If you’ve weathered even a single winter here in southeastern PA, you know it’s true. It’s a season that loves to keep us guessing.
One week, it’s beautiful fluffy snow, the next, a brutal icy rain, and then somewhere in between, everything melts into that familiar holiday slush (that loves to refreeze).
But while the weather may be unpredictable, expensive roofing and siding damage doesn’t have to be. In fact, a bit of seasonal prep, paired with a quick check of your home’s exterior, can make the cold months far easier on both your home and your wallet.
With that in mind, the Smucker crews put together this helpful guide for Pennsylvania homeowners. Give it a scan to learn how the upcoming cold season puts homes at risk, plus the simple tips for keeping your property in great shape year-round.
And with that, let’s dive in.
Why Do PA Winters Wreak Havoc on Roofing Systems?
The truth is, winters here in Pennsylvania are tough on roofs. This has to do with the state's constant freeze-thaw cycles. When liquids freeze, melt, and then refreeze, shingles, flashing, and underlayment take a beating. Normally, moisture runs off the roof, and this is not an issue.
The problem is that rooftop snow taps water and moisture under it, which melts during the day and refreezes at night—allowing expanding water to work its way into the tiny gaps between shingles. Over time, the pressure can be enough to loosen shingles and weaken seals—creating additional entry points for unwanted moisture.
What Are Ice Dams—and Why Are They Troubling to Homeowners?
When the heat inside your home escapes into the attic and warms the roof, snow melts prematurely. This melted snow then runs down toward the eaves and refreezes into a ridge of ice at the edge of your roof—creating a dam that prevents further meltwater from draining.
These “dams of ice” push meltwater back underneath the shingles. And left unchecked, ice dams can lead to all sorts of problems.
For example:
- Ceiling leaks and stains
- Peeling interior paint
- Soggy, ineffective insulation
- Hidden rot behind walls
- And even framing issues
The best prevention of ice dams is proper roofing installation and balanced attic ventilation. Because, while it may seem counterintuitive, a cooler attic temperature is preferable in the winter. (Just don’t spend too much time up there.)
How Do I Check for Early Signs of Potential Roof Damage?
Smucker Exteriors recommends all of our homeowners do a quick fall inspection of their roofs before the freezing temperatures come.
Here are some things to look out for:
- A roof nearing its 20-year lifespan
- Missing, loose, or curling shingles
- Gutters sagging or pulling away from fascia
- Stains or watermarks on interior ceilings or walls
- Balding shingles with granules washed into gutters
Many of these issues can be quickly remedied with a short visit from a reputable roofer. However, don’t wait—because these smaller issues only ever get worse… especially once the ice rolls around.
What if I Have Vinyl Siding?
While roofs tend to get the most attention, siding faces its own winter challenges—especially vinyl.
Fluctuating temperatures cause vinyl to expand and contract. Over time, this leads to brittle panels that are more prone to cracking.
Additionally, freezing rain and strong winds can loosen siding panels, letting moisture seep in behind them. Once water gets in, it can then freeze and push siding further out—creating breeding grounds for mold and rot when temperatures warm.
Here are some common signs your siding needs repaired:
- Bulging or bubbling spots
- Visible cracks or open seams
- Loose, warped, or missing panels
- Persistent mold or mildew in shady areas
- Soft, spongy areas you can press in (get repaired ASAP)
While these inspections can certainly be done by the homeowners themselves, a quick seasonal check from a siding professional is never a bad idea.
How Can I Prepare My Roof for Winter?
While freeze-thaw cycles and ice dams are an expected part of winter, just a few simple chores this fall can radically reduce your chances of roofing trouble during a cold snap.
- Clean Your Gutters: Leaves and debris trap water that freezes into ice dams, so be sure to clear your gutters and downspouts—or better yet, install gutter guards
- Trim Back Overhang: Heavy snows can snap branches—and all it takes is one loud “crack” to puncture an otherwise sound roof
- Check Attic Insulation/Ventilation: A balanced attic temperature prevents the roof from warming unevenly, reducing the risk of ice dams and unwanted water intrusion
While these tasks are manageable for many homeowners, ladders aren’t everyone’s thing—so you may be better off calling a friendly exterior contractor in your area.
How Do I Know If I Need A Professional Inspection?
Often, homeowners wonder whether winter inspections are worthwhile—or even possible this time of year.
The short answer is: yes.
In fact, a winter inspection may be necessary. Especially if you’re noticing…
- Stains or moisture inside
- Wind damage after a storm
- Rattling, bulging, or lifting siding
- Icicles or ice ridges along your roofline
Roofing and siding experts can often diagnose issues even with snow present. And in many cases, temporary winter repairs can be completed immediately—with permanent remediations scheduled for early spring.
Can I Get Exterior Repairs During the Winter?
Most homeowners assume winter is a terrible time for exterior repairs. And, to be fair, it isn’t ideal. However…
Modern roofing and siding materials make winter service more feasible than ever. Many repairs—even certain full replacements—can be safely completed in cold weather. It all depends on the outdoor temperature and material types.
This is to say you have nothing to lose by calling a reputable exterior contractor in your area at any time—especially if you’re noticing any of the more serious signs of exterior wear.
Things like:
- Active leaking in your home
- Shingles or flashing pulled loose
- Ice dams are creating visible damage
- Missing siding panels or exposed insulation
In other words, water damage doesn’t wait for warmer weather—and neither should you.
