Roof City did an excellent job on my roof. They were professional, fast, efficient, and clean. They over- delivered on their promise to do a five- star job in two days, which included all materials and permits needed. They deserve a 10 star rating 🌟 ✨ 💫🌟✨💫🌟✨💫☀️🙌🏾😀👍🏾

The team dis an excellent job on our roof. Carlos and his team are punctual, communicative and kept the worksite clean throughout the project. There was a slight delay in the beginning but the whole process felt smooth and stress free. Alex was generous enough to add in extra service worth $759. Highly recommended, honest roofing work.

They offered a reasonable price for my roof replacement, and overall I’m satisfied with the work. The main issue was that it took quite a while to finish because of the permit process. At one point, I was worried that the roofing materials left at the property might be stolen, so I texted them about it. They responded to my message right away, which I appreciated, and luckily nothing was stolen. Overall, the price was fair, they were responsive when I had concerns, and the project was completed.
