Houston roof maintenance
A Season-by-Season Roof Maintenance Checklist for Houston Homes
Houston is harder on roofs than almost anywhere in the country. Heat that cooks shingles from underneath, humidity that keeps decking damp, hail every spring, hurricanes every summer, and pine litter that never really stops falling.
What follows is what to check, when to check it, and which jobs genuinely need somebody insured. Most of it costs nothing.
In this guide
- The Houston roof calendar — what to do each season, at a glance
- Spring — hail season, and what it leaves behind
- Summer — heat, attic ventilation and the start of hurricane season
- Autumn — the most important season, and the one most people skip
- Winter — mild, but not nothing
- The pre-hurricane checklist
- Warning signs from the ground
If you read nothing else
- Autumn is the season that matters most. Gutters clogged going into winter is the single most common cause of interior damage here.
- Hail damage often does not leak for months. A spring storm can surface as a stain in October — long after the claim window has closed.
- Stay off the ladder. Around 500,000 people a year are treated for ladder injuries in the US, and most fatal falls are from ten feet or less. Nearly everything useful in this guide can be done from the ground.
The Houston Roof Calendar
Houston's roofing year is shaped by three things: hail season in spring, hurricane season from 1 June to 30 November, and leaf and needle fall through autumn. Everything below is timed around those.
| When | What it is for | Do it yourself | Get someone insured |
|---|---|---|---|
| Feb – Mar | Before hail season | Check the attic for damp or daylight | Full inspection; fix anything loose |
| Apr – May | Hail season | Photograph the roof from the ground after any storm | Inspection after hail, even with no leak |
| May | Before hurricane season | Clear ground-level drains; book tree trimming | Gutter clean; secure loose flashing and shingles |
| Jun – Aug | Heat and UV | Check attic temperature and airflow on a hot day | Ventilation assessment if the attic is stifling |
| Sep – Oct | Peak hurricane risk | Keep the pre-storm checklist ready | Post-storm inspection and documentation |
| Oct – Nov | Leaf and needle fall | Watch for gutter overflow in rain | Gutter clean and valley clearing — the important one |
| Dec – Jan | Winter rain and wind | Check ceilings after heavy rain | Repairs before spring, while schedules are open |
Twice a year is the working minimum — once in spring after hail season, once in autumn before the leaves drop. Add an inspection after any storm that brought hail or wind above about 50 mph.
March – May
Spring: Hail Season
This is the season that damages Houston roofs, and the damage is frequently invisible.
Hail does not usually punch holes. It bruises — crushing the granules on a shingle and shortening its life without breaking the surface. A roof hit in April can look perfectly normal from the driveway and start leaking in October.
That gap matters because most Texas policies have a filing deadline. By the time a stain appears on the ceiling, the claim window may have closed.
After any hailstorm
- Photograph the roof from the ground, including the date
- Check gutters and downspouts for granule build-up — granules in the gutter mean shingle surface has been lost
- Look at soft metal: vents, flashing, the mailbox, air-con fins. Dents there mean the roof took the same hit
- Check window screens and fence tops, which bruise visibly
Worth a professional look
- An inspection after hail, even with no leak — documentation dated close to the storm is what supports a claim
- Any roof already ten years or older
June – August
Summer: Heat, and the Start of Hurricane Season
Houston attics reach temperatures shingles were never rated against. Heat is the quiet killer here.
A poorly ventilated attic can run 140°F or more on a July afternoon. That heat cooks the shingles from underneath, warps decking and can take years off a roof without a single leak appearing.
Hurricane season opens on 1 June. Anything loose in June is a missing shingle in September.
From inside the house
- Go into the attic on a hot afternoon. If it is stifling and still, ventilation is inadequate
- Look for daylight around vents, and for rusted nail heads — both point at moisture
- Check whether soffit vents are blocked by insulation, which is common and easily fixed
- Watch for rising cooling bills without an obvious cause
Worth a professional look
- A ventilation assessment if the attic is stifling — often cheap to fix and it adds years
- Securing loose shingles and flashing before storm season proper
September – November
Autumn: The Season That Matters Most
Peak hurricane risk, then leaf and needle fall. This is the one to get right.
September is the most active month of the Atlantic hurricane season. Then, as the weather turns, the leaves and pine needles come down — and Houston's pine canopy makes this worse than most cities.
