Project: Repair a Tile Roof

“Ron was quick on the draw to call, show up and check out the situation. He provided a no nonsense assessment of the situation and a Johnny-on-the-spot written reasonable quote. As scheduled, Ron & associate came and fixed my roof as promised for the agreed upon price. I will definitely call upon Ron if I have a roofing issue in the future. In addition, I would strongly recommend them to anyone in need of roofing repair.”

At Ron Williams Certified Roof & Inspection we understand that your home is your Castle.

That's why we make sure that after every Roofing job there is no trace of debris left behind in the yard.

Fake Roofing Reviews - Watch Out!

 

I asked Google AI “how is the same roofing contractor rated super high on Google yet the lowest rated roofing contractor on Yelp?

This is what they said so do your due diligence and check those Yelp reviews too because Google is basically saying that a high percentage of their reviews are fake.

A contractor can have different star ratings on different platforms due to differences in review algorithms, user behavior, and the presence of fake or incentivized reviews. Yelp is often seen as more stringent with review moderation, while Google is more accessible, leading to more reviews but also potentially more manipulation or low-effort ratings.
