If the chimney is fully within the plane of the roof, I use a two piece curb. If it is at the eave and extends past the roof line, I use a three sided curb. I use only welded aluminum curbs. I like to use LM Curbs in Longview, Texas but there are other companies that can and will make this type of curb. Attached is a picture of a three sided curb.
