- Work was done incorrectly as confirmed by IKO (shingle manufacturer we used), city inspectors, 3 fellow journeyman carpenters, multiple shingle suppliers, and the Alberta Roofing Contractor Association. Two of his workers were also overheard saying “This is the wrong way to do this.” - Towards the end of the job, a worker said, “We might be short on shingles.” Another worker’s response was "I have lots of pieces here we can use". (Pieces aren’t meant to be used). - Drip edge installed too short exposing house to rain and places where no drip edge was installed at all. - Joints of shingle overlap 2 1/2 inches apart, many other joints at 4 inches. (Minimum 6 inch overlap per IKO specs and they actually recommended 10 inch for our style of shingle). - Some shingles were reused after being torn up and now have nail holes that aren't filled. - There are nails not sunk properly to the point they are already starting to push shingles up as shingles settle down flat. There are places where there is 2 nails/shingle and IKO specs require at least 4 (6 depending on where the shingle is located). - They didn't clean my property and left a mess on neighbors property, which we cleaned up. - They damaged 2 week old siding, eavestroughs and a deck that is 1 week old. - When asked mulitple times if they were going to fix the issues, the owner walked away while saying we didn't know anything. - Workers were caught multiple times not wearing harnesses and they smoked pot at lunch on our property.
