As a professional in the property management business for over 10 years, I have to give credit to the Kirberg Company. We've benefitted from their service for dozens of jobs throughout the years, and we've never been disappointed. Adam Gwaltney is a knowledgeable branch manager and altogether outstanding person. We thank him and his crews at Kirberg for their dedication.

Best place to get your roof replacement. Or just get through another season. Professional quality work.

Our home is nearly 200 years old, much if the roof is slate which was originally put on around 1890, with maintenance done around 1980. We had hail damage to some of the slate, Scott came out and the damage was repaired and he helped us plan for prevention of future damage. We also plan to start adding slate back where it was removed over the years and we are definitely using this company for that! They have a annual maintenance program that we are also signed up for. Prices were very reasonable and the staff that I dealt with were phenomenal!

After having no luck with another roofing company and one roofing company quoting me over double the price of a repair, Scott came by and offered a reasonable price to complete a repair and did great work. Later I needed a new roof and got back in touch with Scott who did a great job again. I'm a single woman, and I've definitely had contractors try to take advantage of that but not Scott or Kirberg. I definitely recommend!

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.
