Soffit and fascia
The two boards that decide whether everything else holds
Fascia and soffit are the parts of a roof people only notice when they are painting. They are also the reason gutters fall off, the reason ridge vents do not work, and the most common way squirrels get into an attic.
Why they rot here
Water gets behind a gutter and onto the fascia whenever there is no drip edge or gutter apron at the eave, which is most older houses in this market. Add a freeze-thaw winter that drives moisture into every open grain end, and a painted wood fascia with no metal above it has a predictable life.
Soffit rots for a different reason: warm, moist air from the house that should be leaving through the ridge condenses on cold sheathing at the eave, and the moisture ends up in the overhang. That is why a soffit can be soft on a house with perfectly good gutters.
What wrapping hides
Aluminum wrap over fascia and vinyl soffit panels are a reasonable finish over sound wood: they stop the painting cycle and they hold up well. Installed over wood that is already wet, they are a lid. The wood keeps rotting, invisibly, and the first sign is a gutter that comes off the house with a section of fascia still attached to it.
- Ask what is behind the wrap on any house where the trim is already covered. A screwdriver in an inconspicuous spot settles it in seconds.
- Wrap needs a drip edge above it, or water runs down between the metal and the wood, which is the worst of both.
- Vinyl soffit has to be vented where the attic needs intake, and solid panels in the wrong place disable ventilation as effectively as insulation stuffed into the eave.
- Rot at the rafter tail is a different job from rot in the fascia board. If the tails are gone, the fix is structural carpentry and it is worth knowing that before the trim goes back on.
The ventilation half of the job
Attic ventilation is an intake-and-exhaust pair. Ridge vent is the exhaust; vented soffit is almost always the intake. A roof with a continuous ridge vent and blocked soffits pulls its make-up air out of the house instead, which costs you conditioned air in both seasons and does nothing for the attic.
Find out whether there is intake at all
Some houses here never had vented soffit. Others have it, painted shut, or blocked from above by insulation pushed into the eave.
Open the path
Vented panel, and baffles at the eave so insulation cannot slide back into the airway. This is usually the cheapest meaningful improvement available on an older roof.
Match exhaust to intake
More exhaust than intake is not better. It just pulls air from the easiest available place, which is the house.
Check it from inside
On a cold day, daylight at the eaves and no frost on the underside of the sheathing is what working ventilation looks like.
Soffit and fascia work is best done at the same time as a roof or a gutter replacement. The gutter is already down, the eave is already open, and the drip edge that stops it happening again goes on while the roof edge is accessible.
Animals
A soft fascia board or an open soffit corner is an invitation, and squirrels in particular will widen a gap into an entrance. The order of operations matters: the animals come out first, then the hole gets closed. Closing it first traps them inside the overhang, which becomes a worse problem than the one you started with.
Gutter pulling away, or a soffit panel hanging down at a corner?

No, and any repair that leaves the gutter hanging in place is working around the damaged section rather than replacing it. The gutter comes down, the board is replaced, and the gutter goes back on hidden hangers into fresh wood.
Should I wrap the fascia or paint it?
Wrapped aluminum over sound wood ends the painting cycle and performs well with a drip edge above it. Painted wood is repairable, matches a historic elevation better, and needs maintaining. Both work; wrapping over wet wood does not.
How do I know if my soffits are actually venting?
Look up at them: you should see either continuous perforation or vented panels at intervals. Then look from the attic at the eave: if you cannot see daylight and there are no baffles, the intake is blocked whatever the panels look like from outside.
Is this a roofing job?
It sits between roofing and carpentry, which is why it often falls between two contractors. It belongs with the roof and gutter work, because the detail that keeps it dry — the drip edge and the gutter apron — is roof work.
