[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.

Your company was recommended to me by Ann Baugh and i had full trust in her so i had no concerns going into the repairs. Nick Coyle was amazing! He found the problem right away, was very easy to talk too and very professional! I was also surprised how quickly the repairs happened! I would recommend Carlsons Exteriors to all!

Jake Firkins – Roof Leak in Bloomington IL

Brandon and I went through the job in detail before the work started. He said the crew was very good, but I was doubtful as I have dealt with contractors before. It turned out that Brandon was right. The crew was pleasant and patient with my questions and observations. The foreman, Brian, was extremely skilled and detail oriented and Paul knew his job well. Better employees could not be found in any walk of life. They cared about their work.

My job was more difficult than most- a large two and a half story house with many angles. No other crew could have handled it.

I want to praise Brandon-though I can’t praise him too highly. He is everything you would want dealing with the public.

Additionally, the quality of your people and their work must ultimately go back to Darren Carlson- a very savvy owner.

I appreciated the professional and friendly manner when I called to schedule work. I also very much appreciated the personal contacts made be Nick Coyle before the work so that I was able to meet him at the work site and then he made extra effort to make sure the replacement shingles would match. He also took the time to look into another roof/gutter question I had. You had done work for us previously on roofing a house addition and now this repair on our rental townhouse. I was 100% satisfied with both jobs.
