"I returned home from a conference to discover my boiler leaking, leaving me without heat or hot water and concerned about potential damage. Steve, a highly skilled and friendly technician, clearly explained the scope of work and costs before getting started. He completed the repairs within a few hours, and the system is now working better than ever. I feel secure in my home again. Excellent work and a great overall experience."

"We are extremely happy with A1 Home Improvement. We hired them to install siding on our home. From start to finish, wonderful staff to work with. Joe, our salesperson, spent a lot of time with us and even provided a 3D image of what our house would look like once completed. Tawana and Lisa promptly answered any questions brought to them. The installation team, Jose' and his crew were wonderful and did an excellent job. The guys that installed the gutters also did a great job. Our overall experience was excellent. Our home is just beautiful!"

"The workers were superb. They worked all day long in the most professional, efficient way imaginable, all harnessed in all the time. The roof was tight, extremely well constructed and ventillated. I had an experienced foreign visitor here who had never been much impressed by American workmanship before but she was incredibly enthusiastic about what she saw the Long Roofers doing. They did everything that had been promised, protected the facades of my house and the one next door, cleaned up so that you would never know they had been there and perhaps most telling of all were proud of their work. I could not have been more pleased and would recommend Long Roof to anyone. It was worth every penny."
