need to close a chimney

[wreckinball]

my wife and I decided to make some renovations at home and among the many things we plan to take down the chimney, we don't use it anyway, so might as well have an aerodynamic roof. My question is how do I close the opening? I'm looking for a way in which it will remain closed and we won't have to think twice about it for as long as we're alive

You can either go for a concrete or metal cap for the roof. How long have you not used it anyway? But yeah, that aside, metal is the way to go if you're planning for a budget-friendly renovation, but if you want something more permanent then stick with concrete caps. Just expensive and I wouldn't do it to myself.

I guess clean the area first for debris or soot then use a chimney cap if you wanna seal the top for good. Use a high quality mortar for sealing, then add some insulation, smooth out surface. Don't forget to waterproof!

I capped one with concrete and flashed around it with metal before redoing the shingles. Asked for an update from the client (my brother in law) and no it hasn't leaked or budged in years. That's a win, right?

Afaik, capping the top will still leave the structure which can deteriorate over time.

If I were you, I'd better remove it. proper roofing work will give you a permanent closure that will not need attention again. You might want to consider checking local codes since some areas require permits for chimney removal.
