No permit required where we live. The reason for changing the roof pitch is because it will double insulate the roof, and plus it looks 100% better than the 3, 12 that comes on them. Thanks Greg, I have considered that, just didnt want the post on the back of the house cause that is what we pull up ...

I have a 2003 Cavalier 24x44 for a lakehouse. I am wanting to change my roof pitch to 8, 12. It has 2x4 stud walls. I am wanting to use 2x10 for my rafter beam, and 2x6's for my rafters. I was planning on running lathe of coarse and tin for the top. Any harm in doing this? Thanks for any help..........
