"There's nothing worse that dealing with pooring rain and strong winds and then hearing the drip, drip sound of water coming into your home due to a damaged roof. I reached out to roofing repair companies through Angie's list and Roofing Pups responded. Marcus came out the next day and put my fears at ease. The bad news was that I needed a new roof. He showed me my options available, categorized as "good", "better" and "best". Despite my choosing the lowest option, he still threw in some discounts and upgrades at no additional cost. I signed the contract and he arranged for someone to come out at tarp my roof. He even went the extra mile of going to Home Depot and setting up buckets in my attic to catch the water still coming in. The roofing crew came out two days later and gave me a beautiful new roof. They then meticulously cleaned the area. It was great working with Roofing Pups. I couldn't be happier and highly recommend!"

"The entire process went very well. The team at JDH is excellent, from their sales guys, to on site managers, to individual workers. All are professional and courteous and take their time to do it right. We've had a few scheduling hic-ups throughout the process, but overall they've been excellent from start to finish. Most importantly, my new roof and skylights look top notch, and will last a lifetime!"

"Worked very hard to get my roof replaced ASAP. I made them aware of our current leaking situation and my worry and they had new shingles and a crew here within 2 business days of me signing the contract and our roof was complete that day. Overall experience from quoting to replacement was easy. They were the lowest bidder out of 4 local contractors. We've had lots of rain since it was completed LEAK FREE!! Would definitely recommend them to a friend."
