Non-penetrating rooftop mounting refers to the ability to mechanically attach a clamp to a standing seam roof by gripping the seam in such a way that there is no penetration to the panel material. The best method for standing seam clamp attachment is via round-point setscrews.
Using cup-point setscrews is ill-advised as such a screw point cuts through the paint and protective coating of standing seam panels, causing corrosion and voiding warranties.
In the metal roofing construction industry, mounting ancillary items is often a convenient and necessary aspect of desired performance. Obviously, the best way to maintain the integrity of a metal roof is to allow it to function only as a roof. But various rooftop utilities such as, HVAC, piping, walkways, vents, satellite dishes, snow retention, solar arrays, signage, fall protection, lightning protection, etc. all serve critical purposes and must attach to the roof.

Word of the Week: Non-Penetrating Roof Top Mounting
PRONUNCIATION: /nän/ | \ ˈpe-nə-ˌtrāt
PART OF SPEECH: Prefix, Adjective
SENTENCE: // There are two basic methods available for mechanical attachment of things like snow retention systems to roofs: One uses the process of clamping to the seam (non-penetrating); the other screwing through the roof material (penetrating).
SYNONYMS AND RELATED WORDS: dimple, no rooftop damage, maintain roof warranty, mechanical compression
THE SCIENCE BEHIND NON-PENETRATING ROOFTOP MOUNTING SOLUTIONS: Mounting ancillary items to standing seam metal roofs requires secure and dependable attachment but need not cause puncturing. Metal’s malleability (ability to be drawn out or stretched) qualities make it a prime candidate for seam clamps. Using seam clamps eliminates unwanted holes in the roof and maintains the warranty.
The clamps themselves should be made of non-corrosive metals (e.g. aluminum with stainless-steel mounting hardware). Aluminum and stainless-steel offer the most compatibility with all metals except copper. If copper roofing is involved, use brass clamps and stainless-steel to help alleviate metallurgy issues.
