Made a huge difference in my electric use for cooling the house!

June 10, 2024

Not only was the sales process easy, the installation guys were very respectful of my neighbors and my comfort while they were working. Now that it’s done I absolutely love the roof. It’s already made a huge difference in my electric use for cooling the house!

The roofer showed up on time and went above and beyond

June 7, 2024

I had to get an old pipe removed from the roof and required new shingles to be installed where the pipe was. The roofer showed up on time and went above and beyond to get the roof looking like nothing had ever been there.

A long term replacement and upgrade to our pine shakes

June 4, 2024

We recently had a new roof installed in Calgary. We chose the Interlock system as a long term replacement and upgrade to our pine shakes which although maintained a few years ago were showing signs of significant deterioration. Our experience with the interlock office and their installers was great with no significant issues. Work was completed as per the agreed schedule and the workmanship appears to be at a high standard and we are exceptionally happy with the appearance of the new roof. The higher cost may not work for everyone but for various reasons, this was the option we selected. We would recommend Interlock to anyone interested in having a great looking roof that greatly enhances the appearance of our home and promises to provide a long term worry free roofing solution for years to come.

Customer service was great. There was no pressure to purchase

May 16, 2024

We had a lovely experience with the entire team, from our initial meeting to the completed project. Customer service was great. There was no pressure to purchase and we learned alot about Interlock's materials. Installation was fast and went smooth. Our roof looks stunning, we have had so many compliments. I couldn't be happier and am so glad we decided to go with this company. Highly recommend!

I've had an Interlock roof for 12 years and it looks as good as new

May 13, 2024

I've had an Interlock roof for 12 years and it looks as good as new. I'm adding a roof over my deck, and needed some posts installed through the roof. One of the Interlock service teams came out this morning and quickly did a great job. I got what I needed and my lifetime warranty remains in effect. Thanks for the great work.

I do not anticipate any problems for the next 50+ years

February 26, 2024

To whom it may concern I would like to commend you on your roofing products, and your choice employees. I recently had my roof replaced by your firm, I have received multiple compliments as to how nice it looks and enhances the appearance of my home. All your employees have been top notch, honest and genuinely helpful. Ross, your salesman, was great. He did not pressure us, we felt that he had our best interest at heart. He pointed out the options and showed us ways that we could reduce the financial impact. The two installers were Ukrainian. I did not get their names, but they were respectful and very business-like. They took their job very seriously and worked sunup to sundown (10 + hours) for the three days they were here. l did not see them take a break during that time. Lastly, Renee in the office was charged with the task of reminding me of the payment schedule, she did so with a great attitude and friendliness. Our experience was very positive. I would recommend your business to anyone looking for a new roof. Our job was accomplished with minimal interruption to our life. Our home was left pretty much as it was found except, we have a new roof. I do not anticipate any problems for the next 50+ years.

Interlock Roofing is hands down the best!

November 11, 2023

By far the best purchase we’ve made for our home. Patrick and Greg were amazing! Installation was quick and there wasn’t any mess left behind. If you have ever thought about getting a metal roof Interlock Roofing is hands down the best!

Considering the amount of man hours put into the installation, I got a bargain!

August 10, 2023

John M. was the third roofing sales consultant I talked to, and I had two more scheduled. After listening to John explain all the advantages of the InterLock System and materials, I was 95% sold but I thought it might be a little out of my price range. I was going to wait and hear from the other two roofers before I made my decision. John asked me what it would take for me to make my decision right then. I told him, and he made me an offer I couldn't refuse. I cancelled the other two sales rep. meetings. Boy am I glad I did. Considering the amount of man hours put into the installation, I got a bargain! Jessie's team worked from 8AM to 7PM for a total of 8 days to complete the installation during July 2023 ( the hottest July ever recorded ). I don't know how they did it! Jessie answered all my questions during construction, and kept me informed of what would happen next. Some of the asphalt shingles on parts of the roof with a low slope had to be scraped off. The majority of the roof had a steeper slope, and the new metal roof could be installed directly on top. People had warned me that metal roofs were noisy during rain or hail events. Not true! The shingles and underlayment have actually muffled the sounds that I would hear coming from my old asphalt shingle roof. The ice and water shields that were on my existing chimneys and vents were extended farther up each one. Some of the vertical siding was temporarily removed and put back so new ice and water shield could be placed on top of the water and ice shield that was already there. I'm 70 years old so the lifetime guarantee may not mean much, but the ability to transfer to the next owner 50 more years of protection is huge! My wife and I are very satisfied with the quality of materials, and the outstanding installation work done by Jessie and his team. It's too bad that the rating companies only allow a 5 star rating for the best and most outstanding companies. A company like InterLock should get at least 10 stars.

I was impressed with the product and the absence of middlemen between installation

July 31, 2023

Our 18 year house needed something. A local roofer suggested a$ 5 K, roof treatment with yearly treatment of $1000. And a roof replacement with shingles at 60K. We looked into Interlock. I was impressed with the product and the absence of middlemen between installation. And quality if the product. The investment was significantly higher but we were impressed and felt it would be the best choice. The crew was polite and professional. They cleaned up every day as promised As you can see from the picture the roof is beautiful Positive: Professionalism, Punctuality, Quality, Responsiveness, Value Service: Roof installation

I highly recommend Interlock Metal Roofing for the following 4 reasons

April 14, 2022

I highly recommend Interlock Metal Roofing for the following 4 reasons:

  1. We are now proud owners of the most visually pleasing and structurally sound roof I have ever seen.
  2. From the owner on down, every person at Interlock is dedicated to customer satisfaction.
  3. The crews performing the work are top notch, led by great leaders. I have never seen a large crew of contractors work so efficiently and effectively. There was never any downtime as there was always a team working on the project. As the days work came to a close, half the team would begin cleanup while the other half continued with the mission.
  4. Their daily cleanup was off the charts! They used blowers, rakes and a rolling magnet to ensure the worksite was completely cleaned.
I was extremely impressed with the operation from start to finish!

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

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!!!
