The deal with Solar Stack continues Unirac’s series of acquisitions, strategic partnerships, and new product and service introductions as part of its Better Solar Starts Here program to provide customers with the best installation experience for residential and commercial solar.

Non-penetrating innovators

Tim and Michelle Graboski, two of Florida’s most influential roofing veterans, founded Solar Stack with a singular vision: providing solar installers with a groundbreaking but simple mounting solution that does not penetrate the roof.

The founders applied knowledge gained from more than 30 years in the roofing industry and Tim’s service on the Florida Building Commission to develop a structural attachment of proven, code-approved commercial foam adhesive that bonds to the roof surface and anchors the patented Solar Stack pedestal. The product is equally well suited for fastened tile roofs, like those in Florida, and commercial flat roofs. It has had tremendous success in Florida, where it holds the most stringent certification for use in High-Velocity Hurricane Zones.

Tim Graboski, CEO of Solar Stack, commented: “A partnership with Unirac was the obvious choice, and we felt strongly that they were the ideal partner. We both share a passion and commitment for bringing innovation to the market and serving our customers, and we are very excited to see Solar Stack in the Unirac family of products.”
