Customer Reviews

"I interviewed many contractors before selecting GJ Goss Contracting to install roofs on both of my houses. The reason I selected them was because of their kindness, patience, and responsiveness to my requests. They were completely professional, double checked their work, and cleaned up their messes completely. They may be more expensive then other contractors out there, but I chose them because they really seemed to care if I was satisfied. I highly recommend Goss Contracting."
"From the moment I reached out to the company through the final payment they were responsive, professional, helpful, and thorough. They even came back to seal a leak the same day as the estimate which was not part of the work but they wanted to ensure no further damage occurred. The roof was removed and installed in less than a day and it looks great. I highly recommend this company"
"It was a great experience from the beginning to the end. Personable, did an excellent job and on time. They cleaned up well!"

WHEN SOMEONE CAOME TO LOOK AT THE LEAK WE WERE TOLD THAT WAS NOT SO AND HE DID NOT BELIEVE WE WERE TOLD THAT IT WAS GOOD FOR 20YEARS. IT TOOK TWO SEPRATE INSISTS BY THEIR BEST MECHANICS BEFORE THE LEAK WAS FIXED. NOW AFTER 8 MONTHS THEY HAVE FINALLY SCHEDUALED SOMEONE TO REPAIR THE INTERIOR DAMAGE CAUSED BY THE WATER LEAK. IT TOOK NUMEROUS CALLS TO THE COMPANY TO GET THEM TO COME BACK TO FINISH REPAIR WORK. THIS IS JUST POOR TREATMENT OF US AS THE CUSTOMER.
