A device for use in securing a ladder to a roof for use in attaching roofing panels to the roof or for inspecting panels. The device includes a main body portion having a bottom floor having a plurality of corrugation openings formed therethrough, the corrugation openings sized and configured to straddle corrugations of roofing panels while allowing the bottom floor to lie substantially flat on the panel. A plurality of fastener openings are functionally associated with the bottom floor for use in selectively securing and detaching the main body portion to the roof using roofing fasteners. In embodiments attachment member chambers contain attachment members slidably disposed therein for use in attaching the device to a roof. Methods of using the devices for installing roofing panels and inspecting panel roofs are included.

A ladder seat assembly for assuming a seated position on a ladder includes a first bracket and a second bracket that are each positionable on a respective step of the ladder. A pole is coupled to and extends downwardly from the second bracket to engage the first bracket. A seat mount is positionable around the pole such that the seat mount is centrally positioned between the first bracket and the second bracket when each of the first bracket and the second bracket are positioned on the ladder. A seat unit is removably attachable to the seat mount wherein the seat unit is configured to have the user sit thereon while the user is on the ladder thereby enhancing comfort for the user.

A panel is disclosed which is suitable for installation to form a platform or part of a platform in a void of a building structure. The panel is operable to extend between a first support member and a second support member both of which extend across at least a portion of the void. The panel has: a deck component with: a first end and a second end opposite the first end; a pair of opposed, substantially straight sides each extending from the first end to the second end; and a substantially planar surface portion which extends: between the opposed sides at the first end, and from the first end at least part of the way, but not necessarily all the way, to the second end; and one or more first engaging formations at the first end of the deck component and operable to engage with the first support member to support the deck component relative to the first support member, and one or more second engaging formations at the second end of the deck component and operable to engage with the second support member to support the deck component relative to the second support member. At least one out of the first and second engaging formation(s) is/are configured to support the relevant end of the deck component relative to the relevant support member from approximately directly vertically beneath, and/or from approximately within vertical planes containing, each of the straight sides of the deck component.
