Highly recommend! We had our roof done on our house and detached garage. From day 1 they kept us in the loop with scheduling, which I really appreciated. The team arrived early and got the job done in one day. The roof looks great!

Customer Testimonials
My wife and I chose GJ Keller & Sons because they offered us the best options and prices for our roofing and siding work. And despite having to deal with the challenges caused by the pandemic, they still maintained their professionalism and worked diligently to get our project done. We're extremely satisfied with the results. I certainly would recommend GJ Keller & Sons to anybody who is looking for roofing and siding work!

The coordination of all the trades, inspections and communication of this longer project was great and... Read more
