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

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.

I'm sitting here wondering how you know there is water blowing under
the eave. You should have felt under the metal, precisely for the
reason Don Young is bringing up--condensation could form under the
steel. So if you have felt, how would you know water is blowing up
there? If you don't, you could have more trouble than just the open
gaps at the eave.

Thanks for you concern. The metal roof has 1" insulation under the panels.
This metal/insulation sandwich is screwed down to 2x6 rafters 16 inches on
center. About 4-5 feet below is the ceiling (topped with 3/4" plywood) of
my finished space (this is a shop). The top of this ceiling is what I call
my mezzanine. I walk on this mezzanine and use it for storage. The
mezzanine had a large (about 3ft x 7 ft) puddle on it near the edge of the
roof. I tore back the thin insulation and only the outer 6-8 inches was wet
for a length of about 4 feet. I'm sure that it is rain being blown in from
the outside. BTW, have not fixed it yet, had lots of rainy days but no
wind. Everything is pretty dry now.

Your concern about ventilation. As I explained the whole roof metal is
underlain by this thin blanket (Mylar or vinyl on the underside) of
insulation. Said blanket is fully exposed to my shop. If you think I still
need ventilation I would rather put up the 'bird stop' and simply slit the
insulation a few feet further into the building.

What do you think?

Thanks again,

Ivan Vegvary
