[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.

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.

Todd Ethridge – Roof Replacement

We had no concerns. You guys put a new roof on our house 2-3 years ago so we knew we could trust the quality of your work. I’ve recommended you to several people and you were the first ones we thought to call for this latest issue. Thanks for getting to us so quickly!

Your team was out today and I was very impressed with their professionalism and work effort. They not only worked on the immediate problem, but also fixed a couple more issues they saw when they walked the roof. You should be proud of  your team. Here’s to hoping the leak we see and those we didn’t see are behind us. Thanks again.

Carlson had some good recommendations. I really can’t think of anything [to improve], work and communication was as good as I could have expected! Good work, timely and trustworthy.
