Customer Reviews

"O'Hara's Son Roofing has been nothing but friendly, incredibly responsive, and professional. They reply quickly anytime we have questions for our business or need anything and are super knowledgeable and helpful. Highly recommend."
"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!"
