Flat Roof Attachment

Engineering Down to the Deck

Low-slope roofs (0-6°) are extremely common in residential and commercial buildings, but the roof construction and the structural system below vary significantly, creating a challenge for designing solar arrays.

The IronRidge® Flat Roof Attachment combines a high-strength cast aluminum base with a 16-point fastening pattern to enable the widest range of design options on low-sloped roofs. Compatible with most common roofing materials to ensure a system that is easy to integrate down to the deck.


Sealed from above with a “blind hole” and pre-installed sealing washer, the Flat Roof Attachment delivers integrated waterproofing with popular roofing systems.


Made from high-strength cast aluminum, the 7″ wide, heavy-duty base delivers superior uplift and lateral capacity compared to any other product on the market.


12-straight and 4-angled fastening options provide maximum capacity and versatility with wood, steel, decks, beams, and even concrete slabs.


Formed membrane covers are matched to major roofing brands to ensure a tested, engineered system for TPO, PVC, and KEE roofs. No additional sealant necessary.
