His bid was expensive, he probably would have done a decent job but I shopped around and got more work done for much less and with high workmanship quality.

It went great. Was very impressed with the time and effort John Glass put into this relatively small job. He definitely has an eye for aesthetics, which is appreciated.
Description of Work: Replace 12 cracked/split spanish tiles and set with mortar. They replaced these tiles by removing original tiles from garage as the cracked tiles were visible from the 2nd floor landing. They then replaced the garage tiles with new matched existing color as close as possible. They also removed the Direct TV dish from the roof.

You won't be able to find a better company than J & J Roofing. These people are wonderful. They are very capable, professional, reasonably priced and honest. All companies warned us that once they rip off the multiple layers of roofing, they would be able to see how much the wood is damaged and may need to modify then. When the wood was exposed it occurred to me that a company can completely take advantage at that point. The bids don't really matter because a company can give you a low bid and then increase the rate halfway through. Not J &J. They were so honest. The amount of wood that was damaged was only $200. They could have charged me anything but chose to have integrity. Between that and their excellent work, they are my roofing company for life. I highly recommend J&J Roofing Company.

My mother and I recently purchased an apartment building in Los Feliz. A tenant moved out and when putting in recessed lights the electrician noticed that the insulation was pretty moist. On the roof there was an area where it was clear that the prior owner had patched a prior leak. While I intend to eventually replace the roof, I hadn't planned on a full replacement quite yet. As roofs are a big job, I got 6 estimates. I work during the day so I set it up with many of the estimators to come when I wasn't there. I did meet with J&J's estimator as he was one of the first to respond and set an appointment. Everything was very professional right from the start. Almost all the roofers suggested that I do a new roof. Estimates ranged from $13,000 to $28,000. The high estimate came from a roofer based in Santa Monica and was a bit of an outlier which was easy to eliminate. J&J gave me an estimate for both a new roof and a repair. Their full roof bid wasn't the lowest, but it was toward the low end -$14k-15K. What I liked about them was they were one of two that told me that the roof likely didn't need to be replaced right away. I quizzed my contact Matt about it and he said while it would need to eventually be replaced, I could hold off for a couple years and plan it in the summer when roofing prices were generally lower because of customers not needing their roofs repaired because of rain. This he said would further save me money. I trust builders who tell me I don't need to do something when it is in their interest to push me to spend more money. Thus, I went with them to do just a repair of the leak for $680. I haven't been on the roof to look at their work but expect it is fine. I did speak with some other roofers who also got good reviews who I might consider for the full new roof. A person named Chris Parks at George Parks Roofing and Painting spent a good hour and half discussing roofing options with me and had a more competitive bid to do the full job. However, he seemed to think the roof was in worse shape and didn't want to do just the repair. Because of that I went with J&J. In doing the eventual full roof I will reevaluate both, but based on my experience with J&J I can easily see myself sticking with them as they were very professional and still price competitive.

J&J was fantastic! So rare to hire a contractor where everything goes off without a hitch! Both personable and professional, these guys run a tight ship. Two brothers run the company and are fourth generation roofers. Gave excellent advice on risks for leaks, detailed cost/benefit analysis.. and didn't try to up-sell us. They were very thoughtful about our tight finances, and ultimately gave us a fair price. Took them 5 days to do. Punctual and respectful. Answered many questions without delay. Our renovated Spanish tile roof is now perfect! THANK YOU!

Overall it went well. There was a minor glitch, the company would do well to advise owners that the roofers must have access to electricity at all times.However, the company was responsive to my communications and performed as promised exactly to the letter and did not add any unnecessary surcharges and left the premises neat. I called my real estate agent and told her to add this company to her list of recommended roofers.
Description of Work: After 4 great estimates and proposals from 4 Angie's List roofers, I chose this company to re-roof my 1927 house which had been leaking for a long time before I bought it, The roofers replaced the flat area of the roof with new materials, and then removed the tiles, on the sloped part of the roof, replaced the underlayment, and then reinstalled the original tiles. It looks great.

We were very impressed by co-owner's, Matthew Glass, knowledge, honesty and enthusiasm for his trade. He wrote out a very detailed proposal and gave his reasons for each option, being honest when he thought something could be done without or would be "overkill" (for example solar turbines). He spoke to us at length over the phone as well and we would have been crazy to go with anyone else! The workers arrived promptly and completed everything within a day.
Description of Work: We had some clay tiles that were blown off during the heavy wind storm in Pasadena last year, and some that needed to be realigned. We also had them install two 14 inch wind turbines using flame-applied torchdown.

