A roof scaffolding system includes a curved roof hook attached to a linear, metal membrane strip unit having connector rivets and nail holes. The metal strip includes double slot keyholes and attachment apertures that engage corresponding rivets on the roof hook. The opposite end of the metal strip includes connector rivets engaging double slot keyholes of an identical metal strip, extending opposite the roof hook. The nail holes allow attachment of wood spacers beneath the metal strips. Multiple strips are joined extending from the peak to the roof edge. A coupler connector covers the connection between joined metal strips preventing disconnection. Roof jacks include both nail slots and keyholes for attachment to the metal strips, as well as safety hooks for attachment of a lanyard from the scaffolding to workers. The roof jacks hold a plank that spans adjacent metal strips, the plank providing a place to stand.

New sod mats are described. The sod mats are reinforced with a coherent sheet of stable fibers and degradable matrix material. The sod reinforcements are easy to manufacture and handle. The sod mats have good of handling characteristics, good sod mat propagation characteristics, good 'shelf life' stability, and are more easily dispersed into the soil by rototilling or other means when the mats are no longer useful as sods. Sod mats of grasses, ornamental plants, and nutritional plants are disclosed. The method of propagation is disclosed.
