extending chiminy stack
I am new to this board so please forgive me if this has been asked before. We are doing a remodel to our home. The roof on the back of our roof is flat (where the fireplace is located)Since this can create problems with water we have decided to pitch the roof to match the rest of the house. The city says if we do this our stack will not be high enough so we need to extend it. The chiminey is brick now but we plan to cover it with stucco when we restucko the rest of the house. My question is how can we extend the stack? Is there an extender of somekind we can buy to put on top of the origional stack before we call the stucco guy. If so where would one go to buy it? Is it something my husband could do himself? And is it expensive? We are already spending so much money we really need to keep expenses down as much as possible. Thanks for your help.
