Siding Joint Flashing

Where can I buy joint flashing for use when 2 pieces of house siding butt together?

Thanks.

If you are talking 'Z' flashing for where there is a vertical stack of sheet siding (like on a gable end), the same place you got the siding should have it. If not, any builders supply will- a very routine item. Make sure to not deform the 'Z' shape to make a pocket of water that the upper board sits in- best to hold it slightly off the metal 'shelf' with shims as you nail it up. There should be no need for flashing on the vertical joints, since there should be a lap joint on a factory edge. If you are piecing in an area, either fake the lap edge, or nail the joint tightly and caulk.

If this is horizontal plank siding, there should be no need for flashing- use a mitered lap joint, or butt tightly and caulk. The Tyvek or tarpaper behind provides the moisture seal, the siding is basically porous to moisture due to the horizontal lap joints. (Need to make sure the house wrap and/or metal stock flashing at bottom of wall extend below rim joist/sill plate, and provides a drip edge, or that wood will get wet.)

Standard cautions apply- always seal any cut edges before you put the siding up. Especially true for sheet siding- that lower edge loves to suck water, double-especially at foundation level. As you make each joint, look at it like a drop of water would- make the outside of the wall away from the house, the easiest path to follow. (I've replaced plenty of fascia boards and fly rafters where this principle was NOT followed...)
