Our Community Speaks Out

“I had a wonderful experience with this company. I received several quotes and they were the most reasonable. They were able to complete the work in a quick amount of time and the staff/workers were very considerate and did a wonderful job. Their quality control director came out later that day to inspect everything and provide pictures of the work. I would highly recommend them!”

“Customer service was EXCELLENT. Called to schedule an appointment and got one the next day. Scheduling was easy. Rick was very knowledgeable and helpful. A few minor things were needed and he repaired them with no charge. He could have easily tried to push some unnecessary repairs but didn’t. I greatly appreciated his honesty. Thank you! I will be calling RoofSmart next year.”
