"1. punctual on estimate appointment 2. three estimates were solicited all were equivalent service for product two allowed for Owens Corning or GAF and were certified as was On Top 3. The date proposed was mid October but the actual work was much sooner (low slope roof) and completed in several hours The roof has now gone through several seasons without issue. I recommended them to a friend of my wife"

"We just had our roof replaced by Global Roofing. It was amazing to work with Andrea and Freddy. We couldn’t have been happier with the whole experience! We got several quotes for our roofing job, changed our mind about the material along the way (went from metal to asphalt), and Andrea and Freddy were great throughout the process. Global Roofing had the best recommendations (one of the reasons we chose them), and after working with them we know why! Communication was amazing, if there were any delays due to ordering supplies like the skylights we were immediately informed, and the final scheduling for the project was also easy. I was at work all day while they were actually doing the roof, and other than the new beautiful roof on my house I was not able to tell that any contractors were at my house all!!! They covered the house in tarps while taking the old shingles off, and the entire surrounding area of my house was spotless when they left! And the Final product looks great! A truly great company, and I am looking forward to hire them for future projects!"

"I couldn’t be more satisfied with the work done by Robert Evans Jr. Contracting. The price was fair, the work was exceptional. The crew was obviously very experienced and was very meticulous about their work. The crew chief kept me informed of their progress, any issues they found and how they were addressed. They did an excellent job cleaning up the entire site before leaving. Within a couple of hours of my initial contact I had a date for a visit to review the project and provide an estimate. I received the estimate later that day by email and was pleasantly surprised by the reasonable quote and timing was only two weeks and that it would be a two day job. The crew arrived exactly two weeks later and at the end of the first day all of the original roof was stripped and 80% of the installation of the underlayment, shingles and trim was complete. They finished on day two, and after they finished the entire crew did a site walk around looking for anything they had missed. I would definitely recommend Robert Evans Jr. Contracting for all your roofing needs."
