Comments: Janos was excellent the whole way. He responded quickly to my initial request and came through on everything he promised - including scheduling and communication. The work was done quickly and very well, and they even went the extra mile to complete a repair somewhat outside of the original scope.

Review Date: 03/16/2015 | Author: Brian O., Granada Hills, CA

Comments: Owner showed up himself promptly to give estimate-written proposal quickly emailed to me. Owner and workers arrived on time and completed job in two days. They cleaned up after each day. Very happy with the 'look' - all tiles matched and pipes sealed and painted. Overall, a highly professional job at a reasonable cost. Would use them again and recommend to anyone.

Review Date: 03/06/2015 | Author: Sevy D., Los Angeles, CA

Comments: Being on the board of our Homeowners Association, I was in charge of getting 3 estimates for roof repair and maintenance of all 12 Townhomes. Jo roofing was the fastest to come look at the job, the first one to submit a very professional written estimate, and their price was on of the 2 lowest. Out of all the companies I interviewed (4 total), Janos, the owner was the one that gave me the best feeling of knowledge of the craft, and caring for my roof as much as he cares for the reputation of his company. Once we decided to hire him, he made time during a busy December (close to holidays) schedule. Just as promised, they finished the entire work in 3 days, and it came with a warranty of 3 visits if any unit has any problems. You cannot beat that. I highly recommend him.

Review Date: 01/13/2015 | Author: Delia S., Granada Hills, CA

Comments: JO Roofing was outstanding in repairing and fixing a hole on the main roof and added metal flashing to a leaking storage shed.

Review Date: 08/20/2012 | Author: Jeremias J., Northridge, CA

Comments: The repair work done & service by JO Roofing was outstanding. Janos, the Owner, showed up on the day I called Service Magic. He gave me me all the options to repair my roof, all the pros and cons with each of ther options. He was a VERY nice guy, a true professional and very upfront. Highly recommendable.

Review Date: 08/12/2012 | Author: Barron A., Canyon Country, CA

Comments: JO Roofing is an exceptional contractor. He called right away, came right out and gave me a very fair quote. I received 2 other quotes one from a local company that was close to J.O.'s and another from Roof Rx that was over 3 x's J.O's quote. They went above and beyond fixing anything on my roof that they felt wasn't right, did a great job and I have the pictures to prove it. I would use them again and recommend them to all.

Review Date: 08/10/2012 | Author: Denny T., Pasadena, CA

Review Date: 02/14/2012 | Author: Marvin R., Calabasas, CA

Comments: Based on what I observed it appears that the project was done right. They arrived on time as promised, cleaned up after the project was completed. The test will come after it rains and how JO Roofing handles any warranty issues should they arise. My experence with JO Roofing was very positive and I would refer them to my friends.

He showed up on time, worked quickly and efficiently, completely cleaned up, and even did some repair work on an adjacent window. His price was very fair (we had several bids) and he is a very nice, pleasant man. In every way, I would highly recommend him and his company, and if I ever need work done on my roof, he is the only person I will contact.

Comments: No comment.

Review Date: 08/16/2011 | Author: a Neighbor, Porter Ranch, CA

Comments: Did what seems like a solid job [you can't really know until your roof goes through several winters]. Good price. Honest man - how do I know? I wrote my check for more than the agreed price and he CALLED ME several hours later to say I overpaid him! I said "no, that's a tip!" Unless my roof reveals some major flaw this winter, I'll use him from now on for maintenance.

Review Date: 08/12/2011 | Author: a Neighbor, Santa Monica, CA

Comments: Showed up and did what they said they would do. Easy to work with.

Comments: Janos does an excellent job at a very fair price.

Review Date: 07/12/2011 | Author: Charmaine F., West Hills, CA

Comments: Had a great experience with this company. Janos responded quickly by phone and email and immediately came out to look at my roof. The job was done fast and efficiently. When it was all done they cleaned up so well that there was no evidence they were ever there (besides my new roof). The customer service was exceptional and the price was very reasonable. I will be recommending this company to others and I will call J O for any future roofing needs.

Review Date: 06/27/2011 | Author: Regina T., Thousand Oaks, CA

Review Date: 05/06/2011 | Author: Bruce M., Oak Park, CA

Comments: Mr Osazszy kept me informed about everything going on with the roof repairs to my home. He was knowledgeable, prompt, and courteous. He and his workers cleaned up at the end of each day as well. I wouldn't hire anyone else for roofing work, now that I have someone trustworthy.

Review Date: 04/23/2011 | Author: Marian J., Castaic, CA

Comments: Mr. Janos was on time for appointment and came to do the job on time and completed the job on time. Very efficient and saved me time and trouble.

Review Date: 04/22/2011 | Author: Dariush Y., Beverly Hills, CA

Comments: Jonas and his group were on time, delivered what was agreed in the initial conversation. He is a very customer service oriented person, kind, courteous, and knowledgeable. He went beyond of what was promised to me. He is a very honorable individual.

Review Date: 04/17/2011 | Author: Larry Z., Studio City, CA

Comments: Janos is a friendly and courteous roofer who seemed very honest and professional. The repair was completed promptly and reasonably . Since it hasn't rained again, we don't know if the repair actually solved the problem. But Janos does guarantee his work.

