Winters in Minnesota and Wisconsin are tough on homes. Deep snow, repeated freeze–thaw cycles, and below-zero temps turn minor roof vulnerabilities into ice dams, leaks, stained ceilings, and damaged insulation. Ice dams aren't just ugly—they can cause serious water intrusion, mold, and structural issues if they're not handled correctly.
Advanced Roofing & Siding helps homeowners, HOAs, and light commercial property owners across Minnesota and Western Wisconsin navigate ice dam and snow damage insurance claims from first drip to final check:
- 24/7 winter damage response
- Roof, attic, and interior inspections
- Documentation tailored for adjusters
- Code-based repair scopes for Minnesota & Wisconsin
- Full roof and exterior replacement when warranted—not just cosmetic fixes
Our goal is simple: stop the leak, document the loss, maximize what your policy owes you, and rebuild your home or building to code.
What Is an Ice Dam (and Why It's an Insurance Problem)?
Understanding how ice dams form and why they cause damage
An ice dam forms when heat from your home melts snow on the roof, the meltwater runs down to the cold eaves, and then refreezes at the edge. Over time, this creates a thick ridge of ice that traps water behind it. That standing water can back up under shingles and leak inside, damaging ceilings, walls, insulation, and sometimes flooring and cabinets.
Common contributing factors:
- Warm, leaky ceilings and poor air sealing
- Inadequate attic insulation or uneven insulation levels
- Poor attic ventilation (hot attic, cold eaves)
- Complex roof designs, skylights, and recessed lights in the ceiling
From an insurance perspective, what matters is the resulting water damage and whether it was sudden, accidental, and properly mitigated—not whether your attic was perfectly insulated beforehand.
Typical Ice Dam & Snow Damage We See
Ice dams and heavy snow can create several layers of damage
Exterior & Roof
- Water-backed up under shingles and into the roof deck
- Saturated or rotted sheathing along the eaves
- Damaged underlayment and ice & water barrier
- Broken gutters, downspouts, and fascia from ice weight
- Loosened soffit panels and trim
Interior
- Water stains on ceilings and walls
- Peeling paint, cracked drywall, or bubbling texture
- Wet insulation in the attic or wall cavities
- Mold or mildew growth if not dried quickly
- Damaged built-ins, flooring, or trim near exterior walls
Does Homeowners Insurance Cover Ice Dams & Snow Damage?
Understanding what's covered and what's not
Usually Covered (when sudden & accidental)
- Water stains and damaged drywall/paint from ice dam leaks
- Damaged insulation, flooring, or cabinets caused by water intrusion
- Tear-out and replacement of building materials necessary to access and repair the leak
- Roof repairs/replacement where water has penetrated and materials are compromised
Often Not Covered
- Fixing the underlying cause of the ice dam (upgrading attic insulation)
- Improving ventilation or air sealing
- Long-term energy-efficiency improvements
- Damage due to ongoing neglect (e.g., long-term leaks left unaddressed)
Both Minnesota's Department of Commerce and Wisconsin's insurance regulator advise homeowners to notify their insurer promptly after winter damage and to document everything—photos, dates, and mitigation steps. Advanced Roofing & Siding helps you organize this documentation in a way adjusters understand.
How Minnesota & Wisconsin Building Codes Treat Ice Dams
Both states have building code requirements designed to reduce the risk of ice dam leaks
Minnesota Residential Code
Minnesota requires an ice barrier at the eaves of most heated buildings, typically consisting of either:
- At least two layers of underlayment cemented together, or
- A self-adhering polymer-modified bitumen sheet ("ice & water shield")
This barrier must extend from the roof edge to a point no less than 24 inches inside the exterior wall line (often resulting in 6 feet of ice & water shield along eaves).
Wisconsin Uniform Dwelling Code
Wisconsin's code similarly requires ice dam protection at eaves:
Ice dam protection must extend at least 30 inches up the roof slope from the roof edge and at least 12 inches beyond the interior wall line.
Many municipalities require ice & water barrier to extend from the eaves up 2 feet past the warm wall, and some low-slope roofs may require extended coverage.
