Business ProfileforGuns N' Hoses Roofing & Contracting

I hired ******* ****** (proprietor of Guns N Hoses) to replace my roof after her team did some temporary repairs following a windstorm in May/22. She provided me with tile colour options, but when I made my selection, she said that the colour I wanted was no longer available and had to be ordered from a different supplier at an increased cost. I agreed to the extra cost, and she sent a new invoice to me on July 14/22. On July 18, we both signed a very detailed contract. I made the down payment requested, and the work commenced in mid-August. NOTE: The contract had been revised several times before I agreed to sign it, and I noticed that each time a revision was made, there was no previous version available for comparison. So in order to determine if everything we discussed was accurately represented, I had to re-read the contract in its entirety each time she made corrections to it. I decided then to make pdf's of both the invoice and contract. The job was done with only minor details remaining to do, and ******* agreed to leave 3 full bundles of unopened tiles and an ice shield pack in my backyard. I submitted the final payment according to the invoice/contract we had signed. When I requested my receipt, ******* told me that she would be making some minor changes to the invoice. I asked her politely not to change it. She then informed me that I was responsible for the cost of all materials, delivery, disposal, labour, Contractor’s overhead and profit...to which I reminded her that our contract also included a Change Orders clause that specified that any changes in costs must be agreed to in writing...but that I was open to discussion. That's when she became nasty, She took back the extra tiles, did shabby work on my downspout, and informed me that if I didn't pay the remaining balance, there would be no receipt and that this invalidated my warranty.
