What’s Causing It, What to Do First, and Why Calling PuroClean Early Matters
If you’re dealing with water stains, bubbling paint, or active leaking during winter in Dover, New Hampshire, the damage is likely already underway.
Ice dams and cold-related pipe failures are among the leading causes of winter water damage in Dover and across Strafford County, especially in apartments, multi-unit buildings, and older homes. These issues often begin out of sight, behind walls, ceilings, or rooflines and escalate quickly once water is released.
Knowing what’s happening, what to do first, and who to call next can significantly reduce damage, downtime, and long-term repair costs.
The Most Common Signs of Winter Water Damage

Winter water damage doesn’t always announce itself right away. Some of the most common signs we see during peak winter season include:
- Water stains on ceilings or upper walls
- Bubbling, cracking, or peeling paint
- Dripping during daytime thaws
- Musty odors near exterior walls or ceilings
- Wet insulation discovered after drywall opens
- Sudden ceiling or drywall collapse
If these signs appear during freezing or thawing conditions, winter-related water damage should be addressed immediately.
Icicles vs. Ice Dams: Why the Difference Matters

Icicles and ice dams are often confused — but they signal very different levels of risk.
Icicles form when melting snow refreezes as it drips off the roof edge. They indicate melting is occurring, often due to heat loss, but they don’t automatically mean water is entering the building.
Ice dams form when repeated melting and refreezing creates a horizontal ridge of ice along the roof edge. Once that ridge blocks drainage, water is forced back under shingles and into wall and ceiling cavities.
At that point, water intrusion is no longer a possibility, it’s actively happening.
Not All Winter Water Damage Comes From the Roof
While ice dams are a major cause of winter water damage, they’re not the only one.
Freezing temperatures can also cause sudden pipe failures behind walls and ceilings, particularly in exterior wall cavities, garages, and poorly insulated areas. When a pipe freezes and fails, water can be released rapidly, causing immediate and visible interior damage.
In many winter losses we respond to, the source isn’t discovered until ceilings open or drywall fails.
Why Apartments and Multi-Unit Buildings in Dover Are Higher Risk
Dover’s housing stock includes many older apartment buildings and multi-unit properties that face elevated winter risk due to:
- Shared attic spaces with uneven insulation
- Multiple heat sources beneath one roof
- Deferred winter maintenance
- Limited visibility of early warning signs
- Water traveling between units before it’s noticed
For property managers and tenants alike, early reporting and proper sequencing are critical to limiting damage and protecting the building.
What to Do If You Have Winter Water Damage Right Now
When winter water damage occurs, the order of response matters — both structurally and from an insurance standpoint.
Step 1: Stop the source of the water
Ice dams must be addressed by qualified roofing professionals. Frozen or burst pipes require a licensed plumber.
