Unhappy customer in Oakville in Oakville

In 2008 We hired Home Depot located at Winston Churchill and Dundas in Oakville to replace our roof. Home Depot sub-contracted the job to Cherry and Clark. The new BP shingles with a 40 year warranty were installed in August 2008. Ever since the new roof was installed we had nothing but problems, every time there is hi wind we worry sick about the shingles flying off the roof like tissue paper. Houses immediately located next to us were are all fine with no problem/damage but only our house. Our original roof installed by the builder was much more secured compared to the one done by Cherry and Clark. The workmanship is totally substandard. We had called Cherry & Clark and Home depot in the initial first, second and third year to come back to fix the problem and had to paid for the repair of their substandard work when the year warranty expired. We finally gave up and called other independent contractors to come do the job. However, the nightmare continues with no end in sight. With the high wind of this past Friday, three huge sections of the roof was gone. I will not recommend this company to anyone. We are not critical people, however, by sharing our bad experience hopefully will spare someone else of the same grieves that we went through. It is typical of this company to deny their responsibility based on our past dealing with this unethical company. We have all the paper work to show who did the work even though Home depot was the one we placed our order with. It is common knowledge that all Home depot and Rona type of stores contract out their work to local contractor and do not have their own crew to send to the job site. Please do not try to fool anyone.
