GAS Opportunity!
I bought one of these, to measure focal distances, and other stuff.

It will also measure height using trig; aim at base, then at top, and it
calculates from inclination and two lengths.
Might not work directly here, through window, but can certainly measure distance to top and angle, then perhaps through
door to wall or something set under peak.
Pretty hard to use with small target in daylight. Works well for that at night.
