I am proud to provide professional roofing services and home improvements to my customers. While most companies come and go, John Asch Contracting has been in existence since 1955 and is still expanding into new areas. I provide and execute all the many things you would expect and want a great company to do.
Most contractors offer a limited period of time on their workmanship and separately, forward a warranty from the manufacturer to the homeowner. Do not be fooled by a manufacturer's shingle warranty. Read the fine print, a warranty is not a guarantee.

The problem with this is that if the homeowner should call the roofer with a leak within the guaranteed period, the roofer can always say it's a material defect and it is not covered by the Roofers Labor only guarantee.What John Asch Contracting does differently is offer a 20 year guarantee on both the labor and the material.
Roofing projects can be a significant investment, especially when unexpected. Many homeowners like the ability to finance their roof work, so we offer convenient financing options to our customers. If you have any questions about financing any of your upcoming roofing projects, please give us a call at (732) 447-4516 to discuss how we can help you.
Over the years, John Asch Roofing has been very proud of how customers appreciate the work we do in New Jersey. Below is a small portion of the over 3,000 testimonials John Asch has received over the last 50+ years. Please take the time to read what John Asch customers have said about the kind of work we deliver time and time again.
Over the decades, John Asch Roofing has serviced and repaired hundreds of Slate Roof and Built in Gutters. Based on that experience we have developed the Slate Roof Annual Maintenance Program. This was developed to save customers thousands of dollars by monitoring the health of the slate roof and catch problems before they become more costly to repair.

In 2010 we had our old slate roof torn off and replaced with cedar shake. 11 years later the roof is as good as it was the day it was built. The process was one of the easiest construction jobs I have done. It was done on time and clean. Another contractor who did the same job for friend left the whole attic a mess of dirt and debris. Our attic never showed any signs work was done above.

Asch roofing installed my roof 6 years ago, this week I noticed a “bubble”. I called them Friday and they came right out and inspected what I was taking about. Thank goodness was it was only a nail, that didn’t attach to wood, because I have tongue and groove wood. Simple fix and covered 💯 under warranty. Thank you. So honest and trustworthy. I will always continue to recommend you.

After being discouraged by several astronomical estimates from "big" companies, we were amazed at John's honest pricing and 20 year "no leak" workmanship guarantee. John and his office staff were pleasant and easy to deal with. The day of the job was simply amazing! From tear down of 2-layers , through the install of the new roof and chimney flashing right up to the "cleaner" who came by after all workers left to do a thorough final clean up and check for nail on the entire property I couldn't of been happier. John must of called me four times during the job to personally check in and his son came

Straight and to the point without the fluff roof contracting. John Asch Contracting did a great job on my home. He also took the extra time to explain things I know nothing about. Any new knowledge he provided I was able to go and verify for myself. His pricing was very reasonable for our townhouse. His guys came in, did the work, found some problems, fixed them without going over my budget. The business & craft work in roofing with John’s company was worth every penny. I’m very happy with it.
