The Complete Seasonal Gutter Maintenance Checklist for Houston

Houston gutter maintenance revolves around four key moments: a deep cleaning in February-March after live oaks drop their leaves, a full storm-readiness check before hurricane season opens June 1, quick inspections after every major summer and fall storm, and a final cleanout after autumn leaf drop finishes in late November. Follow that rhythm — plus a monthly glance at pine needle buildup, which happens year-round here — and your gutters will be ready for the 50+ inches of rain the National Weather Service says Houston receives in a typical year.

Houston doesn't have four northern-style seasons; we have storm season, hot season, a brief cool season, and pollen season. A generic maintenance calendar written for Ohio will have you cleaning at the wrong times and skipping the moments that matter most. This checklist matches the work to Houston's actual weather and — just as important — Houston's actual trees.

Why Doesn't a Northern Maintenance Calendar Work in Houston?

Three local realities break the standard advice:

Live oaks drop their leaves in spring, not fall. Houston's most common shade tree holds its leaves through winter, then sheds nearly all of them over a few weeks in February and March — right before spring storm season. A home under live oaks that only gets a fall cleaning enters the stormiest part of the year with clogged gutters.
Pine needles fall year-round. Pines shed continuously in every season, and needles are the single worst gutter-clogging material: they mat together, slip through wide-mesh screens, and wick water into dams.
Our heaviest rain has a schedule. Spring frontal storms (March-May) and hurricane season (June 1 through November 30, peaking August-October) are when a clogged gutter does real foundation damage. Maintenance has to land before those windows, not after.

What Does the Houston Gutter Year Look Like at a Glance?

Season	What's Happening in Houston	Gutter Priority
December - January	Cool, occasional freezes; trees mostly dormant	Visual inspection; check for freeze-popped seams
February - March	Live oak leaf drop; oak pollen and catkins begin	Deep clean — the most important cleaning of the year
March - May	Severe spring thunderstorms; heavy pollen mats	Pre-storm check: flush downspouts, tighten hangers
June - July	Hurricane season opens; near-daily afternoon storms	Storm readiness; quick checks after each big rain
August - October	Peak hurricane season; strongest tropical threat	Keep gutters clear; inspect immediately after storms
November	Fall leaf drop (sweetgums, sycamores, red oaks); pine needles continue	Post-leaf-drop cleanout before winter

What Should You Do in Winter (December - January)?

Houston's mild winter is inspection season. With many trees bare and no urgent storm threat, this is the easiest time to actually see your gutter system.

Walk the perimeter and sight along every gutter run for sagging, gaps, or misalignment
Confirm every downspout is connected and discharging away from the foundation — extensions often get knocked loose during fall lawn care
After any hard freeze, check for popped seams or split joints; trapped water expands as it freezes
Look for tiger-striping or streaks on the gutter face (signs of past overflow)
Book any needed repairs now, before spring — this is the slow season, so scheduling is easy

What Should You Do in February and March?

This is the one most Houston homeowners get wrong. Live oaks drop their leaves in late winter and early spring — roughly February through March — not in autumn. If your street is lined with live oaks, the biggest debris load of your entire year lands in these few weeks, immediately followed by oak catkins (those brown tassels) and a film of yellow pollen that turns to sludge in a wet gutter.

Schedule your most thorough cleaning of the year for late March, after the oak drop finishes
Scoop all runs, then flush every downspout with a hose until flow is strong and clear
Clear catkins and pollen mats off gutter guards — even good mesh guards need their surface brushed after oak season
Reseal any joints that wept over winter and tighten any loose hangers while you're up there
If you'd rather not handle the nastiest cleaning of the year yourself, this is the one to hand to our gutter cleaning service ($150-$300 for most homes)

How Do You Get Ready for Spring Storm Season (March - May)?

Spring frontal systems bring some of Houston's most intense short-duration rainfall — the 2-4-inches-in-an-hour storms that overwhelm any partially blocked system.

Verify gutters are clean and downspouts flow freely (done, if you followed the February-March step)
Check that splash blocks and downspout extensions are seated and aimed away from the slab
Flush underground drain outlets and confirm pop-up emitters open freely
Watch one heavy rain from the window: overflow at any point marks your problem spot
Look for standing water in gutters a day after rain — that's a pitch problem or a partial clog, and it breeds mosquitoes

What About Hurricane Season (June - November)?

Hurricane season officially runs June 1 through November 30, with Houston's highest risk historically in August through October. Your gutters should enter June clean, tight, and tested.

Early season (June - July):

Confirm every hanger and bracket is snug — wind works loose hardware into failures
Trim branches hanging within 10 feet of the roofline before a storm does it for you
After each major thunderstorm, do a 60-second walk-around for new sags, disconnected downspouts, or debris

Peak season (August - October):

Keep gutters as clear as possible at all times — sustained tropical rain gives a clogged system nowhere to hide
Before a named storm arrives, do a final visual check and secure loose yard items that could strike the gutters
After any tropical system, inspect immediately: look for pulled-away sections, dents, missing extensions, and storm debris
Check gutters for shingle granules — a heavy layer after high winds can indicate roof damage worth a professional look

What Should You Do After Fall Leaf Drop (November - December)?

Houston's deciduous trees — sweetgums, sycamores, red oaks, elms — drop through November. Pine needles, as always, keep coming.

Schedule the year's second major cleaning once leaf drop is mostly finished, typically late November
Pay special attention to pine needles, which mat into dams that leaves alone don't create
Clean guard surfaces and check that fine debris hasn't accumulated along the guard edges
Confirm the system is tight and draining before winter cold snaps arrive
This is also a smart time for a professional inspection, so any repairs happen during the calm season

What Rules Apply Year-Round?

Never ignore standing water. Water sitting in a gutter days after rain means a clog or a pitch problem — and in Houston, a mosquito nursery.
Check after every major storm. Sixty seconds of walking the house catches small problems while they're still small.
Keep trees trimmed. Branches within 10 feet of the roof are next season's clogs.
Never lean a ladder against the gutter. Use a standoff — one dented run can create a permanent low spot.
Know your cleaning frequency. Heavily treed lots need 3-4 cleanings a year; lightly treed lots may need 2. Our guide to how often you should clean your gutters helps you calibrate.
Consider guards if you're cleaning constantly. Quality micro-mesh gutter guards can turn this whole checklist into one annual inspection.
