Basically the title. I discovered our furnace vent cap blew away when I found water dripping on my basement floor at the bottom of the riser.
Climbed up and checked and it appears to have about a 6 1/2 inch ID. I am guessing this is a "6 inch" duct. I am having a really hard time finding a 6 inch [or larger] vent cap without shelling out an unreasonable amount on Amazon. So question is:
Can I just, even temporarily [few months, til I feel like getting on the roof again], fit two elbows into a u and fix them to the outlet to keep water out for now?

Get a professional to fix it. Carbon Monoxide should not be trifled with.
