What Happened Here?

Posted by in Roof, Shingles, Simple Forensic Methods, Winter Concerns | July 17, 2017

The shingles along the eave of roof exhibit broken and dislodged tabs and surface gouges (Figure 1).

What could have caused this?  Vigorous ice removal.

The damage is along an area that was reportedly covered with ice (see featured photograph).  Portions of the ice were reported to be manually removed in this area.  The shingle tabs exhibit gouges with relatively clean fracture surfaces (Figure 2).  The leaf guard exhibits fractures and punctures (Figure 3).

So, take it easy out there when removing ice or the cure may be worse than the illness.
