About Us

We specialize in residential re-roofing and have been building quality roofs for over 16 years. With over 24 years in the roofing industry, Grover Wonderlin has been the driving force behind his family run business. Believing that customers deserve the best quality work and knowledgeable service, Grover personally oversees every job from estimating to application of the new roof. In fact, Grover gives his cell phone number to every customer, so that he can be reached to handle any concerns or questions during the job.

With all his years of experience, Grover has an extensive knowledge of all kinds of roofing problems and solutions. Wonderlin Roofing Systems is fully insured with general liability, workers compensation, and bonded. While most companies carry worker’s compensation for their employees, less than 10% carry general liability insurance because of the expense. The danger in using those companies is that if anyone is injured during the roofing project & or property is damaged, the homeowner can be brought into a time consuming and expensive lawsuit.

Re-roofing or repairing your roof now can prevent costly water/dry rot damage in the future. Call Wonderlin Roofing Systems to schedule a free estimate today!
