The visionaries behind the product

Fred Harkness

  • President

Fred has been a builder for over 35 years as owner and operator of Harkness Built construction and design firm. Through many years of residential innovation, design, and construction, it became apparent to Fred that there was a definite need to improve and integrate roofing and energy technology. This became his ambition, and after several designs, prototypes, and tests, Fred installed the pilot system on a residential garage. With a year of initial testing in hand and positive efficiency results from preliminary tests from the Florida Solar Energy Center, Fred went on to develop INroof into the business it is today. With a patent pending and ICC-SRCC™ OG-100 certification in hand, Fred looks forward to bringing energy efficient and design-compatible roofing to consumers.
