The roof leaked less than a year after installation.
At first, they said it was an ice bridge, that there's nothing they could do about it.
Then when it continued to leak and the temperature could not justify the ice bridge explanation, they finally came to patch it with a type of glue.
But the real cause of the leak was not addressed: when remaking the roof, they reused the valley flashing that was there, saying it was good at least another 50 years. It obviously was not.
When they came to patch the leak, they said the glue was good at least 5 years, but that the valley flashing would continue to degrade because of its bad state, and that leaks would appear again soon. They pledge to come and redo the flashing valley in the season.
Now the season is ending, I did 3 follow ups by leaving phone messages to call me back in the last 3 weeks, and I still don't have a return call.
Apart from that, I would say that the staff is good to work with.
They were the lowest bidder, which in a sense is great, but only if you do end up with a roof that will last you as long as the ones from the competitors; by that I mean at least 20 years, not 5.
To sum up, if I had to choose again someone to do my roof, I'm not sure I would go with them, essentially because of the way they handle their customers in regards to warranty.
Note: a few hours after putting that post in, they called me back and said that they'll be there to repair the valley. I thus increased to 3 stars (initially 2). I do not know if it is related, but, as a company, I would make sure not to reach that point and promptly honor my warranty.

Winter arrived, and they never came as they said they would. I thus decreased to 2 stars again.
I write this so that if you think of investing so much money on a roof, I think this is a pertinent thing to consider: will they uphold their warranty and keep their word; in our case, they patched it with glue, and said it will leak again in the near future as the valley is in bad condition, but that they'd come back before the end of the season to change it, but never did come back. Now there's a feet of snow, and it's annoying to think that I'll have to run after them again if it leeks.
My advice for the owners: good word from your customers is a good publicity, and it's better to spend on honoring your warranty than in publicity, because an unhappy customer will, on average, talk 10 times more in bad of your company than an happy customer. In other words, instead of spending on ads on the streets, it might be better to be sure you honor your warranty and leave a good job; it costs less, both in terms of the job and in terms of reputation.
