I am building an 8 x 20 porch onto my house which has a
4 in 12 slope roof.

I would like to use cedar wood shingle on the roof. I believe
this is the minimum slope for which cedar shingle is recommended.
I also am putting several skylights in, Velux models with the
step flashing used for ashphalt shingle.

Is this a good idea, or should I go to asphalt or metal? I like
the look of wood shingle much better. I plan to use ice & water
shield under whatever I use.

Also, I am doing things myself, and have experience with shingle
but not installing metal roofs. The problem is the flashing for
the skylights and metal roof could be too complicated for me.
But I am not sure if skylights and wood shingle is asking for
trouble on a 4 in 12 roof. Thanks,
