We had replaced one roof in the time we had owned our home, and now it was time for the second replacement. I began to wonder if there were any alternatives to old asphalt technology. Also, we had two concerns about asphalt, the first is that it is not clean from an environmental standpoint and second, asphalt is oil based which means its cost is linked with the price of oil. I noticed that many commercial buildings had metal roofs. My wife and I usually do a lot of deep research for major home projects. We began looking into the possibility of replacing the current roof with metal. Our research indicated that there were residential metal roofs available in various metals and styles. Four factors need to be considered.

1. Type of metal. We chose aluminum over steel. It’s lighter and less susceptible to corrosion although corrosion is not a major factor due to the various coatings and treatments applied to both metals during the manufacturing process.

2. Structural assembly. We liked the Interlock method of attaching the panels to each other and the roof base. When complete the system is structurally sound and waterproof.

3. Installation process. Installing a metal roof requires experience. Installation is different from that of an asphalt roof. During our research we had a hard time locating installers that had experience installing residential metal roofs. This was another reason that we chose Interlock. They are associated with installation crews who have the knowledge and experience required for working with the Interlock product. 

4. The only other factor to consider is the style and color, and there are many to choose from. 

Installation was uneventful, the crew was courteous and they explained exactly what they were doing and answered any questions that we had. The roof looks beautiful and we have had many compliments on it since it was installed two weeks ago. We are very happy that we chose Interlock for this project and highly recommend them.

We chose Interlock to install a much needed new roof on our 200 year old farm house in Warner, New Hampshire which serves as our year-round vacation getaway. From the moment David Harrison showed up to meet with us through the final completion of the project a few weeks ago, we knew that we had made the right decision and that our project was in good hands. We never once felt pressured even though we took longer than expected to complete some preliminary repairs to a porch roof before the project could begin. When we did finally call to say that we had completed our work and were ready to go, they had a work crew on site in less than a week! More amazing is that they completed their work of stripping the old asphalt, installing a plywood deck, and re-roofing a large old house where nothing is truly square in five days and, other than the evidence of a brand new gray slate roof on our house, one would never know that anyone had even been there. The crew left our property cleaner than it was before they arrived. They even cleaned up a pile of roofing debris we had left behind following our pre-roofing project. Throughout the project, David and Jennifer, in the office, were always available to answer our questions. From selecting the right roof to arranging financing, to completing the project in a timely fashion, we could not be happier with the total interlock experience. We are highly satisfied with the result and are already looking forward to having Interlock install a new roof on our adjoining barn in the near future.

sammamish-roofing-review 20130923Interlock replaced our old shake roof, which was leaking. It was not more than 13 years old. In life you get what your pay for. I went on line and looked at the choices, and it was clear to me that that Interlock was the best choice for our home. I called them right after I did my research. Where I come from, quality is the most important thing when you are looking to buy a new product, especially something as important as roof. We were really unhappy with our last roof, and wanted to get it done right this time, to last for a lifetime. I can’t say anything bad about it. We love the roof, and the installation was great. The warranty can’t be beat. Ross was a great company rep. I did not worry in the least about the price we paid, I don’t want to do the roof again. The neighbors keep asking us about the roof. I keep telling them, don’t think of anything else but Interlock. We’ll see a few more Interlock roofs in this neighborhood by the time I am done telling everyone about the company and the roof.

Dear Interlock Roofing,

We want to say thanks for our beautiful roof, and the peace of mind knowing that we will never have to replace our roof again. The roof looks great and we just want to show it to everyone.

The installers always kept our property very neat and clean. They worked long hours and were always very polite and professional. The supervisor came to our house to inspect their work and to see if we had any questions or concerns. It just shows how professional and caring the company is.

We could not be more pleased with the way our rooflooks and matches our house. We love the slate look and how maintenance free it will be. Can't wait for our first snowstorm and not worrying about cleaning the snow off the roof.

The neighbors have told us how the roof looks great, and one neighbor could not believe that it was metal roofing.

We are very satisfied and would recommend your company to others.

Dear Dan:

It has been a couple of months since the installation of my Interlock roof was completed, and two neighborhood endorsements have been forthcoming in that period. First, neighbors have commented about how good it looks, and second, they have commented on the daily cleanup done by the installation crew. I heartily endorse my neighbors' comments. The cleanup factor really became evident shortly after when a conventional shingle roof was installed a few houses away by a local contractor. Materials were staged in front of the house rather than out of sight in the rear, and the place looked like a mess until the job was completed.

