On roof raises, why do people tuck the sheet metal behind the rub rail?
On most Blue Bird roof raises I see, people put a lot of work into tucking the sheet metal under the drip awnings up top, but then also tuck it under the rub rail below the windows. It seems like water would sheet off better if the metal went inside the drip awnings and then OUTSIDE of the rub rail down below, so that no water worked its way inside the rub rails.
Also, this would be much easier for me to do than try to bend the metal to get it inside both the awnings and the rub rails.
Is there a functional reason why I shouldn't overlay the new metal over the rub rail?
