    Beware of this company, Especial for "Roofing" they are doing the job not correctly then you on your own, they get the permit of my house on a difference roofing company's License C-39 and Efficient Construction only have General contract License, something is very wrong here! And the Roofer Carlos had been told me he is employee of efficient Construction. I have to hire a difference Roofing company to finish what they "screw up" and send them the bill, they fail to respond to me on my demand letter for the amount of money I spend to fix they screw up I and up to complaint to "California State License Board" and file a small claim to recoup my loss! Following is conversation of C-39 Contractor & Owen Corning Sale Rep & myself: Hey, Rolando, how you doing? It's Johnny What? Johnny, with Roof Bro. Oh, hey. Hey, come here. How you doing? I'm good, I'm good. Hey, I have a question. Um, I'm over here with a client. Uh, he just had it roof install on a couple of weeks ago. They installed the Owens Corning system and uh, but, uh, I'm trying to explain to him that, uh, like the way they did it, they have the soffits for intake. But they installed a rich fan and they installed O'Higgins and then they installed a solar fan. Okay. So, what happens to the warranty when you have all those 3 systems for exhaust? Are they all for exhaust? Yeah, they're all for exhaust. There're enough soffits for intake, but the exhaust is belonged to me originally. Yeah, that's okay. Yeah. Yeah, so if there's ever, um, anything with the shingle or any pollen with the shingle and it's due to ventilation, then that is where the warranty might be avoided. I'm not saying it is, but it might be voided. So, when you have different exhaust systems, it could complicate the ventilation system in the attic, because you would, so you're supposed to have only one intake and one exhaust. So, uh, or one type of intake which you do at the soffits, and then one type of exhaust, which you have, uh, three. at this point. So, what you would, what you could do is cancel some of them out and the exhaust? Uh, and then you should be able to have a proper airflow in the attic space. Okay. All right. Well, which one should I cancel without? It all depends on what you want. You could cancel out the solar attic van. You could, um, cancel out the O'Hagan, um, or you, that's how it's original. So, it all depends on kind of how you want to proceed. Can I have two? Can I can I have exhaust and uh... You could, you could have the attic fan and then one type of exhaust. The only situation that could occur is that when it rains or where there when there's moisture in the air, heavy moisture in the air, the attic fan could suck in some of that moisture. Um, because of uh, Because of the because of because of there being another exhaust system. nearby. So, it could suck in some of that moisture. So, you do want to be weary of that. So, and that's in times when it's about some rain or when it's raining, just make sure that the attic fan. does not turn on. They sell it so long. It's a solar. It's a solar. Yes, yes, yes. So, you just want to be cognizant of that, but at this point, just, you know, exit out, exit one of the exhaust vents out, whether that's the ridge vet or the Hagan. And you'll definitely have proper airflow at that point. So, if I, if I, if I take the O'Hagan now, that should be fine, right? Yes, yes, absolutely. Because right now, I still have the exhaust, uh, solar exhaust, and uh, Vent, and uh, Bridge vent. So, he's got the Bridge vent. The Bridge vent, Yeah, but the solar fan is like almost, it's really close to that Richmond. So that's going to trap some moisture, right? It's going to suck in some of the moisture. Yeah. Yes, that's correct. Okay. Okay. All right. So, it all depends on how you want to do it. You could cancel out the O'Hagan vents if you want to by putting a piece of ice and water inside the attic, or you could take out the whole thing and put shingles over it. So, it all depends how you want to process.

    My new roof

    We were actually happy when Efficient showed up on our doorstep because we could not remember the last time that our roof had been updated. The representative made a 1pm appointment with us but their sales person arrived much later when we were eating our dinner. Arman checked the wood in our attic and advised all needed wood would be replaced. He provided us with proof of the company's license and liability insurance and status with the BBB, etc. Everything sounded great. They even provided financing and a discounted price. The job took four days, seems quite labor intensive and appears to be done well. There has been one rain so far and the roof has held up great. We have a flat roof so it can be challenging. Prior to the rain, we noticed, we could see light through one of the a/c vents, the roof was installed with blow torches and a hole had been burned in the awning over the back door, the workers used our broom to clean up, voltage wires to our a/c unit and our cctv system were left exposed, the pvc pipe was left directly on the roof, the pvc pipe was disconnected and stained the ceiling in one bedroom after they had removed the old roofing material. To this day, we still wonder why they did this. All the aforementioned items have been rectified except the stain on the ceiling. We reported the damage to the ceiling and have heard nothing and have since had the damage repaired. A city inspector actually signed off on the this roofing job but never went on the roof because there were too many basic things that were done incorrectly like the pvc pipe directly on the roof and the exposed voltage line. We were also home when he was here and noticed he never went onto the roof. Before signing off on the job, Arman and another person visited us looking over our house criticizing our windows advising how much energy we were losing.

