Customer Reviews

"Working with this company has been 100% impressive. From the first day of the estimate to the last day of payment, I enjoyed every interaction! The men who installed it were so nice and professional, I actually loved hearing them banging around all day! My new metal roof is gorgeous and I even have a few new friends!"
"I highly recommend Jam roofing. I used them to install gutter guards all around my house and to help with the repair of a roof mounted blower motor. They will be the first company I call when it's time to replace the roof or if it needs repair. The quality of their work and professionalism were exceptional at every step in the process. David and Haley were amazingly responsive, helpful and informative in establishing and managing the work. Jimmy and Zach were among the best workers I have had at my home. They are capable, courteous and punctual. They easily solved every technical challenge and left the job site cleaner then when they started. We are fortunate to have a roofing company of this high caliber in our valley."
"I received several bids to have a new roof installed on my house and JAM Roofing was not the cheapest but I decided to choose them based on reviews I read and the professionalism of the sales rep Zach. They completed the job in a very timely manner, cleaned up everyday and my roof looks great. The whole process went very smooth from the beginning with great communication of the project coordinator Haley. In all I am very pleased that I chose JAM Roofing."
