I hired A One Roofing to fix a water leak in my laundry room. They sent someone to assess the leak, which I showed them personally and made a plan for addressing it which included flashing and cocking on the roof above. Unfortunately, the leak persisted after the work was done. I called back and another roofer came and applied a bit more cocking to other places but again no improvement on the leak. I called a third time and another roofer came, who said he had now found the real source of the leak this time but it will cost an additional $800 to fix. They didn't budge on this price and I did not agree to it so no further work has been done and the leak persists, so I will need to find another company to do the job properly.
In summary, this company charged me $400 to place flashing and cocking that did nothing to improve the leak I had hired them for. They then tried to charge me triple the original price agreed on when it was clear their work was not effective.
