Ensuring Optimal Snow Guard Performance on Central States' Standing Seam Roofs
Expert Color Matching
We can match the color of our metal snow retention systems with the color of your roof to create a cohesive, visually appealing appearance. The SnoCleat RC, SnoCleat RCT, and ColorBar Snow Rail System feature interchangeable metal strips that can be matched to your roof's hue, creating a unified look. Customers sometimes use this as a chance to choose a contrasting color to add further visual interest to their roof. You can purchase these strips with the system or craft them on-site using leftover roofing materials. We also offer custom powder coating services, which can blend the system with your roof's color, albeit with the potential for additional lead time and costs.
Compatibility Testing Prevents Costly Mistakes
Before committing to a snow retention system, testing the compatibility of any snow guards, clamps, brackets, or IceStoppers with your project is crucial. Our website allows you to order samples without minimum requirements, including 20" and 27" bar sample kits. This proactive step ensures a proper fit and prevents costly errors.
Optimal Timing for Adhesive-Mounted Guards
While clamp-on snow guards and rails can be installed year-round, adhesive-mounted polycarbonate snow guards require careful timing. The industry-standard adhesive, Surebond SB-190, requires approximately 28 days at 50°F to cure fully. Plan adhesive installations during late spring or early summer for optimal results in the U.S. and Canada. After 24 hours, rain should not pose an issue. We do not recommend using SB-190 on copper roofs due to potential premature corrosion caused by chemical reactions.
Proper Layouts Ensure Effective Performance
The performance of any snow retention system hinges on its layout. Our website offers complimentary guidance, resources, spacing charts, and custom quote request forms. An optimal system should span the entire roof, typically with multiple ascending rows, to evenly distribute weight. Install individual guards in a staggered pattern and mount rails in straight lines. Avoid isolated installations, which can overload the system and lead to failure. If using SnowBreaker, which has different rules for isolated placement, follow our specific installation guidelines.
Consider IceStopper Attachments for Enhanced Protection
For SnoBar or ColorBar rail systems on standing seam roofs, we highly recommend adding IceStopper attachments, especially over walkways, entrances, and parking areas. Install IceStopper attachments initially or retrofit them later. Proper spacing is critical for effectively managing snow and ice buildup. It becomes even more important for seams over 1" tall, as ice can slide under the bar without IceStopper protection.
Know Your Local Snow Load
Knowing your area's ground snow load is crucial when selecting snow retention systems for metal roofs. While most snow retention systems can easily handle up to 45 psf (pounds per square foot) snow loads without issues, heavier snowfall areas require the exclusive use of our more robust snow rail solutions. If your roof panels cannot accommodate rails and the load exceeds 45 psf, consult the manufacturer for their recommended approach. Contact your building inspector or search online for "[your town] ground snow load" to obtain this information about your project.
Avoid Screwing Into Standing Seam Metal Roofs
Installing screw-down snow guards or rails on standing seam metal roofs can lead to disastrous consequences due to the roof's expansion and contraction. This incorrect installation practice risks damaging your panels, causing leaks, costly repairs, and voided warranties. Use clamp-on or adhesive-mounted systems for standing seams to ensure a secure, compatible installation.
