Customer Reviews

"Expert workmanship. Responsive and good communication. We have an IB roof. We removed our old brick our chimney in order to install a gas fireplace. New venting meant repairs needed by a certified IB roof installer in order to keep the warranty. We are very happy with the work the roofers did. Highly recommend this company for all your roofing needs but be prepared for a bit of sticker shock. Prices have increased everywhere and Bay Valley Contractors is no exception."
"Not the cheapest service, but high quality job and attention to detail. Had a full roof replacement done. They identified places where the old plywood and beams had rotted and fixed them up without needing me to do anything but approve the extra costs. Site was cleaned up very thoroughly each day and by the end of the job. Raul and Ryan were the project managers and they were fantastic to work with. They handled all of my misc requests ("haul away the old extra roof tiles on the side of the house", "get rid of the weird fiberglass thing over part of the roof", etc.). Awesome job!"
"Ryan was very Knowledgeable and was able to answer all my questions! I highly refommend them!"
