# How to Prepare Your Roof for a Wisconsin Winter
As the crisp autumn air settles over Northeast Wisconsin, homeowners know that the inevitable snow and ice are not far behind. A Door County winter is beautiful, but it is also one of the harshest environments for a residential roof.
The combination of heavy snow loads, freezing temperatures, and the freeze-thaw cycles that create damaging ice dams can quickly turn a minor roofing issue into a major, costly repair. As a local roofing contractor with over 18 years of experience, **The Roofing Company** has seen exactly what happens when winter preparation is neglected.
Before the first major snowfall blankets Sturgeon Bay, Algoma, or Kewaunee, taking a proactive approach to roof maintenance is essential. Here is our comprehensive guide on how to prepare your roof for a Wisconsin winter.
## 1. Schedule a Professional Fall Inspection
The absolute best way to prepare your roof for winter is to have it inspected by a licensed, insured roofing professional in the fall.
While you can spot some issues from the ground, a professional roofer knows exactly what to look for up close. They will check for:
* **Missing, cracked, or curling shingles** that need replacement before snow and ice can exploit them.
* **Damaged or missing flashing** around chimneys, vents, and valleys—the most common areas for winter leaks.
* **Soft spots in the roof decking** that could collapse under the weight of a heavy snow load.
* **Deteriorating sealant** around roof penetrations that needs to be reapplied.
Addressing these issues in October or November is significantly cheaper and easier than trying to patch a leak during a January blizzard.
## 2. Clean Your Gutters and Downspouts
Your gutters are the unsung heroes of your roofing system. Their job is to direct water away from your roof and foundation. If they are clogged with autumn leaves, pine needles, and debris, water has nowhere to go.
When the temperature drops, that trapped water freezes, creating a solid block of ice in your gutters. This is the primary catalyst for **ice dams**—thick ridges of solid ice that build up along the eaves of your roof. Ice dams prevent melting snow from draining off the roof. The water backs up behind the dam, seeps under your shingles, and leaks directly into your home, causing massive interior water damage.
Clean your gutters thoroughly after the majority of the leaves have fallen, and ensure your downspouts are clear and directing water at least five feet away from your foundation.
## 3. Trim Overhanging Tree Branches
Heavy snow and ice accumulation can cause tree branches to snap. If a large branch is overhanging your roof, it poses a significant threat during a winter storm. A falling branch can easily puncture your roof decking, tear off shingles, or damage your gutters.
Additionally, branches that constantly rub against your roof in the winter wind will scrape the protective granules off your asphalt shingles, drastically reducing their lifespan. Trim any branches that are within six feet of your roofline before the snow flies.
## 4. Check Your Attic Insulation and Ventilation
A healthy roof requires a healthy attic. The temperature in your attic should be as close to the outside temperature as possible during the winter.
If your attic is poorly insulated, heat from your living space escapes into the attic and warms the underside of the roof deck. This causes the snow on your roof to melt, run down to the cold eaves, and refreeze—the exact process that forms destructive ice dams.
Proper attic ventilation (intake vents at the soffits and exhaust vents at the ridge) ensures that cold air constantly circulates, keeping the roof deck cold and preventing snow from melting prematurely. Have a professional check your insulation levels and ensure your soffit vents are not blocked by insulation.
## 5. Be Prepared for Snow Removal
While most roofs in Wisconsin are built to handle significant snow loads, an exceptionally heavy, wet snowfall (often called “heart attack snow”) can exceed the structural capacity of older homes or flat roofs.
If you anticipate needing to remove snow from your roof this winter, invest in a long-handled roof rake. Use it to pull snow off the lower edges of the roof while standing safely on the ground. Never climb onto a snowy, icy roof yourself. If the accumulation is severe, hire a professional snow removal service.
