I've had the privilege of calling Mr. Demos for an issue on my roof. He showed up on time, and went to inspect the roof. He told me that I needed to patch up a small issue in order to fix the condensation. He ended up taking care of it, and didn't charge me for it, since it wasn't a major job. Before contacting this company, I went with another one to get an estimate, and they came back to me with a 3000$ bill for the work they'll do. Simply put, Demos roofing won't charge me unecessarily, and are honest with the clients at all times, only proposing services when it is actually needed. This transparency and trustworthiness is hard to come by these days, but it was never an issue with Demos Roofing. I recommend them to all for their honesty, transparency, and work ethic. You can't have a better combination.

Billy and his crew are amazing! Had leak on my garage roof and gave Billy a call. I'm on the road as a trucker and Billy set my mind at ease by telling "don't worry I will take care of it". Even though i was out of town for another 2 weeks! Happy wife happy life! The leaky garage was no longer a burden for my wife. 2 days later Billy, true to his word, took care of it,no leaks since. I was so impressed with his customer service and work that I asked Billy and his team to return for an asphalt roof that was in high need of redoing ...he looked after everything, guided me through dealing with hydro (due to a close power wire to roof line) was thorough and cleaned up the job afterwards. I couldn't be happier...if you need a roofer Billy and his crew are who you want to work with, hands down!!

The first time I met the owner of Demos Roofing was in the year 2006. Since then they did some small work on the roof of my commercial building because of leaks. I was Impressed with the owners attitude, kindness, honesty and the quality of his work. "Honesty is the first chapter in the book of wisdom." Thomas Jefferson.The month of May 2018 they did the roof of 3.500 s.f on the same building. I must say that they did an Excellent job and used first quality material!! The owner and his staff are Amazing! I highly recommend this roofing company to everyone. Thanks to all of you!

Couvreurs Demos "Demos Roofing" have done a great job. Billy is extremely honest, responsive and professional. Since the start Billy provided his opinion about my roof and how to proceed. he explained in details my options and was extremely honest. Billy and his team provided a great job and were extremely professional and cleaned up everything very well after the roof installations. I highly recommend Demos Roofing for any roof related job you have.

I am an engineer and use DEMOS ROOFING for all my expertises and contracts. They have always served me well and the owner is as honest and straight up as can be. I won't use anyone else and I am very happy when the customer says that the DEMOS ROOFERS were professional and left the place looking much better than when they arrived. Billy Demos (the owner) has all my support and I will continue working ONLY with them.

After a few estimations, I stuck with Demos Roofing simply because of their honesty and price for my recent purchase. They we're very competitive in pricing and I felt a sincerity during the estimation. The job was done very clean and their staff was surprisingly friendly. I recommend them to anyone, and that's why I rated it 5 Stars. Thank you very much once again!

Unfortunately my property is located in an area that does not have enough space for the truck to access the roof. Billy was very professional and being super honest about it. He gave me good advice that helped me to decide what to do next. Very much appreciate you taking the time to check my roof and gave me advice, Billy. You are the best!

I called Billy Demos for an emergency repair, we had a major leak. I was extremely satisfied by the reliable and professional service Billy provided, he came quickly, identified the source and fixed the problem. I'm confident he is one of the most trustworthy roofers in Montreal. Would highly recommend!

Billy was recommended by my neighbor. He went to redo her roof he was honest and only did a repair that was needed not the complete roof. Summer 2020 he did my roof. Was an excellent job. I highly recommend him.
