"It was a small repair and this Company contacted me quickly, even before the appointment time I chose, and came out of his way to do this work, did more than was necessary, didn't charge me more than the initial estimate, and gave me excellent advice. When I am ready to replace the roof, Guardian is the one I will call. Thanks for referring them to me!"

"Gene and his team did a wonderful replacing one of my roofs, replacing my front gutter, repairing my front columns and fascia, sanding and painting the wood timbres I have had for many years that house my front garden and solar ornaments.. They also did a wonderful job painting my alley walkway, doing a partial replacement of my porch floor and wonderfully tarping the floor as well. Taking over and repairing my family home that I inherited from my mother has and continues to be a labor of love, and Gene and his team are one of the reasons why. They are easy to talk to and Gene is flexible and reasonable with estimates, budgeting, and warranty. I highly recommend him."

"We had a 5" gutter and the guards were not affected because we have a large Maple tree.  The guy that came to do the work said that we needed a larger gutter due to the roof overhang.  He sold us a 6" heavier gauge metal.  In talking with other people, two other providers said that the gutters are larger and heavier than what we needed.  I feel like we didn't need these upgraded gutters that he sold to us.

He cleaned up very well.  We just didn't feel like this was a good cost for what we received."

"First and foremost, Premier were the only roofing company in the area to actually call me back when I had a leak. We decided to go ahead an replace the entire roof then and there. Their crew were absolutely amazing and efficient. They were timely and polite. We had some issues with communication over materials but Premier went out of their way to resolve them. One particular instance had the owner himself over to install a skylight blind. I would definitely recommend them."

"I have nothing but great things to say about adelphia roofing systems. The office manager was great and I do apologize her name is slipping my mind but I believe its nici. Any we set up appointment for joe to come out and eveulate my roofs we have two kinds of roofs shingles and flat roofs. He was excellent so so very thorough and knowlegable about both kinds of roofs I knew within a few minutes he was our guy. From there he drew up contracts where I signed and two days later was on adelphias schedule. The guys showed up secured my entire property with tarps and caution tape tore off all roofs down to wood they had to install few sheets of plwood six I after they completes the roofs the clean up was top notch. I highly recommend adelphia roofing systems..."
