Recommended Customer Reviews
Barry O.Champion gave me an excellent quote on a complicated
steep roof and followed up with an excellent job in a timely manner. They kept me appraised of all the steps
and kept the work site clean and safe. The roof looked great when they were done!
Our 1950's home needed a new roof really bad. We compiled a list of licensed roofers that serviced Ontario and received quotes from 4. Champion Weatherproofing was the only one to respond quickly, show up for the estimate walk through right on time and gave us a thorough estimate complete with before photos. For these reasons, they were the company we selected. A bonus was they were also one of the best priced.
During the work, they showed up right on time again and cleaned up everyday. Upon completion, they provided another report with completion photos. The work took 2 days. Adriana and the entire staff were A-class professionals from start to finish.
Five stars for work and service. Would highly recommend and will use again for any other roofing needs.
Outstanding experience! Any issues that came up where addressed promptly and professionally. We are completely satisfied!
Beautiful new roof! Great working with Javier.
Danny C.Champion is very efficient in their services and the fact that they came to give me updates throughout the service is awesome. They were quick for such a big job and did such a good job in replacing the previous roofing. All of the employees were very nice and did a lot for such a big job. 10/10 would call the again.
Roslyn J.Champion is our go-to company. This is the second time we have used them. They arrived within a day to assess the damage; we had a quote within 4 days. The crew was on time and finished by mid-afternoon. Our final invoice has photos for our insurance company. The price is reasonable. All phone inquiries were returned within 24 hours.
Competitive prices. Very quick and professional. I called and Javier had a complete estimate the same day! They came out the very next day at 7am and completed my roof project by 2pm! They hauled away the debris and cleaned up. I loved the job they did on my roof repair and replacement of damaged areas. I highly recommend them and will keep them in mind for future roof needs.
Carla P.Don't bother wasting your time! I wish I could give them zero stars! This company is a joke!! They were scheduled by our property management to do a simple task of putting up a tarp on the ceiling due to a leak from a busted water pipe. In a 3-week period, I had to schedule 4 appointments for them to finally come out. Out of those 4 appointments made, they were a No-Show to 3 of them! Not a courtesy phone call or any apology, nada. The day they finally graced us with their presence, they were late and rang our door bell multiple times in a matter of a minute (might I add, I have 4 small children who were sleeping). I expressed my concern to our property management so hopefully they don't ever contract these A-holes with no etiquette or people skills whatsoever.
Miguel C.The time had come for me to get a new roof so a couple months back on the advice of my contractors, I hired Champion Weatherproofing to do the job. I had previously met with a few roofers on my own without my contractor's knowledge and I never realized how hiring roofers isn't necessarily a simple task. I met with people whose prices were all over the place. I had one guy come out and all he did was stand at my driveway in front of my house and immediately gave me a price. Never went up to the roof to take measurements or inspect. This left a bad taste in my mouth as I felt like they wanted to scam me. After a few, I met with Champion Weatherproofing, specifically with Javier. Javier was extremely thorough. He went up on the roof, took measurements and asked me about my concerns and all the questions that I had of which I had many. He probably spent about an hour with me going through my questions and concerns and ensuring that I was at ease with the process. The next day I got the quote, so he was super-fast and efficient about it. The quote was not the cheapest, but it wasn't the highest that I had received either. The price was reasonable and totally fair, so I hired them. The one unknown was that they didn't really know if there was any wood rot or damage that needed to be replaced until the existing roof came off. I completely understood this, obviously. Of course, this would come at an additional cost and he was totally up front and honest with me about this, so I was totally comfortable with it. Within a week and a half and after pulling the permits which Javier did himself, the work started on my house and in a matter of a few days they were done. The crew that worked on my house were great. They were very efficient and thorough, and I really appreciated that they cleaned up at the end of each work day. They picked up all nails and scraps and really did a great job of this. Throughout the entire process Javier would come over every day to inspect and meet with me and ensure that I was satisfied and my concerns were met. He was really fantastic and overall just a nice guy. Once the job was completed, we did our final walk through and there was an issue with the wood on a portion of my eaves that I had previously addressed with him. This ended up being a miscommunication on my end, but Javier was so professional that he offered to replace the wood in question at no extra cost to me. He said they would pick up the tab on that and do what they had to do so that I was satisfied, again, at no additional cost to me. Mind you the job and roof had already been completed so this would have been a rather large deal to do this. At that moment, I knew I had hired the right people to do my roof. Here I am a couple months later and after probably the rainiest winter in California that I can remember my roof is phenomenal and not a single issue. I love my charcoal colored, cool roof with ohagin vents. My new roof looks so beautiful that several of my neighbors came by to praise how gorgeous it looks and questioning how much I paid as they too are interested. If I do say so myself, I'm now the envy of my block having the most beautiful roof. Since completion a couple months back, Javier has called me to check in on me and ensure that my roof was holding up fine considering all the rain we've had and to ask me if I was still satisfied and letting me know that if I have any future questions, concerns or issues that he will take care of me and make sure I'm happy. Javier is the man! A genuinely nice guy who really wanted me to be satisfied and happy with Champion Weatherproofing and the work they did. Thank you Javier and team for the phenomenal job you did on my house. You guys were fantastic, and I now have a brand new beautiful roof that I don't have to worry about for a long time. My best to you and your team always. Cheers to your continued success!
Dana D.Javier and his team are terrific!
I was referred to Javier by Steve Cedarquist from Flip or Flip. He had done work for me before he started with Tarek and Christina. He told me he sold his company to focus on design and other projects but he highly recommended Javier. Apparently Javier also worked on the show.
During the last bad rain, a leak I had before I closed on my new house came back with a vengeance! Supposedly it was repaired prior to closing, but clearly this was not the case. As the rain poured into my office through the ceiling and windows and through to the lower level kitchen and dining area, I was freaking out!
Javier came right over, covered the entire affected section with plastic until his team could repair. Thankfully we didn't have further rain but if we did, the house was protected.
Within 2 weeks from the first phone call, the job was completed. The Champion crew were all on time, friendly, they cleaned up and the price was fair.
If you have a need for this type of work, please call Javier!
John J.Thank you for the great work you just recently done at the residence on Columbia Ave in Riverside.
