GoogleMDJ completed an install on our 18,000+ sq ft commercial roof professionally, on time and most importantly on budget. They showed up exactly when they said they would, kept me informed every step of the way and caused the least amount of interruption to our business possible. I would highly recommend them and wouldn't hesitate to use them for jobs larger or smaller.

Lee NguyenGoogle review
GoogleQuang and Ryan from MDJ Roofing Services, LLC did an outstanding job on my 8,000 sqft commercial retail building. After identifying leaks in my existing metal roof, they provided a brilliant recommendation to install a TPO system directly over the metal. They walked me through a detailed, step-by-step plan supported by extensive photos and videos of the process. The communication was top-notch, and the pricing was extremely competitive. I was particularly impressed by the cleanup; Quang, Ryan, and their crew left the job site absolutely spotless. If you want a contractor that combines technical expertise with incredible attention to detail, call MDJ Roofing. You will be completely satisfied

GoogleMDJ has installed several new roofs for me at investment properties over a period of the last 5 years or so. They have always been efficient and have done quality work. They are reliable, responsible, and get the job done quickly. When they leave, there is not a trace that they were ever there, except for the new roof and the knowledge that we were in good hands. They are definitely my "go-to" source for roofing, and I would highly recommend them.

GoogleGreat job, great service, great team created great roof production after job done. Very Hard work, very quick but very professional job done under 97F degree. This is great and best roof company I had been hiring and using in last 12 years for my house and my rental properties. I prefer them to all who needs roof done. But but very “affordable price”. Thanks to read my review.

Michael GerrityGoogle review
GoogleAfter getting quotes from several companies, I chose MDJ. They weren't the cheapest quote, nor the most expensive. I chose MDJ because Michael is a straight talking man. What he said would be done happened as he said it would. The crew did the roof quickly and replaced decking as needed, installed new drip edging, and swapped out outdated vents for a ridge vent. The yard was spotless. The only way I could tell MDJ had been here was that I had a new roof ! I'm glad I chose MDJ ! Thanks Michael and crew !

GoogleMichael and Minh are the best! They not only replaced the rafters damaged by Zeta, they installed a whole new roof with new gutters and leaf guards. Their interior is awesome, the ceiling texture and paint were perfectly matched. They arrived at 7:00 AM as a Tour de Force with ten or so, repaired and roofed my house in one day. My wife enjoyed picking out the architectural shingles.
