Fall Storm-Season Gutter Checklist for Austin Homes
Austin doesn't have a hurricane season, but it has something close: the fall flash-flood window. From mid-September into early November, tropical remnants and stalled cold fronts pile up against the Balcones Escarpment, and the results are on the record. The Halloween 2013 flood, the October 2015 flood, and the October 2018 Llano River flood that turned Lake Travis brown for weeks were all fall events. October is Austin's second-wettest month after May. This is the week to walk around the house.
The ten-minute walk-around
You don't need a ladder for most of this. Do it from the ground with your phone, and photograph anything that looks wrong; the pictures are useful for a repair estimate and for an insurance conversation later.
1. Hangers. Sight down each run from the end. A run that dips in the middle or has pulled away from the fascia at the top has hangers backing out. Spike heads standing proud of the gutter face are the giveaway on 1990s systems. Wind gets under a loose gutter, and Hill Country thunderstorms come with straight-line gusts.
2. Downspout straps. Each downspout should be strapped to the wall every eight feet or so. Look for a downspout that moves when you push it, or one that has already separated at the elbow under the gutter. A loose downspout is the first thing a gust takes.
3. Fascia. Look at the board behind the gutter, especially under corners and below downspouts. Peeling paint in a band along the roof edge, a dark gap at the top of the gutter, or wood that looks swollen means the board is soft. New hangers won't hold in it.
4. Flow. Run a hose into the gutter at the far end of the longest run for five minutes. Water should reach the downspout and come out the bottom. If it pools or spills over mid-run, that's pitch; if the downspout barely trickles, that's a clog; if it comes out the bottom fine but the gutter still overflows, that's capacity. Why gutters overflow in Austin rain sorts those out.
5. Extensions. Every downspout should end at least four feet from the house on ground that slopes away, or in a drain. Extensions that the mower has knocked off go back on now. On a limestone slope, look for a channel where last spring's water ran.
6. The roof edge. From the ground, look at where the shingles or metal panels meet the gutter. Shingles should overhang the gutter by half an inch to an inch, with a drip edge under them. Water stains on the fascia behind a gutter mean water is getting behind it. On a metal roof, look at whether the front lip of the gutter sits below the panel edge; if the gutter is level with it, water will clear it in a burst.
7. The trees. Limbs over the roof are the fall problem nobody puts on a gutter list. A live oak limb that's been resting on the roof all summer takes the gutter with it in a storm. Trim anything touching the roof.
What to fix now versus after
| Found | Do it now | Fine to wait |
|---|---|---|
| Loose downspout or separated elbow | Yes, it's a $5 strap or a $120 fix | |
| Gutter pulled off the fascia | Yes, before the wind finishes the job | |
| Extensions missing | Yes, $25–$80 each | |
| One corner dripping | Yes, unless it's over a walkway or the AC | |
| Mid-run sag | Yes if it's holding water | |
| Soft fascia | Yes; it gets worse with every storm | |
| Leaves in the gutter | Only if the downspout is blocked | The big clean is in December |
A note on cleaning in September
September is not the cleaning season here. Live oaks dropped in March, the cedar elms and pecans don't drop until November, and the gutters are as empty now as they'll be all year. If the hose test shows a blocked downspout, clear it; otherwise save the money for the December clean. When to clean gutters in Austin has the calendar.
If a storm gets there first
Photograph the damage before anyone touches it. Secure a loose downspout with a strap or a zip tie so it isn't hitting the slab. Don't climb on a wet roof. Then call for gutter repair and say it's storm damage; it goes ahead of routine work. If a limb has taken the gutter and part of the roof edge with it, the roofer goes first and the gutter goes back on after; we can coordinate the two.
Why this matters more than the patio
A downspout that's off the house in a two-inch-an-hour storm puts hundreds of gallons at one corner of the slab. On clay in Pflugerville that corner heaves; on limestone in Steiner Ranch it washes out. Ten minutes with a hose and a strap in September is the cheapest thing you'll do for the house all year.
