Fascia is the long trim board that runs along the edge of your roof, right behind the gutters. It closes off the ends of the rafters, gives the roofline a finished look and, most importantly for this post, is what your gutter hangers screw into. When it rots, gutters start to sag and pull away, water gets where it shouldn't, and a simple gutter job turns into a gutter and fascia replacement. Here's what to look for and what to expect.
Why fascia rot is common around Baton Rouge
NOAA's 1991–2020 normals put Baton Rouge's average rainfall at about 61.94 inches a year, with rain in every month. Wood that stays damp for long stretches, in heat that averages highs above 90°F in July and August, is a good environment for rot.
Age plays a role too. According to Census ACS 2024 estimates, the median home in the City of Baton Rouge was built in 1976, and Port Allen (1964), Baker (1979) and Denham Springs (1980) have similarly older housing. Many of those homes have original or long-painted wood fascia that has seen decades of wet seasons. Newer homes can rot too, especially when gutters have been overflowing for years.
What causes fascia to rot behind gutters?
- Clogged gutters. When leaves and debris block the trough or downspout, water backs up and spills over the back edge, straight onto the fascia.
- Poor pitch. Gutters that sag or slope the wrong way hold standing water against the board.
- Leaking seams and end caps. Sectional gutters can drip at every joint, wetting the same spots each storm.
- Missing or short drip edge. If roof water can run behind the gutter instead of into it, it soaks the top edge of the fascia. Gutters are normally hung so the drip edge directs water into the trough.
- Failed paint or caulk. Once the finish cracks, bare wood wicks up moisture.
- Undersized gutters. In heavy rain, a small gutter overflows, sometimes over the back. See 5" vs 6" gutters for Baton Rouge rain.
Signs of rotted fascia
You can spot most of these from the ground or a short ladder:
- Peeling, bubbling or flaking paint along the roof edge
- Dark stains or streaks on the fascia or the soffit below
- Gutters that sag, pull away from the house or leave a gap at the top
- Loose gutter hangers or spikes that won't stay tight
- Soft, spongy or crumbling wood when pressed with a screwdriver
- Mold, mildew or moss on the trim
- Holes or gaps where birds, squirrels or insects get in
- Water stains on the soffit or exterior wall under the gutter
If you only see paint problems, the wood underneath may still be sound. Soft wood or hangers that won't hold usually mean the damaged section needs replacing.
Can you just rehang the gutters?
Not on rotted wood. Screws and hidden hangers need solid fascia to grip. Rehanging gutters on soft boards may look fine for a few weeks, then pull loose under the weight of water in the next heavy storm. That's why installers usually inspect the fascia when they take old gutters down, and why many quotes list fascia repair as a separate line item or an allowance.
What gutter and fascia replacement involves
The process varies by company, but crews usually follow a sequence like this:
Remove the old gutters
Taking the gutters down exposes the full length of the fascia so the installer can see how far the rot goes.
Probe and mark the damage
Soft sections are marked out. The installer also checks the ends of the rafters behind the fascia; if rot extends further into the roof structure, the scope and the type of contractor needed may change, so ask what they find.
Replace the damaged boards
Rotted sections are cut out back to solid wood and new boards fitted. Some homeowners also choose to wrap fascia in aluminum or use a moisture-resistant trim material to cut down on future painting.
Prime, paint or wrap
Exposed wood is sealed so it doesn't start absorbing water again.
Hang new gutters with proper pitch
New seamless gutters are hung with hangers spaced to carry heavy rain, sloped toward the downspouts, and set so the drip edge sends water into the trough.
How much does fascia repair cost?
Typical ranges from cost guides, 2023–2026. These are estimates, not quotes:
| Item | Typical range |
|---|---|
| Fascia replacement | $5–$12 per ft |
| Old gutter removal | $1–$2 per ft, or $150–$300 total |
| Seamless aluminum gutters, Baton Rouge (HomeBlue, 2025) | $5.90–$10.30 per linear ft installed |
| Installed aluminum, Baton Rouge: 150 / 200 / 250 ft | $880–$1,550 / $1,180–$2,060 / $1,470–$2,580 |
| Two-story add-on | +$1–$3 per ft |
As a rough illustration only: if 40 feet of fascia needs replacing, the fascia portion at $5–$12 per foot would come to about $200–$480 before the gutters themselves. The sources disagree, and the real price depends on how much wood is damaged, footage, stories, material, downspout count and any drainage work. You'll only know the true extent once an installer measures on site, and sometimes once the old gutters come down. Our gutter installation cost guide has the full table.
How to keep new fascia from rotting
- Keep gutters and downspouts clear, especially after heavy leaf or needle drop. Gutter guards can cut down on clogs.
- Make sure gutters are sized for heavy rain and sloped toward downspouts.
- Touch up paint and caulk on wood trim before cracks let water in.
- After big storms, check for gutters pulled loose by wind or falling limbs.
- Choose seamless gutters to reduce the number of joints that can drip.
Repair or replace?
If the gutters themselves are sound and only a short stretch of fascia is soft, a repair may be enough: the installer pulls that section, replaces the board and rehangs. If gutters are leaking at many seams, undersized or sagging along most of the house, replacing gutters and damaged fascia together is often the more practical route.
