[un-con-di-tion-al (adj) not limited by conditions]




When Carlson Exteriors started offering residential roof replacements, we knew that we wanted to offer a different kind of roof. An Unconditional Roof.

So, what does an “Unconditional Roof” mean?

We have partnered with CertainTeed to give you a worry-free roof. CertainTeed guarantees the cost of a roof we replace for up to 50 years – 100% NO PRORATING! This warranty will cover the cost of materials and labor to tear off your roof and replace it over the next 50 years. No fine print. No loop holes. When we are done we will even send you a transferrable certificate as proof. We always stand behind our labor and now we have a manufacturer that stands behind their product.

Besides completely tearing off and replacing the roof, Carlson Exteriors performs minor roof repairs; fixing any roof leaks, replacing missing shingles with best matched shingle, clay tile roof repairs, and any other miscellaneous roof repair.  We replace and repair flat roofs, low slope roofs, and rubber roofs. Visit the page about flat roofs and low slope roofs.


Carlson Exteriors gives free Roof-Life Expectancy Evaluations. If you think your roof might be on it’s last leg and might be time to replace it, give us a call and we will come out and let you know how many years we think your roof has left.

I had used Carlson several years ago so was comfortable using you all again. I was impressed with the prompt and clear communication (you are good :))  I really can’t provide anything to improve on – Johnny did a nice job. I would recommend you – due to prompt and professional communication and quality of the work.

Amy Sauder – New Roof in Germantown Hills, IL

We have worked with Carlson in the past on our roof and were very pleased.  We were not concerned about the porch. After the first day of the project, we decided we needed to make a minor change to the top trim board.  Ricky was very flexible and did a great job including our changes. I really can’t think of anything to improve.  We appreciate your services. We have now used Carlson on two home projects and would highly recommend to anyone.

Jessica Ryder – New Roof in Bloomington IL

Before working with you, I had the usual concerns about getting ripped off or shotty work, but we did our homework, asked around, and chose Carlson in the end. There were no surprises, really, and that’s the way one likes these sort of things to go. What pleased me most about Carlson is the complete lack of BS. I talked to Nick about the job. He was easy to work with, and there was no grand sales presentation, which I appreciated.
