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. What should you do if this is happened to your roof?? Thanks for reply.
