[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.

Jim Carlson – Water Leak Repair in Normal IL

I was surprised at how fast the project went! Nick had everything going both days from about 6:45am until the afternoon. They were very efficient and it was obvious that our roof was in good care. Everyone I spoke with was honest and proffesional and the work was done quickly and expertly. We are very happy with the roof. At one point they needed to fix some siding and they kept me in the loop and got it taken care of right away.
