Attach Virtually Anything to Standing Seam Metal Roof Profiles

Mount snow guards, solar arrays, roof walkways, utilities, HVAC, signs, lightning protection, and more to your standing seam roof with zero penetration.

Why Does S-5! Offer So Many Different Clamps?

Our clamps are specifically designed for your exact standing seam metal roof and roof profile to maximize cost/holding strength ratios. It is important to choose the correct clamp for use on your specific roof type, gauge, and material.

Despite what others may say, a one-size-fits-all clamp compromises either cost or performance.

S-5! clamps are carefully designed to preserve both. This is a defining feature of our approach to metal roof attachments:

We offer convenience in some of our clamps that feature broader diversity, but will also let you know if there is a more cost-effective solution within our product range.
Our goal is to ensure you have the best solution at the lowest cost for your specific application.

Which Engineered Metal Roof Clamp Best Suits Your Application?

S-5! clamps are offered in two sizes to accommodate the holding strength needs of varying utility applications. Our standard (two setscrew) clamps are designed specifically for heavy-duty applications, such as snow retention and provide documented and unsurpassed holding strength. Mini (one setscrew) clamps save considerable cost for medium or lighter-duty applications, such as solar or satellite dish mounting.

Why Use S-5! Standing Seam Metal Roof Clamps?

Verifiable Quality Assurance

Use the threaded holes in the clamp (with provided stainless hardware) to mount solar modules, snow guards, HVAC, satellite dishes, walkways, lightning protection, signage, pipes, conduit, wind uplift enhancements, module-level-power electronics, fall protection and more. All use tools common to the trade with installation so simple, it can be done by a DIY installer.

To ensure the products tested are truly the products sold and shipped, traceability, transparency and certified manufacturing are essential. S-5! only uses certified material, certified testing and certified production in our own ISO 9001:15 manufacturing facility. This process ensures the quality control system performs as advertised.

Our warranties, endorsements, track record and customer service satisfaction validate our claims giving you the confidence that we do it “The Right Way!” Ask us for technical documentation of our QA claims; we are happy to provide it.

What is the S-5! Difference?

Extrusion storage S-5! Manufacturing facility

We Only Use Chemically and Mechanically-Certified Raw Material

Certified quality begins with certified raw material, followed by certified manufacturing and certified testing for holding strength and other product characteristics.

Further, all clamps use non-corrosive materials and are metallurgically-compatible with all common roof materials including titanium-zinc, stainless steel, aluminum, zinc, galvanized steel, Bonderized™ steel, CorTen steel, and 55% AlZn coated steel (Galvalume®, Zincalume®, ZintroAlum®, Zink-Al™).

Clamps are made from high-tensile aluminum (brass for copper roofing). All fasteners and mating hardware are A2-70 stainless steel. S-5! also offers a couple of clamp models available in stainless steel.

What Does “Certified” Really Mean?

Zero Penetration - Maintain Warranties

S-5! invented the technology of utilizing round-point setscrews for a secure mechanical interlock, while protecting the standing seam and any sacrificial coatings, leaving roof warranties intact.

We have conducted ASTM-B117 salt-fog testing to prove that S-5! clamp attachments cause no premature corrosion to the roof panels.

All clamps are designed to outlast the roof using prudent designs, non-corrosive materials and metallurgy.

Clamps utilize Torx setscrews – These screws are resistant to stripping, easy to drive and remove bit during installation. Driver tips are provided with each box of clamps and bits are widely available internationally.

Some clamps also feature:

Inserts allowing easy attachment of clamps along seams
Angled setscrews - for ease of installation when tool-to-seam clearance is tight.

Limited Lifetime Material & Workmanship Warranty

Read the fine print. Warranty language should back up sales claims in writing! At S-5!, we offer the most comprehensive warranties in the business.

Our free Limited Lifetime Workmanship and Material Warranty is offered on all S-5! products. It states that our clamps are true to our advertised claims and free from defects in material and workmanship on the date of the first sale and FOR THE LIFE OF THE ROOF.

Often a warranty of this type uses “escapes”, like “...IF in the sole discretion of the manufacturer…” and “...claimant must pay all shipping and handling charges…”

There are no “ifs”, “ands” or “buts” in our warranty language. If we screw up, we fix it!

Rigorous & Accredited Laboratory Testing

Tensile load testing is vital to engineering any application and results vary widely with panel material, thickness, profile and even brand of manufacture. That’s why we have performed more than 3,000 load tests on 500+ different roof profiles, materials and gauges and two load directions:

Negative load normal-to-seam testing (pull-up) is performed on all Mini clamps
Parallel-to-seam testing (drag load) is performed on all standard (2-screw) clamps

No ASTM protocols for testing of metal roof seam clamps existed, so we created one back in 1992 before we offered any product for sale. All of our testing is performed in a third-party 17025 accredited laboratory. Test results and protocols are published on our website for anyone to see - simply log into our “load tables.” If you would like a copy of a specific, detailed lab test report, just request it online!

Ease of Installation

S-5! metal roof clamps were invented by a contractor and metal roof consultant, so they are designed with the installer in mind to reduce the amount of time spent on the roof and to increase field efficiency. All of our systems can be retrofitted to existing roofs or incorporated into new roof design with common tools. The instruction and process is easy enough for a DIY’er to follow.
