Services we don't offer

They were professional. The price was under our deductable amount which made it obvious that I was not going to have somebody do it but I was going to do it myself. The service person or the estimator who came out seemed knowledgeable and willing to share his thoughts about what needed to be done even though he knew he that wasn't going to do the job.
Description of Work: I got an estimate from J & J Roofing around 10th of December for roof repair.

They came out for an estimate. They were on time and had the necessary equipment to make an estimate (i.e., a 2-story ladder, as I had requested). The estimator explained the options to me. One was a lower-cost repair of a leak around an HVAC unit on the roof, which he thought would fix the problem but was not a long-term permanent fix and therefore they would only offer a limited warranty. The other was a replacement of the HVAC platform, which would be much more expensive. The estimator recommended that I try the lower cost option to see if it fixed the problem, even though it might need to be redone in a few years. I had them do the work. They were punctual, professional and neat. It is hard for me to assess the quality of their work, since I can't really get up on the roof and see what they've done. However, they did stop the leaking and I'm very happy about that.

It hasn't been tested because it hasn't rained but I think he might have been right. He said the roof could last another year or so. I suspect that I might need to replace the roof but it still has a bit of life in it. He was very honest. He was a very nice young man. It is a father and son. I trusted what he said. The price was reasonable. I would certainly go to him for a quote when the roof does need replacing.
Description of Work: I used J & J Roofing because I had a leak in my roof when the rains were very heavy. It was leaking and dripping in my bedroom. One of them came out and inspected the roof. He did a thorough inspection of the roof and couldn't see anything. My husband had done some sealing and he said that he did a thorough job. He said the water was coming in from a vent from the top of the roof. He recommended that we put a plastic bag over it in the winter, which was a cheap and simple fix. He did that and he went around and sealed all the areas that needed sealing and might have been vulnerable.

I was looking for roofing estimates. J&J promptly came out, measured and gave me an estimate. When I asked how many squares ( a measure of roofing) the roof would require and what the square footage was, I was told they couldn't "disclose" that information. When I asked why not -- why they couldn't "disclose" to me, the owner and the guy paying for the job -- I was told some people use our estimates to get other people to do the job. From my perspective, I'm entitled to know. I need to compare in like quantities. If I get three estimates and one roofer says I need 15 squares, one says 21 squares, and one says 17 squares, either there's tremendous waste, someone's buying extra materials on my dime, or someone's not measuring right. (The same thing would apply to sq. yards of carpeting or tonnage for air-conditioning). When I was told they couldn't "disclose" that information, I wrote them off. If I'm paying, I'm entitled to know!

I am sorry this happened. While I personally would have been okay on letting you know your square footage had I bid it, different estimators have different policies on this and I do not micro manage them on such details. You can have five honest roofers measure your roof and all five could be slightly different results. I do hope your project went well in any case.

Everyone I dealt with was a pleasure! Matthew was able to recommend someone to repair my clerestory window (the wood frame had completely rotted away), he even went as far as contacting the repairman and sending him photos of the work that needed to be done. Everyone there was punctual & professional! I highly recommend them.
Description of Work: I have an old mid century modern home that has a flat and slanted roof. I needed to repair some areas of the roof especially around a clerestory window, two fireplaces and some large old skylights. There were also several nails that needed to be removed and the holes sealed. The work was completed by a wonderful team.

It has been good so far. We did an extensive overhaul at their suggestion, but not their demand. I was happy with that. They were punctual. I won't know until down the line but I think that it was fine. They offered me various levels of work that they could do with varying degrees of assurance that one would be better than another. I threw it at my husband and he chose the most expensive service so that we would have the highest degree of protection. They charged what they said that they would charge.

They came out probably five weeks ago for an inspection. They were good and did a good job. The inspector come on time and did a thorough job. He didn’t rush. He was very knowledgeable and personable. When they came to fix the roof they took care of the job. Though it was a small job they still came back and repaired it in a pretty good time.

Description of Work: I had a leak in my and J&J gave me options to fix it short of re-roofing entire roof. As it turns out some patching work fixed the job. They were quick and efficient. I will call them back when I need to redo the roof maybe in the future.

I compared several roofing companies, and selected J&J, as they are highly rated on Angie's List and Yelp, and responded quickly to inquiries. The estimate was done soon after the initial phone call and was similar to other estimates from other companies. What I would get, and what I wouldn't, was explained. The contract was long (a good thing), clearly laying out everyone's responsibilities, and wasn't open to interpretation as were other contracts I had seen. I worked with Matthew, who is smart, personable, fair and responsive- he also understands that his customers don't know anything about roofing... I peppered him with all kinds of questions, and he was always ready with a friendly and direct answer. He worked with the (somewhat difficult) asbestos abatement company that removed the roof, and acted in my interests, rather than his own. His men worked hard. left things as they were, and were friendly and respectful. He apparently can manage the weather too... it rained ended the day before the roof came off, and started one hour after it was on. The roof is great. I'm afraid that I don't have any negative comments.
Description of Work: Put composite roof on 1940's house, and remove and replace flat single garage roof which had some dry rot and leaked badly. Coordinate with an asbestos abatement company who were to remove two layers of house roofing, the top asbestos, and the bottom cedar shingle.

