Winter can be tough on your home, especially your roof. In areas like Buffalo, Rochester, Syracuse, Albany, and throughout upstate New York, heavy snowfall, lake‑effect snow, and frequent freeze‑thaw cycles make ice dams a common roofing problem for homeowners. One of the most common (and costly) cold‑weather issues homeowners face is ice dams. While they may look harmless at first, ice dams can lead to serious roof damage, leaks, and even interior water damage if left unaddressed.
Below, we’ll explain what ice dams are, why they form, how they can damage your roof, what you can do to prevent them, and when it’s time to call in a professional.
What Are Ice Dams on a Roof?
An ice dam is a ridge of ice that forms along the edge of a roof, typically near the gutters. As snow melts and refreezes, this ice buildup blocks proper drainage. When melting snow can’t flow off the roof, water can back up underneath shingles and seep into your home.
Ice dams are most common after heavy snowfall followed by fluctuating temperatures—especially when daytime melting is followed by overnight freezing.
Why Do Ice Dams Form in Western and Upstate New York?
Ice dams usually form because of uneven roof temperatures. Here’s how that happens:
- Heat escapes from the home into the attic
- That heat warms the roof surface, causing snow to melt
- Melted snow flows down toward the colder roof edge
- The water refreezes at the eaves, creating a dam of ice
Several factors can contribute to this process, including:
- Insufficient attic insulation
- Poor attic ventilation
- Air leaks from living spaces into the attic
- Clogged or damaged gutters
How Ice Dams Damage Roofs in Buffalo, Rochester & Across Upstate NY
Ice dams aren’t just a nuisance; they can cause real damage. When water backs up behind an ice dam, it can:
- Leak under shingles, bypassing your roof’s protective layers
- Damage roof decking and underlayment
- Cause interior water stains on ceilings and walls
- Lead to mold and mildew growth
- Warp or rot fascia boards and soffits
- Pull gutters away from the home due to added weight
Over time, repeated ice dam issues can shorten the lifespan of your roof and lead to costly repairs.
How to Prevent Ice Dams in Western and Upstate New York Homes
While some ice dam prevention requires professional solutions, homeowners can take a few proactive steps:
- Safely remove excess snow from the roof using a roof rake after heavy snowfall
- Keep gutters clear so melting snow can drain properly
- Seal obvious air leaks around attic hatches, vents, and recessed lighting
- Maintain consistent indoor temperatures during extreme cold
It’s important to avoid chipping ice directly off the roof, which can damage shingles and create safety hazards.
When to Call a Roofing Professional for Ice Dams
You should contact a professional if:
- You notice water stains or leaks inside your home during winter
- Ice dams keep returning year after year
- Shingles appear loose, lifted, or damaged
- Gutters or fascia are pulling away from the roofline
- You suspect underlying insulation or ventilation issues
A professional inspection can identify both visible damage and hidden problem areas before they get worse.

Over time, ice dams can lift, loosen, or crack shingles and damage the roof underlayment, reducing the overall lifespan of your roof.

Minor snow removal with a roof rake can help, but physically removing ice dams can be dangerous and may damage your roof. Persistent or severe ice dams should be addressed by a professional.
