Fascia is one of those parts of a house nobody thinks about until a chunk of it is lying in the driveway. A rotted fascia board usually gets noticed when a piece of it falls off. By then, the board has been taking on water for a while, and the question is no longer just the board. It is what the water reached behind it.
This post covers what fascia is, why it rots, and what we found on a job in Camarillo where the homeowner reported a rotted board above the garage door after a piece fell off in the rain.
What fascia is and why it rots
Fascia is the trim board that runs along the edge of a roof, a deck or an overhang. It covers the ends of the framing behind it and gives gutters and trim something to attach to. Because it sits on an edge, it takes rain, runoff and splashback.
- Water getting behind the board. A gap at the top edge, failed caulk or missing flashing lets water run down the back side, where it does not dry.
- Paint that has failed. Once the paint cracks, bare wood soaks up water every time it rains.
- Water from above. A deck, balcony or roof edge right above the board sends water over it. If the roof edge is the problem, the roof needs fixing too, or the new board just starts the clock over.
- Corners and joints. Where the board meets a wall or another board is often where the rot starts.
The USDA Forest Service notes that for most decay fungi, the best conditions are wood moisture contents above fiber saturation, usually around 25 to 30 percent. In other words, wood that stays wet is wood that rots.
What we found over a garage in Camarillo
The homeowner reported that the board above the garage door was rotten, that a piece had fallen off during the last rain, and wanted it repaired before the storms started. The garage sits under a deck with a metal railing.
September 24: the first look
The photos from the first visit show the bottom edge of the board over the garage door broken down and crumbling, with soft, stringy wood and debris along its length, right above the top of the garage door.
October 19: opening it up
On October 19, the old board and covering came off along the length of the garage door. Behind it, the framing had dark staining and water marks. The worst of it was at the corners where the wood met the stucco wall, where the wood had broken apart.
Later that day, house wrap went on over the face of the framing.
October 26 and 27: putting it back
On October 26, flashing tape went on along the edges of the house wrap. By October 27, the new finish was up over the garage door and the light fixture was back on the wall.
Signs your fascia needs repair
- Paint that is peeling or bubbling along the board
- Wood that feels soft when you press a screwdriver into it
- Pieces breaking off or falling, especially after rain
- Dark staining or water marks on the board or the wall below it
- Gaps where the board meets the wall or another board
- Gutters or trim pulling away from the board
Why it is more than replacing one board
Fascia covers the ends of the framing behind it. If water has been getting past it, the framing can be stained or rotted too, and putting a new board over damaged wood just hides the problem until it shows up again. That is why the board comes off first and the wood behind it gets looked at before anything goes back up.
If there is a wall right next to it, the water can also get behind the siding or stucco. On this job, the worst rot was right where the wood met the stucco, which is exactly where you would expect it. Our post on siding water damage shows what that looks like behind siding, and cracked or soft stucco at a joint like this is a job for stucco repair.
Get it fixed before the rain
Rot does not get better on its own. It is not a fine wine. Every storm puts more water into wood that is already soft, and a board that has started to fall apart can let water into the framing behind it. If you see the signs above, get it looked at before the rainy season. Our post on preventing water damage at home has more checks like these.
FAQ
Can you just patch rotted fascia?
Small soft spots can sometimes be filled, but when the board is crumbling or pieces are falling off, it needs to come off. That is the only way to see whether the framing behind it got wet too.
What is the difference between fascia and soffit?
Fascia is the vertical board on the edge. Soffit is the flat surface underneath an overhang. Water damage on one often shows up on the other.
Does homeowners insurance cover rotted fascia?
Many policies treat rot from long term moisture as a maintenance issue rather than sudden damage, but it depends on your policy and the cause. Check with your insurer. Our post on what water damage repairs cost in Ventura County covers what drives the price if it ends up being out of pocket.
