What Winter Did to Your Roof: The Spring Inspection Checklist for St. Louis Homes

If you’ve lived in the St. Louis metro area for even a single winter, you already know the drill: freezing rain in December, a surprise ice storm in January, heavy wet snow in February, and those wild temperature swings in March that can go from 20°F to 60°F in the same week. It’s the kind of weather that builds character—and quietly tears apart a roof.

Every spring, the team at Family First Exteriors fields calls from homeowners across Creve Coeur, Des Peres, Wildwood, Ellisville, and throughout the greater St. Louis area who are discovering damage they never saw coming. A small leak in the attic. Shingles scattered in the backyard. Gutters sagging under the weight of months of debris.

The good news? Most winter roof damage is fixable—if you catch it early. This guide walks you through a practical spring inspection checklist so you can identify problems before they become expensive emergencies.

Why St. Louis Winters Are Especially Tough on Roofs

Not all winters are created equal, and the St. Louis climate is particularly punishing for residential roofing systems. The region sits in a unique zone where Arctic cold fronts collide with warm, moist air from the Gulf of Mexico. That collision produces a mix of precipitation types—sleet, freezing rain, heavy snow, and plain old rain—sometimes all in the same storm.

The real damage, though, comes from the freeze-thaw cycle. When water seeps into tiny cracks in your shingles, flashing, or sealant during a mild afternoon and then freezes overnight, it expands. That expansion forces those tiny cracks wider. Multiply that by dozens of freeze-thaw cycles over a single winter, and you can end up with serious structural vulnerabilities that are invisible from the ground.

Ice dams are another common problem for St. Louis homes, especially older homes in neighborhoods like Kirkwood, Webster Groves, and Ballwin where attic insulation may not meet modern standards. When heat escapes through the attic, it melts snow on the upper portion of the roof. That meltwater flows down to the colder eaves, refreezes, and creates a dam that traps water behind it. That standing water has nowhere to go but under your shingles and into your home.

Your Spring Roof Inspection Checklist

You don’t need to climb a ladder to start this process. In fact, we recommend keeping your feet on the ground and calling a professional for anything that requires getting up on the roof. Here’s what to look for, broken down by area.

1. Shingles and Roofing Material

Walk the perimeter of your home with a pair of binoculars and look up at the roof surface. You’re scanning for shingles that are cracked, curled at the edges, buckling, or missing entirely. Pay special attention to the south-facing slopes, which take the most direct sun exposure and tend to age faster.

Also check the ground and your landscaping beds for granules—those small, sand-like particles that coat asphalt shingles. A moderate amount of granule loss is normal over time, but if you’re seeing heavy accumulation in your gutters or at the base of your downspouts, it’s a sign that winter weather has accelerated the aging of your roof.

2. Flashing Around Penetrations

Flashing is the metal (usually aluminum or galvanized steel) that seals the joints around chimneys, vents, skylights, and where the roof meets a wall. These are the most leak-prone areas on any roof, and winter’s freeze-thaw cycles can cause the caulking or sealant around flashing to crack and pull away.

From the ground, look for flashing that appears bent, lifted, or rusted. If you have a chimney, check the step flashing along its sides—this is where water intrusion most commonly starts on St. Louis homes.

3. Gutters and Downspouts

Your gutter system takes a beating in winter. Ice accumulation can pull gutters away from the fascia board, and the weight of wet debris can cause sections to sag or separate at the seams. Walk around your home and look for gutters that are hanging away from the roofline, joints that have separated, or visible rust and corrosion.

Make sure your downspouts are still firmly attached and directing water at least four to six feet away from your foundation. Improperly draining gutters are one of the leading causes of basement water issues in the St. Louis area—a problem that starts at the roof but ends up costing thousands to fix below grade.

4. Soffit and Fascia

The soffit (the underside of your roof’s overhang) and fascia (the vertical board at the roofline where gutters attach) are easy to overlook, but they play a critical role in protecting your attic from moisture and pests. Look for peeling paint, soft spots, visible rot, or holes. Woodpeckers and squirrels are common culprits for soffit damage in wooded St. Louis County neighborhoods, and winter moisture can accelerate existing decay.

5. Attic and Interior Signs

If you can safely access your attic, take a flashlight up there on a dry day. Look for water stains on the underside of the roof deck, daylight coming through gaps or cracks, and any signs of mold or mildew. Check the insulation—if it’s damp, compressed, or displaced, that’s a strong indicator of a leak.

Inside your living space, look at the ceilings in rooms directly beneath the attic. Water stains, bubbling paint, or a musty smell can all point to roof-related moisture problems that developed over the winter months.

6. Nearby Trees and Overhanging Branches

Winter storms can leave broken branches hanging over your roof, ready to fall in the next strong wind. Overhanging limbs also deposit leaves and organic debris that trap moisture against the roof surface, promoting moss growth and premature shingle deterioration. Trim branches back to at least six feet from the roof edge.

When to Call a Professional

A ground-level visual inspection is a great first step, but it has limits. There are issues that only a trained roofing professional can identify—problems with the roof deck, deteriorating underlayment, compromised ventilation, or subtle storm damage that doesn’t show obvious symptoms from 30 feet below.

At Family First Exteriors, we provide thorough roof inspections that go beyond what you can see from the ground. Our crew foremen have decades of experience working on homes throughout the greater St. Louis area, and we document everything with photos so you can see exactly what we see. If repairs are needed, we’ll give you an honest assessment of the scope of work—no upselling, no scare tactics. That’s been our approach for over 19 years.

You should schedule a professional inspection if:

Your roof is more than 15 years old
You experienced a major storm event this past winter (hail, heavy ice, or high winds)
You can see visible damage from the ground, even if it looks minor
You notice any signs of water intrusion in your attic or on interior ceilings
Your energy bills spiked unexpectedly over the winter, which can indicate insulation or ventilation problems related to roof damage
Neighbors in your area are getting roof work done—storm damage tends to affect entire neighborhoods, not just individual homes

Storm Damage and Insurance Claims: What St. Louis Homeowners Should Know

If your spring inspection reveals damage that you suspect was caused by a winter storm, you may be eligible to file an insurance claim. Most standard homeowners’ insurance policies in Missouri cover storm damage, including damage from wind, hail, and the weight of ice or snow.

Family First Exteriors has extensive experience helping St. Louis homeowners navigate the insurance claims process. We can meet with your adjuster on-site, document the damage thoroughly, and make sure nothing gets overlooked. Our goal is to make sure your home is restored properly—not to push unnecessary work through your policy.

Don’t Wait for the Leak to Find You

Here’s the thing about roof damage: by the time you notice a water stain on your ceiling, the underlying problem has usually been developing for weeks or months. Water travels along roof deck panels, rafters, and even electrical wiring before it finally shows up as a visible stain—often far from the actual point of entry. A proactive spring inspection can catch problems while they’re still small and relatively inexpensive to fix.

At Family First Exteriors, we’re a family-owned business that puts families first. We offer a 20% discount to veterans, and we provide financing options to help make necessary repairs fit your budget.
