Commercial Roof Replacement In Buffalo, NY

If you own a commercial building, you know how important it is to have a solid roof. Your roof protects everything inside your building, and if it isn't working properly, that can mean problems with the rest of your building. If a repair can not bring your roof up to snuff, it may be time for a commercial roof replacement.

There are lots of reasons that people need to replace their roofs. The most common reason is that the material has worn out from the weather and needs to be replaced. Another common reason for needing to replace a roof is damage done to the existing roof by extreme weather like strong winds and rain. When it comes to roof replacement, you want to be sure that the roofers are competent in handling the job efficiently and safely. OConnor Contracting is your best bet for commercial roofing needs.

Types of Commercial Roof Replacement

We can replace any roof that you currently have on your business. The most common types of roofs that we replace are:

Bitumen: A bitumen roof is a flat roof made from coal tar or asphalt materials. These roofs provide excellent protection from UV rays and water, but they're prone to cracking, especially under heavy loads.

PVC: PVC roofs are made from polyvinyl chloride, making them very durable and lightweight. They can withstand harsh weather and physical damage, but they aren't ideal for areas with extreme temperatures.

TPO: Thermoplastic polyolefin (TPO) roofs have a similar lifespan as PVC roofs and are resistant to fire and UV rays. They are more affordable than PVC roofs and have fewer seams, making them less likely to leak. However, they're only available in white or light gray, so you'll need to paint it yourself if you want a different color.

EPDM: EPDM stands for ethylene propylene diene terpolymer. It's a single-ply synthetic rubber membrane, usually black but available in gray or white. Many businesses choose this type of roof because it is affordable, easy to install, and very good at resisting punctures.

Their estimate could not be beat.  There is no doubt that they are a hard working, professional group.  The house was protected, yard and debris cleaned up, and the installation was extremely well done.  I’ve done this work, I know what and how things should be done, and OConnor exceeded every single expectation.  There is no question I would recommend them to anyone I know looking to have work done on their own house. read less

Kris O’Connor was a total professional from start to finish. We had a few roofers give estimates but Kris stood out from the rest as being honest about what we were dealing with. He was willing to take the time with us and explain all of our options for the project. Once we agreed they moved quickly to get our job done. The crew showed up right on time and it was incredible how fast they worked. They were done in just a little over 2 days and the dumpster was gone and everything was cleaned up before we knew it. Each day Austin would give us updates on the project with pictures to show us all of the progress. He would take the time at the end of the day to let us know what they completed and what they would be doing the next day. I can’t give enough kudos to Kris, Austin and the rest of the team. I highly recommend O’Connor Contracting for their integrity, business ethics, professionalism, and truly great work. My roof looks incredible! Thank you O’Connor Contracting. read less

I called a couple other places and they told me it would be weeks before they could even come to look at my roof.  Austin came out the next day.

I had hired a bad contractor do a siding job last year and didn’t put shutters up. Austin’s team came in and fixed the siding that was uneven and not attached on a cape cod house and replaced some miss cuts and caulked around areas that should of been done to begin with. The biggest regret I made was not hiring him to do the job to begin with.  He also did some minor roofing work from auxiliary chimney and had redo it just before winter because the our contractor just decided to put the shingles on improperly and would had a major leak over the winter. I entrust him and his team I have coming back to minor job for gutter guard on my pavilion soon. Thank you O’Connor contracting for keeping it simple and upfront and just being honest with customers. 👍🏻💪 read less

Very professional, quick to respond and quality work. We had to do a full tear off of the roof from wind damage. Kris said two days but they were done by noon the second day. He even went above and beyond to help us work with our insurance to cover for damages and personally offered to come over and show and discuss with the inspector on the work to be done. Everything was cleaned up very well. Workers were very respectful of the property and did just an amazing job overall. Would one hundred percent recommend. read less

I called one place and they wanted $175 just to come out whether they repaired it or not PLUS any extra materials and an extra $75 per man per hour after an hour.  There would be three installers.  Well, if it only took an hour that would have been great.  However the woman with whom I spoke, could not give me any idea of time - even if I sent her a picture.  I very nicely told her I could not agree to such an open-ended situation.  The second company said they don't do three-story buildings so I asked if they could recommend someone.  He gave me O'Connor Contracting.  Kris O'Connor said it would be a $250 service call and they'd be out that afternoon.  Of course, I would have liked it to be less but was thrilled to get it done so quickly without wondering if there'd be added costs.  Three young men arrived and within an hour, it was up.  As I was paying for the job, he explained that a nail had fallen out so they secured the pipe into the house and I would not have another problem.  He was very gentlemanly.  I didn't meet the other two men but observed them working and they were enjoying themselves, laughing and talking...no bad language, loud music, smoking, drinking or raucous behavior.  I am thinking about having my upper porch rebuilt and will definitely call Kris for a quote.  The quality of work is paramount, but the conduct of the employees reflects the company's ethics. read less

Within days of calling them we had someone out for an estimate. Their estimate was the best quote we received. We decided to go with them and contacted them to proceed. That day they set the timeline for the roof replacement. Ultimately, they were able to do the roof even earlier than planned. They have a large crew who arrived early and set right to work. They worked together as a team and completed the roof tear off and replacement in the same day. The crew were friendly hardworking and professional. We highly recommend O'Connor Contracting.

Kris and Austin were wonderful to work with. Austin took the time to explain the entire process, worked with us and our insurance company through several delays, and was always patient, kind, and professional. He completely took away any stress and anxiety we had about the process. Their pricing is very reasonable, especially for the high quality of work and the overall experience. Our roofing crew was very friendly, worked quickly and thoroughly, and our property was cleaned up completely (no loose nails for kids or puppies to accidentally step on). We love our new roof and the peace of mind knowing that everything was done the right way. I would recommend O’Connor to everyone (and I will!). Thank you again! read less
