[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.

Hoobler Residence – Siding Repair in Bloomington IL

I did not have any prior concerns with Carlson Exteriors before. You were recommended to me by a friend. I didn’t have any surprises. the young man who mate the estimate was polite and professional. he explained what needed to be done very well. The work product was good and I am very satisfied. I cannot name anything that could have been done better. The project was completed very quickly.

Your company was referred to us by our realtor, Darren Sheehan, who we trust so we didn’t have any concerns. We were happy with the timlieness of service, friendliness of Nick, and the pictures of before, during, and after that were e-mailed to help us understand exactly why the roof leaked. We will definately be using your company again. Thanks!

Megan Rolfs – Roof Leak Repair in Bloomington IL

No real concerns, felt comfortable with communications and actions taken by Caleb.
Surprises – not really; knew I had some deterioration in door frame. My tech (John, I believe) was excellent! I don’t think anything could have been done better – great work!
I would recommend Carlson in a minute. Professionally done, great communications, with finished project looking excellent.

Thanks again.

Before you started 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 thats the way one likes these sort of things to go. What please 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.
