Abstract
A nail gun and depth control spacer assembly for ejecting nails into a substrate which contains two or more layers of roofing materials one of which is a compressible fibrous layer. The nails penetrate the substrate but are prevented by the depth control spacer from permanently compressing the compressible fibrous layer which springs back to is original thickness after completion of the nailing process. The depth control spacer, attached to the base of the nail gun, is of semi-oval configuration having a pressure sensitive layer and a solid layer, is provided with an oval cavity in its center portion through which the nails are ejected into the substrate.
