Located just inside the outer most border is another border of equal width that runs inside the outermost border all the way around the shield. In the top left corner, where the tear is located, the inner most border curves around the right side of the tear and connects to the outtermost border at the top left point of the shield. In the middle of the shield is a shamrock which is rotated 45 degrees left from vertical. Immediately to the right of the shield are the words "Roof Rain". Immediately to the right of the shield and below the words "Roof Rain", are the words "Algae Prevention Solution".
