Racking That Survives the Roof
The racking system is 10% of project cost and 90% of leak risk — choose flashed L-feet or standoffs matched to your roofing material, and rails rated for your local wind and snow loads. IronRidge XR rails cover most residential spans; Unirac and K2 handle ground mounts and commercial ballasted systems. Always order mid and end clamps sized to your exact module frame height — a 30mm clamp will not seat on a 40mm frame.
Pro Tips
- Match clamps to module frame height — 30, 32, 35, or 40mm
- Check ASCE 7 wind and snow load certification for your county
- Flashing plus L-foot on comp shingle; standoff on tile
Racking & Mounting — Frequently Asked Questions
How do I size mid and end clamps?
Clamps are sized to your module frame height — typically 30, 32, 35, or 40mm. Check the panel datasheet; a 30mm clamp will not seat on a 40mm frame.
What attachment is right for my roof?
Comp shingle gets a flashed L-foot or standoff; standing-seam metal gets non-penetrating S-5! clamps; tile needs a tile hook or replacement-flashing mount. Never lag straight through shingles without flashing.
Is the racking rated for my wind and snow loads?
IronRidge, Unirac, and K2 all publish ASCE 7 span tables and certification letters for permitting. Tell us your county design loads and we will spec the rail and attachment spacing.
Do you sell complete racking BOMs?
Yes — send a panel layout and we return a full bill of materials: rails, splices, clamps, attachments, flashing, and grounding hardware, kitted per array.
