S-5! Solutions for Metal Roof Attachment

S-5!® products have a solution for attaching anything to the metal roofs.

Snow Retention S-5! snow retention system offers the most flexible configurations for any metal roofing profiles in the market. Easy to install, durable and safe.

Solar/PV Attachment The new and improved S-5-PV Kit is the perfect marriage for photovoltaic power generation and metal standing seam roofs. With S-5!, you can attach an entire solar array with zero roof penetrations, maintaining the roof's integrity and warranty.

Wind Clamps S-5! application can dramatically improve wind uplift performance. In many cases patented S-5! WindClamps™ can double wind resistance for as little as $0.20 per square foot, preventing multiple modes of failure, including clip disengagement (when used at a clip location).

HVAC/Roof Top Equipment Sometimes, a condensing or similar unit needs to be roof mounted but does not need to duct through the roof — it simply needs a place to sit. How do you mount it so that the panels are unharmed, and anchor it so that it doesn't move? S-5! is the solution. On other occasions, units and ducting can be frame mounted with S-5!.

Pipes/Conduits Attachment Round shapes can also be mounted with S-5!, eliminating unsightly and corrosive wood blocking. Gas piping, electrical conduit, condensate lines—S-5! is the solution.

Signs / Banners Mounting Signs are securely mounted with no wood blocking, no holes in the panels, no leaks — and no problem when the next tenant moves in. Temporary advertising and information banners are easily installed and taken back down with no damage to panels.

Utility Mounting Attach almost any conceivable utility application, including: signs, banners, light fixtures, gas piping, antennas, roof walkways, HVAC equipment, lightning protection systems, condensate lines, stack/flue bracing, fascias, equipment screens, electrical conduit, antennas, cabling, access ladders, and more!

Satellite Dishes / Antennas Mounting Antennas, satellite dishes, lightning protection cabling, even holiday and rooftop lighting can all be mounted quickly and cost-effectively, permanently or temporarily with S-5! attachment solutions.
