  • I would recommend this business

It's no secret from my reviews that I go out of my way to patronize family-owned businesses. Big box companies have their place and for some things I even prefer them. Roofing isn't a one-size-fits-all commodity you can buy off-the-shelf, which is why I appreciate Jean and her family-owned business. I've known Jean for 20 years and cannot stress how much I trust her and the attention to detail demonstrated by J and J Roofing.

I contacted J&J via a friend's recommendation. They sent someone out to inspect my roof, it's issue (a relatively simple patch job) and recommend a plan of action. They emailed me a price estimate and description of the work they would do. We settled on a date and time. They showed up promptly. Did the work in a couple of hours and the price was exactly the same as the estimated quote.

We got off to a bad start with the supplier sending the wrong tiles and part of the job was done before I caught it. Matt immediately had the work ripped off and re-started with the correct materials, with apologies.
Each day the crew came on time, and were pleasant and tidy (and no radios or endless chit-chat.) My Craftsman house looks 1001% better with its new roof and it seems to be a perfect job, finished on time, with good clean-up at the end. I wouldn't hesitate to employ J&J again or to recommend them to anyone. My home is 111 years old and the past several months has seen an endless parade of workmen.

Couldn't be happier!!!! You always wonder what you're getting yourself into when you start a big project like this, but this team and crew were amazing. Clean, nice, helpful, fast and efficient. They replaced my whole roof (over 6000sq ft)in less time than they thought and helped cut costs where they could (found a cheaper supplier and used materials that I had when possible).
Never had a problem or issue and I am confident that if anything ever were to arise they'd be there in a minute since they Stan behind the work that they do.

Rob and his team are tops. They were fast and effective, and after I wanted to make a few cosmetic changes to the roof tile, they came right back out and fixed it to my liking.

Our experience with J&J has always been positive.
John Glass has a staff that is professional and efficient. We have found them to be honest and thorough. We have used them for 16 years to inspect and repair any areas fatigued from the high winds on our area.

Needed our sunroof sealed and should have called J & J Roofing. Instead, we had to learn the hard way. When they do a job, they do it right the first time. Glad to know them and will use them first on all future work needed.

These guys are such professionals! And truly, I have had other repairs on other properties, with estimates that were cheaper, however you truly do get what you pay for in this industry! Thankfully Jush was able to get this concept thru to me, and I made the investment... it has saved me THOUSANDS on the long term. So grateful to Jush and his entire team!

What a cool company! They came out gave us an estimate and once approved we got scheduled. They arrived in time and the guy was super nice and friendly. The scope of the job wasn't major but no detail was overlooked and any questions I had were answered as well as shown with pictures, as I didn't go into the roof. I highly recommend them!

Had incredible service from J and J Roofing! Fair, honest and extremely knowledgable. Matt went the extra mile for us. Gave us a free evaluation of our roof that was thorough. The price was competitive. Love that it's a family business. Appreciate that they take the longterm approach of taking great care of their customers and not ripping them off knowing that is the gateway to more work. Highly recommended!

Customer Testimonials

I run a homeowners association. We have more than our fair share of leaks. Every time Matt and his team has arrived to patch or repair our roofs, I've been impressed with the work. The company is also communicative via email and has reasonable charges. I highly recommend their service. I have worked with other roofing companies who are far less professional and provide inferior roof service.


I have known John and the guys at J and J Roofing for a bunch of years. They are great people. They are ethical contractors with the ability to explain things simply and thoroughly so people completely understand their roofing needs. John has always been a pleasure to be around. They installed my neighbor's roof and it was a beautiful job, quickly finished, and they clean up as if they were never there. My neighbor is extremely happy with the job.


J and J turned out to be everything I had hoped for in a roofing company. After some previous bad experiences, the last thing in the world I wanted to do was get work done on my roof.
John showed up and did the estimate. He was on time, friendly and honest. I was expecting the worst, but he came down from the roof with his recommendation and a very affordable price. My neighbor also asked John for an estimate while he was there. We had both had damage from heavy winds. She also liked John's proposal and he wound up scheduling 2 jobs in one visit!
The day of the repair, guys showed up on time and did a great job. After two rainstorms, neither my neighbor or I have had any problems.
I would recommend J & J to anyone without hesitation.


I have used J&J for my roof since the early 1990's - they were the only company who diagnosed and fixed my roof problem. Since that time I have continued to use them for my house and a vacation property. They are truly the Best! I have recommended them to a number of friends and everyone has been thrilled with their work.
