Roof Tech

Roof Tech, Inc. designs and manufactures waterproof mounting systems for solar photovoltaic installations. Headquartered in San Diego, California, the company is the first U.S. subsidiary of Yanegiken, a Japanese roofing technology firm with more than four decades of experience in the field. Its teams are spread throughout North America to serve distributor partnerships regionally.

The company's engineering work centres on self-flashing roof penetration technology, waterproofing and sealing, and both rail-less and rail-based mounting design. Its product lineup includes AlphaSeal™, a self-flashing technology intended to provide 100% waterproofing; the RT-MINI and RT-MINI II rail-less PV mounting solutions; RT-APEX; and RT-RAIL, a rail-based mounting system. The products are designed to preserve roof integrity over decades of service.

Roof Tech reports more than 1 million rooftop installations across Japan and North America, with zero leaks recorded across all installations. Its systems are used in residential and commercial solar photovoltaic installations, addressing the leak-free performance and roof-integrity requirements demanded by installers in the roofing and renewable-energy sectors.
