Do we recommend Southern Illinois Solar?
Southern Illinois Solar fills a gap that most solar companies don’t even think about. As the solar arm of Joiner Sheet Metal & Roofing, they bring something genuinely rare to the table — deep roofing knowledge combined with Illinois DG Certified solar expertise. That combination matters more than people realize, especially when it’s time to replace a roof that already has solar panels on it.
Their detach-and-reset service has grown into one of their biggest lines of business, and it’s easy to see why. Most roofers aren’t licensed to properly handle solar panels, and most solar companies don’t understand roofing well enough to coordinate the two. Southern Illinois Solar sits right in the middle — and they do it better than anyone else in the region.
Beyond re-installation, they’re registered with Illinois Shines to support stranded customers whose original installer has gone out of business, handle SREC application filing, and offer commercial solar assessments focused on real return on investment. For agricultural customers, they also provide practical solar solutions for grain drying and rural electrification.
If you already have solar and need help, or you’re starting fresh and want a team that understands both your roof and your panels, Southern Illinois Solar is a dependable, no-nonsense choice.
