The sales process for a new roof was exceptional compared to the 5 other bids we got and the price was fair. The customized the project to meet our exact requirements.
I appreciated working with our representative. Very knowledgable and respectful. Awesome experience!
Daniel was an amazing partner to help us get our roof replaced after a tornado touched down and hail damage. His hard work documenting the damage, working directly with the insurance company and talking us through the process, PRICELESS!!! I was so comfortable knowing Dan was the point person, from product selection and recommendations, the crew that completed the job in 1 day and he was ALWAYS reachable for any questions. I highly recommend Billy Goat roofing and Daniel as the contact.
Andy came out to assess the workmanship on an in-progress roofing and siding job that was being done on our house and garage by another company. Andy was very forthcoming and patient while listening to our concerns, and he pointed out every issue he found and explained why they were problems and what should have been done to keep with industry standards. He took his time to inspect the work that had been done and also took photos of all issues he found. He was able to give us advice on what we needed to do to protect ourselves and advised that we read through laws and procedures relevant to our project and issues we are facing (he provided information sheets with resources). I feel Andy is very knowledgeable, honest, and takes his job seriously, and I would be happy to work with him in the future.
My account rep was great to work with. He was clearly very knowledgeable and took the time to explain everything and answer all my questions.
