I recently contacted GenSun for a roof replacement estimate, and the experience exceeded every expectation. Not only were they thousands less than the two other companies I compared, but their customer service was truly exceptional. They provided a clear, detailed written estimate, thoroughly explained every step, and even sent helpful text updates before service day outlining what to expect and how to prepare my home. On top of their outstanding professionalism, GenSun is a generous, community-focused company that genuinely cares. I’ll confidently be recommending them to all of my clients moving forward.

Big turnaround

Originally it wasn't too good. But this company has regained themselves. There's a guy taking care of a piece of my roof that was coming off. So they have totally won me over. I'm impressed that they're doing this. This is true customer service. Thank you so much. Gensun.

I recently called GenSun for a roof replacement.

I recently called GenSun for an estimate to replace the roof on my home as it has been on “borrowed time” for quite a while. Compared with estimates from 2 other companies, Gen Sun was THOUSANDS less. In addition to the pricing, the customer service was just best of the best. Written and clear estimate, everything explained in detail, texts messages before the day of service explaining everything that was going to happen and when, and a guide on how to prepare my home. If all of that wasn’t enough, Gen Sun is a very generous company that truly supports its community. Will be recommending them to all of my clients going forward.

Great Roofing Company GenSun

GenSun Roofing has been a pleasure to work with! Their communication has been transparent and the work excellent. Total cleanup after the job and then a follow up several days later by Coach Jim.

Everything is laid out!!! No surprises

Details! Details Details! From the moment I spoke with Coach Jim all the way thru the end of the project, I was informed of everything step by step. His assistant Lynn is amazing and I am so glad I went with this company. The crew arrived in time, was very professional, didn’t try to upcharge. Everything is so detailed from the quote to the pictures of the boards they replaced to certificate at the end. You will not regret using this company. Very reasonably priced and worry free from start to finish!

GenSun Roofing Professional and Customer-Friendly

GenSun Roofing is the most professional and customer-friendly roofing contractor you can hire. They do not use pressure sales tactics. My husband and I selected them at our own pace. After choosing GenSun, the representatives informed us of what to expect every step of the way until the roofing job was completed. After the work was finished, the crew did a great clean-up job. The project manager emailed us pictures of our new roof as soon as the work was completed. We are happy with our new roof and highly recommend GenSun Roofing.

Best roofing experience

We had a small leak after torrential rains and called them after they were recommended by a friend. We were scheduled within days for a new roof. Coach Jim recommended the best roof color! The guys came out early on the Friday after Christmas after a Thursday rain delay. When we realized our skylight was in bad shape they replaced it with no advance notice. The crew worked until dark and managed to clean up thoroughly using flashlights. Totally professional and our roof is the best in the neighborhood. Highly recommend!

Excellent 10 stars

This company is the very best company that I've ever experienced in about 45 years honestly. The owner was full of integrity, helpful along the way. Answered all my questions, quieted my anxieties, help me make changes along the way that most companies may frown about but they did so without a hassle. The roof was completed in one day using Owens Corning shingles. The crew was pleasant and the cleanup was excellent. I am so happy with my new roof and the price was affordable! Thank you so much Gen Sun! I will use you in the future for other projects! Thanks again. My prayers were answered!🙏💯