I was trying to schedule someone to come out to my house to give an estimate. I had to reschedule our original appointment twice. I finally nailed down a time when I could meet them and I called to reconfirm the appointment. I was rudely talked to by owner saying that it was costing him money every time I rescheduled. He mistakingly thought I was calling to reschedule but by that time I was over it and did not want to get a bid from them. Most places have no problem accommodating potential customers' schedules. I've never been talked to like that.

Response from J & J Roofing
He cancelled three times on our 35 year inspector, each time too close to the appointment time to reschedule. When he called the fourth time, I did state that we cannot reschedule as I thought he was cancelling. I apologized profusely for not understanding that he was calling to attempt another schedule. He remained inconsolable, which is regretable but I did apologize. A lot of contractors would have washed their hands of him after the first cancellation with no notice, we kept three appointments that he broke. So it is not truly the case that we did not attempt, at our expense (a 35 year veteran roofing contractor master certified on every major installation does not do this for free), to provide him with help. I am sorry that he was upset despite my apology. I do not feel we deserve an F rating for this circumstance and would ask him to review that in consideration of having committed a contractor's time three times to help him, each time cancelled by him.

went smoothly, no delays; covered my car in garage well however, as of Nov 28 discovered that roofing material is layered in my gutter, just partial. I only could reach a portion of my gutter on side of house where I wanted to investigate because when it rained I had a pooling of water in the area.

A representative came out approximately August 15 (I could be off a day or two earlier or later) to inspect and measure to give me estimates. I have never heard from them since. I had explained my time constraints (work had to be complete before 9/12 in order to get my insurance renewed), which apparently went in one ear and out the other. So I went with other company, who set an appointment promptly, inspected, gave me an estimate, answered my questions, and came out with a full crew and completed both the garage and porch areas in one day. No clue what happened to my estimate from J&J.

Our apologies. A bid was sent but due to an error made by one of our people here, it was not sent to an accurate e-mail address. Again, I apologize for this, I would be pretty unhappy too if that happened to me! I hope it goes very well with the work. If I can do anything for you, my desk phone is 323 913 4194, I'm the owner and I'm usually at my desk from 1 to 5 pm (otherwise I'm in the field checking on the installations and repairs).

I thought that they did a good job. I was pretty impressed with them overall, their responsiveness, their pricing, and especially their quality. They did a free inspection, which is quite standard. They were very punctual, and they didn’t try to sell me much of the additional things. They just told me what I needed, they were very straight forward, direct, and they seemed honest to me. I have dealt with enough other roofers, I had one person come out once, and before he even got on my roof, he was trying to sell me a new roof. But these people were not like that at all. The quality of their work was good, I had a leak, and they definitely took care of the problem. They had to come back a day later and do an overall check of the whole roof. My overall impression was that they were a reputable, well established, independent roofing company. I had a kind of old school feeling about them. I could know that they were doing this for many, many years, and they knew what they were talking about.

We needed a new roof on our second home and detached garage. The existing roof was at least 25 years old and the signs were there that we had a leak. Since we were only going to be on site for 8 days, we weren't sure if we could get a new roof on the house and the garage After looking on Angie's List I only called one roofer, J & J Roofing, a week in advance. The office transferred me to Herb and I explained the situation. We made an appointment for the following Friday. Herb was there on time. After taking a look at both roofs, he said he would have a quote for us with two options that same evening. As promised we received the quote later that evening. In order to get the job scheduled and supplies ordered to meet our deadline, we had to sign and fax back the contract over the weekend. After receiving the signed contract, the job was scheduled for the following week and would take two days. As promised the crew showed up on time and finished the job in two days. Both roofs looked fantastic. All debris was removed from the property. They did a great job! Since we were not familiar with the permit process for a roof, Mike was extremely helpful. He was very patient explaining what steps needed to be done to close out the permits. Mike also provided the waivers and release forms in a very timely fashion. He made the whole process very easy and pleasant. All in all, J & J Roofing did a spectacular job. I would not hesitate to use them again and even more importantly, I would definitely recommend them to anyone who needs roofing work done.

