HOME DEPOT INC

I went with Home Depot Roofing Installation services thinking they were a major company and could be trusted and correct any issues that would come up. I agreed to have them do the work and told him I didn't want the job done until end of October.  I received a call scheduling for the next week.  I explained I didn't want it done until end of October.   In October they called and scheduled.  
The shingles were delivered the day before they were to do the job.  The morning of the roofers arrived early looking like they slept in their clothes and just rolled out of bed and first thing wanted to use my bathroom.  They were contractors from northern IN.  There were 3 of them, the 2 on roof and foreman on ground .  They started right away and foreman told me the planking was all good.  I noticed they didn't have any vents.  He said he didn't know anything about them.  
I called the sales guy and he did drop 4 off at house so the roofers could install.    They didn't finish that day and came back the next morning and worked until early afternoon.  When finished I asked about the flashing around the chimney's   He said he didn't know about it and that you couldn't put flashing around them.  He called the salesperson and told him he couldn't do it.  (and no flashing was delivered anyway)
So I now had a nice black roof with ugly things stick up from it, peeling paint, etc.  I called the salesmen and Project Manager for the job.   It took I think over a month to hear back from him.  I left many messages to contact me.  Finally the PM came to the house and said he would send someone to clean them up and paint the chimneys.   Someone did come to the house while I was at work and used a wire brush (I assume) and brushed off some of the paint and then painted them black.  It looked better (not as noticeable) but you can see the paint ridges from the old paint and it really doesn't look all that great.  
In my limited knowledge the actual shingle part of the roof job was done well and I have had no problems.
With the price and issues I had I will never use home depot installation services again unless the installation is being done by a local reputable company and they provide the Home Improvement bid
The roofing experience left a bad impression. The salesperson is a Home Depot employee and is my opinion not knowledgeable about roofing and should have know what they could and could not do.  Putting new pipe boots was never mentioned and I wish that had been done too as they leak when we have hard rain. 

We expected a higher level of communication, customer service, and follow-through in dealing with Home Depot.