I have an older house with a sloped roof and a flat roof in another area. Neither roof had been replaced in 20 years. In the recent heavy rains the flat roof developed a serious leak. A friend had the same problem and highly recommended I call her roofer J&J. Because my roof had not been done in so long, I intended to perhaps replace the entire roof as a preventative measure. I called J& J and left a message. Then I waited.....and waited....and waited. They did not return my call. I called again, leaving another brief message explaining what I needed thinking perhaps a large roof replacement might produce a response. No such luck. They never returned my calls.

Thank you for your report Member. I appreciate you letting me know about this. We've had hundreds of calls lately due to sporadic rains and forgive me but I don't know which of my guys failed to return your call but I am definitely going to find out so I can correct the lack of responsiveness that you correctly pointed out. If you want someone to still look at the roof, please call us at 323 913 4190, ask for my son Mike and I have already told him that he is to work out getting a technician to you immediately. Again sorry you did not get a call and I do appreciate you letting me know this occurred.

I am writing the following to save you from this company. I did a total re-roof on my own home. It is a 1921 Mediterranean with a mostly flat roof with ceramic tiles around the perimeter. I thought everything was fine until a couple of years ago when I had another roofer roof a small roof over my bedroom. He made some comments about the prior flat job, but I ignored them because I know how that goes. I?ve had a leak in my skylight for some years now, since re-roofing, and just haven't confronted dealing with it....with J & J or anyone else. I asked a couple of licensed roofers to take a look at the detail around the skylight, and to price out a maintenance estimate for my roof. I was surprised that both companies pointed out serious issues in the workmanship, and choices of J & J roofing, who did the original work. One thing in particular; was that they spent time taking all the roofs off and didn't bother to open the scuppers on the inside to match the outlet, so there are smaller holes on the interior of the roof than the exterior. For anyone with a flat roof knows?you need the hole to be big enough so that it is less likely to clog. There were also decorative roof tiles that were just laying there unattached waiting to fall?plus some other items. I decided to give J & J roofing a call, since they appeared to be a ?reputable? company, to explain the situation, and to hear their side. I was shocked at the utter unprofessional-ism I ran into. I called their office, and told the person who answered what I was calling about. Immediately, Mike got on the phone with an attitude?.not a helpful attitude?.an ATTITUDE. At the end of our conversation, he told me he would have Matt call me back and take a look at my problem. Instead, Matt called me back with an even bigger ATTITUDE. I owned a general contracting business with my ex-husband for years, so I know what it is like to get a call from a client with a problem?or a perceived problem. This guy was defensive from minute one, and couldn?t stop telling me what I was saying. He told me that I had roofers come up to ?inspect? his work. This couldn?t be further from the truth, as this was all communicated over the phone. I told him I called to let him know what was going on, and that I was going to end the conversation now and handle it myself, since I could see that he wasn?t even listening. He hung up on me. Professionalism is EVERYTHING!

J&J was by far the most professional, honest and fair of the four roofers that I got estimates from. There were no pushy salesmen (I'm looking at you, Modern Roofing) and the estimator (Rick) was very prompt, thorough, and knowledgeable. There was no hard sell or gimmicks, and the whole process from bid to install was very straightforward. Rick and Blake were always helpful when it came to getting me samples and answering my questions. J&J's bid was comparable to the the other roofers I spoke to, but they offered a 5% cash discount (every little it helps!) The final price was slightly higher than the original bid (by $400) because an excessive amount of dry rot was discovered (and replaced with new wood.) Several months after the job was completed, I called to ask them if I could have a bundle of shingles in case I ever needed some down the road for repairs (there were none left over from the job.) They were very accommodating and delivered a package to my door the next day for free.
Description of Work: Complete tear off of existing roof (three layers of shingles) on approx. 1300 sq ft 1920s bungalow. Repaired areas where dry rot was discovered and installed new underlayment, 30 year composite shingles, flashing etc. An additional 350 sq ft of new roof was also added over new construction in rear of home and blended in with existing house/ roof line. They offer 5% discount if you pay in cash.