Pine needles are the underrated problem. They pack into valleys and behind chimneys, hold moisture against the shingle surface, and rot the decking underneath. Nothing shows until a ceiling stains, and by then it is structural.
From the ground
- Watch gutters during heavy rain — overflow at one corner tells you exactly where the blockage is
- Clear the bottom of downspouts where they discharge
- Check ceilings and upstairs rooms after every heavy rain
- Book tree trimming for branches overhanging the roof
Worth a professional look
- Gutter clearing and valley cleaning. If you do one paid job a year, this is it
- Post-storm inspection after any tropical system
- Pine needle removal if you are under a canopy
December – February
Winter: Mild, But Not Nothing
Houston winters rarely threaten a roof directly. What they do is find every weakness autumn left behind.
Sustained winter rain is the real test. Water that would run off a sound roof finds the failed flashing, the cracked pipe boot and the valley nobody cleared — and keeps finding them for weeks.
The occasional hard freeze matters too. Water sitting in a blocked gutter expands when it freezes, which pulls fixings away from the fascia.
From the ground
- Check ceilings after every prolonged rain, not just heavy ones
- Look for damp patches on exterior walls under the roofline
- Note any gutter that stays full after rain stops
Worth a professional look
- Repairs you have been putting off — winter is the quietest season for roofing schedules
- Anything found in autumn and deferred
Where you live changes the answer
Four Houston Micro-Climates
A roof in Kingwood and a roof in the Heights face different problems. Adjust the calendar to whichever of these you are in.
-
Under pine canopy
The Woodlands · Spring · Kingwood · Tomball · Magnolia
Needles fall year-round, not just in autumn, and they pack into valleys and behind chimneys where they hold moisture against the shingles. This is the one situation where quarterly clearing is genuinely worth it rather than twice-yearly.
-
Near the bay
Toward Galveston Bay · Clear Lake · the south-east
Salt in the air corrodes fasteners, flashing and any exposed metal faster than inland. Wind exposure is higher too. Inspect more often, and pay attention to metal components rather than just the shingle field.
-
Open, high-wind exposure
Newer subdivisions · open land · west and north-west edges
Without mature trees or neighboring rooflines to break the wind, edges and ridges take the full force. Wind lifts shingles from the perimeter inward, so starter strips, drip edge and ridge cap are what matter most here.
-
Inner-loop urban heat
Central Houston · the Heights · Montrose · inside the 610 Loop
Dense development and paving hold heat, so central Houston runs hotter than the suburbs and swings harder between day and night. That thermal cycling ages shingles faster. Attic ventilation matters more here than almost anywhere.
The Pre-Hurricane Checklist
Hurricane season runs 1 June to 30 November, with September the busiest month. Split the work: the useful preparation happens weeks ahead, not the day a storm is named.
May, or as early as you can
- Professional inspection and any outstanding repairs
- Loose shingles and lifted flashing secured
- Gutters and downspouts cleared
- Overhanging branches trimmed back
- Check your policy: deductible, and whether wind and hail are covered separately
Roofing schedules fill within hours of a storm being forecast. Anything you leave until then does not get done.
When a storm is forecast
- Clear loose debris from the roof and yard
- Bring in or secure outdoor furniture
- Photograph the roof and the exterior — dated before-images are the strongest evidence a claim can have
- Move vehicles away from trees
- Know where your policy documents are
Do not get on the roof or on a ladder ahead of a storm. Whatever you were going to fix is not worth the fall.
Warning Signs You Can See From the Ground
None of these require a ladder, and any one of them is worth a closer look.
- Granules in the gutters or at the downspout — the shingle surface is wearing away. Normal in small amounts on a new roof, not on an old one
- Shingles that look dark or patchy in places — often where granules have gone
- A wavy or uneven roof line — can indicate the decking has softened
- Gutter overflowing at one point in rain — a blockage above it
- Damp on exterior walls under the roofline — often failed flashing
- Ceiling stains, bubbling paint, or a musty smell upstairs — water is already inside
- Daylight visible in the attic — if light gets in, so does water
- Dents on soft metal — vents, flashing, the mailbox, air-con fins. Hail hit the roof too
A ceiling stain is not the start of the problem. It is the point at which the problem became visible — usually months after the water first got in.
If you would rather not do it yourself
A roof tune-up starts at $199 and covers the sealing, the shingle replacement and the photographed inspection this guide describes.
