When to Prevent Ice Dams in Edina, MN

ON TRACK127 days until snow season (estimated)Nov 15

In Edina, snow starts holding on the roof near November 15 (roughly 51" falls yearly), and that's when ice dams form at the cold eaves, so do the attic work first. The early-to-late range spans roughly 27 days, so treat the median as a midpoint, not a promise.

NOAA station: Minneapolis/St Paul AP · 5.9 mi away · 872 ft elevation.

Numbers for Edina come from Minneapolis/St Paul AP, 5.9 miles away at 872 feet, where the medians fall 32°F by Oct 18, 28°F by Oct 29, 24°F by Nov 6. Year to year the 28°F date has ranged from Oct 15 to Nov 11 — about 27 days apart. Spring's last 32°F freeze clears around Apr 23. Snowfall averages 51 inches a year, first reaching an inch near November.

Edina usually sees its first 32°F night about Oct 18, with the first 28°F hard freeze close behind near Oct 29. The 32°F date swings from Oct 1 at its earliest to Oct 31 at its latest, near 30 days. The last spring freeze averages Apr 23 and as late as May 7, which sets the safe window for reopening outdoor water and de-winterizing gear. Roughly 51 inches of snow fall in an average year, so a clear roof edge and a running snow blower matter as much as the freeze itself.

Your ice dams checklist

  1. Before snow flies, seal attic air leaks around lights, the attic hatch, and plumbing stacks so warm air stays out of the attic.
  2. Add insulation to bring the attic floor up to a deep, even blanket; a cold roof deck is what stops dams from forming.
    Helpful gear: Attic vent bafflesRecommended pick
  3. Confirm soffit and ridge vents are open and clear so outside air keeps the underside of the roof cold.
  4. After a storm drops four inches or more, rake the lower three to six feet of roof from the ground.
    Helpful gear: 21-foot roof rakeRecommended pick
  5. Keep a safe distance from the edge while raking and never climb an icy roof; work from the ground.
  6. If a dam forms, lay a calcium-chloride melt sock across it to open a drainage channel — do not chip at the ice.
    Helpful gear: Calcium chloride roof-melt socksRecommended pick
  7. For a roof that dams every year, have heat cable installed at the eaves before the season starts.
    Helpful gear: Roof de-icing heat cableRecommended pick
  8. Watch for long icicles and interior ceiling stains; both are early signs water is backing up under the shingles.

Ice dam removal cost & key numbers

Verified national benchmarks; sources open in a new tab (nofollow).

$300–$700/hr

Professional steam removal rate, with typical jobs totaling $650–$2,400. Steaming is the shingle-safe method — chipping and rock salt destroy roofs.

Angi
R-49 to R-60

Attic insulation DOE and ENERGY STAR recommend for most US climate zones. Air-seal ceiling penetrations first — insulation alone will not stop ice dams.

ENERGY STAR
3–4 ft

How far up from the eaves to clear snow with a roof rake after each storm — it removes the meltwater source in the ice-dam zone. A telescoping rake costs $30–$100.

Travelers
$3,000–$15,000

Typical interior repair bill once an ice dam pushes water into the attic and walls — wet insulation, saturated drywall, and mold remediation if drying is delayed.

What this means locally

Edina freezes close to Bloomington (Nov 15) and close to St. Louis Park (Nov 15) — a reminder that even nearby towns differ by days. Statewide, Minnesota prep dates run Sep 15 through Oct 16, which is why Edina gets its own number rather than a Minnesota-wide average. The same freeze also decides when to guard your pipes and ready your snow blower. Keeping an eye on the rest of the county? The same local math is on our Eden Prairie and Lakeville pages.

Frequently asked questions

What causes ice dams?
Heat escaping into the attic warms the roof deck and melts the underside of the snowpack. That meltwater runs down to the cold eave, where it refreezes into a ridge of ice. The dam then traps later melt, which can back up under the shingles. University Extension programs point to attic heat loss as the root cause.
How much snow on a roof causes ice dams?
There is no single number, but several inches of snow that lingers gives dams the material they need, especially when days rise above freezing and nights fall below. A roof that sheds snow quickly or stays uniformly cold rarely dams. Watch for snow that sticks around through a stretch of thaw-freeze weather.
Do heat cables prevent ice dams?
Heat cables do not fix the underlying attic-heat problem, but installed in a zig-zag at the eaves they can keep a melt path open so water drains instead of pooling. They work best as one part of a plan that also includes air sealing, insulation, and ventilation. Run them only when needed to save energy.
Is roof raking worth it?
Removing the lower three to six feet of snow from the ground after a storm takes away the material a dam forms from, and it is one of the safest do-it-yourself steps. Use a roof rake with an extension and keep clear of the edge. Never climb onto an icy roof to rake.
Will my insurance cover ice dam damage?
Many homeowner policies cover sudden interior water damage from an ice dam, but coverage and deductibles vary, and repeated damage may raise questions about maintenance. Document the damage with photos. Preventing dams through attic work is cheaper and less disruptive than filing repeat claims.
How do I know if I have an ice dam forming?
Look for a thick ridge of ice at the eaves, large icicles hanging from the gutters, and water stains on interior ceilings or the tops of exterior walls. Icicles alone are not proof, but combined with a warm attic and lingering roof snow they are a warning worth acting on.
How do I remove an ice dam without wrecking the roof?
The shingle-safe professional method is low-pressure steaming at $300–$700 per hour. From the ground you can rake snow off the first 3–4 feet above the eaves and lay a calcium-chloride-filled sock across the dam to melt a drainage channel. Never chip ice with hatchets or use rock salt — both destroy shingles, flashing and gutters.
