We're having to repaint some weathered fascia. I've bought the sander and am ready to paint, but my dad said that unless we get a drip edge installed here, it will just happen again. But everything I see online about installing drip edges seem to be geared toward shingle roofs.
Looking at the picture, does it look possible for us to install a drip edge ourselves? Or do the tiles need to be completely removed, a bigger job than we can do?
Any other suggestions about preventing weathering?
