Abstract
A tool for marking the location of a bonding plate concealed beneath a roof membrane. The tool has a magnetic attraction to the bonding plate and causes a marking assembly to vertically lower toward the roof membrane and rotate on an axle. Rotation of the marking assembly and vertical lowering causes the marking implement to come into contact with the roof membrane at a location corresponding to the location of the bonding plate beneath the roof membrane. A brake restricts the rotation of the marking assembly on the axle by coming into contact with an inner edge of a chassis. Contact between the marking implement and the roof membrane and the restriction of rotation of the marking assembly by the brake cause the marking implement to create a visible mark at a position corresponding to the location of the bonding plate beneath the roof membrane.
