Winter in Des Moines, Iowa, is no joke. With heavy snowfall, ice storms, and freezing temperatures, your home’s exterior—especially the siding and roof—bears the brunt of the season. At Superior Siding and Window Systems, we’ve seen it all: cracked siding from fluctuating temperatures, ice dams wreaking havoc on roofs, and wind storms tearing shingles right off. Preparing your home now can save you stress, money, and headaches later.
In this guide, we’ll walk you through how to prepare your siding and roofing for the harsh Des Moines winter, provide examples of past winter weather that caused significant damage, and share tips on how to react if damage does occur.
Why Winter Preparation Matters in Des Moines
Central Iowa winters are notorious for their unpredictability. In 2020, a massive winter storm brought over 10 inches of snow to Des Moines, and in 2007, a severe ice storm left thousands without power and caused significant damage to homes. Events like these remind us how important it is to fortify our homes against the elements.
Without proper preparation, your siding could crack or warp, allowing moisture to seep into your home. Similarly, your roof could suffer from ice dams or wind damage, leading to costly repairs. Let’s ensure your home is ready for whatever winter throws at it.
Preparing Your Siding for Winter
1. Inspect for Damage
Before temperatures drop, take a close look at your siding. Are there any cracks, gaps, or warping? Small issues now can become big problems when freezing temperatures hit. For example, worn or damaged vinyl siding is prone to cracking during Iowa’s freeze-thaw cycles. Fixing these issues early helps keep cold air and moisture out.
2. Clean Your Siding
Dirt, mold, and mildew can trap moisture, which freezes and expands in winter. Use a power washer or a soft scrub brush to clean your siding thoroughly. Be sure to remove leaves and debris stuck in the crevices. This step not only protects your siding but also enhances your curb appeal.
3. Seal Gaps and Cracks
Caulking around windows, doors, and joints is crucial. Moisture can seep through tiny cracks and freeze, causing even more damage. Look for old, peeling caulk and replace it with a high-quality, weather-resistant sealant.
4. Repaint or Treat Wood Siding
For homes with wood siding, a fresh coat of paint or stain adds an extra layer of protection against moisture and cold air. Wood is especially susceptible to rot during wet, freezing winters, so this step is essential.
Preparing Your Roof for Winter
1. Inspect Shingles and Flashing
Take a walk around your home and look up at your roof. Are there any missing or damaged shingles? How about loose flashing around chimneys, vents, or skylights? Replace and secure these elements before the first snowfall.
2. Clean Gutters and Downspouts
In Iowa’s winters, clogged gutters can lead to ice dams—a homeowner’s nightmare. When gutters can’t drain properly, melting snow refreezes at the edge of the roof, causing water to back up under the shingles. Clean your gutters thoroughly and ensure downspouts direct water away from your foundation.
3. Trim Nearby Trees
Overhanging branches can become dangerous when heavy with snow or ice. Trim them back to avoid damage to your roof or siding during a storm.
4. Check Your Attic Insulation and Ventilation
Adequate attic insulation helps regulate the temperature of your roof, preventing uneven snowmelt and ice dams. Proper ventilation, meanwhile, reduces moisture buildup that can lead to mold.
Des Moines’ Winter Challenges: Real-Life Examples
- The Ice Storm of 2007
Homes across Des Moines were covered in sheets of ice, leading to widespread damage to roofs and siding. Many homeowners faced cracked vinyl siding and water infiltration. Those who had properly caulked and sealed their exteriors fared much better. - 2021 Polar Vortex
When temperatures plummeted below zero for several days, many homes experienced burst siding panels and shingle blow-offs. This was a wake-up call for residents to inspect and reinforce their home exteriors annually.
How to React When Winter Damage Happens
Sometimes, no amount of preparation can prevent damage from severe weather. Here’s how to handle common winter issues:
- Ice Dams: If water is leaking into your home, remove snow from the roof edge with a roof rake (if safe to do so). Call a professional to remove the ice dam and inspect for damage.
- Cracked Siding: Cover the area with a weatherproof tarp to prevent further moisture infiltration. Contact Superior for a repair assessment.
- Roof Leaks: Place a bucket to catch drips and minimize interior damage. Avoid climbing on the roof in icy conditions—call an expert instead.
