corrosion from chemical reactions.

Add IceStoppers for Extra Protection

For standing seam roofs with SnoBar or ColorBar rail systems, adding IceStopper attachments is a smart move—especially over walkways, entrances, and parking areas. You can install them initially or add them later. Proper spacing is crucial for managing snow and ice buildup, even more so for seams over 1" tall since ice can slide under the bar without IceStoppers.

Test for the Perfect Fit

Before locking in a snow retention system, test whether the snow guards, clamps, brackets, or IceStoppers fit your project. We let you order individual samples and kits, like 20" and 27" bar samples, with no minimum order. This step ensures everything fits like a glove and avoids costly mistakes.

Don't Screw Into Standing Seam Roofs

Screwing down snow guards or rails on standing seam metal roofs is a recipe for disaster because of how the roof expands and contracts. This incorrect installation method can damage panels, causing leaks, expensive repairs, and voided warranties. Use clamp-on or adhesive-mounted systems for standing seams to keep things secure and compatible.

Layout for Success

An effective snow retention system spans the entire roof, usually with multiple ascending rows to spread out and distribute the weight evenly. Install individual guards in a staggered pattern and mount rails in straight lines. Avoid isolated installations that can overload the system until it fails. If using SnowBreaker, follow the manufacturer's specific isolated placement guidelines. We offer free guidance, resources, spacing charts, and custom quote request forms so you can nail the layout.

Color Coordinate for Style

For a cohesive, stylish look, you can match the color of our metal snow retention systems to your roof's color. Some systems have interchangeable slide-in metal strips you can match to your roof's color. Some customers use contrasting colors to add visual pop to their roofs. Buy the strips with the system or make them on-site with leftover roofing material. We also offer custom powder coating to blend the system seamlessly with your roof's color for an additional fee.
