Peter in St. Louis 5 reviews Ballwin, MO Joined 2008/05/21 First Review 10/10 Fixed a hole in my roof. Roofing review in Ballwin Over 10 years ago Frederic Roofing fixed a hole in my roof, not a whole new roof. They simply did an amazing job. The workers were happy the whole time, and now you can't even tell where the hole was. I highly recommend. Job Price Was this review helpful?
