We have an older three story building built in 1898 which had a poor roof resurfacing job done almost twenty years ago and was causing us a lot of problems. Many roofing companies did not want to get involved. Tristate sent an estimator who made quick work of the assessment and provided a quote inline with our expectations and a schedule we thought might be ambitious. However, when the time came the Tristate team tackled the problem and were able to complete the resurfacing of our roof in just three days total. The new roof is perfect and has sealed this old building up for many years to come. The staff at Tristate were honest and true to their word. We are very pleased with the results! They even found a leak in our first floor roof that had plagued us for many years. I would highly recommend Tristate to others needing a quality installation by reputable people!
