I just bought one of these flood lights from amazon:
https://www.amazon.com/gp/product/B00OJOMMYK/ref=oh_aui_detailpage_o05_s00?ie=UTF8&psc=1
The flood light is staked to the ground to light up a joy sign I have (this can be seen also here: https://www.amazon.com/Teak-Isle-Christmas-Nativity-Yard/dp/B00CFNFD5M/ref=sr_1_1?s=lawn-garden&ie=UTF8&qid=1482256657&sr=1-1-spons&keywords=joy+christmas+sign&psc=1). It does a good job of lighting the sign up but…
I also don't want the extra light hitting the house as I have a few of those laser lights that light up the house. Is there a top cover or shield to eliminate the extra light from this flood light?
In addition, what can I do to stop the extra light hitting the house and only focus it mainly on the sign. Can I build or use something to stop this? Please note I am in Michigan with extremely cold and snowy weather so I cannot use anything to cover the top.

You need barn doors. Those are the funny black "cards" found on all four sides of theater lighting.
You dont need an actual product; feel free to improvise them any way you can, say with plywood or old election signs. If they are straight vertical, and thin, they won't accumulate much snow.
