I have worked with them for over 5 years and
can't say enough about their customer service,
professionalism, quality of service and
prices. They work with you to come up
with a solution for any roofing problem.
They will come out and give a free estimate
and explain why and what they will be doing.
Give them the opportunity and you will be
glad you did.

I give this company a major big thumbs up! The knowledge and speed of service is fantastic! I am really, really pleased. These are honest, hard working people. Their prices are very fair and they seem to genuinely care about the people they are servicing. They are permanently in my contact list for roofing!

Professional and Ethical Roofer, Whew.

“I SINCERELY thank you for being professional and ethical. I am a teacher and I have to work three jobs to maintain my home. It saddens and sickens me whenever I realize a contractor is deliberately trying to take advantage of my kind nature. I am VERY GRATEFUL that I NEVER have to worry about that when I deal with J&J Roofing. Thank you!” – B.S., Burbank

Utterly Underwhelmed

Hired these guys based on previous recommendations. They were courteous and professional at first. Then one phone call did not get returned. They were apologetic. I said no problem, these things happen.

They came to repair a fairly bad leak in the bathroom of my office. The price they quoted was reasonable.
Due to the sparsity of rain in the region, it's difficult to tell if a leak-repair is successful. During the next rain, the leak reappeared, though not as bad as before.
I called J&J to have them come out and take a look at it. Someone from the company came out to examine the leak. He said it appeared to be coming from somewhere higher up on the roof, but wasn't very specific.
A few days later they mailed me an estimate: an additional $500 to repair the leak. As far as I'm concerned, this is the same leak I had asked them to repair in the first place. I don't really know how roofing works but I do know that if a client had a problem with my work, within reason, I would try to fix it. I don't mind paying extra to cover materials and labor, but they seem to be treating this as an entirely different job. I called the company to get clarification on this issue, and never received a return call.

Now, two months later, it's raining and the bathroom looks exactly like it did before I ever contacted them: a wading pool. I've called them yet again and got the promise that the owner would call me back. Wait & see....

Honest & dependable

I decided to call them based on the other reviews on this site, and I'm glad I did! I have never had as wonderful and easy an experience with a contractor as with J&J. Not only were they knowledgeable and friendly, but more importantly, they were honest people giving fair estimates. I would definitely use them again and recommend them to my friends & family.

An honest family company

To say I was impressed with J&J's service is an understatement. Their willingness to answer any of my questions, the quality of their work and the friendliness and approachability is like nothing I've experienced with other contractors. I own several properties and have had to deal with probably ten different contractors over the past three years and they were the only one who were hassle-free. I had one small issue that I brought up mid the project, and they treated it like it was very important. It's nice to see an honest family company who cares.
