Fall Storm-Season Gutter Checklist for Austin Homes

By Austin Rain Gutter Repair · September 7, 2026 · 7 min read

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

A small kit to keep in the garage

Most fall gutter trouble starts small, and a few cheap items let you deal with it the same evening instead of waiting a week.

• Downspout straps and short exterior screws. A loose downspout is the first thing a gust takes.
• A tube of polyurethane gutter sealant. For a temporary dab on a dripping end cap until it can be done properly.
• Two spare rigid extensions. The mower will find one before November.
• Heavy zip ties. Enough to hold a separated elbow together through one storm.
• Work gloves and a bucket with a hook. For pulling a clump out of a downspout top on a single-story run.
• A charged phone. For photos before and after anything happens.

None of this replaces a proper repair, but it keeps a small problem from turning into a wet slab while you wait.

If you have to go up the ladder

Most of the walk-around is done from the ground, and that's on purpose. If you do climb, keep it to a single story and keep it simple. Set the ladder on firm, level ground, never on wet clay or a sloped bed. Use a standoff so the ladder doesn't rest on the gutter. Keep your hips between the rails and move the ladder rather than reaching. Have someone hold the base. Skip it entirely when the roof or the ground is wet, when it's windy, or when the job is a second story. Those are the jobs worth paying for.

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 your insurance agent if it looks like a claim, and arrange gutter repair, saying it's storm damage so it can be prioritized. 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.

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.

After the first big storm

Do a short repeat of the walk-around once the first serious fall storm has passed. Look for anything that moved: a downspout that swung off its strap, an extension that floated away, a run that now sags. Check the ground at each outlet for fresh channels. Note any run that spilled over, and where. A two-minute look the morning after tells you more than a dry-day test ever can. Add anything you find to the list for the December cleaning visit, so it all gets handled from one ladder setup.

Common questions

When should I do a fall gutter check in Austin?

Mid-September is ideal, before the main flash-flood window from late September into early November. A dry week gives you time to fix small things like straps and extensions before the storms test them.

Do I need to clean gutters before the fall storms?

Usually not. Live oaks drop in March, and the cedar elms and pecans don't drop until November and December, so September gutters are often close to empty. Check that each downspout flows with a hose and save the full clean for December.

What should I fix first if I find several problems?

Anything that sends water at the slab or lets a gutter blow off: loose downspouts, missing extensions and runs pulling off the fascia. A dripping corner away from walkways and the AC can usually wait for a proper repair visit.