When we review an insurance scope, we don't just look at "how many shingles." We check that your insurer's estimate includes code-required ice barrier, underlayment, and ventilation—and we submit supplements when it doesn't.
Our Ice Dam / Snow Damage Claim Process
From emergency mitigation to full, code-compliant restoration
Winter Damage Assessment & Emergency Mitigation
When you call Advanced Roofing & Siding, we perform a comprehensive inspection and recommend emergency steps.
- Roof and attic inspection where safe and accessible
- Identify active leaks, saturated materials, and high-risk areas
- Recommend emergency steps (tarping, controlled snow removal)
- Advise on what to photograph and save
- Act quickly to prevent further damage
Documentation for Your Ice Dam Insurance Claim
We create an evidence package tailored for adjusters that makes it easy to see the full picture.
- Date-stamped photos of exterior and interior damage
- Roof and attic photos showing water path
- Notes on roof age, construction type, and code deficiencies
- Measurements and diagrams for affected areas
- Clear explanation of how the ice dam formed
Guided Claim Filing with Your Carrier
You remain in control of your policy and claim. We help you navigate the process.
- Help decide if damage rises to claim-worthy level
- Explain how ice dam/snow damage should be described
- Clarify deductible, coverage areas, and exclusions
- Encourage prompt filing and record keeping
- Understand your policy fully
On-Site Adjuster Meeting
When your insurer sends an adjuster, we meet them at the property to ensure nothing is missed.
- Meet adjuster at the property
- Walk through roof/attic and interior damage
- Point out code requirements for ice barriers
- Help distinguish current damage vs. pre-existing
- Ensure fair and full evaluation
Scope Review & Code-Based Supplements
We review the estimate line by line and submit supplements when code requirements are missing.
- Check for proper ice & water barrier coverage
- Verify adequate replacement of damaged decking
- Confirm correct underlayment and ventilation
- Review interior repairs matching real damage
- Submit supplements with code citations
Repair, Replacement & Prevention-Focused Recommendations
After approval, we complete the work and provide preventive recommendations.
- Roof repair or replacement with ice & water barrier
- Replacement of damaged decking, underlayment, shingles
- Interior repairs: drywall, texture, paint, trim, insulation
- Gutter, soffit, and fascia replacement as needed
- Preventive recommendations for long-term protection
Special Considerations for HOAs, Townhomes & Commercial Buildings
Ice dams and snow loads are a major issue on townhomes, rowhouses, and low-slope commercial roofs
We regularly work with HOA boards and property managers, churches and small commercial buildings, and mixed-use and multi-tenant properties.
Key points we help clarify:
- What's covered by the association's master policy vs. individual unit owners (HO-6 policies)
- How to coordinate common-area vs. interior claims
- Snow removal, roof access, and safety during winter mitigation
- Documentation suitable for board meetings and reserve planning
Our role is to simplify the process, protect the building, and keep owners and residents informed.

Ice Dam & Snow Damage Claim FAQ
Common questions about ice dam and snow damage insurance claims
Do I need to remove the ice dam before filing a claim?
No, but you should prevent further damage. That may mean roof snow removal, tarping, or professional ice dam steaming—documenting each step and keeping receipts. Your insurer cares that you mitigated additional loss.
Will insurance pay to fix my attic insulation and ventilation?
Usually not. The resulting damage (ice dam leak, interior water damage) is often covered, but the underlying cause (insulation/ventilation) is typically considered a maintenance or improvement item. Still, we'll clearly separate the covered work from the recommended upgrades.
Is an ice dam considered "flood" damage?
No. Ice dam leaks are generally treated as water damage from above and addressed under homeowners insurance, not flood insurance. Overland flooding and ground water seepage are separate and typically excluded without a flood policy.
How fast should I act after noticing a leak?
Immediately. Both Minnesota and Wisconsin guidance say to contact your insurer right away, mitigate further damage, and keep detailed records.
What if my insurance company underpays or denies my ice dam claim?
You have options: ask for a reinspection, provide additional documentation or contractor supplements, or escalate through your carrier's internal review process. In Wisconsin, you can contact OCI; in Minnesota, the Department of Commerce for help with claim disputes. Advanced Roofing & Siding can help you understand what's missing and what the next step should be.
