About Jupiter Builders & Roofing
We're Jupiter Builders & Roofing, a general contracting company rooted right here in Hawthorne and working across Los Angeles and Orange County. What we do is straightforward: complete roof replacements and new ADU construction, both attached and detached. We handle the whole thing from the first conversation through planning, permitting, construction and final inspection — so you're never left holding a piece of the project you didn't sign up for.
We're a local company in the truest sense. We were started here, we work here, and we're raising our families in the same neighborhoods we build in. When you hire a contractor from down the road, you're hiring someone who has to stand behind the work long after the job is done — and that accountability matters to us. We'd rather earn a good name in our own community than chase work we can't stand behind.

Great company to work with, after much debate and negotiations with a few other competitors i landed on jupiter. The process and communication were extremely better then previous contractors i have used in the past and will look to them on future home renovations. Masud was my point of contact and returned all my phone calls and answered late at night sometimes for some follow up questions. I was on a strict deadline for a graduation party to be held here and they actually finished a day ahead of schedule. Great team to work with.

Mr. Ali and his team did a great job on our new white roof. The workmanship was excellent, took 4 days like they said and the finished product looks amazing. Highly recommend this team
- ★★★★★
Jupiter Roofing did an amazing job on rebooting my house. We had an artificial slate installed on our roof and they had the expertise in doing the job right. Their detail, efficiency and easy communication with the staff was truly outstanding! I have many times since they have finished, the job recommended Jupiter Roofing to others looking to have their roof redone. I highly highly recommend them! Jason bahret.

FAQ
Questions, answered
Straight answers about Jupiter Builders & Roofing. Don't see yours? Give us a call.
Call (310) 954-2008Which areas do you serve?
We work across the South Bay and nearby parts of Los Angeles and Orange County, including Hawthorne, Torrance, Redondo Beach, Manhattan Beach, Hermosa Beach, Palos Verdes Estates, Rancho Palos Verdes, Gardena, Carson and Long Beach.
Do you repair a small leak or just do full replacements?
We focus on complete roof replacements rather than small patch jobs. If your roof is failing and needs to be torn off and rebuilt, give us a call at (310) 954-2008 and we'll take a look.
How does a project start?
It starts with a phone call to (310) 954-2008. We set up a time to come out, look at your roof or your ADU site in person, and talk through what you're after before anything is quoted.
How do I get a price?
After we've seen the job in person, we put together a written proposal that lays out your options and hand it to you to review. We don't price a roof sight unseen.
My roof is leaking badly. What should I do?
Move valuables out of the way, catch water where you can, and try to cover the area to limit damage. Then call us at (310) 954-2008 so we can come assess whether a full replacement is the right fix.
What roofing materials do you install?
We install several systems rather than pushing one product, including shingle in a range of colors and styles, tile, low-slope options and cool roofs. We'll match the system to what your roof actually needs.
Can you build an ADU on my property?
Yes. We design and build both attached and detached accessory dwelling units, and we manage the job from planning and permitting through construction to the final inspection.
Will I know what's going on during the project?
Yes. We explain each part of the work up front, answer your questions as they come up, and give you ways to reach us so you always have a point of contact.
