Looking for Roofer/Contractor recommendations to prepare for solar

Howdy Neighbors, I'm looking for any contractors or companies to call (or avoid) to help restructure the roof of our garage this summer. We're looking to install solar panels on our garage roof and this restructuring would maximize the amount of panels we can install and the amount of energy those panels can generate. The roof is old and requires a replacement, and we also want to convert it from a four-sided hipped roof to a single plane roof (the new angle would also require adding some siding). As always, any help is greatly appreciated. Thank you, Scott Meldrum
