Hello everyone. I have my pellet stove vent coming straight out of the wall in my house. It's a little over 21 inches from the tip of the jet cap to the thimble. Last year I had a big chuck of ice come down and bend the vent pipe. My fault for not cleaning the roof sooner. Does anyone see a concern if I was to build a gabled awning out over the pipe? It would be at least 4 feet above the pipe itself. At 350 for a new pipe and cap I would like to prevent this from ever happening again. Thanks,
