What Parts of Your Roof and Exterior Should You Check Before the First Winter Storm?

By McCoy Roofing

Short Answer: Before the first winter storm, homeowners should check their roof for loose or damaged shingles, inspect visible flashing and roof edges, clear gutters and downspouts, look for siding damage, evaluate window and door seals, and watch for attic moisture or ventilation problems. McCoy recommends identifying potential weak points before snow, ice, and strong winds make exterior problems harder and more dangerous to address.

Winter storms have a way of revealing problems homeowners did not realize were there.

A shingle that was already loose may lift during strong winds. A gutter filled with leaves may struggle to drain melting snow. A small gap around a window may become more noticeable when temperatures drop. And a roof that performed well during summer rain may face a different challenge when snow and ice arrive.

That's why preparing for winter is about more than stocking up on salt and finding the snow shovel.

The National Weather Service is highlighting winter preparedness across the region, with South Dakota Winter Weather Preparedness Day on October 28 and Winter Weather Awareness Day in Nebraska and Iowa on November 5.

These awareness days are good reminders that the best time to identify potential exterior problems is before the first significant winter storm.

Why should homeowners inspect their exterior before winter storms arrive?

Winter weather can expose weaknesses that developed during other seasons.

Throughout the year, roofing and siding endure sun exposure, hail, wind, heavy rain, and changing temperatures. Those conditions may leave behind loose materials, worn seals, weakened flashing, or drainage problems that have not yet caused noticeable damage.

Once snow, ice, and freezing temperatures arrive, those vulnerabilities can become harder to diagnose and repair.

McCoy recommends approaching winter preparation as a way to understand your home's current condition, not as a reason to assume something is wrong. A simple visual inspection may reveal nothing concerning, but it can also identify issues worth addressing while conditions are still favorable.

What should homeowners look for on their roof?

Start with the shingles, particularly around roof edges and areas that have experienced previous storm damage.

From the ground, look for shingles that appear lifted, curled, missing, or uneven compared with the surrounding roofing. Also pay attention to areas around chimneys, vents, skylights, and valleys where different parts of the roofing system meet.

These transition points often rely on flashing and other protective details to help direct water away from vulnerable openings.

McCoy recommends having damaged or questionable roofing evaluated before winter weather arrives. A loose shingle or compromised flashing detail may not cause an immediate leak, but wind-driven snow, ice, and melting water can create conditions that expose the problem.

Homeowners should never climb onto a wet, frosty, snowy, or icy roof to investigate concerns themselves.

Why should gutters and downspouts be checked before snow?

Gutters and downspouts help control where water goes when snow and ice begin to melt.

By late fall, gutters may contain leaves, branches, shingle granules, and other debris. If water cannot drain freely, it may overflow, collect around roof edges, or run down siding and fascia.

When temperatures fall below freezing, trapped water can create additional problems.

McCoy recommends checking gutters for visible debris, sagging sections, loose connections, and evidence that water has been spilling behind or over the gutter. Downspouts should also direct water away from the foundation rather than allowing it to collect beside the home.

Clearing drainage problems before winter is generally much easier than addressing them after gutters have filled with ice.

Can attic ventilation affect how a roof handles winter weather?

Yes. Attic conditions can influence roof temperatures, moisture, and the potential for ice dams.

During winter, warm air escaping from the living space into the attic can contribute to uneven roof temperatures. When snow melts on warmer portions of the roof and refreezes near colder roof edges, ice dams may form.

These ice barriers can prevent melting snow from draining normally, potentially allowing water to back up beneath roofing materials.

ENERGY STAR explains that natural attic ventilation helps keep the roof deck colder during winter, while proper insulation and air sealing limit the movement of heat and moisture from the home into the attic.

McCoy recommends watching for recurring ice buildup, unusual moisture in the attic, and signs that soffit vents may be blocked. Ventilation, insulation, and air sealing work together, so correcting one issue may require looking at the entire attic system.

What siding problems should homeowners address before winter?

Siding is another important part of the home's protection against wind and moisture.

Strong winter winds can put additional pressure on siding panels that are already loose or damaged. Snow and melting ice can also expose gaps around trim, corners, windows, and doors.

Walk around the home and look for siding that is cracked, warped, detached, or no longer sitting securely. Pay particular attention to areas where different exterior materials meet.

McCoy recommends taking visible gaps and repeated moisture staining seriously. Siding is designed to shed water, but the wall system behind it must also manage moisture properly.

Loose siding does not automatically mean the entire exterior needs replacement. It may be an isolated repair, but understanding the extent of the problem before winter is important.

Why do window and door seals matter during winter storms?

Windows and doors can allow unwanted air movement when weatherstripping, caulking, or other sealing components begin to fail.

Cold winds may make these problems easier to notice, especially in rooms that already feel draftier than the rest of the home.

ENERGY STAR notes that air leaking through a home's exterior envelope, including windows and doors, can waste energy and reduce comfort.

McCoy recommends checking for cracked caulking, worn weatherstripping, visible daylight around doors, soft trim, and moisture stains near window frames.

Not every draft requires a new window or door. Some problems can be addressed through maintenance or sealing, while others may indicate a deteriorating frame or larger installation issue.

The important thing is determining where the problem actually begins.

Does a warmer winter outlook mean homeowners can worry less about storms?

Not necessarily.

Seasonal weather outlooks describe broad temperature and precipitation patterns over several months. They do not predict every individual storm or guarantee that a particular community will avoid snow, ice, or strong winds.

A warmer-than-average winter can still include significant winter storms, freezing rain, and sudden temperature changes.

For Midwest homeowners, the practical takeaway is simple: prepare for the weather your home may experience, not just the seasonal average.

A roof still needs to shed water, resist wind, and handle changing temperatures whether the winter turns out warmer or colder than usual.

How can homeowners safely inspect their exterior before winter?

A useful exterior inspection does not require climbing a ladder or walking on the roof.

Start by walking around the home on a clear day. Look at the roofline, siding, gutters, windows, doors, and visible trim. Use binoculars or a camera with zoom to examine areas that are difficult to see from the ground.

Check the yard for roofing materials or debris left behind by previous storms. Look for staining around roof edges, loose siding near corners, and downspouts that appear disconnected or damaged.

Inside, pay attention to ceiling stains, damp insulation, condensation, and rooms that feel unusually drafty.

If something looks concerning, take photos and contact a qualified professional rather than attempting an unsafe inspection.

McCoy recommends making safety the priority. No maintenance concern is worth risking a fall, particularly once frost, snow, or ice is present.

When should homeowners schedule a professional inspection?

A professional inspection is worth considering when there is visible damage, a history of leaks, repeated ice buildup, unexplained interior moisture, or roofing and siding that may have been affected by previous storms.

It can also be useful when homeowners are unsure whether an exterior issue is cosmetic or requires attention before winter.

Not every concern requires a major repair or replacement. A professional evaluation can help identify what needs to be addressed now, what can be monitored, and what may require longer-term planning.

The first winter storm may be weeks away, but preparation does not need to wait for the forecast.

Take a closer look at the parts of your home responsible for keeping wind, water, snow, and ice outside. If something looks loose, damaged, or out of place, address the question before winter weather makes the answer harder to find.

The goal is not to predict the next winter storm. It's to make sure your home is prepared when it arrives.
