Is Your Roof “Unbuttoned”?

As a homeowner in Southwest Montana, you’re used to the wind.

But after a major storm, just because your shingles are still attached doesn’t mean your home is protected.

At Mountain Roofing, our core value is To Care. That means we don’t just look for missing shingles; we look for the integrity of your home’s defense. Often, the wind doesn’t blow shingles off—it simply breaks their thermal seal.

Think of it like unbuttoning your winter coat. You’re still wearing it, but it’s no longer keeping the cold out. Here is how you can inspect your home’s first line of defense after a Montana wind event.

Why Shingle Seals Fail in Southwest Montana

In our region, shingle seals are put to the ultimate test. There are two primary reasons we see seal failure on local roofs:

1. Cold-Weather Installation Issues

In Montana, we often have to roof in cold temperatures. However, asphalt shingles require solar heat (aka those UV rays) to “activate” their adhesive strip. If a roof was installed in the winter and didn’t get enough sun to bond, the shingles remain “loose,” leaving them vulnerable to the very first wind storm. Knowing how often the wind blows, those sealant strips often become coated with dust before they can activate. According to the National Roofing Contractors Association, this means the minimum temperature needs to be 40º and rising (while it is the minimum, it’s not ideal).

2. Age and Extreme Temperature Swings

The extreme temperature fluctuations in our valley causes shingles to expand and contract. Over time, the adhesive becomes brittle. Once the wind gets under a brittle shingle, the seal snaps, and the shingle begins to “chatter.”

Stop the Leak Before It Starts

A broken seal today is a ceiling leak tomorrow. Don’t wait for the rain or snowmelt to find the weak spots. Take ownership of your home’s protection and let Mountain Roofing provide a comprehensive health check for your roof.

Your 5-Point Post-Wind Damage
Roof Checklist

You can perform a preliminary check from the safety of the ground. Grab a pair of binoculars and look for these five warning signs:

Visible from the ground, dark horizontal lines indicate broken seals as a result of wind damage.

The “Shadow” Test

Look at the horizontal lines of your shingles during the morning or evening. Do you see small, dark shadows under the edges? This usually indicates a “lifted” shingle where the seal has failed.

Listen for the “Chatter”

On a breezy day, stand near your eaves. Can you hear a subtle “clapping” or “chattering” sound? That is the sound of loose shingles lifting and hitting the roof deck. It’s a tell-tale sign that your roof is no longer a single, bonded unit.

Asphalt roof shingles that have lost their seals can "chatter" in the wind.
Wind damage presents itself most often on the ridge. Look from the ground for variations in the roof line indicating missing shingles.

Check the “Ridge Caps”

The very peak of your roof takes the brunt of the wind. Check to see if the shingles at the peak look crooked or slightly shifted. If the ridge is compromised, moisture can easily drive underneath.

The Gutter Patrol

Check your downspouts. If you see an unusual amount of granules (the “sand” that coats shingles), it’s often a sign of friction. When seals fail, shingles rub against each other in the wind, shedding their protective coating.

Loose ceramic granules, the protectant coating on asphalt shingles, will gather in the gutters when the roof is failing.
Keep a close eye on areas with flashing like chimneys and dormers. Lifted roof shingles in these areas due to wind damage can allow water to penetrate under the flashing and into your house.

Inspect the Flashing

Check the areas around your chimney or vents. If shingles have shifted even slightly, the metal flashing underneath can become exposed, creating a direct path for leaks during the next snowmelt or rain storm.

Don’t Wait for a Leak to Find Out

A failed seal is an open invitation for water damage. Once the wind “unbuttons” your roof, rain and snow can find their way into your attic, often staying hidden until the damage is extensive and expensive.
