Haag Certified Like you, we and our employees live and shop in the areas that we serve – Cincinnati, Dayton and Columbus, Ohio, and the Chicagoland, Illinois area. And like you, when we need to hire a local professional, we look for ways to tell whether the person or company is reputable, credible and does quality work. We ask around, we go to their website, we search reviews on the Internet and we check with the Better Business Bureau. But when it comes to roofing, we wanted to take this guesswork out of such an important decision, especially when you consider how essential a roof is to your home and the investment required. That’s why our company has employees who became Haag Certified Roofing Inspectors.

What is Haag?

Haag is actually the last name of the founder of Haag Engineering, a multi-faceted firm specializing in residential and commercial forensic engineering. Walter G. Haag, a civil engineer, established the company way back in 1924 to examine why structures, materials, components and products fail or do not function as designed. In its research and testing laboratory, Haag engineers assess roof damage, whether it’s from storm damage, improper installation, manufacturing defects, or mechanical-related causes.

This expertise is the foundation of the Haag Certified Roof Inspection (HCI-R) program. The training and testing program educates roof inspectors, adjusters, roofers and other professionals working in the roofing industry on how to apply forensic engineering principles to roofing systems. Those who successfully complete the program are certified as an authority in roof inspections. As such, whenever you see the Haag Certified Inspector emblem, you know that you are doing business with an expert in the roofing business.

Haag’s Rigorous Training

Before anyone at the Roofing Annex could become a Haag certified roof inspector, they first had to be the primary roof inspector on at least 100 residential roof inspections to meet Haag’s experience requirements. Once approved, they had to undergo a rigorous program that consisted of intensive training on all aspects of roofing systems and their applications, in-depth reviews of case studies that depict real-world inspection situations, and comprehensive testing that demonstrated their understanding of the course materials.

Here are just some of the topics covered during our participation in the Haag residential certified roof inspector program:

  • Roof inspection techniques
  • Inspection safety techniques
  • Roof area calculations
  • How to assess damage to all types of residential roofs using scientifically-based techniques
  • Manufacturing, installation, maintenance, mechanical damage, storm damage and weathering factors of all residential roof types
  • How hail and wind impact roofing
  • Roof repair versus roof replacement analysis
