Catch wood rot early before it becomes expensive structural damage. Visible signs of fascia, soffit, and trim rot in Texas homes.
In our humid Texas climate, wood rot is the #1 silent destroyer of homes. It starts in places you don't look — under fascia boards, behind soffit vents, around door frames — and by the time you notice from the ground, the damage is often 3-5 times worse than what's visible.
Where to look: The horizontal trim board running along the bottom of your roof line. Especially around soffit vents and below corners.
What it looks like: Brown, gray, or black streaks that look like watermarks. Often shows as wavy patterns flowing down from above.
Why it matters: By the time stains show on paint, the wood underneath is usually 30-60% compromised.
Common cause: Failed gutter, clogged gutter overflow, missing drip edge under shingles.
Where to look: Door frames (especially exterior doors), window trim, deck boards, fascia boards, porch columns.
What to do: Press a screwdriver firmly into the suspect area. Healthy wood resists; rotten wood gives way easily.
Why it matters: Soft wood means active rot fungus. The structure is already weakened.
Where to look: Window trim, door frames, fascia, exterior siding edges, porch columns.
What it looks like: Paint that bubbles up, flakes off, or cracks in the same spot every 1-2 years even after re-painting.
Why it matters: Paint can't bond to wood that's swelling and shrinking from moisture.
Where to look: Door jambs, window sills, deck boards, exterior trim joints.
What it looks like: Hairline cracks growing wider over time. Sections of trim pulling away from the house.
Why it matters: Cracks are highways for moisture to enter wood.
Where to look: Ceilings near exterior walls (especially second floor), inside closets on outside walls, around windows.
What it looks like: Yellow, brown, or rust-colored circular or oval stains.
Why it matters: If you see water inside, the rot outside has progressed enough that water is making it through into your living space. This is usually a 2-4× more expensive repair.
The lesson: catching wood rot at sign 1 instead of sign 5 saves you $7,000+ on average.
If you see 2+ signs on the same area, or any single sign on multiple areas of your home, it's time for a professional inspection. Wood rot doesn't get better on its own — it spreads.
