[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 have had bad experiences with previous contractors. Spent quite a bit of time talking with neighbors and researching different vendors. Also tried to nail down specific requirements for my job (leaking brick in chimney, sagging roof area, etc.) I asked how each vendor would address these issues. Your crew was onetime, polite, and professional. Foreman Dave communicated well and answered all my questions. Work sire was kept clean. Fell like all my concerns were addressed and end product looks good. Chris was responsive on the sales end. Crew did a good job. Peace of mind from resolving old roof issues. Felt you were better at listening to my list of concerns and developing solutions than other vendors I talked with. Price was not the cheapest but still competitive.

I had no concerns because you came highly recommended. I am pleased by how well the new shingles match the old. Men worked very steady and cleaned up well.

Connie Burt – Siding Repairs in Normal IL

 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.
