Why Freeze–Thaw Cycles Are Hard on Cottages
When temperatures rise above freezing, snow and ice melt. When they drop again, that water refreezes—expanding into cracks, seams, and weak points. Over time, this cycle can:
Widen small foundation cracks
Force water under shingles or flashing
Stress plumbing lines
Create ice dams that push water back into the roof system
Cottages are especially vulnerable because many sit on exposed terrain, have long driveways, and may not be checked weekly.
1. Roof & Ice Dam Inspection
Ice dams form when melting snow refreezes along roof edges. Once established, water can back up under shingles and enter the attic or wall cavities.
What to look for:
Thick ice buildup along eaves
Icicles forming repeatedly in the same areas
Uneven snow melt patterns on the roof
Interior signs like ceiling stains or musty odours
Why it matters:
Roof leaks caused by ice dams often stay hidden until spring—by then, insulation and drywall may already be compromised.
2. Foundation & Structural Stress Points
Freeze–thaw cycles cause soil to expand and contract, putting pressure on foundation walls and footings.
Inspection focus areas:
Visible foundation cracks or changes to existing cracks
Shifting stairs or decks pulling away from the structure
Crawl spaces showing signs of moisture intrusion
Ice buildup around the base of the foundation
Pro tip:
Catching foundation movement early can prevent costly structural repairs later.
3. Plumbing & Water Line Safety
Even winterized cottages can be at risk—especially if temperatures fluctuate rapidly or if insulation has shifted.
Check for:
Signs of leaks in basements or crawl spaces
Frozen or bulging exposed pipes
Unusual humidity or condensation
Water stains near plumbing runs
A small plumbing failure in winter can quickly turn into a major issue if no one is there to catch it.
4. Power Outage Red Flags
Mid-winter power outages are common in cottage country. When power is lost, heat systems stop and pipes become vulnerable.
What should be verified:
Backup heat sources functioning correctly
Generators (if installed) are accessible and operational
No tripped breakers or system faults
No evidence of previous freeze damage caused by outages
Even a short outage during a cold snap can cause damage that isn’t immediately obvious.
5. Snow Load on Decks, Roofs & Outbuildings
Snow gets heavier as it melts and refreezes. Decks, sheds, boathouses, and sunrooms often aren’t built to handle extreme loads.
Watch for:
Sagging decks or railings
Bowed rooflines on sheds or bunkies
Doors or windows that suddenly stick
Structural creaking during warm spells
Removing excess snow at the right time can prevent collapse or long-term warping.
6. Exterior Access & Safety
A mid-winter visit isn’t just about damage—it’s about access.
Inspect:
Driveways and emergency access routes
Ice buildup near entrances
Downspouts blocked by ice
Snow drifting against siding or vents
Keeping access clear ensures emergency services—or maintenance crews—can reach the property if needed.
When to Schedule a Professional Mid-Winter Cottage Check
You should strongly consider a professional inspection if:
Your cottage has been unattended for several weeks
There has been a recent freeze–thaw cycle or rain event
The property relies on electric heat
You noticed ice buildup or power interruptions
You won’t be visiting again until spring
A proactive inspection can catch small, manageable issues before they become major repairs.
Peace of Mind Through Winter
Owning a cottage should be enjoyable—not stressful. Mid-winter inspections provide peace of mind by ensuring your property is safe, secure, and weathering winter as it should.