I had a lot of damage to my home?s roof from the wind storm that hit the Pasadena area. My insurance company agreed to replace the entire roof, so I had 3 roofing contactor?s come bid the job. J&J came to my house to bid the job. He was very professional, showed up on time, and got back to me with an estimate in a timely manner. He seemed very knowledgeable and appeared qualified to handle the job. I did however choose another contractor because his quote was about 10% more than my insurance company was willing to pay. The contractor I hired worked with the Insurance company directly to get the10% cost covered, and was even able to get a higher quality shingle with other upgrades. Overall J&J was very good to deal with but at the end chose a roofer that worked better with insurance companies.

The workmen arrived as scheduled and immediately started work. They replaced all damaged tile and sealed around the chimney. They even cleaned the back gutters which were difficult to access. After completing the repairs, they cleaned up all broken tile from the hillside. They matched the tiles perfectly, except for the dirt which had accumulated. Unless you know which tiles were replaced, it is very difficult to find the new ones, unlike repairs I have seen on other houses. I could not have been more satisfied with the work performed. I will definitely use and recommend this contractor in the future.
Description of Work: Inspected and repair tile roof after high winds of January. The inspector found several other tiles that were loose and older sealant that required repair. He moved one of the loose tiles so other inspectors (competition) would find/repair it. Since this was a repair that required less than one day of work, and the underlying felt was not damaged, we agreed that the work could be schedule on a day that he could schedule between jobs. Otherwise, he was booked for several months. Due to a family death, we were out of town for all of February and notified J&J to put the repair on hold. When we returned, the inspector call to put the work back on the schedule. We were contacted several days ahead of some rainy weather when the workers could not start a re-roofing job, as we had agreed to in January. The work was scheduled during that period. I chose this contractor from a note I had received on my doorstep several years before, and the reviews on Angie's List. Since I knew I would be in and out of town and the demand for roofers after a windstorm, I did not get other estimates. If this had been a larger job, I would have gotten several estimates, but the estimate was about what I expected it would be.

The overall work was performed very well. They successfully fixed the leak. I trust the company and like the work. However, since the work was performed I've tried contacting them again and I'm having issues with the inspector putting me on the back burner. He consistently wouldn't return my calls. The inspector is unreliable and undependable. I didn't appreciate being ignored.

The original quote was significantly higher than other competitors, however, of all the roofers that came out, Herb was the only one that actually went on the roof to physically inspect the conditions. He also took photos of the trouble areas and included them in the inspection report. Knowing that J & J made the best impression of all the different roofers that came out by being the most professional, physically inspecting the roof, being upfront, and offering to do the work right (e.g. other roofers wanted to leave the existing shingles and just nail in the drip edge, with no lip; Herb wanted to re-do the first row since he wasn't comfortable with leaving a half-shoddy job). The only sticking point was the quoted price, especially since the repair work carried no warranty, as it was a repair, not an installation. Knowing this, I asked for a re-quote with other roofer's quotes as a basis. They gave me a fairer deal that was slightly higher than the other roofers, but definitely worth the quality of work. When the work was actually performed, the job foreman had a copy of all the photos along with some detailed notes. I went over with the foreman just to make sure everything was done as necessary, but it appeared that they knew everything that needed to get done and even offered to help me make my roof vents match the color of the roof so they wouldn't stick out. I must say that despite the price, the quality and thoroughness of the work was worth it. I marked a B for price, just because of the original quote, but with the revised quoted price, it would be an A for sure. I liked the attention to detail and the work put in to re-flash the different vents and pipes was great. The roof repairs look seamless with the original roof, but at least now I can relax knowing that everything has been re-done the right way. Additionally, the co-owner, Mike, checked in once the job was completed to ensure that I was happy with the repairs (just in time for that *one* rain shower we've had all winter). Communication was excellent and I was satisfied with all the people I interacted with from J&J Roofing.
Description of Work: We needed to repair a section of roof from where we removed a small part of the overhang. Herb came out to look at the roof to inspect the condition of the roof and the extent of work to perform. I took this opportunity to also get a quote on repairing some of the pipes and flashing that the previous owners had done. The total work to be performed was: - Repair valley of roof - Add metal drip edge along the modified overhang - Repair vents and pipes as necessary
