    Having to hire a slate roofer in the Allentown area (rather than relying on our old one in another…read morearea) turned out to be a re-education about the difficulty of finding a reputable and responsive roofer. In all, I made five phone calls to try to line up estimates on having slates replaced. Two never bothered to return the call. One called back 3-4 days later. Another called back 2 days later. (That guy, the Coplay, not Bensalem Romano, said he "doesn't do" estimates on slate replacements.) Just one called back that very day, and boy, did we luck out - J & M Roofing. We already knew the rough going price of slate replacement and J & M was right in the pocket. The boss, Greg, was a charming and down to earth guy and his son (he has two in the business with him) made a point of stopping by swiftly and taking pictures that were emailed to us to show exactly what needed replacing. Greg has been in the business a long time and knows how to ration his time. Quicker jobs like ours get reserved for days of iffy weather and weekends, and indeed, the following weekend he and one son and one helper showed up and got the job done in short order. The job was done just recently so I can't tell you about durability. I can tell you that we were happy with the speed of response, and that all the workers were personable and cleaned up afterwards decently. Throughout the process, Greg was a good and consistent communicator too. If you're looking for an experienced roofer - and one who knows slate - definitely include J & M Roofing in your considerations.

    Had them re-do a leaky roof entirely about 1.5 years ago. Greg came out and walked me through the…read moreproject, listened to my concerns, and built my quotes accordingly. He didn't overcomplicate the project or load me up with roofing jargon like other contractors did. Their quote came in customized to our project and was built to have no large "extra material " surprises when the project closed. They were always communicative and friendly about the project. When they encountered a situation that was abnormal, they walked me through the issue and offered resolutions that would've cost them money. They seem to be stand-up craftsmen who want to do a good job at all costs and don't treat their customers like just another number. If you are going to invite anyone to do work on their home especially on your roof, they are the type to get.
