I had the same problem with the roofer,only mine was more disastrous and dramatic. I hire a roofer to do my entire roof and new fence for 17,000. They promise me the job will be complete in 4 days. Now it was on the 10 days now my roof still not complete, and they tore my fence down 5 days ago and the fence still not up yet. I had 3 different types of felts on my roof,multicolor shingles, and the ridges on the edge look like a snake climbing on the roof. And they use nails for shingles to nailed my felt with the nail gun ( I am sure my roof deck is damage cause of all the nails they shot on my felt and shingles). They also damage my gutters in the process installing my roof. I gave the roofer numbers of chances to fix it right, but he never gave me a direct respond to how he is going to fix what they had already messed up. And his promises on the job completion date were excuses. If I fire him now, is that breach of contract?? What should you do if this is happened to your roof?? Thanks for reply.
