What is a Hog Valley

What is a Hog valley?

Here is a photo I took just as my crew finished up of a cedar shake roof with what I call a hog valley. It was getting dark and just starting to rain but is an example of two roofs that parallel each other and join together at some point normally near the eaves of each section of roofing. This creates a need for a different type of roofing material to be used to make a waterproof roof. It can be roofed with any type of low sloped materials.

We chose here, to use a Modified Bitumen torch applied product that is a commercial low slope roofing product that works perfectly for small residential jobs like this. It is applied using a torch to attach the roll of roofing to a nailable base. This two-ply roofing system has the top ply being a granulated surface for protection and this double layer torched down roof should last 20 + years. This fits the budget of this roofing project done in 2001, and with no seams or metal terminations to fail, it should last as long as the heavy shake roof.

In little time, this critical area of a roof, prone to failures, can be incorporated into most roofing types and perform very well, directing the water out both ends. Some times this area will puddle if not sloped correctly, giving the look of a sow's belly or Hog Valley.