As you are aware, the design of my house coupled with the prior construction of an addition across the length of the rear presented unusual challenges. While aluminum shingles could be used on the front, the slope of the back required installation of Interlock's membrane roof product. Further complicating the matter was a double roof in the rear with no ventilation of the void between the two roofs. Although you built a ventilation solution into the contract price, hidden construction issues once the work commenced on the rear necessitated redesigning the proposed ventilation solution. This could easily have been an opportunity for Interlock to take advantage of the situation, but the pricing of the change was handled by you and your office staff in a very fair manner. The extensive carpentry that became necessary did, I suspect, add the better part of a day to the job, yet the additional cost was nominal for the effort involved . As important as the pricing was to me, it was just as important and most gratifying to see the carpentry skills employed by the installation crew as they implemented the changes.

The one concern my wife had in going with a metal roof was noise during a rainstorm, and some severe weather has shown that noise is not a problem. Also, as everyone is aware, July broke heat records, yet my homes interior has been more comfortable thanks to the reflectivity of the roof. In conclusion, I am very pleased with the outcome.

It is a great feeling to know that our new Interlock roof has been completed. For 3 years we have looked at our roof and known we had to do something. We contacted Barry from and he responded to our call immediately. We thought the products and the service he offered us were top of the line. We were not disappointed with either, our new aluminium roof looks great on our Victorian house, and the crew installing it did a terrific job. Each day after completing their work they did a thorough clean up of the job site. They were very pleasant to talk to and always explained what they were doing.

We honestly believe we made the right decision on selecting Barry and his crew to complete our roofing project. Now we have a roof that looks great, and is guaranteed for our lifetime.

Dear Sir,

Thank you for sending the package of brochures including Dave Brown's letter explaining the Referral Program.

Please note that the 3-man crew began May 14th and completed the job on the 16th. The crew led by George, did an excellent job. From the moment that they arrived at our home, they conducted themselves in a very professional manner! As the crew worked on the roof, they were fast, efficient and skilled in the operation of installing the materials. There was never any mess as they continuously "cleaned up"! In chatting with the fellows, they were friendly and polite. The entire process never interfered with our coming and goings but we were interested in watching from time to time! A real learning experience!! All in all, we would certainly recommend your company and roofing system as we are very, very pleased with the final result - just prefect!

Thanks again to INTERLOCK for installing a roof which is both long lasting and beautiful.

We have already received many positive complements!

Yours truly,

RE: Eleazor Genge

Eleazor Genge was the foreman of the team of roofing contractors supplied by Interlock Industries (Ont) Inc. to reroof our house at the address above. The job was started in 2011 and completed in 2012 and involved both the installation of a new aluminum sloped roof and a new flat roof
covered by a heavy rubber membrane.

This job was very technical in that the roof was a complex series of dormers set on a steep pitch. There were numerous roof sections that required the metal shingles to be custom cut and several of these sections were curved which required much skill to execute properly.

We were more than impressed with the level of craftsmanship that Mr. Genge brought to the job. His careful attention to detail and his vast knowledge of carpentry and metal work provided us with an absolutely stunning end product. We feel extremely fortunate that Mr. Genge was the
foreman provided on this job and we commend his services to anyone looking to complete this type of work.

Yours truly,

We knew that we wanted a metal roof but simply did not like the long lines that we've seen on commercial buildings. Interlock shingles supplied both the metal roof and the regular shingle look. The bonus is the lifetime guarantee. We can't wait to see how it cools our home this summer.

We are already receiving a lower utility bill. Neighbors and friends are making inquiries. I'm sure you're receiving call and questions. We are completely satisfied.

Our roof was completed last month and I cannot tell you how many compliments we have already received. We feel that this is one investment in our house that will really pay off, because with the Interlock roof there is no worry about how long it is going to last. The quality of this product and the professional way in which it was installed proves that this is a company that cares about its customers.

We have seen other homes in our area getting new roofs and dreaded the mess that came with this type of work. One home even had what we called "the loan roofer" doing the job. One man doing not only to tear down of the roof, but the installation of the new roof. And this was in poor weather when it was vital to get that roof on quickly. But with Interlock we had at least 5 to 6 men on the job daily, working long hours. Our property was covered so that nothing got damage during the tear down and every scrap was picked up and removed by the workers.

We highly recommend your company and are very satisfied with the professional manner of your employees. With our Interlock roof we have security of knowing that this product is completely guaranteed.
