Snow Load on a Roof Asphalt vs. Metal Roofing in Ohio

February 2, 2026 | Filed under: News

Ohio Winters bring a mix of heavy snow, freezing rain, sleet, and constant temperature swings. These conditions put serious stress on roofing systems, and the type of roof installed plays a major role in how well snow and ice are managed throughout the season. Let’s dive into why having snow loads on your roof are harmful to your structure.

For both residential and commercial properties across Ohio, asphalt shingles and metal roofing handle snow try differently-and those differences matter.

Snow Load on a Roof with Asphalt Shingles

Asphalt shingle roofs hold on to snow longer than most homeowners expect. The granulated surface of asphalt shingles create friction, which keeps snow in place instead of allowing it to slide off naturally.

As outdoor temperatures fluctuate, heat escaping from the building causes snow to melt unevenly. When that meltwater refreezes near the eaves, ice dams form. These ice dams trap water on the roof and push moisture underneath the shingles, increasing the risk of leaks, rotted decking, and interior damage.

Cheap and faulty flashings that come with asphalt shingle roofs are also areas of penetration when dealing with snow and ice. These flashings are used in high-risk areas such as chimneys, skylights, and dormers. These areas are where we commonly find rotted roof decking when doing a roof installation.

Ohio’s frequent freeze-thaw cycles also accelerate wear on asphalt shingles. Shingles expand and contract repeatedly, which leads to cracking, curling, and granule loss over time. Older roofs and lower-quality installations tend to show damage first, especially after harsh winters.

Snow Load on a Roof with Metal Roofing

Metal roofing handles snow far more efficiently in Ohio’s climate. The smooth surface of metal panels and shingles allows snow to slide off as it warms or becomes heavy. This natural shedding reduces the amount of snow and weight sitting on the roof.

By shedding snow quickly, metal roofs limit the conditions that cause ice dams to form. Meltwater drains away instead of refreezing at the eaves, which helps protect the roofing system and the building below.

When snow control is needed-such as above walkways, entrances, or parking areas-installers add snow guards. These devices release snow gradually, preventing large sheets of snow from sliding off all at once while still maintaining the roof’s performance.

Why Reducing Snow Load on a Roof Matters in Ohio

Many Ohio homeowners and commercial property owners choose metal roofing for its durability and winter performance. Schroer & Sons Metal Roofing installs metal roofing systems designed to handle heavy snow, ice, and repeated freeze-thaw cycles common throughout the state.

Unlike asphalt shingles that usually require a replacement every 10-15 years, metal roofs deliver long-term performance with minimal maintenance. Protective coatings resist moisture, rust, and deterioration, even during extended wet winters.

Metal roofing also provides consistent performance across residential homes, agricultural buildings, churches, and commercial facilities-structures that often face higher snow loads and longer exposure to winter conditions.

Asphalt vs. Metal Roofing: Snow Performance Comparison

• Snow Behavior
  • Asphalt Shingle Roofs – Snow stays in place
  • Metals Roofs – Snow slides off more easily
• Ice Dam Risk
  • Asphalt Shingle Roofs – Higher risk in Ohio winters
  • Metals Roofs – Lower risk when properly installed
• Freeze-Thaw Impact
  • Asphalt Shingle Roofs – Shingles wear faster
  • Metal Roofs – Metal resists expansion damage
• Winter Maintenance
  • Asphalt Shingle Roofs – More frequent inspections needed
  • Metal Roofs – Less winter maintenance required
• Lifespan
  • Asphalt Shingle Roofs – Shorter-term Solution
  • Metal Roofs – Long-term of Lifetime Solution

Snow Load on a Roof for Ohio Commercial Buildings

Commercial and agricultural buildings across Ohio often face higher snow loads due to large roof spans and lower slopes. Asphalt systems must support that weight until the snow melts, which increases long-term stress on the structure.

Metal roofing reduces that burden by shedding snow instead of storing it. Properly engineered metal systems help protect structural integrity while lowering winter maintenance demands for property owners and facility managers.

Final Thoughts

Ohio’s winters demand roofing systems that manage snow, ice, and moisture effectively. Asphalt shingle roofs tend to retain snow and suffer increased wear from ice dams and freeze-thaw cycles. Metal roofs actively shed snow, reduce ice buildup, and maintain performance through harsh winter conditions.

For Ohio homeowners and commercial property owners focused on durability, safety, and long-term value, metal roofing-such as the systems installed by Schroer & Sons Metal Roofing-offers a strong solution built for the realities of Midwest winters.