    Warning: This is a long one. I bought a house in May and and needed contractor work. I guess they saw us moving in and left a flyer on our doorstep. I called regarding a roof replacement and they seemed very courteous and friendly. The man came at the agreed upon time and he said he would come back when my husband was there so "he could give his input" excuse me? I explained that it's my house and I was hiring him, so everything is with me. He went into my attic and never went on the roof! He left me with a brochure and said he would come back another time when my husband was home. Again, bro? I received another call from Efficient. They asked if they could send someone to give me an estimate and I was like "you already did!" I was told that they weren't aware of that and it was probably miscommunication. I agreed to a new guy to come out. Appt was for 3 PM, he shows up at 3:20 and asks for a ladder. Seriously.... You're a contractor coming to look at a roofing job with no ladder??? He said his wife took his work truck and ladder. We offered him ours and he said " guys, I'm so sorry but my kid has a baseball game and I don't want to miss it. Can I come back?" Absolutely not. We told him we would find another roofer and thanks. The next day he shows up at our house announced! My husband was at work and I told him through the ring camera we did NOT want their services and please leave. He proceeded to leave me a long text apologizing and saying he wanted to make it right and now I'm like "are we 17 and dating??" I told him NO again and please leave us alone. I deleted the text and blocked his number. We got a new roofer who did an excellent job. Every week or so I was getting calls from efficient trying to schedule a roof estimate. I blocked you! The roof is done! Go away! Every week they call from number starting with 310-400 and I realized the guy was texting/ calling me from his personal phone and THATS what I had blocked. My husband called the "owner" and told them to leave us alone and never show up at our house or call again. Today I get two new calls. See for yourself... This company is at the very least unprofessional and unhinged. The hidden review is 100% correct. Beware of Efficient Construction and leave us alone! Don't even respond to this review.

    Interior water damage

    I would bestow a rating of zero stars if it were possible. I find it difficult to know where to begin. Initially, the two representatives who visited my home to provide an estimate insisted vehemently on the necessity of my husband's presence. Despite my explanation that he works extensive hours, their persistence remained unwavering. Once my husband arrived early to speak with them, they entered our home with a box filled with various items, determined to showcase the extraordinary qualities of their proposed paint. They conducted demonstrations before us in an effort to persuade us that they possessed the finest product on the market. My residence is a modest two-bedroom, one-bathroom house encompassing approximately 750 square feet. After indulging us in a masterclass about their so-called magical paint, which they claimed would endure for a lifetime and safeguard the "bones" of our home, they proceeded to provide their estimate. Astonishingly, they quoted us a staggering $51,000.00 for the painting project. However, upon witnessing our astonishment, they began to manipulate the circumstances. They "consulted" with their superior, who purportedly agreed to lower the price if we permitted them to place an advertising sign in our yard. Miraculously, the estimate was adjusted from $51,000.00 to $39,000.00. Observing our evident hesitation, they suggested that, since we seemed to be agreeable individuals, they would once again reach out to the "Boss" to see if he could offer us any further accommodation. With great enthusiasm, they presented us with a final offer of $31,000.00, claiming it to be an unprecedented price and the best available for the high-quality paint they advertised. After a private discussion with my husband, we resolved to inform the two men that we needed to review our finances and deliberate further on this proposition, expressing our intention to contact them the following day. One of them exchanged glances with his colleague and cautioned that the offer was time-sensitive, indicating that if we chose to reach out the next day, they could not guarantee the same terms. Since we lacked the opportunity to acquire estimates from other companies, their manipulation caught us off guard, and regrettably, we allowed ourselves to be deceived. We are still beholden to the financing for that job. Now, the paint is deteriorating, and the wood is damaged. I have repeatedly called and texted them in hopes that they would come and assess the alarming state of the paint and wood they applied to my home, yet they have ghosted me, providing no response whatsoever. I am uncertain of my next steps. I will share photographs of the inadequacies of their work on my property. I urge others to heed this warning about the company; it is truly a dreadful establishment.

We had six different…read morecompanies come out to bid, and while they weren't the lowest bidder, they came in pretty darn close to the lowest bid. Besides price, our other priority was a company that did not use subcontractors, and SoCal Roofing only uses their own employees, so we felt confident moving forward with them after checking out some of the previous homes they'd worked on. From quote to install, the project went very smoothly. They were quick to respond to any questions we had, and the full roof replacement was done in about three days. Timing couldn't have been better, since we got several days of rain a few days after the install, so it was the perfect time to "test" the roof to make sure there weren't any leaks. We were solid. Among all the businesses we've worked with for other upgrades to our home, we can honestly say that SoCal Roofing is one of the only ones where we have felt 100% confident in the work that they did. They are very thorough with their work and you can tell they truly take pride in it. We would happily recommend them to family and friends.

His team came out on time and worked like a machine to complete in one day. They cleaned up after they were done and then the foreman came out same day to inspect and perform quality control.
