Seasonal Roof Maintenance for Missouri Homeowners

A practical season-by-season roof and exterior checklist for St. Louis area homes — what to do, when, and what genuinely needs a professional.

Published · Eagle Revolution, O’Fallon MO

Why Missouri is harder on roofs than people think

We get the full set here: hail in spring, genuine heat and UV in summer, heavy leaf load in fall, and a freeze-thaw cycle all winter that works on every small opening. Very few climates hit a roof with all four.

None of this requires much work. It requires the right work at the right time.

Spring — after the storms

  • Walk the perimeter and look for shingle pieces or granule piles at the downspouts.
  • Check the soft metal — gutters, AC fins, window wraps — for hail dimples.
  • Clear the gutters of winter debris before spring rain arrives.
  • Look at the ceiling in every room, including closets, for new staining.
  • If a real hail event came through, get a professional inspection and document the date.

Summer — heat and ventilation

  • On a hot afternoon, put your hand on the attic hatch. If the attic is brutally hotter than it should be, your ventilation isn't keeping up — and that is quietly shortening your roof's life every single day.
  • Check that soffit vents aren't blocked by insulation. This is extremely common and easy to fix.
  • Confirm bathroom and kitchen fans vent outside, not into the attic. Dumping humid air into the attic is one of the most damaging things a house can do to itself.
  • Trim branches back off the roof. Abrasion and constant shade both cause problems.

Fall — the most important season

If you only do one thing a year, do this one.

  • Clean the gutters thoroughly after the leaves finish dropping. Clogged gutters in a Missouri winter are how ice dams start.
  • Check that downspouts discharge well away from the foundation.
  • Look at flashing around chimneys, skylights, and where roof planes meet walls. That's where the majority of leaks begin.
  • Check attic insulation depth and that it isn't packed into the soffits.

Winter — mostly watch

  • After heavy snow, look for icicles and ice building at the eaves. That's an ice dam forming, and it's an insulation and ventilation signal.
  • Watch for interior water stains, which show up during thaws rather than during the snow.
  • Stay off the roof entirely. Ice plus pitch is how people get badly hurt.

What's worth a professional

Gutter cleaning and visual checks are homeowner work if you're comfortable on a ladder. Flashing inspection, ventilation assessment, and anything after a hail event are worth having someone insured look at — partly for expertise and partly because they're the things you can't evaluate from the ground.

Our inspections are free and you get the photos of what we actually found. If the answer is "your roof is fine, see you in a couple years," that's a perfectly good outcome for both of us.

Common Questions

How often should a roof be inspected?
Twice a year is the standard answer — spring and fall — plus after any significant hail or high-wind event. For most homes an honest annual look is enough, as long as you also check after storms. What matters more than frequency is that somebody actually gets eyes on the flashing details, not just the field of the roof.
What causes ice dams and how do I stop them?
Heat escaping into the attic melts snow on the upper roof; the water runs down to the cold eave and refreezes, building a dam that forces water back up under the shingles. The fix is air sealing and attic insulation plus proper ventilation — not roof rakes, not heat cables. Those treat the symptom.
Do gutter guards actually work?
Good ones meaningfully reduce how often gutters need clearing, especially under heavy tree cover. No guard eliminates maintenance entirely, and anyone claiming otherwise is overselling. On a wooded lot they are usually worth it. On an open lot with no overhanging trees, often not.
