S-5! Offers Both Top-Fix and Bottom-Fix Brackets to Support Multiple Water-Tight Roof Mounting Applications

Roof cultures vary worldwide. In some cases “bottom-fixing” is the common culture. In others “top-fixing” is the only acceptable practice. S-5! manufactures various metal roof brackets to ensure the best attachment solution for your application. Choosing the correct load-tested bracket for your specific roof type, gauge, material and roof culture is made easy on these pages.

You can have peace of mind knowing S-5! product designs will outlive the life of your roof. All seals, gasketing and part designs are industry standard and state-of-the-art. These are the same sealant/gasket chemistries used within the metal roofing industry for weather integrity of the roof itself and proven over the past 50 years.

Metallurgical compatibility to the roof is assured. Our goal is for you to have the best solution at the lowest possible cost for your specific application without compromising roof integrity.

Find the Metal Roof Bracket that Best Suits Your Application.

Our metal roof brackets are specifically designed for exposed-fastened, trapezoidal-rib and corrugated roofing profiles. They use two to four fasteners for attachment and some are mounted in the high (above the water plane); others in the low. Use S-5! Exposed-fastened metal roof brackets to mount solar modules, snow guards, HVAC, satellite dishes, roof walkways, wind uplift enhancements, lightning protection, signage, pipes, conduit, fall protection, module-level power electronics and more.

Brackets that attach to “sheet-only” include attachment screws.

For brackets that attach to the structure, we offer metal-to-metal and metal-to-wood screws (sold separately).

Expertly Designed & Engineered; No Time-Consuming & Risky, Field-Applied Sealants!

When attaching above the water plane we use EPDM (ethylene-propylene-diene monomer). Many of these attachments are “sheet-only” enabling more versatile placement on the roof.

When attaching at the water plane, we use butyl crosslinked (poly-isobutylene-isoprene) polymer and always through to the structure. All part designs incorporate features that protect the seals from U.V. degradation and over-compression from installation and service loads.

S-5! part designs above the water plane avoid attachment to the flat top of the rib, and instead attach at its side.

This eliminates capillary entrapment of moisture at the bracket-rib interface, which can lead to early corrosion of most roof materials. It also places the fastening in-shear rather than direct-withdrawal, exponentially increasing the holding strength.

All S-5! sealants are factory-applied, reducing installation costs and eliminating the chance of inferior sealant choices offered by a common building material center. Our bracket seals are leak-tested to the most demanding ASTM E 2140 (5”; 127 mm) static water (flood) tests. All exposed metals are long-life and non-corrosive.

Verifiable Quality Assurance

To ensure the products tested are truly the products sold and shipped, traceability, transparency and certified manufacturing are essential. We only use certified material, certified testing and certified production in our own ISO 9001:15 manufacturing facility. Regular ISO inspection/auditing ensures the quality control system performs as advertised.

We stand behind our industry-leading warranties, endorsements, track record and customer service satisfaction - giving you the confidence that we offer “the right way!” to mount to your metal roof.

What is the S-5! Difference?

S-5! ColorGard VersaBracket Work Monster Sky Products

Innovative Fastening Technology

S-5! Exposed-Fastened metal roof brackets feature two or four fasteners for attachment, depending on project load requirements.

S-5! screws are specifically designed for our parts and applications. They are different from any “off-the-shelf” fastener and our load testing is contingent on their specific use. Only use genuine S-5! screws to preserve warranty and ensure the best quality. Purchase screws from your authorized S-5! Distributor or directly from S-5!

S-5! self-piercing screws:

Maximize thread engagement
Avoid creating swarf which can rust and stain the roof as normal drill-screws do
Maximize stripping torque, shear, and withdrawal strength – providing up to 10 times greater tested holding capacity than top-down attachments from other sources
Utilize state-of-the-art sealing washers
Utilize stainless steel on all exposed surfaces

We Only Use Chemically and Mechanically-Certified Raw Material

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

S-5! Metal roof brackets use non-corrosive materials and are metallurgically-compatible with common roof materials - titanium-zinc, stainless steel, aluminum, zinc, galvanized steel, Bonderized™ steel, CorTen steel, and 55% AlZn coated steel (Galvalume®, Zincalume®, ZintroAlum®, Zink-Al™).

Made from 6000 Series AL with 300 Series SS Hardware
All fasteners feature either a stainless steel or zinc-aluminum cap with EPDM washer

Different specific alloys of these materials have varying characteristics that affect tested holding strength and corrosion resistance. Unless the raw material is certified, it is not possible to ensure the consistency of the strength and corrosion-resistive characteristics of the finished product.

Lifetime Material & Workmanship Warranty

Because we utilize all certified procedures in raw material, testing and manufacturing, we are able to offer a Limited LIFETIME Materials and Workmanship warranty on all S-5! components.

Warranty language should back up sales claims in writing! At S-5!, we offer the most comprehensive product warranty in the business.

Our LIFETIME Warranty is offered on all S-5! products, and is cost-free. It says that our clamps are true to our advertised claims and free of any defect in material or manufacture 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 it up, we replace it - period!

Rigorous & Accredited Laboratory Testing

It is impossible to properly engineer exposed-fastened metal roof brackets without knowing its holding strength capacity. To be of any real value, load testing of a bracket has to be specific to the material to which the bracket is attached and to the bracket design itself. Different dimensions and gauge thicknesses of roof materials are available in the marketplace. Due to these variables, they can have different holding capacities.

We have performed a plethora of load tests on different roof profiles, materials, gauges, and substrates.

We perform negative load normal-to-seam testing (pull-up) and parallel-to-seam testing (drag load). Results are published on our website.

2,000 hours of salt-fog testing is conducted on S-5! components according to ASTM B117-19.
All exposed-fastener brackets and screws are tested for waterproofing via ASTM E2140.

RibBracket Sealant Exposed Fastened Metal Roof

S-5! Bracket Sealant Technology

S-5! metal roof brackets feature integrated sealant reservoirs to prevent over-compression of the seal and to protect the sealant from U.V. degradation.

A watertight, factory-applied, 60-year butyl polymer seal is used on S-5! brackets that attach to the decking or structure in the drainage plane of the roof. This butyl polymer along with the EPDM seal on the fasteners forms what we call a “triple seal”.

The EPDM factory-seal is used on sheeting-only attached brackets that mount on roof ribs or corrugations out of the drainage plane. This creates a “double-seal”.

No risky, field-applied sealants are ever used. Instead, you get permanence, maintenance freedom, and peace of mind.

Ease of Installation

S-5! exposed-fastened metal roof brackets 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 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.

Quick and easy installation
Installation utilizes common tools of the roofing and construction trades
