While sleet may not be as common in some regions as snow or rain, it can still pose a significant threat to your roof. Sleet is a frozen mixture of rain and snow, consisting of small ice pellets. When sleet accumulates on your roof, it can cause various forms of damage over time. At Danley Roofers, we want to help homeowners understand the potential risks of sleet and how to protect their roofs.

**1. Impact Damage: Sleet pellets can vary in size, and when they accumulate on your roof, they can create a substantial weight load. If sleet accumulates and freezes, it can become heavy, leading to impact damage. The force of falling sleet can weaken or crack roofing materials, such as shingles or tiles.

**2. Ice Dam Formation: When sleet melts during the day and refreezes at night, it can contribute to the formation of ice dams along your roof’s edge. Ice dams block the natural flow of melting snow and ice, causing water to pool on your roof. This trapped water can seep beneath your roofing materials, leading to leaks and structural damage.

**3. Roof Shingle Damage: Sleet can be abrasive and may cause granule loss on asphalt shingles. When granules are dislodged, it weakens the shingle’s protective layer, making your roof more susceptible to damage from UV rays, moisture, and other environmental factors.

**4. Gutter and Downspout Issues: Accumulated sleet can clog your gutters and downspouts, preventing proper drainage of rainwater and melting ice. This can lead to overflow and water seeping into your home’s foundation, causing water damage and potential structural issues.

**5. Sealing and Flashing Damage: Sleet can damage the sealing and flashing around roof penetrations like chimneys, vents, and skylights. When these areas are compromised, water infiltration becomes more likely, leading to leaks and potential interior damage.

**6. Cracked or Broken Tiles: For homes with tile roofing, the impact of sleet can cause tiles to crack or break. Damaged tiles not only compromise the aesthetics of your roof but also leave it vulnerable to water intrusion.

**7. Ice Melt Runoff: As sleet accumulates on your roof, it can melt and run down the surface, refreezing at the eaves. This creates an ice dam that prevents proper drainage. The resulting backup of water can lead to leaks and structural damage.

**8. Attic Moisture Issues: Sleet can infiltrate your attic if your roof is not adequately sealed or insulated. Moisture in the attic can lead to mold growth, wood rot, and structural deterioration.

Preventing Sleet Damage:

Protecting your roof from sleet damage involves a combination of proactive measures and regular maintenance:

  • Proper Insulation and Ventilation: Ensure your attic is well-insulated and adequately ventilated to prevent moisture buildup and ice dam formation.
  • Regular Roof Inspections: Schedule regular roof inspections with a professional roofing contractor to detect and address any damage or vulnerabilities.
  • Gutter Maintenance: Keep your gutters and downspouts clear of debris to allow for proper drainage.
  • Roof Repairs: Promptly address any damage or leaks identified during inspections or severe weather events.
  • Roof Replacement: If your roof is aging or has sustained extensive damage, consider investing in a roof replacement to ensure your home’s long-term protection.


Sleet may be less common than other forms of precipitation, but it can still cause significant damage to your roof over time. Recognizing the potential risks and taking proactive measures to protect your roof is essential for maintaining the integrity of your home. If you have concerns about your roof’s condition or have experienced sleet-related damage, don’t hesitate to contact a reputable roofing contractor like Danley Roofers for expert guidance and solutions.
