We've used these guys a few times over last couple years. They've been consistent in terms of price and professional service. And they're always very prompt with response and getting to the problem. I've been very happy with the results each time. Highly recommend.

Customer service and quality of work could not be better. A great experience from start to finish. You will not be disappointed. Give Sam a quick call and you will know what I’m talking. Thanks Sam.

We hired Roofing Pros of Ontario to replace the main roof and the flat roof of the garage. They did a fantastic job! specially on the flat roof that was a bit tricky and needed some repair. The original estimate was to finish both roofs in a day and a half. Both were finished in one day! thanks to the hardworking crew that started at 7am and worded 12 hours nonstop!
They were particularly careful not to cause any damage to other parts of the house and they cleaned all four sides of the house at the end (much cleaner than before!).

Roofing Pros of Ontario provides superior service to their customers. Sam and his crew are very professional and make roof replacement relatively painless. My roof looks great and I do not hesitate to refer and recommend this company.

Had Sam and his capable and hard working crew refinish my roof with GAF products a week ago. Everything went as planned and am very pleased with finished job and GAF warranty. I highly recommend this company.

Sam replied to our service request quickly and in a professional way. He went out of his way to explain our options, replying to texts and calls well after normal business hours. Definitely recommended!

I'm the homeowner for over 20 years and Sam was the best contractor I have ever met. He responded within a few minutes after I requested to HomeStars. He offered the best deal in terms of quality of supplies, time and money. And after his crew completed the job I was amazed with what has been done. Sam not only highly recommended, he must be chosen if you are looking for the best quality.

Sam was working on my neighbors house and I had the same problem. I spoke to him that day and booked in the work to fix the area over the entry way (flat roof) and a dormer that leaked. He went up to check it out and told me exactly what needed to be fixed. We signed the agreement and he just finished the work today. He is great at what he does and was clean, efficient and added the roofing protection that should have been there from the start. He also informed me that the heating coils we have were not installed correctly and gave me details on how to fix them. I would never have known. I would definitely recommend Sam and his team for roofing work (repairs or installations).

Shingles felt off after a windy day. They answered my call within 24hrs. They thoroughly checked the roof and suggested solutions. The estimate is reasonable and apply fixes with great craftsmanship.

one of the downspout was fallen down because of ice and Sam was very responsive and fixed it quickly despite the bad weather and his rate was really reasonable. I fully recommend him
