What we do and why it matters


A racking partner you can trust.

Sunstack was founded with integrity in mind. Integrity Solar Mounts, or ISM, is comprised of the team members you might already know. 

Taka, Mike and Joe are leading experts in top-down butyl-based roof attachments and have been change makers in solar racking for over a decade.

Through ISM, the team partnered with solar contractors across the country to develop bespoke racking solutions to suit their changing needs. And just like that, Sunstack was born. 

"Our expertise in the industry and our commitment to integrity is what makes us different. Our reputation keeps our value proposition simple:

We don’t just build products to sell, we build partnerships to last."

-Taka Chiyoda

"Right now, Sunstack is an unknown brand, but knowing the guys behind it, I'm sure it won't be for long.

For years, I have relied on them for their expertise and knowledge in materials, applications and pretty much anything related to rooftop solar.

This team has always been available when I call, and their support is always straightforward and reliable.

The Sunstack team keeps their standards high and that's why I trust them."                                            

           -Brian "Buz" Buzbee
