[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.

Brian and his crew were great — polite, personable, and professional! I also want to thank you for continuing to assure me that if I have future concerns you and your company will be there to take care of them. Right now I am looking forward to enjoying my more stable, secure, and beautiful home, but it is really great to know that you will be there if I need you. It has been a real pleasure working with Brandon. Please let your boss know I will be singing Carlson’s praises to everyone I know!

Karen Mills – Roof Repair in Bloomington, IL

We are very pleased with the work completed on our home. I found Nick Coyle to be easy to work with and the crews that came to perform the work great as well. Work was performed in a timely fashion. When I did have one small issue, of no-ones fault, it was addressed immediately. I would highly recommend Carlson Exteriors Inc. As we define future projects I will be calling on you as well. This was a large undertaking for us, and it went very smoothly!!!

Very Pleased

Jeff Zimmerman – Roof Replacement in Lacon, IL

I was surprised by the effort to seal all possible entry points for water at the front of the house, especially the effort to caulk and seal in the basement. My water problem was my main concern. Your crew was great. I would recommend Carlson Exteriors. Everyone I dealt with was concerned with the quality of the job and pleasant to deal with.
