Schranz Roofing In the News


“It is a pleasure to work with a company such as Schranz Roofing. Whenever I have any roofing or related needs at any of my Commercial properties, I use Schranz Roofing.

You take pride in the quality of your products and workmanship and are willing to stand behind them. I greatly appreciate the prompt and thorough response you provided to my requests. I will continue to recommend Schranz Roofing to my real estate colleagues.” Lisa Fare

“Schranz Roofing may say they are in the Roofing business, but they truly are in the customer service industry. They take care of their clients and make sure all the work they do is of the best quality. During a half million dollar roof replacement that I expected to be a nightmare, due to the location and age of the building, Schranz not only did the work on the roof without issue but also facilitated the other vendors necessary to build new stairs and fix some masonry work on the roof.

After enlisting the help of Schranz to complete the project, the owners were over the moon with how well everything went!! From the quality of work done to the ease of managing everything.

Not only is Schranz great at roof replacement, they also are experts at maintaining and performing maintenance on existing roofs.

The other site I managed spent significant funds to maintain the roofs on multiple buildings. When Schranz was brought in to inspect the roofs and to do minor repairs, they provided a detailed and well-organized plan to help customers understand the inspections and what steps should be taken to extend the life of the roof. 

The team at Schranz is happy to help solve problems, even if it means climbing on a roof with a property manager in subzero February temperatures to find that pesky leak that is being reported. The customer service does not stop with the account manager or sales representative and continues with the workers on-site. Every worker and crew that show up to do repairs is on time, communicates professionally, and is respectful.” Tom Witkauskis
