Overview
About Us
O’Leary Construction is a second-generation family business of roofers and general contractors for home construction. From the time I was fourteen, I have been in the construction industry working to ensure that our homes are professional, efficient, and economical. I take pride in running the business today, with enhanced supplier relationships and quality craftmanship that reflects our strong family tradition. I routinely recommend green construction for my customers, embracing the hope that we can all contribute to making this world better for our families. Roofers in Monroe County, PA and Warren County, NJ When customers start with O’Leary Construction, they often begin by looking for roofers to install new GAF asphalt shingles or metal roofs. Over time, our satisfied customers turn to O’Leary Construction for much more! Whether you are looking for replacement windows or new siding, roofing or insulation, renovation of basement, bath or kitchen, or restoration of an historic dwelling, I have the experience and the team of licensed professionals to realize your vision within your budget. My team covers Pennsylvania and New Jersey, so if you have a residential or small commercial construction need, please call me at 570-994-6004. And, we’re “on call” 24/7 for insurance agents and homeowners in case of emergency.

Customer Reviews

"My experience was top notch. Professional, on time, clean, efficient in a timely fashion. I’d highly recommend them to anyone looking for roof work. Upfront and honest with pricing as well as time for job to be completed. Gave constant updates each week leading up to the job and were highly communicative during the process. Everyone was nice, on the phone and in person. We felt we were being treated as family. I believe there is no superior roofing company available to meet your needs. Call them."
"Since I came to the market for a new Roof I have contacted 3 different companies to receive quotes. Not naming the others, my third contact was O'Leary Roofing. As expected they sent out a Roof consultant to for a visual of the roof and a quote. So on the appointment day at the exact scheduled time Mr. David Stein showed up at my door. After the introduction and a brief discussion of what I needed Mr Stein did a very thorough inspection of the roof, on top and inside the attic. Presented all the findings with all do and don'ts. Did a great presentation of the work to be performed and finally presented the Quote. Price was not very far off from the competitors but the Warranty offered was not even mentioned by others. Decided to sign a contract for the roof replacement. The work that O'Leary personnel did was nothing shy of Excellent! They arrived on time all were very polite through out the entire time while on the premises. They replaced the roof in one single day. When they left the property was left clean and free of any debris. They had they men walk around with a wheel magnet to make sure that no nails were left behind. Great Work from the entire team. Recommend their services to anyone in need of a roof."
"Real Customers here. My wife and I appreciate it everything this company has done for us. Our home roof was poorly built by immatures. An O'leary Roofing agent did an inspection and directly told us what was wrong and what needed to be fixed. They provided us with photos. They also assisted us with Financing which helped us a lot. Big shout out to the Team, Michael, Christine, Mike, Meghan, Mike, Dara and Corbin. I highly recommend this company. Check out some pics."
