What's the difference between fascia and soffit boards?

Sacramento County and PNNL (read 2026-11-05) help you distinguish the roof-edge face from the panel underneath the overhang. “A flat board with a vertical face that forms the trim along the edge of a flat roof, or along the horizontal, or eaves, or sides of pitched roof.” (source) “Do you see vents in the soffits (the wood panel covering the underside of the eaves) as shown in Figure 2?” (source)

Should I replace the fascia board or will wood filler and paint work?

Home Repair Resource Center (read 2026-11-05) addresses replacement material when rot requires a new board, plus an older-home precaution. “If the fascia board itself has rotted and must be replaced, outdoor treated wood is best to prevent recurrence of this problem in the future.” (source) “Note: If your house was build prior to 1978, the fascia boards may have one or more coats of lead-based paint on them; if so, disturbing these surfaces can produce lead-based paint dust, which is a health hazard that poses a special threat to young children.” (source)

What causes fascia boards to rot?

Home Repair Resource Center (read 2026-11-05) describes the exposure problems in its example of fascia concealed by a gutter. “First, since it's always covered by a gutter, it is never exposed to sunlight.” (source) “Second, it is in an area that is constantly wet or damp.” (source)

What affects the cost of fascia board replacement?

Home Repair Resource Center (read 2026-11-05) identifies a possible addition to the work scope when gutter fastenings will not hold. “If, when you remove the gutters, the fascia is loose, and longer replacement nails don't seem to secure it adequately, then the ends of the roof rafters have probably rotted.” (source) “If this is the case, the fascia board must be removed completely to replace the rafter ends.” (source)

Should drip edge be tight to fascia or with a gap behind it?

PNNL (read 2026-11-05), section 4, gives a roof-edge detail to request when checking how flashing protects the fascia. “Drip edge is a typically L-shaped metal flashing installed along the edge of your roof between the roofing and the fascia (Figure 20).” (source) “The lower leg extends down at least 1.5 inches over the top of the fascia board.” (source) “The lower leg should not touch the fascia but should be set out from it a half-inch or so and the bottom edge of the lower leg should be flared out from the house to discourage water drops from wicking back behind the drip edge into the wood of the fascia board (Figure 22).” (source) “If there is a gutter along the roof edge, the front leg of the drip edge should come down into it, not behind it, to direct water into the gutter (Figure 23).” (source)
