TRT01 Rail-Less Solar Mounting is built specifically for asphalt composition shingle roofs. It integrates the base and mini-rail into a single unit, attaches with double butyl adhesive, and requires no traditional flashing. The result is a faster installation with fewer components, a cleaner roof finish, and a fully waterproofed penetration that meets UL 2703 listing requirements.
The system is PE certified, Class A/B fire rated, and tested to ASTM D7147 and TAS 100(A) for uplift, shear load, and water penetration. For base spacing and layout requirements, use TRT’s PE-certified span tables.
For installers who need a repeatable, code-compliant workflow on composition shingle roofs, the TRT01 Rail-Less Solar Mounting system removes the alignment challenges that come with traditional rail-based systems. Fewer parts, simpler crew training, and the same consistent process across every attachment point on the roof.
