Trusted by homeowners, proven by results
Exceptional service and quality. Michael and Jun kept us informed on progress, recommended improvements along the way, and completed the roof in 2 days. It wasn't easy to get on their schedule, but it was worth the wait. Their price was fair compared to other estimates, with no surprises. Beautiful work!

Michael and his brother and crew did a great job replacing 88 years of old roof on our steeply roofed home. They knew what they were doing, had the right equipment and worked diligently to excavate the original layers of roof, prepare the 4x8s and then add the new tiles we selected. They were the most competitively priced, too. I would gladly use them again on another home in the future.

Fast, efficient and excellent service. Our roof has done very well, especially after the surprisingly intense rain that we got last season. Our neighbor is using MNJ Roofing now. Really happy that we could recommend them.

Discovered a leak coming from my roof. On good recommendations I called MNJ Roofing and they were able to adjust their schedule to do the repair before the next rain storm came in. I'm so happy with them. I know they are very busy, but am very thankful they realized how bad a situation it would have been and made accommodations. Good price, fast and efficient work. Have already recommended them to 2 friends and they also are very pleased.

Michael and his brothers are roof experts and have done countless roofs for me and my clients. I work in real estate and have an engineering background. They are excellent at what they do and provide a great value to the community.

They have completed three roofing jobs for me. They are fast and Reasonably priced. They came out within a day to give me a quote and start the project within a couple of days and finish the project in about 24 hours. They are great honest company that I will recommend to anyone

I have had excellent work by this family-run company, recommended by a neighbor. They installed my new roof in 2009, which is still going strong. They are not only fast, efficient and competitively-priced, but very nice people and totally reliable. Highly recommended!!

Outstandingly service and work product. Fixed a leak on tile roof quickly post recent series of heavy rains, and at a very fair price. Will definitely use MNJ again if the need arises--highly recommend.
