I have a fairly new metal roof (2 years old). The contractor is no longer
available. As my plumber had predicted, wind blows water under the edge of
the roof. Roof edge is guttered full length and is 60 feet long. Said edge
hangs into the gutter approximately 1 to 1-1/2 inches. Rain water blows up
into the raised 'bumps' of the roofing panels.

My idea of a fix would be to stuff a tiny amount of something (maybe wadded
insulation) up into the bump to use as a stop. Then fill the 1 or 2 inch
remaining cavity with foam (Great Stuff?). The foam would go only as far as
I shoved the 'stop'.

Anybody have any better ideas please submit and criticize mine!!!

Thanks,

Ivan Vegvary

The material is commonly called bird stop in the trade and closure
strip as a more technical term and is quite standard in the metal
building business. Here is an example for R panel:

If you do not have R panel, you will need to find a supplier of
the type of panel you have to buy the appropriate shape. MBCI
carries quite a few:

Thanks everybody. The metal supplier is within a few miles of me. I never
considered that they have a metal trim piece (bird stop) just for this
purpose. Thanks again.

It is my understanding that roofs of this type, like tile roofs, need
drainage and ventilation at the bottom and not a seal. Even if there are no
leaks, condensation will cause dampness under the metal and it needs to be
able to dry out.
