GBR Corporation is the premier roofing contractor in south central Wisconsin.  For over 30 years we have worked with general contractors, building owners and property managers to install and maintain commercial and industrial roofing systems.  As an elite Firestone Master Contractor, we pride ourselves on expert craftsmanship, efficient application, punctual service, integrity and a commitment to safety.  These client centered values have allowed us to grow to offer customers a full and comprehensive menu of services to meet every roofing need.

We install, maintain and repair all commercial and industrial low-slope roofs including:
  •  TPO
  •  Modified Bitumen
  •  Built Up Roofing
  •  EPDM
  •  PVC
  •  Green Roofing

We also assist our customers with extending the life of their roofs by ensuring they are regularly cleaned and inspected.  Preventative maintenance is essential to lowering roofing costs.  Failure to maintain a roof can lead to voided warranties and thousands of dollars in preventable repair costs per year.  

  1. New Construction
    GBR Corporation has been installing roofing systems and providing new construction specialty services for over 30 years. We work with general contractors, architects and property owners to identify the best roof application for your building. We also offer consulting to ensure your roof system functions as designed.
  2. Roof Replacement
    Need a new roof or not sure if you need a new roof? We work with building owners, property managers and general contractors to evaluate the condition of your roof. If replacement is necessary, we work with you to identify and install the most energy-efficient roofing system that best fits the needs of your building and budget.
  3. Preventative Maintenance
    The roof is a very important component of your building and it is susceptible to many types of wear and tear from the elements, temperature fluctuations, debris and the trades. Roofs are also costly to replace. We believe that every roof should be properly and proactively maintained to ensure that owners get the most value and longevity out of their current roofing system.
