Roofers came to re-shingles the house and there are some issues. Mess in yard from discarded old shingles, nails laying about and plywood exposed on one side of house. Shingles are to protect the plywood but exposed wood will rot and a problem can/will occur. Called and e-mailed rep and the Rep has yet to return messages and come inspect the work. been ongoing since November 9. Getting more annoyed every day. A response would be appreciated.
