Roof Assessment

This 2 Day course covers the fundamentals and techniques in establishing hail and wind damage to residential and commercial roofs.

Day 1 of the Roof Assessment course investigates hail formation, method of growth, and explanation of importance of wind in the hail equation. Students will gain insight in how hail size impacts velocity and impact, and why some hail does little damage and other hail is catastrophic.

Discussion will include ‘hail swath’ which explains the phenomenon of localized hail directly adjacent to no hail, slope and directional hail and how to adjust damage appropriately and how to recognize mechanical or manufactured hail based on damage patterns when investigating a loss.

This course teaches the ability to recognize legitimate hail damage on a variety of roofing products and includes explanation of appropriate repairs for each. In addition, students will be taught how to identify damage from wear and tear that is frequently and incorrectly attributed to hail.

All common residential roofing applications will be examined in addition to peripherals like fencing, decks, siding, patio covers, skylights, windows and gutters. At the conclusion of Day 1, students will be able to accurately indentify hail, prepare appropriate repair recommendations and understand the reasons behind their conclusions as it pertains to Residential Roofing Assessment.

Day 2 of the Roof Assessment course focuses on commercial roof assessment. It aids the student in applying standard commercial forms to wind and hail claims as well and outlining the five primary causes of commercial roof failure, Wind/Hail, Moisture Intrusion, Load/Collapse, Lack of Maintenance and Construction Defect.

Discussion will be given on wind effect such as pressure, turbulence, speed and the ‘venturi effect’. Moisture intrusion will investigate hydrostatic vs. hydrokinetic systems, flashing problems, ponding and general membrane degradation. Students will be introduced to modern roof inspection tools like infrared imaging, dynamic lift testing, nuclear moisture testing, capacitance testing and both low and high voltage electrical testing.

The course will include information on common maintenance issues such drain condition, roof settling and ponding, debris clogs as well as roof mounted systems. Construction defect is also a major cause of roof failure, along improper roof load design and adequate drainage.

At the conclusion of the course, the student will be able to knowledgably approach the loss investigation equipped to ask the right questions and understand the information that they are acquiring.

Following successful program completion, students are awarded a certificate reflecting their accomplishment
