There are so many roofing contractors in Riverside, CA but a friend of mine told me about Corona Coatings Corp. He told me how good they were so I figured i`d give them a shot. Right off the bat I was blown away by how well they knew there job. When we had the contractor come out to give us a quote, you could tell he was not trying to get every penny out of us, he was fair. He showed me the 3 brands of shingles they had and that he said even their cheapest ones were really strong. He explained to me in full detail what they had to do to re-roof our home, they even told me to contact our home owners insurance to see if they would cover the cost due to the storm damage. I would never have thought of that, thanks Corona Coatings Corp.
