A flashing is an overlapping of roofing materials such that gravity will direct rain and melt water off of the roof. This is a universally accepted waterproofing method that does not depend on any sealant material. The concept is as ancient as the first, crude, thatched roof.<u></u><u></u></span></p><p class="ecxMsoNormal"><span style="font-family:"Arial","sans-serif";color:#1f497d;"><u></u> <u></u></span></p><p class="ecxMsoNormal"><span style="font-family:"Arial","sans-serif";color:#1f497d;">If you place a flat object on top of roofing without an uphill material lapping over the downhill object, you are not flashing. <u></u><u></u></span></p><p class="ecxMsoNormal"><span style="font-family:"Arial","sans-serif";color:#1f497d;"><u></u> <u></u></span></p><p class="ecxMsoNormal"><span style="font-family:"Arial","sans-serif";color:#1f497d;">What you have described is sealant-dependent weatherproofing.

Any sealant has a finite lifespan.

I just finished an install on a metal roof with hundreds of screw holes. We added a few more screw holes, and ours have 20 times the sealant surface area.
