I have to clean the eaves of my house myself because nobody I hire will believe me that you can't point a pressure washer at the eaves without water getting inside the walls. "I'll just avoid the vents" doesn't work when you can see daylight between the roof and the wall all around the house.

I'm guessing you don't live in a place with tropical storms or really severe weather.

Where I am your house would flood when 80mph+ winds blow the rain up your walls.
