[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 just knew I needed new doors and wanted to utilize a door installer rather than go a different route. The doors look nice. Brian, the installer, was great! Even though there were many problems with this job, Chris worked to get the situation corrected.

Brad Glenn – Gutter repair in Stanford IL

Because the house is only five years old, we were concerned that whoever we picked to do the work, it wouldn’t be taken apart and put back together and look good again. They did what was on the order without any problem. The work was done professionally and looks perfect. Can’t think of a thing that could have been better. We would have no problem recommending Carlson as we are confident the work would be done great.

The Alexanders – Siding repair in Normal IL

Before the work started, our main concern was that someone would be cutting a hole in the roof of our new house.  We realize that is needed to install a sun tube, it’s just a little unnerving when someone starts sawing a hole through the roof of the house. Plus a little bit of uncertainty as to what size of sun tube to get, and whether it would be the solution we were looking for.  But we knew we wouldn’t know the answers to those questions until the work was done. There were no major surprises during the work. We originally thought that the outside piece would sit closer to the peak on our roof, however Drew explained that the peak of our cathedral ceiling indoors did not line up with the peak on the exterior of the roof. We appreciated his explanation of where things were situated once he was able to get into the attic and take a look at everything. Drew did a great job.  We appreciated the care he took in doing the work, along with his explanation of what he was doing. We would definitely recommend Carlson Exteriors to others.

Sara Blessent – Sun Tunnel Install in Bloomington IL

I did not have any concerns about your company.  I was just concerned that there might be some other damages under the shingles.  However, there were none so that was good. No, I had no surprises.  Everything went just as I was told it would. I’m not sure I can think of anything that could have been done better.  I don’t know much about roofing so if there were any problems, your team took care of it without bothering me about it.  Much appreciated. I would recommend your business to others.  Most of my neighborhood already knows of your great reputation. I like that fact that you gave addresses around my house of other roofs to look at so I could pick the right color for mine.  That was very helpful. Clean up was great.  The team was great.  I loved coming home from vacation to my new roof and gutters.  Looks awesome.  Thank you
