"Called for a leak that no one else could find, 2 men were out the next day, inspected the roof and found a problem with flashing detail that was traveling over 30 ft before entering building. Clean, courteous, both men wore booties when they entered the building and again when they exited...Definitely recommend their service team."
"My company used OSR to install a warehouse roof and I worked closely with their admin and project manager for the project. They were really professional, helpful, and finished the job within budget and the timeline. They have a great follow up preventative maintenance plan with 2 annual roof inspections as well. It has been great to work with OSR and I was glad to hear my company will be doing more jobs with them in the future!"
"O’Hara’s Son Roofing has a great staff in the office and the field. I don’t know much about the roofing side of construction, but they made everything easy to understand and easy to get done. They took care of everything from ordering to equipment rentals to install to warranty. They offer a workmanship warranty, manufacturer’s warranty, and maintenance inspection plan to keep the quality of the roof intact. Nice working with them!"
