"We could not have been happier with our experience with Shanco. Steve H***** was our project manager. The entire process went smoothly and they ambeat their delivery date. The installation crew was on time and worked efficiently and the roof looked great. We couldn’t even tell they had been there after they left. I saved this for last. Shanco was also the best price we received."
