The crew arrived on time and worked quickly. However, they only do bare minimum as far as application goes so be sure to ask for extras such as Ice and water barrier as they only put three feet of felt paper. There was a gap between my sheathing and facia which was not pointed out to me and corrected. This later contributed to making a small leak worse. I wish they could have made some suggestions due to my low sloped roof to impove the protection of my roof. Lastly, A magnetic sweep wasn't done leaving nails around my property. I was told it was broken. Furthermore, when I had a leak it took them two weeks to show up and have a look which of course I had to call someone else to come and inspect it. I definitely do not recommed Ontario roofing.
