I'm a senior and was totally lost in the process of replacing my roof. GenSun was so helpful and reasonable. Their expertise led me through the process, made my decisions so easy. I love the look of my new roof, the neighbors all complimented the workmanship.
We certainly pay close attention to our Seniors! Glad you approve of our workmanship.
Top Notch service.

Thankyou for your comments about our knowledge and our process.
The experience was outstanding. Jim was a true professional and ensured that the GenSun roofing crew was clear on all deliverables and expectations which were met. The roofers were on time, extremely hard working, polite, and cleaned up as well as possible.
John, it was a pleasure working with as well. Your desire to learn about how we install roofs, the warranty, and our attention to detail was greatly appreciated. Some homeowners think that a "Roof is a roof" and doesnt matter who installs it. They are sadly mistaken.
GENSUN WAS A PLEASURE TO WORK WITH. PRICING WAS BETTER THEN ANYONE ELSE WE RECIEVED QUOTES FROM. THE ROOF VISUAL WAS VERY HELPFUL. EVERYTHING FROM THE ONSET TO THE QUALITY OF WORK TO THE CLEANUP OF MY PROPERTY WAS VERY PROFESSIONAL. THE WAY TO GO FOR YOUR ROOFING OR SIDING JOBS.
Yes, you are correct...the Roof Visual is a huge reason why many homeowners use our company. It is a great experience to see what the roof looks like before we start the installation. Thank you
Gensun Roofing came recommended from a mutual acquaintance. Jim came out quickly to give an estimate for my house in Philadelphia. After accepting the quote we scheduled a day. They showed up on time, completed the work and even left the site clean! I've since recommended them to several friends in need of a new roof.
Thanks Matt
