[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 was mostly concerned about the extent of damage to the existing shingles you all had to replace. Not worried about that any longer– if more shingles separate we will either fix those too or I’ll ask Nick to quote a roof replacement.You all are very down-to-earth and I felt completely at ease even asking dumb questions. This is quite different from my experience with other companies. Everybody was early or right on time throughout everything. The quote process was very straightforward. The work was completed on time. All of your guys were pros and the completed work looked great. Please just keep doing what you are doing. I am convinced you folks will be around for a long time. I wouldn’t hesitate to recommend your company to any of my friends or family. You are good folks.

Ron Ferris – Repair in Hudson

I have heard so many horror stories about contractors who take advantage of homeowners by cutting corners to make more money (especially if the homeowner is a single female), asking for 30-50% downpayment, and failing to answer phone calls from clients. AsI visited with Brandon during our first meeting I noticed he was very personable. He was a good listener – making eye contact, really being quiet long enough to really listen, and choosing his words carefully in order to not misrepresent his statements or cause misunderstanding. Secondly, I was surprised (very pleasantly to hear you required no down payment. That was a game changer for me. Thirdly, Brandon’s communications were fabulous! Every time I called him, he either picked up or called me back soon – often within five minutes and almost never more than thirty minutes. Wow! That was huge for me! Fourth Brandon was willing to work with me in coming up with the best plan for addressing the issues involving my home. The project went from a simple siding job to a project that required removing everything down to the studs, installing OSB, foam, and Tyvek, before replacing the siding. the fact that Brandon stayed working with me through all of the what if’s and actually helped educate me about products and ways of doing things gave me a great deal of confidence in both his acknowledgement and his integrity.

I have sung your praises to everyone I know!
