Merrimack, NH — Roof Review — Higher cost of an Interlock roof worth every penny

The higher cost of an interlock roof has been worth every penny

Merrimack, New Hampshire


Interlock installers were great to deal with. They completed the job in half the time that was quoted. The one minor discrepancy I found two months after installation was fixed by an Interlock representative less than twelve hours after reporting it.

The higher cost of an interlock roof has been worth every penny and I’m not even through my first winter yet.

While it does cost more to put on the roof, I think the payback more than covers the extra price

I had an Interlock roof put on several years ago and I am not sure I agree with the statement “more expensive, sure”.  While it does cost more to put on the roof, I think the payback more than covers the extra price.

I am sitting in my attic office, a place that got cold even with heat this time of year, it is warm now.  It stays cooler in the summer as well which saves on cooling costs.

The sales person told me that it would be the case but I really didn’t believe it.  I would buy this roof again in a heartbeat.

We could not be happier with the total Interlock experience

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.

It just shows how professional and caring the company is

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.

The Installation Crew Was Amazing

Dear Interlock,

We are very pleased with the roofing system that we purchased from you.

I have been involved in several construction projects, both commercial & residential and have never witnessed work done so quickly. The installation crew was amazing, they were fast, hard working and neat. it rained, and they did not stop working. During the install, people were stopping, just to watch, and to ask about the roof. They all were impressed.

We still have people that stop and knock on the door to inquire about the roof. a man stopped earlier this week, interested in your roofing system… he should be contacting you. We have been through one winter with the new roof, needless to say… we have not needed to hire anyone to remove the snow from the roof as it slides off effortlessly.

We have recommended your product to people, and should we need a new roof for any of our properties, we would call you again.

We Would Definitely Recommend An Interlock Roof!

To Whom it may concern:

This letter has been a long time in coming.  My husband and I had an Interlock Roof installed in November, 2009 and have been meaning to tell you how pleased we are with the look of the new roof and the service provided by the installers ~ Nazaar and Vitality.  We’ve gotten many questions and compliments from friends, neighbors and passersby.

Both our home and detached garage needed to be re-roofed, with both requiring removal of the old roofing material and the installation of plywood before applying the Interlock product.  We were originally told that it would take up to 2 weeks for the job to be completed.  To our amazement, the job was completed within a week’s time and that included inclement weather!

Nazaar and Vitaliy put in very long days, were very polite, honored their commitments and ALWAYS cleaned everything up before they left for the day.  We have children and a dog and found not one nail in the yard after the job was completed.  Based on this experience and a product that speaks for itself, we would definitely recommend an Interlock Roof!

Best regards,

It looks great and gives our home a new, distinguished look.

Dear Interlock,

I am writing to express my comments regarding the installation at the above address. First, we would like to thank Mike Baldassari for the professionalism he demonstrated during the initial meeting and follow-ups. His knowledge of the product and understanding of our concerns were related in a manner, that novices would understand.

Next, the installers headed by Nikolay were knowledgeable and kept us apprised of the progress during the installation.

Thirdly, I would like to thank Susan and Miranda for all their customer service support.

Finally, the roof is absolutely beautiful. It looks great and gives our home a new, distinguished look. People stop and stare, to admire its’ appearance. Its’ appearance provides a stately, stunning look.

This is our second and final roof at this home, which we expect to last for years, to the next Cassaro generation. I would recommend your company and product to anyone thinking about a long lasting solution.

Again, thank you.

Your not kidding! This is one fantastic roofing material.

Your not kidding!  This is one fantastic roofing material.  I have worked in the sheet metal trade before and understand the difficulties of working with metal.  I would like to say your roofers are true craftsmen and artists.  They worked 3 long days from early morning till evening I was so impressed on how fast it went up.  I realize how difficult some parts of the roof were to do for them then others but your crew kept on going as if no problem was to big.  They were very polite and all ways checked with me about things before starting and before they left to go home.

I am already getting lots of compliments from our neighbors on how great the roof looks.  I feel great knowing this will be the last roof I will ever need and know I can depend on it long in to my retirement years.

I had been thinking about replacing our roof with a standing seam roof for some time.  But my wife & I have seen some that other contractors have installed and just didn’t think it would look right on our house.  When we saw your ad in the paper we decided to check it out and were very glad we did.  The sample you showed us for our house was perfect and our house now looks like it has a slate roof on it.

I am very much satisfied and can’t wait for the first snow fall to see it just slide right off and not build up ice on the edge like it did with the shingles before.

My wife and I thank you and would like to personally thank each and every one of the members of your crew on a job well done.

There is no doubt about it, our new blue Interlock Roof is exceptional.

There is no doubt about it. Our new blue Interlock Roof is exceptional and the house looks absolutely great.

We certainly were very pleased with your installers. Their professional workmanship and their efficiency with which they performed and completed the job was outstanding. They always took the time to remove the excess debris from around the house when they were finished for the day. It’s very refreshing to know that there are still companies who care enough to do the job right.

As we are on a very busy road, we get to see people doing “double takes” to look at our roof. In fact, we gave a brochure to someone up the road from us and you have since installed a new roof for that person. The overall effect is an excellent advertisement for Interlock!

Thank you again for all your efforts, We are so very pleased.
