"The Orange Sky Roofing team was punctual, polite and professional. They communicated with me about every part of the job, followed through from the first step all the way to cleanup. I personally loved the transparency and the willingness to walk me through anything I needed more of an explanation of. Highly recommend!"

"Brian Dewald was our project manager for Red Diamond Roofing. What a relief this roofing company was to work with. After a horrible experience from our last one, Red Diamond Roofing came through for us after we had hail damage from a storm. They were fast and got the job done in one day. Now I don't have to worry about our roof leaking in our bedroom after a snowy day! I would definitely hire them again if needed. Thank you!"

"Salvador showed up right on time for the estimate walkthrough. Quoted my price and was able to schedule and complete my **remove and replace roof project** one week after my HOA approval was received. He stands by his work and did not take payment until the work was 100% complete and passed final city inspection. I have already recommended Excellence Roofing and Construction to others."

"I had a roofing problem which possibly would have worsened if it rained. I contacted Chris at 730 Exteriors on a Sunday and explained the urgency of the necessary speedy roof repair. He responded immediately sending one of his staff to evaluate the problem the next day after my call. And the work was completed the following day. Prompt service, great job and problem solved. I highly recommend this roofing pro."
