About – J and J Roofing Company


Our Story

Through a dedication to excellent workmanship, quality products and honest price estimates – J and J Roofing has grown to be a premier roofing company in Southern California.


J and J Roofing was established in 1993 by John and Barbara Glass. John learned roofing from his father as a teenager, before attending UCLA and moving to Las Vegas.  Moving back to Los Angeles John wanted to help the home and building owners of his new hometown by continuing with the highest level of service. 


John built this Los Angeles roofing company on quality and a strong work ethic. Offering excellent workmanship, quality products and honest price estimates – the company grew to be a top roofing company in Southern California.  J and J Roofing Company offers both roofing repair and new roofing at competitive prices with friendly service and superior workmanship.


Fast forward to 2020 and John is retired. His sons, Matt and Mike now own and run the company. But the fundamentals John established are still the basis for their company. 


J and J Roofing offers a wide range of roofing services from minor repairs to new residential home installations as well as large commercial real estate projects.


They service the community with a variety of roofing styles including shingle, tile, slate, shake, single-ply (TPO, PVC), torchdown and hot tar as well as ultra-reflective liquid silicone and acrylic systems.


We welcome your business and promise to provide each job we do with the highest of quality. 


Tip: The top Los Angeles Roofing companies like J and J Roofing are annually overwhelmed with requests for service during the rainy season in Los Angeles.

So if you have a need for a new or repaired roof it is a good idea to book your project before the October of any given year.  Booking a summer repair or new roof project projects in advance is the most predictable work time frame. 

Happy Customers:

Couldn’t say enough about J&J Roofing and each man involved, especially the repairman. It was very refreshing to receive courteous, quality workmanship.”– J&P D., Granada Hills

“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
