Ice dams can cause significant damage to your roof if not addressed promptly. At Fasto Roofing, we provide effective strategies to prevent and remove ice dams, ensuring the safety and longevity of your roof.



What Is an Ice Dam?

An ice dam forms at the edge of your roof when warm air from the attic melts the snow on the roof. As the melted snow flows down, it refreezes at the colder edges, creating a ridge of ice. This ice dam traps water, which can seep through the roof and cause structural damage.


Why Are Ice Dams Dangerous?

Mold and Mildew Growth

  • Issue: Water penetration leads to mold and mildew in the attic insulation.

  • Consequence: Unpleasant odors and potential respiratory issues.


Roof Leaks

  • Issue: Water seeping through the roof deck causes leaks.

  • Consequence: Damages ceilings and interior structures.


Water Stains

  • Issue: Dripping water causes stains on ceilings and walls.

  • Consequence: Unsightly yellow or brown splotches.


Tear-Off Gutters

  • Issue: Heavy ice dams strain and tear off gutters.

  • Consequence: Further damage to the roof's edge and drainage system.


Prevention Tips

1. Have a Roof Inspection

  • Action: Schedule a professional roof inspection to identify problem areas.

  • Benefit: Early detection of issues that can exacerbate ice dam formation.


2. Clean Your Roof

  • Action: Regularly remove debris from the roof and gutters.

  • Benefit: Prevents water blockage and roof damage.


3. Shovel Snow

  • Action: Remove snow from the roof to prevent ice dam formation.

  • Benefit: Reduces the weight and buildup of snow and ice.


4. Insulate Ceiling

  • Action: Add extra insulation to the attic to keep warm air inside.

  • Benefit: Prevents melting snow and ice on the roof.


5. Use Heated Cables

  • Action: Install heated cables in gutters to prevent ice dams.

  • Benefit: Effective solution for keeping gutters clear of ice.


Removing Ice Dams

Safe Removal Methods

  • Hot Water: Use a garden hose connected to a hot water tap to melt the ice dam.
