Interlock Metal Roofing installed a new roof on my cottage which is water access only

June 20, 2022

Interlock Metal Roofing installed a new roof on my cottage which is water access only. I've been in construction for over 45 years and the crew (Brian and Maurice) were two of the nicest, hardest working people I've ever met. They did a terrific job of installation, explained the unique benefits of the roofing system, worked long hard hours in the heat and never complained once. When my porch roof is ready for new shingles, I will request these two again and I will definitely use Interlock Metal Roofing again. Fantastic company.

Best money we ever spent

June 14, 2023

The Best money we ever spent was buying windproof Interlock Metal Roofing, especially after the devastating storm May 24, 2022. Our 4000ft Lake House and Boat House on Lake Scugog survived with no damage after that Storm and the one on Dec 24, 2022 winter Storm. We know Our Cottage is safe and protected when we are not their.

We had to replace our shingles after the 2022 hurricane

June 1, 2023

We had to replace our shingles after the 2022 hurricane in our area. We chose a metal roof (aluminum) because of its durability and wind damage guarantee. We have a large, steep roof with dormers. We got 4 estimates and Ontario Roofing was the most reasonable and professional to deal with at that stage. As we awaited installation, it was easy to get in touch with the company and the production manager for updates. We are very happy with the new roof and the quality of the installation. The 2-person crew worked steadily over 2 weeks. They were friendly, quiet, and hard-working. We would definitely recommend Ontario Roofing.

The future of roofing

June 1, 2023

Bruce was completely thorough in his presentation of why metal shingles were the future of roofing. Product selection was great, and Bruce was pleasant and friendly. The process was longer than expected, but the results were fantastic. Having the neighbours come by and ask questions definitely means we made the right choice. The compliments were many. Thank you to Interlock roofing and the team for their service and workmanship.

Treated our home with respect

June 1, 2023

Hi Peter, we wanted to convey to you how much we love our new Interlock roof! Several of our neighbors and friends have said they do, too! We love the look of it, and are so impressed with how beautifully finished it is integrated into the flashing materials. The Interlock scheduling staff was great to work with, and we are so happy with Jessie and his Interlock installation team. They are true craftsmen, and part artists! We loved how they treated our home with respect, and were always willing to address any questions we had. We watched as they worked on items until they had them just right; when we asked about some areas of concern multiple members of the installation team converged on the item and came down to explain and even illustrate with photographs how it was addressed. Again, we couldn't be happier and are enjoying our Interlock roof!

Great company to work with

May 25, 2023

We recently had our roof replaced. From the initial contact with Interlock/Maritime Permanent Roofing through sales representative John through to the roof replacement work with Brendan and the rest of the roofing team; everyone was professional, helpful and responded to us in a very timely manner. The finished product looks excellent and the work site was left clean and tidy. This is a great company to work with.

High winds at my lakefront site

March 31, 2023

Positive: Professionalism, Punctuality, Quality, Responsiveness, Value
I had an Interlock roof installed four years ago to replace an asphalt shingle roof that was continually being damaged by the high winds at my lakefront site. It still looks as good today as when it was installed. Bruce and the Interlock team dealt professionally with the inevitable surprises that arise during any construction project, and ensured the job was completed on time and on budget. I have received many compliments from neighbours and friends, and have no hesitation in recommending Interlock to anyone contemplating a new roof.

Withstanding all the windstorms / snowstorms / heavy rainfalls

March 21, 2023

Hi Mike/Scott and Interlock Roofing!!! We hope you are all well and doing great! We just wanted to get in touch to give you some feedback for the review. After 2 years we are very happy with our aluminum copper roof!! It is consistently withstanding all the windstorms/snowstorms/heavy rainfalls and tree branches falls in Belcarra which is the most important thing for us. Also everyone in the neighborhood had complemented on how great it looked. Again we would like to extend our thanks to your great crew that worked in pretty hot summer conditions and did a great job! And great thanks to Mike for being very professional and greatly flexible in accommodating our requests and needs. We had a very positive experience from the beginning all the way to the end. All the best to everyone!!!

Sincerely, Kara and Attila

Carter and his crew did an outstanding job from the moment Carter stepped in the house for the quote to the day his crew cleaned up and left. Very professional. I highly recommend Interlock.

