William and the rest of the MacDermott crew have always been stellar. Today they found a small slice in our roof that was left by a previous contractor. William completed the repair and resolved our issue. So thankful for quality craftsmanship and a caring attitude.

Steve Carlson

Josh and Dwayne From MacDermott Roofing were very courteous and professional. They came in, assessed and repaired our gym ceiling leaks, and we were able to see/compare the before and after of what was done. I would definitely recommend MacDermott Roofing, and hope that all of their associates are as thorough and efficient as Josh and Dwayne!!

We have had MacDermott Roofing place a new Duro-Last Flat Roof on our home. The company came highly recommended and I would have to say it was one of the best experiences we have had dealing with any contractor in any field.

William G and crew did a great job as always! I've been very happy with everytime we've had Macdermott Roofing out to our various schools at PCCS. They give detailed reports on fixes made, all employees are very friendly, and service is always timely. Im extremely happy I found them and we have continued to use them!
