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.

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. We did run a 1" conduit through the roof, and since it was an actual penetration, we used a very expensive flexible boot flashing.<br>Personally, I think we need about a 3"x3" or 4" x 4" L foot with a double stick butyl tape on the bottom, and all will be well.<br>I realize that the OP was referring to asphalt, but I will flash other roof types that don't do well with L feet ( like shake).<br><br><o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
