ABSTRACT:
This invention provides a roof support upon which a firefighter or other user can stand. The support fits tightly against a sloped roof, thus the support is wedge shaped. At the upper portion of the support is a standing surface upon which the user will be supported. The roof support is locked into place on a sloped roof by inserting a T-bar attached to a chain into a hole in the roof. Once the T-bar is inserted, it is pulled up against the inner surface of the roof and locked into place by attaching a plug on the opposite end of the chain to a locking device on the roof support.
