Haag Metal Roofs Damage Assessment Field Guide

44.99

Like Haag’s previous releases, the Metal Roofs Damage Assessment Field Guide was created by Haag engineers to help industry professionals differentiate common metal roofing conditions.  The guide features over 50 pages of full-color, captioned photographs, as well as detailed introductory material and a robust glossary of metal roofing terms.  It’s durable pages are divided into four easy-to-reference sections:  Installation & Design Issues; Manufacturing & Weathering Issues; Hail & Wind Damage; and Mechanical Conditions.

Below are examples of the types of questions answered within the pages of the guide:

  1. What three basic rules are essential to consider when installing a metal roof?
  2. How can hail damage be differentiated from delamination, a mechanical condition?
  3. How can knowledge regarding uplift forces help you differentiate mechanically-caused issues from damage caused by wind?

Please note:  Haag Engineering Co. believes each roof must be inspected individually and assessed on its own merit. The purpose of the Metal Roofs Damage Assessment Field Guide is to provide a basic guide to damage assessment. Not all possible anomalies or causes of damage are represented or discussed in the book. Furthermore, recent court decisions have affected the way hail-caused dents in metal roofing may be categorized.  While the word “damage” is used in this book’s title (and though you will find a detailed explanation of “damage” within its pages), it is important to note that the word “damage” has different meanings and ramifications in the roofing and insurance industries.  While the term “cosmetic damage” may be defined in some insurance policies, we have not used it in the Metal Roofs field guide.  Beyond semantics, in our courses and publications we stress the importance of accurately reporting what natural and/or mechanical forces did (or did not do) to a roof and its surroundings.  Haag Engineering offers classes (such as Haag Certification) which provide additional information on this subject. When effects on metal roofs need further analysis, Haag's Research/Testing Division can offer assistance by analyzing panel samples for dents and possible corrosion.
