Actually, that's a pretty good way to go. As long as it's installed properly (directions for the diyer are easy to find if needed) it will not rot the wood behind it, or cause rot or trap water. It's a good way to go and I haven't had to touch mine in over 20 years. This summer I insulated a back porch and when I removed the soffit and facia, the wood was as pristine as the day it was last painted. And still tightly nailed in place.
