[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.

The two workers did a nice job and were very quick. Cleaned up very nicely as well. I would definitely recommend Carlson.

Han Kang – Siding Repair in Bloomington IL

Last week, another passer-by complimented us on our siding. She said she loves walking by our house and especially likes our choice of colors. We, too, are happy with our siding! We admired your work ethic and are pleased with your craftmanship. We appreciate the consultation time you gave us before the work even began. The fact that you communicated with us during the work and respected our property meant a lot to us. You cared enough about our home to suggest some creative touches, which makes our house distinctive. You exceeded our expectations and we would be happy to recommend you to others.

Willard Woodward – Siding Repairs in Bloomington IL

We were coming off of working with another company where I’d stupidly agreed to sign some asinine contract about our roof. I was concerned that my experience with Carlson would be similar but was pleasantly surprised. Nick was great. Responded quickly, showed up quickly, had them finish the job quickly and was gracious about an extra job we added in installing our new storm door.
