What Is Fascia?
The fascia is the board nailed across the rafter tails, giving the roof edge a straight finished line and providing the mounting surface for gutters. It sits at the exact point where roof runoff, gutter weight, and wind meet, which makes it the most commonly rotted piece of exterior trim on a house. Water reaches it three ways: over the back of a clogged or badly pitched gutter, around a shingle edge that lacks drip edge metal, or wicking up end grain at corners and joints. Once softened, it loses grip on gutter spikes, the gutter sags, overflow worsens, and the rot accelerates — a feedback loop homeowners see as a pulling-away gutter, peeling paint, or a visibly wavy edge line. Repair is removing the gutter, cutting out rotted sections back to sound wood, priming all faces, and reinstalling with the drip edge lapping correctly over the fascia's top.
Important Distinction
Note: Fascia rot is usually a symptom, not the disease — the cause is typically missing drip edge, failed gutter slope, or shingle runoff behind the gutter, and replacing the board without fixing the water path repeats the rot.

Related To Fascia
Drip edge's whole job is to kick water past the fascia board; peeling paint or a rot line just below the roof edge usually means the drip edge is missing, short, or tucked behind the gutter instead of over it.
Gutters hang on the fascia, so a sagging or pulling gutter is often a symptom, not the problem - the fascia behind it has softened from years of overflow or a missing drip edge, and rehanging the gutter into rot fixes nothing.
Soffit is the horizontal underside of the roof edge, fascia the vertical face - and a stain on the soffit means water is already inside the edge assembly: by the time it shows underneath, the wood above has been wet for a while.
