My home has a valley where a roof joint another roof and it is a V shape, I believe it is called a hog valley.
From the center of the valley there are no roof tiles for about 1 foot in both directions.
The problem is that this area holds standing water and I'm having trouble with some water leaking into the attic and studs in one particular spot. I had a roofer came and he had coated it with what looks like some tar and then a silver aluminum colored paint/coating.
It's been raining and that spot is wet again. I think the roof guy will warranty his work but I might have to find a way to fix it myself because I'm in CA and it doesn't rain very often. My roof is about 8 years old and it's got a layer of old roof below it already. It could be leaking down from some other spot but I would think it's likely the valley..
Any advice is appreciated.
