"These guys were great! This project took a while to complete because of weather & tedious nature of having to cut each piece to fit but these guys were good. Kenny, I believe was his name, was foreman and he took every step possible make sure it was done correctly. We had some super hot days to be working on a hot roof but they did it! Any concerns we might of had, they took the time to answer questions and make sure we were happy. The roof turned out beautiful and we get a lot of compliments on it. They are a family owned company with their own employees and take pride in their work. I would not hesitate to hire them again or recommend them to anyone."

"This was the second roof repair I’ve had Accredited Roofing take care of, and once again they did a great job. They showed up early, got the repair done quickly, and made the whole process easy. Steve was very friendly, helpful, and informative, and he always responded right away whenever I had a question. After using them twice now, I’d definitely recommend them to anyone needing roof work."

"Our house had developed an intermittent ceiling rain water leak. We requested an inspection, diagnosis, and repair estimate from several BBB-approved local roofing/guttering firms. Cloverfield responded within hours. Their inspection appeared to be very thorough - inside the attic and outside on the roof. We agreed to have them do the repair, and they completed the work that morning."

Roofing questions, answered by experts

Stripping existing shingles and installing a new shingle roof takes a professional one to two days, and sometimes up to three days for larger roofs. Additional safety measures necessary for steep roofs can extend the timeframe even further, as do added measures, like replacing roof decking or reinforcing your roof structure to support heavier materials like slate or clay.

Unlike wood decks, Trex decking doesn’t warp. That’s one of the key benefits of installing this decking material. Over time, common issues with these decks include hard water stains, mold or mildew growth, and stains from food spills. Thankfully, with proper cleaning, you can get rid of most stains and mold.

A roof can collapse from a leak if the leak is left unattended long enough. A collapse will happen when the structural components of your roof become saturated with water over time. The roof deck or rafters can slowly weaken until they can no longer support the weight of your roof.

The installation may have been done correctly. However, improperly installed gutter guards can easily damage your shingles. Also, cheap gutter guards rarely come with installation fixtures. In the worst cases, they simply ask you to nail the guards in, which would sabotage your roof’s water resistance and thus void the warranty. To be sure, always check with your home warranty provider before making any modifications.

Sometimes. Professionals may be able to remove the old roof and re-attach it when completed, depending on your blueprints. That can help you save money. But this method is not without its risks. Larger roofs may crack during the transportation process. And if the roof is old or has problems, it may be better to replace it entirely. Keeping the old roof isn’t always possible if you are making significant alterations to the roofline.
