RoofClamp RC: The Universal Non-Penetrating Standing Seam Attachment
The RoofClamp RC is an innovative, high-strength attachment solution designed to secure satellite dishes, conduits, HVAC lines, signs, and solar arrays without piercing your metal roof. Crafted from lightweight, structural-grade aluminum, this patented one-piece clamp provides a secure mounting point while preserving the roof manufacturer's warranty.

Universal Fit, Professional Holding Power.
Watch this technical overview to see how the patented RC and RCT series clamps accommodate over 90% of standing seam profiles.
Why Professionals Choose RoofClamp RC
- Non-Penetrating Technology: Uses stainless-steel cupped-tip screws to create a "button lock" attachment. This ensures a secure grip without piercing the metal skin or causing leaks.
- Universal Fit Profile: Engineered to fit approximately 90% of today's standing seam profiles. The 1"W x 1"H interior dimension provides a stable mounting platform for a variety of rooftop accessories.
- Patented One-Piece Body: Features a robust, single-piece aluminum body (US Patent Number D658,977) for superior structural integrity compared to multi-piece alternatives.
- Reusable Hardware: Unlike single-use clamps, the RC utilizes anti-seizing, coarse-thread set screws. This allows for easy re-attachment, re-positioning, and re-torqueing without damage.
Important Safety Note: The RoofClamp RC is designed for equipment mounting only and must not be used for fall prevention. For certified standing seam fall protection, please see the SSRA1 Standing Seam Roof Anchor.

RoofClamp RC Frequently Asked Questions
1. Will the RoofClamp RC fit my specific metal roof?
The RC model is designed to fit most seams up to 1 inch wide. This covers roughly 90% of the standing seam profiles currently in use. For larger bulb seams or T-style profiles, please refer to our Compatibility Chart.
2. Does this clamp void my roof's warranty?
No. Because the RC is a non-penetrating system, it does not pierce the metal panels. This preserves the roof's watertight integrity and is generally accepted by panel manufacturers as a warranty-safe attachment method.
3. Can I reuse these clamps if I move my equipment?
Yes. Unlike many competing products that use fine threaded set screws, our anti-seizing coarse threads allow you to unscrew, move, and re-torque the clamps multiple times.
4. What is the difference between the RC and RCT models?
The RC is our most popular "universal" model. The RoofClamp RCT is often used for specific taller or wider bulb-style seams. Both are featured in the technical video above to help you identify the best fit for your project.
5. Is a torque wrench required for installation?
We highly recommend using a torque wrench (set to 90-110 in-lbs) for professional installations to ensure uniform holding power across all seams.
6. Can I use this for a Starlink dish or solar panels?
Absolutely. The RC is an ideal base for J-mounts, satellite masts, and L-feet for solar rails. The 3/8" top threaded hole makes it easy to bolt on standard mounting hardware.
7. How do I avoid common problems during installation?
- 1. Don't Over-Torque: While strong, overtightening past 90 in-lbs can potentially damage the clamp or the seams.
- 2. Clear the Debris: Ensure the seam is free of dust or construction debris before sliding the clamp onto it to ensure a flush fit.
- 3. Low Seam Install Tip: For seams 1" or shorter, it might be helpful to use a flex bit in your screwgun to help line up the allen bit with the set screws.
