I have water backing up behind my eave under the shingles and eventually it's getting behind the outer wall and leaking through the drywall into an interior room around a window frame.
I know I need to fix it properly and I will, eventually, but I'm headed south for 2 months right after Christmas, so there's no time for a new roof job now.
Would it work at all, as a temp fix, to prevent major water damage while we're gone, to just drape a tarp over the leading edge of the roof, in front of the eaves and drip edge, and fasten it down tightly with some of that black sticky goop while we're away?
it would be better if you covered the whole roof with a tarp, I wouldn't try gooping it down, yes you need a big tarp but otherwise the water is going to get under it any way, wouldn't cleaning the gutters help any?
take a piece of coilstock with a break in it slide it under first or second course and bent over outside of gutter. Fasten to gutter not under shingles, this may allow snow/ice to slide off versus hanging in gutter causing ice dam
