OK, the thought of "a mess of steaming ****" on my roof don't sound so
good but it could work.

Why not give it a try and let us know how long it takes for your
wife/significant other/dog/neighbor to move? *:)

OK, Semester exam for Frogwatch Fiziks. You have 24 hours to decide
whether or not this idea will work (there is no right or wrong
answer). Regardless of your answer, support it with relevant
calculations. You will be graded on your methodology. SEE, THIS IS
HOW PHYSICS SHOULD BE TAUGHT.
