When we needed a new roof, we received estimates from five companies one of which was Professional Roofers.com. My brother had used this company and he was extremely satisfied with the price and performance. We decided to also use this company. They are a family owned business and a delight to deal with. They were reliable, efficient and by far the best price. I found out that the lowest bid doesn't necessarily mean that the job will be poor. If anything,they did a great job on our roof. I have referred them to several co-workers and they were all happy with their roofs.