Review Date: 04/12/2011 | Author: Chris R., Tujunga, CA

Comments: Showed up right on time for the evaluation and gave me a quote for the job. Showed up right on schedule to do the job. No sudden changes to the estimate. In short, a total pro company. Almost a miracle these days.

Review Date: 04/05/2011 | Author: Linda S., Moorpark, CA

Comments: I was really impressed with how quickly they came out to look at the job when we had our roof leaking in different areas of the house and they where here to actually do the work within a day or two. The prices where fair and they appeared to have corrected the problem but we'll see when the next rain comes. Fingers crossed but we loved them.

Review Date: 04/04/2011 | Author: Denis K., Alhambra, CA

Comments: Great communication. Did a good job and the price was good too.

Review Date: 02/25/2011 | Author: a Neighbor, Woodland Hills, CA

Review Date: 02/25/2011 | Author: Kirk D., Sherman Oaks, CA

Comments: Did exactly what he said he would do to fix our roof. Easy to communicate with. The price was fair, but not low. I strongly recommend JO Roofing.

Review Date: 01/29/2011 | Author: a Neighbor, Los Angeles, CA

Comments: He did an excellent job for me. He gave me quotations estimating the costs in different circumstances: repairing the damaged area only, replacing the foundation for damaged half of the roof with replacements of broken tiles and doing over the entire roof with replacements of broken tiles. He was courteous throughout and finished the job as expected. I would recommend Janus to my friends and relatives.

Review Date: 01/17/2011 | Author: Philip P., Glendale, CA

Comments: Janos was timely and did a great job, he did what he said he would do even sooner then he said he would do it. We were very happy and praise god our house does not leak so we will use him again when necessary

Review Date: 05/30/2010 | Author: Leonard S., Canoga Park, CA

Comments: They are the best! Prompt friendly service and reasonable prices.

Review Date: 04/23/2010 | Author: a Neighbor, Northridge, CA

Comments: Provided quick and reasonable estimate. He was hired to come back to do the work which he did in a timely manner.

Review Date: 04/22/2010 | Author: William F., Valencia, CA

Comments: I was first impressed with the immediate (like, two minutes) response when I submitted the project information to Servicemagic. Janos came out that day to give me an estimate, which I accepted - very reasonable. He spent a lot of effort trying to find the replacement roofing tile to match my existing roof. The tile was delivered a week later around 10 AM, and Janos came out that morning and repaired the roof. Very efficient and very dedicated to doing a good job, I would hire him again when I need to reroof.

Review Date: 04/09/2010 | Author: a Neighbor, Valencia, CA

Comments: got great service at cheaper price.

Review Date: 04/08/2010 | Author: a Neighbor, Los Angeles, CA

Review Date: 04/01/2010 | Author: Sabrina G., Van Nuys, CA

Comments: Janos was fantastic! He went on the same day and looked at our roof and gave me an estimate and took photos. I will not only refer him but will hire him for all my projects. He's also very professional and responsible, unlike most contractors. Thank you, Janos.

Review Date: 03/31/2010 | Author: a Neighbor, Thousand Oaks, CA

Comments: Janos called right away, was very flexible in scheduling a time to look at my project, arrived early, gave me a fair bid on the spot, and did a great job.

Review Date: 03/30/2010 | Author: a Neighbor, Castaic, CA

Comments: Our experience with Janos was what you want in a repairman but what you rarely get; on-time, corteous, listened to what I had to say and humbly offered his opinion. I didn't feel as though he was speaking down to me and he explained what he would be repairing in words that I could understand, prior to getting started. He works well and works efficiently!

Review Date: 03/24/2010 | Author: Fred L., Canyon Country, CA

Comments: Janos was on time for my estimate. On time to do the job. Fair and square with the bid and took the time to show me what had to be done to remedy my problems. It was a pleasure having his company do the job. If I have anymore leaks, I'm calling JO Roofing.

Review Date: 03/18/2010 | Author: a Neighbor, Simi Valley, CA

Comments: They were on time, and did the work in accordance with our agreement.

Review Date: 03/16/2010 | Author: a Neighbor, Sherman Oaks, CA

Comments: Responsive, prompt, courteous, reasonable.

Review Date: 03/11/2010 | Author: Lee E., Van Nuys, CA

Comments: Excellent experience, Janos was very easy to talk with , friendly and professional. He did my roof repair on our first house and very happy with the results. He even had me go up on the roof when he was done and showed me what was done and pointed out the spots that were fixed. I would defiantly recommend.

Review Date: 03/11/2010 | Author: Joan W., La Canada Flintridge, CA

Comments: You gave me two roofers to contact. J O Roofing called back immediately and made an appointment to come over. The other roofer listed by your service, never called me back. J O Roofing did the repair and charged me a fair price. He was very nice and explained everything to me. He showed up on time. I am happy because I no longer have any leaks. My Handyman tried to fix my roof several times, but J O Roofing was successful. I will happily call them again.

Review Date: 02/16/2010 | Author: Scott T., Los Angeles, CA

Comments: Very responsive, flexible, honest, friendly. Called me immediately on Sunday morning after the rains, came out and gave me a quick inspection with fair pricing, but also worked within my budget. They were very communicative in terms of scheduing, showed up exactly as promised, and did a great job...also they share pictures to show me the results of their work. Very satisfied, and would highly recommend them to my friends.
