BUYER BEWARE of Blue Ribbon Roofing LLC, McKinney, TX,. The owner John Hopkins has operated under several different business names: Signature Roofing, Bold Renovations (and variations thereof, ie Bold Roofing), and most recently Blue Ribbon Roofing, who sold me my TPO roof in January, 2018. I have an architecturally significant home with a series of flat roof lines. I contracted Blue Ribbon to replace the existing roof with a Firestone product. Blue Ribbon, instead, installed a different product by Carlisle. They also installed new coping, and retro-fitted (3) skylights. John Hopkins did not inform me of the product change, file a city permit, or provide the subcontractor’s installation license for the installed product Carlisle manufacturer. He said the project would take two days, it took 6 days, and they disconnected my DirectTV, did not pay to reinstall. At the end of the install and final cash payment, John Hopkins assured me all the drains had been address and cleared, trees would be trimmed, and the installer would remove all the trash, clean the site. My roof began to show leaks 4 weeks later, in late February, 2018. I had three flat tires from improper site cleaning (nails in tires). Trees were hanging over roof drains and rubbing against the home, and the workmen unplugged my sprinklers without reconnecting. None of the old caulking had been removed and resealed around the perimeter flashing of all exterior walls, and all the coping had been screwed on the top. The installer did not use the standard clipping system or wood blocking at the top of the parapet walls. Water was pooling, and not reaching clogged drains. In April, Blue Ribbon Roofing cleared the drains, replaced two of the three skylights, replaced vents, and caulked over existing caulk. In May, as they painted the interior water damage, other leaks were detected in the living room, and master bath and closet. Blue Ribbon did not address any of these new leaks by the end of that week. I called the contact number on his insurance certificate that is posted on his social media. The number was disconnected. I sent an email, no response. John gave me the brokers correct cell number, but he no longer represents Blue Ribbon. June, 2018, I hired an independent roof inspector who documented 13 deficiencies in the installation. I had 12 additional issues, including interior water and possible electrical damage. In July, 2018, I made a final attempt for Blue Ribbon to honor their install and warranty. However, my roof continued to leak. After weeks of negotiating, delayed starts dates due to documentation issues and expenses payments, we signed a second contract. It took two inspections for the repairs to be finalized. Blue Ribbon has yet to provide valid proof of insurance. It took eight plus months to get my home to pass a roof inspection, preventing me from selling my home in an aggressive market.
