I am looking for a umbrella cap to cover my 15 inch attic exhaust fan
Many people just use large black trash bags secured with duct tape or bungi cords. Black bags won't deteriorate as fast as the white ones with the UV rays of the sun and should last one full winter.
If you're concerned about the neighbors complaining about the lack of asthetics....I can't help you.
I never cover attic vents nor recommend them to be covered, because a properly vented attic all year long ensures moisture removal from the attic area and from the insulation. Also if you have shingled roofing, each nail point extending through the sheeting will condense moisture and drip into the insulation in a non vented attic space. This happens many times each winter when the air temp and the moisture content collide on the dew point scale. It does NOT happen daily.
The nails conduct the warmth to the outside, cool down and attract the moisture from the non vented air on their exposed length and slide down to the tip dripping into the insulation. Moisture detracts from the insulations ability to do its job, and that's to insulate the living space from abnormally cold or hot temperatures.
