Customer Reviews
Roxane Willis
I am pleased with how easy Ron Williams Roofing was to work with. Staff was courteous. They communicate well and lived up to all they promised. The roof looks great!
Patty Metzger
We've have used Ron Williams Certified Roof & Inspection twice in recent years. One time to reseal roof skylights (2017) and the most recently (Oct 2025) was to replace missing roof tiles, replacement of fascia board due to dry rot and to repair and seal a pool house roofing structure. In both instances, an inspection was done, and a quote was received in short order. Our work was not an emergency, but it was scheduled in a timely manner. Cesar and his crew arrived on time and worked diligently to successfully complete all work within one day and left our property very clean after they'd finished! We would most definitely recommend Ron Williams Certified Roof & Inspection.

Very pleased with the prompt service Ron, Lisa, Cesar & the crew provided to myself & my home in our time of need! With flat roof puddling problems & as first time home owners encountering such issues, we received amazing results with incomparable service. And trust me, I talked to about 5 other local businesses & Lisa made our experience from the start exceptional.
Here’s just one picture of the great work they did. Such true professionals!
