Home Owner FAQs

What is Solar Stack?

Solar Stack is the only solar panel mounting system on the market that avoids roof penetrations. Our revolutionary pedestal is installed to the roof deck with a code approved foam adhesive. Solar Stack’s railless mounting system allows contractors to install solar panels directly to our pedestal.

How is Solar Stack secured to the roof?

The Solar Stack mounting system uses a highly innovative pedestal and code-approved foam adhesive to attach solar components to the roof.

Does Solar Stack have a warranty?

Yes! Solar Stack has a 20 year limited warranty. For more information please visit our technical page.

Does the foam adhesive work and does it last?

Yes! Foam adhesives have been used in Florida’s HVHZ (High Velocity Hurricane Zone) to adhere tile roofs since Hurricane Andrew hit in 1992. Our parent company Tim Graboski Roofing has been in business for 32 years in South Florida and has installed over 40,000 tile roofs with foam adhesives.

What roof systems does Solar Stack NOT work with?

Do I need rails?

Solar Stack eliminates the need for rails and racks. Instead, your additional mounting hardware can be installed directly to Solar Stack. This allows you to install solar panels directly to our pedestal. We have two quarter-inch channels and a half-inch channel allowing you to use any mid-clamps and end-clamps on the market with our system.

What about wire management?

Contractors can either run their wire management from pedestal to pedestal with cable ties or they can use solar panel clips.

Where can I find engineering reports?

Please visit our Technical Page for official certifications and engineering reports. 

Is a primer required for adhesion to the foam adhesive?

A primer is not required but is recommended for most roof systems. Please email info@solarstack.com for more information.
