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.
Ok. The truth…..I have never felt more comfortable and have never trusted anyone doing a repair on my house more than Cesar and his guys who repaired my dry rot issues on my house. And Oh my God, was that Aunt Bea disguised as Lisa, Ron’s wife doing all the customer service communications? Anyway everyone, you’ve lucked out if you have read this review. Ron Williams company is All Good.
We've used Ron Williams Certified Roof & Inspection twice in the recent months. The first time was for roof maintenance, cleaning and some necessary repairs and secondly, for replacement and sealing of dry rot fascia boards along our roof line. In both instances, Cesar and his crew arrived on time, worked diligently as a team and left the area meticulously clean after they'd finished!
Cesar did a great job assessing the areas in need of attention, communicating effectively about our current needs, pointing out other potential problems we might encounter in the future, and answering all our questions.
Lisa Williams was my initial contact point and she's very helpful...read full review
