Company Profile

Grover Wonderlin has been the driving force behind his family run business since 1992. He has specialized in residential and commercial re-roofing. Grover’s Son in law Ryan Piekarczyk has been part of the backbone of the company. He started with Wonderlin Roofing in 2003 as a job foreman and is now co-owner with Grover. Believing that customers deserve the best quality work and knowledgeable service, Grover and Ryan personally oversee each and every job, from estimating to application of the new roof. Although this limits the number of roofs they can complete at one time, they prefer to give their customers this personal service: “Quality instead of quantity”. The customer ends up with a better roof and far less headaches. In fact, Grover and Ryan give their cell phone numbers to every customer, so that they can be reached at any time, between 9am-5pm, to handle any concerns or questions during the job.
