Can Melting Snow Damage My Roof?

Winter weather brings snow, ice, and freezing temperatures—but many homeowners don’t realize that melting snow can be just as damaging to your roof as the snow itself. As temperatures rise and fall, melting and refreezing can create serious issues that may lead to leaks, structural damage, and costly repairs.

At Mills Roofing, we help homeowners understand how winter conditions affect their roofs and what to watch for before problems worsen.

How Melting Snow Can Damage Your Roof

1. Ice Dams

One of the most common winter roofing problems caused by melting snow is ice dams. These form when heat from your home melts snow on the roof, causing water to run down and refreeze near the eaves.

Over time, ice dams:

• Block proper drainage

• Force water back under shingles

• Lead to leaks inside your home

• Cause damage to shingles, fascia, and gutters

• 
  

2. Water Seepage Under Shingles

As snow melts, water can seep beneath shingles—especially if your roof has:

• Damaged or missing shingles

• Worn flashing

• Aging roofing materials

• 
  

Once water gets underneath the roof system, it can lead to rot, mold growth, and insulation damage.

3. Added Weight and Structural Stress

Snow that partially melts becomes heavier as it absorbs water. This additional weight can:

• Strain roof decking

• Stress trusses and rafters

• Worsen existing structural weaknesses

• 
  

Older roofs or roofs already in poor condition are especially vulnerable.

4. Gutter and Drainage Issues

Melting snow needs a clear path to drain safely away from your home. Clogged or frozen gutters can cause:

• Water backup onto the roof

• Ice buildup along roof edges

• Damage to gutters and downspouts

• 
  

Proper drainage is critical to preventing winter roof damage.

Warning Signs of Roof Damage from Melting Snow

Watch for these signs during and after winter weather:

• Water stains on ceilings or walls

• Dripping or moisture in the attic

• Icicles forming along roof edges

• Peeling paint or warped drywall

• Sagging gutters or rooflines

• 
  

If you notice any of these issues, it’s important to act quickly.

How to Protect Your Roof During Winter

You can reduce the risk of damage from melting snow by:

• Keeping gutters clean and clear

• Ensuring proper attic insulation and ventilation

• Scheduling a professional roof inspection

• Repairing damaged shingles or flashing promptly

• 
  

Preventative maintenance can save you from expensive repairs later.
