Unique does good work. I met Kyle 7 years ago at a closing and have gotten to know him and his brother Colt well over the years. I have seen their work first hand. Definitely recommend using them!

Unique construction came out and quoted a few remodel items for our home renovation and was very fairly priced and super professional. The. work they did is great and we are happy. Update: Worked and been friends or years now. Kyle and Colt are of the upmost character and customer service oriented. It has been a pleasure working with them over the years. We have done 3-4 transactions now!

Why Hire an ARCO-Accredited Roofer
The difference between "good enough" and proven excellence. Only the top roofers in America earn ARCO Accreditation — recognition of true craftsmanship, ethics, and integrity.
Homeowner Benefits
-
Peace of Mind: Every ARCO-Accredited roofer has been checked against public licensing records, safety records, complaint history, and verified customer reviews.
-
Work You Can Trust: ARCO's evaluation includes manufacturer certification programs — credentials that can help preserve your roof's warranty coverage.
-
Verified, Not Self-Reported: ARCO's findings come from government and third-party sources — state filing offices, SAM.gov, OSHA, and the BBB — not from paperwork a contractor submits about itself.
-
A Public Paper Trail: Every accredited profile publishes its report number, evaluation date, and sources — so any homeowner can independently verify the findings at RoofingContractors.org.
