Maintenance Programs

Whether our clients have a current issue or want a proactive plan, R. B. Hash & Associates, Inc. offers comprehensive maintenance programs based upon each individual project’s needs. While each structure and client’s needs are different, R. B. Hash & Associates, Inc. customizes a maintenance program that will save our clients’ money by minimizing unexpected repairs.

If a roof system is not properly maintained with semiannual inspections, its life expectancy is at risk. Often, our clients purchase a manufacturer’s warranty upon new roof installation, however, regular maintenance is required to keep the warranty intact. At R. B. Hash & Associates, Inc. our goal is to extend the life expectancy of our client’s roof system with a value driven, proactive approach. If a potential issue is caught early, the repair can be made in the most efficient and cost-effective way possible.

Sample Maintenance Program:

  • Semiannual Visual Inspections
  • Removal of Debris
  • Minor Repairs
  • Comprehensive Report
