There are a few different terms that can be used for the piece of wood that sits under your gutters - fascia, soffit, and bargeboard are a few. They all basically refer to the same thing - the trim that goes along the edge of your roof and wraps around to cover up the area where your roof meets your walls. It's an important part of your roofing system because it protects your home from water damage, and it's also important to make sure that it's in good condition so that it can do its job properly.

The wood under the gutter is called fascia. It's a board that runs parallel to the roof, and it helps to support the gutter as well as hiding any exposed nails or screws. If your fascia is damaged, you'll need to replace it before you can fix your gutters.
