ABSTRACT:
A roofing system has a sheet surface which may include standing ridges or batten ridges, and the sheet surface has a predetermined arrangement of three dimensional features in addition to the standing ridges or the batten ridges. A snow stop may be installed in conjunction therewith, and may have lower protrusions which may be generally complimentary thereto and/or a snow wedge so as to further help keep it from being disengaged by typical shear and/or peel forces after installation. Thus, for example, as with aluminum or steel standing seamed roofs, added fence type snow guards with their brackets and so forth can be avoided, and/or individual snow stops can be installed so as to have greatly increased holding power to the roofing surface, even in notable cases when applied by underskilled workers.
