Roof Leak

So here is the story in pictures. The roof over the covered end of the deck leaked down through the interior wall. Water FLOWED down the interior of the wall into the crawl space, along the outside of the crawl space wall, into the new shop, and during particularly heavy rains, down the sliding door of the bedroom. We believe this was caused by the valley metal between adjacent roofs being installed BENEATH the porch roof metal. Water coursing down the valley was thus dumped UNDER the porch roof.

The "fix" was to cut through the valley metal and slide in a large piece of flashing to allow the valley water to flow onto the TOP of the porch roof and away from the house beneath. The first three pictures show this attempted retro fit of the valley.

Because this area of the roof faces the west and enjoys the full force of western winds and rains, we also added blocking material under the the ridges and under the flashing. This blocking can be seen in pictures 4 and 5. In picture 5 you can clearly see the blocking under the flashing and in the background the blocking under the roof metal that blocks water from going up under the ridges.

The last picture is a panoramic of the valley view from the roof.
