Thinking about making my own Chimney Cap? Any Advice?
So I recently purchased a 1910 rowhouse in baltimore and there are 4 chimenys, neither one has a chimney cap. The issue is that they are all very large and pre-made caps would be over $160 each. Now, they chimneys are only used for venting and there are no working fireplaces in the home. I was thinking about just laying a piece of metal mesh down over the chimney to keep animals from going in. Then to take care of the rain, I want to just bend a piece of sheet metal similar to the picture I attached below ( please dont comment on my horrible mspaint skills ). The sheet metal would extend about 6" on either side of the chimney and I would attach it right to the brick with masonry screws. I am wondering if there is anything that could happen with my design or any reason this wouldnt work? Any tips or suggestions would be much appreciated.
