[un-con-di-tion-al (adj) not limited by conditions]


When Carlson Exteriors decided to start 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 on your home, we do minor repairs. We fix any roof leaks, replace 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.

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. In the meantime, check out this article on Early Signs of Roof Failure.

I would like to say that I could not be more pleased with the service I received from your company. I called you to mitigate my window problem because of the excellent job you did in replacing my roof. Jason Plummer did an excellent job of going over exactly what they would be doing to mitigate the leaking problem I had in a couple windows. And while the work was going on, John Lowe took the time to show me exactly the process that was being done to each window, which greatly helped me understand what was going on. The area around the windows was completely cleaned and any excess materials were taken away when the job was completed. I could not be more pleased with the work that was done and professionalism shown to me while the work was going on. I would not hestiate to use your company again and recommend you to anyone. Thank you for a job well done.

It was done fast and you were easy to work with. You were fast, friendly, and affordable. But most of all, you actually did the job. Other companies told me that is was too mall of a job to do, but your company took care of me.
