What Our Customers Say
Rated 5 stars across Google and HomeStars by homeowners throughout Central Ontario.
Amazing work from start to finish. The quoting process was detailed and accurate. The installers showed up exactly as scheduled and took time to protect the house and surrounding area with tarps. The existing shingles were stripped and the new roof was on, all inside of one day. Aside from a great-looking roof, there was no sign of the crew ever being here. Fantastic work! I couldn’t be happier.

I have no words to describe how truly and greatly appreciative we are for JN Roofing. From the first meeting with Mike to execution day. This company is beyond pristine in their workmanship. They were beyond helpful, honest, and kind and they had their routine and jobs down and it shows. From start to finish it was flawless. They were here before start time, kept everything tidy, and cleaned everything up perfectly. JN Roofing we truly cannot thank you enough from the bottom of our hearts for fixing our disastrous roof. We will definitely be recommending you to everyone we know. You truly are an amazing team.

JN Roofing is amazing. We had our whole roof/shingles done this week and they were on time, efficient and professional, and super nice. Being first-time homebuyers we were a little nervous with it being our first big home project. But we absolutely would recommend them to everyone. From our first quote, meeting and even helping with shingle samples they were wonderful to deal with. 100% happy with the job they did. 10/10. Great job guys and thank you.
HomeStars Customer Review (5 stars)
The team just got finished doing my roof. Really very professional service. All the property was tarped and protected during the service, the team was fast. The quality of the materials was exactly what I was expecting. I couldn’t ask for anything more. Thanks very much!

Choose JN Roofing – you will not regret it! They came on time to quote it out and to complete the service. They send a crew large enough to finish in one day. They take time to remove things around the yard and protect from damage. Their prices are competitive and they have their own insurance. They do not contract out and do the work themselves. A big selling point for me is that they have a brick and mortar location locally. You hear a lot of scams with the various trades but having a place to go if there are issues or concerns is an added layer of confidence. They showed up around 7am, the date of service and were gone by noon. I can certainly see how they have been successful in business for many years.

I came into contact with JN Roofing and Contracting through a family friend who suggested (them) to me, and wow, what a great suggestion. They were in and out in less than a day and left my yard absolutely spotless. Extremely professional and respectful to me and my family. Extremely satisfied with the quality of work as well as the way the employees conducted themselves on the job site. Thank you for a job well done.