Overall, it went ok. I wish I could say it was great, but it wasn't. There was zero supervision on the project, as they admitted to me that people were on vacation, and they were working on another big job. I didn't really notice anyting amiss, until they worked on the tiled part of the house. That's when I first noticed the tiles weren't alligned. I called to ask about it, and they assured me that that's the way it was when using original tile. Ok, no problem. When they finished, I was not happy about how sloppy the mortor on the tiles were; quite frankly, it looked a mess. There were large globs of mortor sticking out, as if the idea of aesthics hadn't occured to them. Specifically, the bullnose on the public side, front of the house looked really bad. I brought their supervisor back, and he agreed with me that it wasn't right. They then re-tiled and motored the edging around the back of the house, garage, and the bull-head. Unforturnately, it was still bad. Instead of fixing the clump of motor on the bullnose, it appeared that they just applied even more mortor on top; poor thing looked like it had a tumor. On top of that, I noticed that one of the downspots had not been replaced when they worked on the gutters, and was just hanging off. I called them back, again, and they DID come out and fix everything to my liking. The roof looks good, and we'll see if it's watertight this coming winter. The only other negative I might add, is that I've been finding roofing nails on my lawn, and in my shoe's; not great for a home with bare-foot humans & dogs. On the whole, i'm happy with the way things turned out. Although I've expressed my concern to J&J that if I was able to see the errors from a laymans point of view, what might I be missing? They were very understanding, and stand by their work. I really hope this is the case, as they were the highest bid, and I accepted it on their reputation.
Description of Work: On my 1922 Spanish home, J&J removed 4 layers of old roofing on the flat part of the house & garage. They replaced it with a new modified torchdown roll roofing; on slopes, they removed and reinstalled tile with a new underlayment. They secured all the permits with the city.

Rick was punctual, thorough and very detail orientated. He did a complete roof inspection. I explained a few problems and concerns from the appraiser . He was quickly able to find the problem, recommend corrective action and also highlighted additional findings which he included in his report.. He emailed the report to me the same day and I subsequently forwarded it.. I also approved their recommendations for the work needed to be performed and was able to schedule the contractual work and completion within the week. If you are looking for a responsive and quality organization J&J roofing is it. Thanks guys!!
Description of Work: While in the process of refinancing a property, Citi Bank requested a roofing inspection on the recommendation of their on site appraiser.The lock rate was fast approaching the deadline and I needed a report yesterday. I looked to Angie's list, read a few reviews and recommendations and quickly selected who I thought would be appropriate. I spoke with a few people at J & J roofing who serviced the property area. The initial phone contact went well and I was referred to Rick who specializes in roofing inspection reports for escrow etc...We scheduled an appointment time. I was very relieved to find an organization that was responsive to my needs and provided the services that I was looking for.

After talking to multiple roofers - most of whom recommended a complete re-roof even though my existing roof was less than 9 years old - J&J came out and gave me a variety of options. They were very helpful and tailored their recommendations to my needs and budget while making sure I understood the costs, risks and benefits of different approaches. After the work was performed I tested the area around the AC and found that it was still leaking. They were back out in days and completely re-did the work, re-roofing a much larger area than the original repair at no extra cost, and then stayed with me to ensure the leak was fixed. After two fairly heavy rainy seasons I can report that the roof is still in great shape. I would definitely call on J&J again.
Description of Work: I had multiple roof leaks related to two different sets of problems in two different areas of my roof. One was related to an addition and improper installation (of the original roof) and the other was the result of a roof AC package installation. J&J recommended a partial re-roof in one area and a repair around the AC unit.

I was having some leaking roof issues in my kitchen and in the garage. I thought it may be time to replace my Cal-Shake roof altogether. I obtained quotes from 3 different roofers and all of them, thankfully, said all I needed to do was some tile repair and seal our vent pipes and chimney areas. J&J came highly recommended through Angie's List, and they also came in with the lowest job quote. They are busy and appointments to come in and inspect my roof were at least 1 week out. However, Matthew came as scheduled and he was able to give us a quote, via email, within a day or two. The job was finished in less than 1/2 day. They cleaned up the area and even put away the tarp I had put on the roof to ward away the water. The test will be how the roof performs in the rain. I received the invoice via email a couple of days later and that was it. I was highly satisfied overall with their service.
Description of Work: SCOPE OF WORK: Using bronze Sikaflex, seal approx 65 broken calshake. Using mastic and webbing, three course seal all vent pipes by applying a heavy, 4 inch wide coating of rubberized mastic, embedding the asphalt impregnated webbing, and then coating with mastic again. This will last many years longer than a normal seal with cheap mastic. Three course seal gable end transition (wood beam). Seal chimney. Clean up work area and remove any work related debris. PRICE: $720.00

I highly recommend them. They did a work for me, and it was great. Everyone is cooperative. The owner of the company is great. The workers were good. They stuck to their quote, at no extra charges. They came out a year ago, and I thought I needed more expensive roofing to be done. He said it was not required. It was pretty amazing to a roofer to do that. The owner name is Bob Seemann.
Description of Work: J & J Roofing did the touch-up work on the roof about a month ago.
