I have a combination roof, an A-frame on about 70% of the house and a flat roof on the other 30%. Shingles on the A-frame roof and asphalt on the flat deck.

I have been told, by my builder, that I require gutters all the way around my house. However, I have a roof that slopes in one direction, so it seems silly to put a gutter on the high side of the roof. It is a low slope metal roof. Any guideline or requirement help?
