Read about our happy customers

I am extremely pleased to recommend James Kim’s Reliance Roofing and Siding business. The presentation of the quote, material examples and diligence information were well done and well received. James’s quote was super competitive, and the outcome of the replacement roof was completed on time and as described. There were no surprises. I totally recommend Reliance.

Excellent experience working with Reliance Restorations. Extremely professional and hard working. James was quick to respond to any questions or concerns. He provided a detailed proposal of work to be done. The pricing was competitive. They arrived on time, and worked almost nonstop. They did an excellent job, the roof looks amazing.

James and his team were very professional, came on time, they informed us on any damages, replaced damaged plywood sheets where needed, and cleaned up debris at the end of each day. They also guaranty their workmanship. It was a pleasure working with the owner, James Kim and his crew !!

We had our roofing, siding and gutters replaced by Reliance. They did an excellent job. James is a professional and very easy to work with.


Great overall experience. Reliance was very prompt, professional, and treated my property with respect. Communication was top notch and couldn’t be happier with my new roof. Thank you!

James and his crew performed an outstanding job replacing our entire roof at a reasonable rate.
James was professional, polite, and friendly. The workers arrived on time, completed the replacement in a timely manner, and cleaned the area after they finished. Our roof complements the siding beautifully; we are very pleased.
We highly recommend their services.

The weather conditions in Serving Ambler, PA and surrounding areas are tough on residential and commercial properties. Hot and humid summers, cold and snowy winters, and everything from excessive rain and hail to high winds cause wear and tear. If you’re interested in beautifying the exterior, sealing up the thermal envelope, and protecting the living/working space from the elements, get in touch with Reliance Roofing and Siding. We offer professional services that deliver benefits every day, year after year.
