Winter in Utah is no small thing, especially when it comes to your roof. From Park City’s powdery snow to the heavy, wet accumulation in the valleys, each storm tests the strength and structure of your home’s first line of defense. At Timberline Roofing, we know Utah weather because we live and work right here in it. We’ve seen what lake-effect snow, freeze-thaw cycles, and unexpected blizzards can do to roofs, and we’ve helped homeowners prepare, repair, and rebuild with confidence.
As a local, community-focused roofing company, we provide roofing solutions built to handle Utah’s extreme seasons, from hot, dry summers to long, icy winters. Our residential services include asphalt shingles (architectural and premium), metal roofing (steel, corrugated, standing seam, exposed fastener), synthetic tile roofing, cedar shake or shingle, and residential flat roofing. We also handle gutters (K-style, half-round, seamless aluminum) and emergency roof solutions such as tarping, leak repairs, and storm damage assessments.
When winter storms roll in, one of the most common questions homeowners ask is: How much snow is too much? The answer depends on your roof type, design, and material. Let’s break it down by roofing style so you can understand what your home can safely handle.
Understanding Snow Load Basics
Snow load is the weight of snow and ice sitting on your roof. In Utah, the average residential roof is designed to handle 30 to 60 pounds per square foot (psf), depending on the location and elevation. For example, a home in Salt Lake City may be designed for 30 psf, while a cabin in Heber or Logan might be engineered for 60 psf or more.
To put that in perspective, 12 inches of fresh, light snow weighs about 5 pounds per square foot, but 12 inches of wet, heavy snow may weigh up to 20 pounds per square foot, and when that builds up layer by layer, it adds up quickly. That’s why choosing a roofing material that complements your home’s structural strength and local climate is so important.
How Different Roofing Materials Handle Snow
1. Asphalt Shingles: Most Utah homes feature asphalt shingles because they’re durable, affordable, and versatile. A well-installed asphalt shingle roof can typically handle 20 to 40 psf of snow load, more than enough for most valley and foothill regions. The key is proper installation and attic ventilation, which helps prevent ice dams that trap melting snow and add weight unevenly.
Pro Tip: Architectural and premium shingles offer added thickness and wind resistance, which means they’re better equipped to withstand snowdrifts and fluctuating temperatures.
2. Metal Roofing (Steel, Standing Seam, Corrugated, Exposed Fastener): Metal roofing is one of the best choices for Utah’s snowy climate. It’s incredibly strong and designed for 40 to 70 psf snow loads, depending on panel type and gauge. Plus, the smooth surface encourages snow to slide off naturally, reducing buildup and minimizing strain on the structure. Standing seam and corrugated panels perform especially well in areas with frequent freeze-thaw cycles because they resist cracking and corrosion.
Bonus: Metal roofs reflect sunlight and can melt snow faster, which helps prevent ice dam formation near the eaves.
3. Synthetic Tile Roofing: If you love the look of tile but want something lightweight, synthetic tile is a smart upgrade. Unlike traditional clay or concrete, which can be extremely heavy, synthetic tiles are engineered to be lightweight yet durable, supporting snow loads of up to 60 psf without stress on your roof framing. They’re also impact-resistant, a big plus when ice slides down after a thaw.
Why it’s great for Utah: Synthetic materials don’t absorb water, so they won’t crack during sudden temperature drops.
4. Cedar Shake and Shingle Roofing: Cedar roofs bring a classic mountain-home charm, especially in wooded areas or ski towns. While cedar itself is strong, its performance depends on proper maintenance and ventilation. A well-maintained cedar roof can safely hold 30 to 40 psf, but heavy snow should be cleared periodically to prevent uneven loading or ice buildup.
Tip: Applying a quality sealant and ensuring proper slope can greatly extend the life and strength of a cedar roof in snowy regions.
5. Residential Flat Roofing: Flat roofs are common on modern homes and certain additions, but they require special attention during Utah winters. Because snow can’t slide off, these roofs must be built for higher loads, typically 50 to 70 psf, depending on the design. Regular snow removal is essential to prevent ponding water or excess weight after a storm.
We recommend Scheduling professional inspections each fall to ensure your flat roof’s drainage system is clear and ready.
Protecting Your Roof Before and After a Storm
Even the strongest roof can be tested by back-to-back storms or extreme temperature swings. Here’s what you can do:
- Inspect annually. Have a professional check for weak spots, leaks, and insulation issues before winter.
- Clear snow safely. Use a roof rake or call a professional — never climb up yourself in icy conditions.
- Watch for warning signs. Creaking noises, sagging drywall, or doors that stick can indicate excess snow weight.
