I have a walkout basement and a stone veneer chimney that starts at the first floor(not ground level) and extends above the roof line. I discovered water was leaking into the framing in the basement and assume the stone veneer was waterproofed improperly. I never liked the fieldstone anyway so I was planning to tear it off and use a drystack next time. Since I will probably have to replace osb sheathing, would zip system be more appropriate for this application and would it pay to use ice and water shield on the entire chimney instead of felt paper?
