Tips for Identifying Intentional (Advertent) Damage to Asphalt Shingles – The Pattern of Sufficiency – Part 4

Posted by in Roof, Shingles | May 06, 2013

We have been discussing three fundamental patterns that may be used to distinguish intentional manual damage  from naturally occurring hail or wind damage.  These fundamental patterns are:

  1. Natural Order vs. Unnatural (Artificial) Order
  2. Sufficiency vs. Insufficiency
  3. Compatibility vs. Incompatibility

In our last post we discussed the first fundamental distinction of intentional damage: there is usually an artificial Order to the damage that is not consistent with the more complex order produced by a natural weather event. In this post we will discuss the second fundamental distinction of intentional damage, Sufficiency vs. Insufficiency.

Insufficiency is defined as is the quality of not having enough. With regard to hail damage, insufficiency is the result of the inability of a person(s) to disperse the indentations and surface marks over the building components with the properly oriented directional exposure such that it matches the sufficiency pattern of  natural hail damage. Falling hail stones commonly make contact over the entire building from one predominant direction, thus resulting in a relatively uniform, directional, and dispersed pattern of damage.  With regard to wind damage, insufficiency is the result of the inability of a person(s) to disperse the lifting, creasing, fracturing, tearing, or dislodging over the roof components with the properly oriented directional exposure such that it matches the sufficiency pattern of  natural wind damage. The evaluation of the fundamental distinction of insufficiency may include consideration of all objects on the subject property and on adjacent properties.

The fundamental distinction of insufficiency reveals that man is incapable of producing the properly oriented and dispersed damages that a natural weather event produces. Thus, the man-made damage is found to be insufficient.

We would provide examples here, but we would rather not assist in the education of those who may be reading this information for nefarious purposes.  If you are a client of ours and are interested in examples, please email us at engineering@prugarinc.com and request the remainder of the blog article for Sufficiency vs. Insufficiency.

In the our next blog we plan to describe Compatibility vs. Incompatibility.
