Where may I purchase blue tarp?


Any sort of tarp would do.


The roof pitch may well be too shallow. I don't know what the pitch is.
There are no gutters on the second story roof.


Then there's your most likely culprit. Letting the water sheet off that
roof and down onto the other is a bad idea. Not just from the water but
from the wear the flow would cause.


I agree with you that caulking is not the true solution.


A section of gutter and some downspout can be bought from your typical home
center for not much money. They're easy enough to install, you just need a
ladder that'll reach.

I agree with you and will do this right after Christmas.


I don't own
the house so I'm just trying to do some stopgap repairs until I can move.


Well then a BIG UGLY TARP might be just the thing to 'encourage' the owner
to wake up to the damage that's being done to the house.
LOL, you just might have the ticket here. Thanks.
