A footer square apparatus may be used to measuring a building foundation and may include a footer square body, a first guide line, a second guide line, a third guide line, a corner marking, and at least one angle marking. The first guide line and second guide line may be perpendicular, and the third guide line may form a 45 angle with the first guide line and second guide line. The at least one angle marking may identify an angle as measured between a line from the corner marking to the angle marking and at least one of the first guide line, the second guide line, and the third guide line.

A tool for facilitating the cutting of shingles having a base plate and a tubular member. The tubular member comprises a slot on the horizontal surface of the tubular member that extends the entire length of the tubular member and that is offset from the center of the tubular member. The base plate comprises a semicircular cutout with a terminal point that coincides with the center point on the first side edge of the tubular member. The first side of the tubular member is aligned with the longitudinal axis of the base plate so that the tubular member is off-center on the base plate.