We would recommend Interlock to anyone that is looking for a metal roof

January 15, 2023

We are very pleased with Nicholas and his crew. They showed up when they said they would and kept us informed as the project progressed. They were also very polite to talk to and cleaned up at the end of every day. Very professional.!! We would recommend Interlock to anyone that is looking for a metal roof. From the sales team through to the installation crew we felt that we were being looked after and everyone kept us informed through the whole process. Thank you to you all.

The snow simply slid off. It was incredible.

January 10, 2023

This is probably the most professional experience I have had in years. I was blown away. From the time I contacted them, they were on time and did exactly what they said they would do the whole way through. Someone is doing an excellent job of directing this company. I need to contact Paul or Ross because I have more roofs to put on. I would give them a rating of 475! My roof cost twice as much as any other bid, but I am ten times happier than I would have been with any other roof. People who see this roof compliment me on it. It will be spectacular once I finish the entire roof. The roof is stunning! There was no snow on the new roof when it stopped snowing last week; the snow simply slid off. It was incredible.

During hotdays the house seems cooler and the snow slide off during winter

December 30, 2022

We love the stylish new look our house got with the Metal Slate Roofing and the longevity Interlock Roof System offers. Although the roof is made of aluminum, the design makes the roof look as if it was traditional slated roof, hard to tell it is even metal. The crew professionally installed the new roof in no time. It has only been a few months since Installed but we have seen already some of the benefits. During hot days the house seems cooler and the snow slide off during winter. And the lifetime limited non-prorated roof warranty give us peace of mind.

It's a significant investment

December 27, 2022

We recently had a positive experience with our new roof install just before the awful weather hit - the hard working installation team finished the job in challenging conditions with diligence, good attention to detail, courtesy, and daily job site clean up. It's a significant investment and the company worked with us to resolve a couple of issues that did come up along the way, promptly and reasonably. Would recommend both the product and the team.

We wanted a good roof not a cheap roof

December 8, 2022

We ordered this roof because of the amount of debris that tends to collect on our formerly shake roof, and the difficulty of cleaning it, as needles accumulated in the space between the shakes and were difficult to dislodge. This new roof is relatively smooth and should be easier to keep clean (time will tell). Everything was as promised, appears to be good workmanship, was good communication and satisfactory in every way. Installers were friendly, cooperative and cleaned up thoroughly after each day's work. Took 2 1/2 weeks to complete but it is a big roof. Not cheap, though we wanted a good roof not a cheap roof.

The new roof is not only super functional for our New England location, but it also looks beautiful!

December 2, 2022

We had a new metal roof installed on our entire home, and we are very pleased with the quality of the product. Our installation had to be scheduled for after some other work being done on the house, and Interlock was very flexible with our ever-evolving timeline. As soon as we were ready, they had a crew at our house within a week and once started they were very quick to get the project done. The new roof is not only super functional for our New England location, but it also looks beautiful!

If the VP of a company gives you his personal cell phone number that speaks volumes to the confidence he has in his products

November 30, 2022

From our initial consultation at our home with Carter and Brian (VP) to the installation we couldn’t be happier. When Brian gave us his personal cell phone number that did it for me. If the VP of a company gives you his personal cell phone number, that speaks volumes to the confidence he has in his products. Carter came back a second time to put our minds at ease with our colour selection. Our installation crew was amazing! Maurice and Brian are top-notch gentlemen who did an amazing job. Having a pool, I was concerned about nails and other debris ending up in it. Well, there was absolutely nothing in my pool. You could tell they took pride in the work they did because they took pictures of themselves in front of our home when it was complete. They seemed proud of the job they did. Maurice kept saying it has to be done right the first time because they don’t want to come back (although they are always welcome to stop by for a visit if they are in the area). We were initially concerned that the roof might be louder when it rains, but it’s actually quieter. Our daughter used to wake up through the night when it rained but now she sleeps right through. It could be because they were able to go right over the existing asphalt shingles which also reduces landfill waste. I never thought I would get compliments on a roof. People walk by and say it looks great. When I pull up to my home I say wow that roof looks good! It’s a premium roof at a premium price, but one shot and you are done.
