The course reviews proper methods for completing research and analysis on roofs before and after inspection.

DESIGNED FOR: This advanced level course is designed for experience residential and commercial property damage estimator and appraisers.


EFI Global Professional Engineers (PEs) and Registered Roof Consultants (RRCs) provide the technical content and instruction for the 4-day course with detailed information on steep and low slope roofs, including construction, coverings, storm damage assessment, damage estimating, product identification and repair methods. For hands-on experience, this course also includes simulated hail mockups to illustrate impact dynamics on different roofing systems.

Following the course, participants must successfully pass a 3 hour, 50 question multiple-choice exam to become EVS/R® certified.

You will learn detailed information on the following:

Steep Slope roofing systems including:

  • Shingles
  • Clay Tile
  • Wood Shake
  • Slate
  • Architectural Metal Panel/Metal shingle

Low Slope roofing systems:

  • Single Ply PVC, TPO, and EPDM
  • Built Up roofs including Modified Bitumen, Coal Tar Pitch or Asphalt BUR, Ceramic
    Granule surface, Flood Coat and gravel, Aluminum Oxide Emulsion

Roof design considerations, including:

  • wind pressures
  • penetration and edge treatment
  • insulation
  • emissivity
  • drainage and environmental damage to roofing systems

Building code and legal considerations, industry standards and manufacturer/association
recommendations. Industry standards based on:

  • International Building Code (Commercial)
  • International Residential Code (One and Tow Family)
  • International Energy Conservation Code
  • National Roof Contractors Association
  • The Asphalt Roofing Manufacturers Association
  • National Tile Roofing Manufacturers Association
  • Western States Roofing Contractors Association
  • Tile Roofing Institute

Mechanism of moisture penetration of the building envelope including rain, wind driven, advection and

Mechanics of wind, how it is measured and if impact on roofing systems.

Storm damage assessment is reviewed in detail so that the student will understand the basic mechanics of storm related damage and be able to differentiate storm damage from mechanical, manufactured and construction related defects. It includes explanation of functional damage, modes of failure with specific examples of each, how hail is formed and the velocity and energy associated with various types and sizes of hail. The course instructs how hail damage causes cosmetic distress and includes corroborating evidence with specific examples provided for each roofing material/system. Students learn how to complete a qualitative evaluation to confirm and delineate hail damage and how to determine if the amount of damage warrants repair or replacement.

The course provides detailed information and examples of qualitative water intrusion evaluations including the following tests to determine if a prescribed condition will leak and where.

  • spray rack testing
  • water penetration testing
  • negative pressure uplift testing
  • capacitance testing
  • nuclear moisture testing
  • low voltage electrical testing
  • high voltage electrical testing
  • infrared thermography

The course provides specific information on how infrared thermography is used during inspections.
Cases from actual engineering studies are used to show various conditions than can be identified with
this method. Information on destructive and laboratory testing including core sampling process is also


The EVS/R™ exam has 50 multiple-choice questions that involve the following topics:  codes and standards, roofing materials and properties, assemblies, and damage evaluation and estimating.  Some problems may involve mathematical computations that require familiarity with basic algebra. 

The exam is 3 hours in duration.

The exam fee is included in the course cost.

Participants must successfully pass the exam to become EVS/R™ certified.


The total cost for the program is $1595.
