Flashing / moisture barrier details

Anyone have a good site for flashing / moisture barrier details…

Did an investigative inspection where the double band joist is completely deteriorate due to improper / lack of flashing between concrete of porch (negative slope) and band joist. under front door.



What is on the house for cladding?

vinyl siding…over celotex

Here is the mess…

So it all starts at the sill of the upper window with water intrusion.

No moisture barrier at all?

Actually both failed…however the main failure was between the porch and band joist.

Was there a moisture barrier?

no moisture barrier at all…its a Ryland Home…(that says enough)…

So the carpenters nor the flat work CON-tractors felt the need for flashing against the wall.

And the city codes officials do not inspect for flashing at that place.

home was built in 94’ however they (code officials) should have caught it but than again it has been my experience that the tract builders get away with allot…code officials rely too much on site supervisors to take care of stuff and of course they are in such a hurry to put out their product that its common that such things get dropped.

Brick layers understand the need for rim flashing!
