Re-roof of a 108-year-old home is a major process and investment


The Interlock team was a pleasure to work with from beginning to end. Undertaking the re-roof of a 108 year old home is a major process and investment. After speaking to many other roofers, we realized that Interlock offered the best value proposition and we felt like they were going to be able to deliver on what they promised. Our salesperson, John Mondschean displayed his extensive experience in roofing, by taking the time to listen to our goals, preferences and concerns, offering solutions and working with us to achieve the desired outcome.

John was responsive every request and stuck with us even after the contract was signed. We appreciated that he was always available to answer questions, give us updates and even bringing color samples over one afternoon for us to double-check our selection. John embodies integrity and service.

We were aware that due to current market conditions, we might have to wait a while for our materials to be delivered, however Interlock exceeded our expectations and was able to get the materials to us a touch earlier than promised and started the install within 3 days after delivery.

The day the materials were delivered we met Jesse, the lead installer who we worked with throughout the project. Jesse was awesome in explaining all the steps to the re-roof and answering our questions along the way. He took lots of pictures for us and explained how he would address our specific concerns like adding ventilation, condition of the chimney, placement of snow guards and ensuring that the construction didn’t negatively impact our neighbors. It was clear that Jesse has been installing Interlock roofing for a long time and is a true craftsman, who takes pride in the quality of his work.

Jesse and his crew went above and beyond in ensuring that our neighbors landscaping, A/C units and other areas were properly protected. They also ensured that our property was well protected throughout, cleaned up every day and that they left the job site in great condition once the work was finished. We give the crew excellent ratings for the overall job they did on our new roof.

We are very happy with the new roof and have recommended Interlock Roofing to several of our friends and neighbors. It is awesome to have everyone on the block comment on how nice the new roof looks. It really has improved our home’s durability, value and curb appeal.

We would work with John, Jesse and the entire team again!
They delivered on what they promised!

I would highly recommend this company

Dear John,

I wish I had known about the Interlock Roofing System before I put the last new roof on twenty years ago. If I had, I would not have had to replace it again now. At least now I won’t need to worry about the roof ever again because of the lifetime limited warranty with its 50 year transferable and non-prorated features.

When I first suggested to my wife that we consider a metal roof, she was concerned about the noise level during storms. This concern disappeared after the first storm as the noise level was much less than before the metal roof was installed.

Speaking of installation, we were very happy with the way your installation crew did their job. They were careful with our landscaping, cleaned up each day and when they finished and left, the only sign of their having been there was the new roof itself.

The new Interlock roof looks great, and we have been complimented on it by many neighbors as well as people passing by. Our home insurance company was also happy with the new roof and its Class 4 hail impact resistant rating, which will give us a discount on the insurance premium.

We are very satisfied with the entire process of getting a new roof installed. From the initial discussion with the sales representative, the installation crew, and final results, there were no surprises. We will also be very happy twenty years from now when we don’t have to put another roof on the house.

Thank you,
Jerome Sund
