To fasten the roof coverings to the roof, an underlayment comprised of fastening
material is applied to the roof deck in a similar fashion as commonly used
felt paper.
Once the foundation layer has been applied to the roofing deck, the roof
coverings
are attached to the foundation layer.
The alignment and installation of the roof coverings uses the traditional
shingle installation method, however the roof coverings are not penetrated by
nails, staples or other fasteners and are simply placed on the foundation
layer.
For example measuring and laying a chalk line. Placing the roof coverings in
alignment with the chalk line and then repeating this procedure while
overlapping each additional row.
The readily releasable fastener immediately
attaches the roof coverings to the roof and subsequent rows of roof
coverings. This
eliminates the nailing or stapling procedure and makes for decreased
install time, while providing the roof with a non-penetrated exterior
water barrier and an interlocking roofing system, providing for a more secure
form of attachment.
