Unirac, a North American solar PV mounting manufacturer, and Solar Stack, a Florida-based manufacturer of the non-ballast, non-penetrating solar mounting solution, have announced an exclusive global license deal for the Solar Stack product.
With the signing of this technology deal, the two companies are poised to expand on the momentum set by the founders of Solar Stack. The deal with Solar Stack continues Unirac’s series of acquisitions, strategic partnerships and new product and service introductions, part of Unirac’s Better Solar Starts Here program to provide customers with the best installation experience for residential
and commercial solar.
“We are very excited to announce the partnership with Solar Stack as our quest continues to demonstrate our market leadership,” said Peter Lorenz, CEO, Unirac. “Continuous improvement and innovation are the keys to pushing the market forward, and this partnership is yet another example of that.”
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, the company said in a press release.
“A partnership with Unirac was the obvious choice, and we felt strongly that they were the ideal partner,” said Tim Graboski, CEO of Solar Stack. “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.”

Hi! This sounds interesting and promising. Can you guys also talk about warranties and what happens when after installation, some years later, house needs re roof (asphalt shingles)??? Thanks, Edwin Guerra
PS: can Mr Holt elaborate about his comment? Is he part of solar stack or is he disputing with them this patented technology

It looks like you cut through the single and underlayment to reach the wooden deck on a comp shingle. I will be looking into this. Calling it non-penetrating is probably not totally accurate for tile or comp. For those two, I would call it less-penetrating or soft-penetrating or deck-fastening. The seal in and around the comp or tile wold be of concern to me. We need to test in-house under stress to see if that seal holds over time. I am excited about this though…
JOHN HOLT says
Dear Mr. Ludt,
This purported new Non-Penetrating attachment system is infringing on my Patent No: US 10,145,116 B2 with final issue 12/04 2018. filed under Holt et al. Titled APPARATUS AND METHODS FOR SECURE, NON-INVASIVE AND NON-PERMANENT SURFACE ATTACHMENT SYSTEMS. Thank you for bringing this to my attention; and could you please direct me to the source within UNI-RAC before they make a very expensive mistake of licensing intellectual property belonging to someone other than who they should be licensing from.

For shingle and tile it is not non-penetrating. You have to cut out the shingle and tile and adhere to the underlayment underneath:

No holes in the roof = non penetrating

When installed on a pitched roof on comp shingles, aren’t we now relying on the connection of the shingles to the roof sheathing for strength of attachment? I can see this product working well on roll comp, tile (per recommended installation) and especially on flat roof. I question comp shingles on a pitched roof. What does the testing tell us?
