    Great work at a great price! We own a townhouse and originally reached out because of a small leak…read morenear the top floor. After Royal Renovators performed a quite thorough inspection, it became clear that the issue wasn't limited to one area. The project ultimately included roofing repairs, flashing replacement, waterproofing around the parapet walls, and some exterior restoration work where years of weather exposure had taken a toll. What impressed me most was how methodical and easy the whole process felt. Sean and his crew were punctual, respectful of the property, and kept the site remarkably organized considering the amount of work being done. There were no surprise upcharges or pushiness, just great work at a great price. The house has been through the ringer with the weather, but can happily report no signs of moisture. It's a relief knowing the work was done correctly instead of simply covering up symptoms.

    After three years of silence, Royal Renovators finally reached out with an apology -- something…read morethat should've happened long ago. Their work was incompetent, costly, and unprofessional, and despite having our contact information the entire time, they never took responsibility until now. We eventually hired 2BQ Roofers, who found and fixed the issue on their first visit. It's been three years with zero leaks since. Meanwhile, Royal Renovators kept charging us without ever providing a real solution. This was a stressful, deceptive, and exhausting experience. I would not recommend this company

    This here is a review for Jon and the Big Apple Renovators' crew for their roof replacement job…read more(June 2022). What started out as a minor roof repair for a water leak developed into one of my better home investment decisions. As a first-time homebuyer experiencing an ongoing leak, I weighed my options for a roof repair with several roofing contractors. What stood out about Jon and his team was their positive reviews and responsiveness. An estimator came to my home in less than 12 hours for a free quote and more importantly, provided insight to where the water was coming from and options to remedy the problem. Based on my conversations I decided to go with a small, repair job. When the roofers began their work, the situation evolved into something more serious. Inside I feared this all along: that a repair would only delay the water from eventually coming back into the house. And that's when I talked it over in person with Jon. He sparked my inner financier and advised that a complete roof replacement would be a long-term investment for the home and the work would be covered for 50 years under the GAF warranty. I agreed. Unbelievably, his crew of 10 guys showed up the next morning, and like a well-oiled machine, completed the job that same day. Jon and his crew were a pleasure to deal with and I appreciate them fitting me into their schedule on such short notice. I put utmost value in customer service and Jon exceeded them completely. Only time will tell how the roof holds up, but I'm confident if there's any issues, he'll be the first to know and respond. Peace of mind goes a long way, thanks Jon and B.A.R.!

    Jon was the best person to work with for this project. He came and gave me details related to his…read morework and he kept me informed throughout the project. My entire roof had to get redone (luckily the wood was good), but it's a small house. So it was done in one day. They also informed my neighbors about the work before they started (which was great). They did a good job cleaning up. I had my roof done back in June. I haven't had any issues since. I was concerned about an issue but they came in immediately and checked it, and it was fine - I'm a first time homeowner so almost everything makes my antsy. I'm not easy to please, but I'd definitely recommend this company to others for roof replacements.

After discovering a leak in my roof following a big storm, I called several roofing companies, but Genci responded quickly, scheduled an inspection within 24 hours, and provided a detailed and transparent estimate. He just finished a job in Brooklyn and had the materials to repair my roof and with a great estimate. He worked efficiently, and treated my home with respect--no mess left behind and minimal disruption. What impressed me most was his honesty. He even went above and beyond by inspecting the rest of the roof to ensure everything was secure and sealed properly, without charging extra. The repair was completed faster than expected, and the quality of the work is outstanding. If you're looking for reliable, honest, and skilled roofers, look no further. Best Roof Contracting is the real deal.

    (Roof repair/roof leak/fixing valley) I am sorry that I…read moreposted this review late. I promised Bill to post this on 12/8/2021(FYI, I am not getting any discount/money for posting a review). Bill and his crews did a great job of fixing the roof leak! It hasn't been leaking so far after the fix on 12/6/2021. Although they are not the cheapest among the vendors offering to fix the roof, they were very responsive, offered a great quality of work and a 10 years warranty! While all the other contractors I talked to needed at least 2 - 4 weeks before actually fixing it, Bill did the inspection himself and was able to schedule the work in about 3-4 days! His crews, Mario and another man who can't speak much English took just 1 day to install the new valley membrane and finish all the patching. And they cleaned up all the garbage promptly. There were only 2 things I was a little bit concerned about, which Bill promptly and patiently answered. (1) It's a bit cloudy/rainy on 12/6, so I was worried that might affect their work and was wondering if Bill wanted to reschedule. But Bill, based on his experience, assured me that they would be able to finish the work before the rain, and it shouldn't have any impact. (2) It's stated on the contract that the valley roofing material will be "new Firestone roofing with black mineral surface", but eventually what's installed is "Firestone SBS White". Bill explained that the white one would be a better fit because a silver coating is needed for the black one, and with Firestone SBS White, the silver coating is not needed. I am really glad and appreciate that Bill took the time to patiently and promptly address my concerns, and explained everything thoroughly to me! And he is very flexible with the payment methods as well! Overall, Bill and his teams did an awesome job! Thank you very much for the hard work! And I will post an update in 3 months - 1 year if anyone is interested!

They came out the same day, went up on the roof, and quickly identified a small hole that two other companies completely missed. Both of those companies quoted me around $2,500, saying I would need to remove fascia and gutters--without even inspecting the roof properly. Bill White Roofing was honest, straightforward, and saved me from unnecessary work and costs. It's so refreshing to deal with people who truly care about doing the right thing. I will absolutely be referring them to all of my neighbors and will continue to call them for any roofing needs in the future.

Every heavy rain seemed to create a new issue somewhere in the building. We interviewed several roofing companies and ultimately chose NY Roofing because they seemed the most knowledgeable and realistic about the scope of work. What I liked was that they didn't just quote a replacement and move on. We received a detailed proposal, regular updates during construction, and photos showing the progress of the project. They explained why the water was collecting in certain areas and how they planned to improve the drainage at the same time. The crew showed up every day they said they would, worked efficiently, and kept the roof surprisingly organized throughout the project. The best part was there were no surprise charges once work started. The final number matched the proposal exactly. We've had a few major storms since the replacement and the roof is draining significantly better than before.

After multiple failed repair attempts over the years, the board decided to take direct control of the process and conduct a thorough search for a qualified roofing contractor. After a rigorous interview process, we selected NY Roofing for a full roof replacement. From the beginning, their level of preparation and professionalism stood out. They mobilized an 18 person crew along with a knuckle boom crane to efficiently remove debris and transport materials to the roof, allowing the project to move quickly and safely. Our building has a complex roofing structure with a concrete slab deck, which required a more specialized assembly than a standard roofing system. NY Roofing installed a proper vapor barrier to address condensation issues that the original developer had failed to include, along with high R-value insulation to significantly improve the building's energy efficiency. The roof replacement was completed in 2017, and we are pleased to report that in the nine years since installation we have not experienced a single leak. As a board, we take vendor recommendations seriously because they affect every resident in the building, and NY Roofing proved to be a contractor we could confidently stand behind. For any condominium board or property owner looking for a reliable Park Slope or Brooklyn roofing contractor for a full roof replacement or waterproofing project, we would highly recommend NY Roofing.
