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 !!

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.

Seamless experience from start to finish! This company came highly recommended by a friend and we’re glad we went with their suggestion. James was able to guide us through the entire process and helped us make an informed decision that fit our roofing needs.

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.


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.
