Snow‑Load‑Smart Roofs For Midway Homes

Will your Midway roof keep up when Heber Valley storms stack feet of snow overnight? If you own or plan to buy in Midway, you want a home that stays safe, dry, and easy to maintain in winter. In this guide, you’ll learn how to choose, upgrade, and care for a roof that handles local snow loads, reduces ice-dam risk, and meets permitting and insurance expectations. Let’s dive in.

Know your site snow load in Midway

Understanding your site’s ground snow load is the first step. Use the Utah Ground Snow Load interactive map to get a location-specific estimate for your property and elevation. The tool provides 50-year predictions designers use to size roof structures. You can check your address at the Utah State University tool and save the result for your records.

Midway sits at a similar elevation to Heber City. Utah’s statewide code amendments list Heber City at 60 psf ground snow load, which many Midway sites use as a baseline. Always confirm your exact value with the Midway building official during plan review, since terrain and elevation can change requirements. You can find permitting and design criteria links on Midway City’s Building Permits & Inspections page.

Ground vs. roof snow load

“Ground snow load” pg is the starting point. Engineers convert pg to a design roof load using ASCE 7 methods. A common flat-roof conversion is pf = 0.7 × Ce × Ct × Is × pg, then checks for drifts, unbalanced loading, slope, and rain-on-snow are added. These details often control member sizing, especially near valleys and at changes in roof height. For exact calculations, professionals follow the adopted ASCE 7 provisions and local amendments.

Roof designs that work in Heber Valley snow

Pitch and geometry

Steeper roofs shed snow faster, which can lower sustained uniform loads. On very smooth, steep metal roofs, that shedding can become sudden slides onto walkways or driveways below. Low-slope roofs hold more snow, which raises design loads and makes drainage and drift checks more critical. Complex roofs with valleys or multiple levels often need specific drift calculations at transitions.

Materials that manage snow

• Metal standing seam: durable and sheds snow well. Because it sheds, you often need snow-retention systems to protect people, landscaping, and gutters.
• Asphalt shingles: higher friction holds snow in place, which limits big slides but increases roof loading. The structure must be sized accordingly.
• Tile or slate: long lasting and snow friendly, but heavier. Your framing must be designed for the added dead load plus winter drifts.

Snow retention where it matters

Snow guards and rail systems prevent uncontrolled slides and help snow release in small amounts. They are essential above entries, walkways, driveways, decks, garages, and over mechanical equipment, especially on metal roofs. Placement and attachment should be engineered and connected to structural members, not just the roofing surface.

Stop ice dams before they start

Ice dams form when heat from inside the home warms the roof deck, melts snow, and refreezes at cold eaves. The fix is to keep the roof deck uniformly cold and protected.

Key steps:

• Air seal the attic and all penetrations.
• Add insulation to meet or exceed current energy code levels.
• Balance ventilation with intake at eaves and exhaust at the ridge.
• Use an ice-and-water barrier underlayment at eaves and valleys for backup protection.

Heat cables can help manage icing at eaves and gutters, but they are a supplement, not a root-cause solution. For a homeowner-friendly walkthrough, see this guide to prevention and removal: Ice-dam prevention basics

When to reinforce your roof

Consider structural upgrades if your roof framing predates current snow-load assumptions, if you plan to install heavier materials like tile or slate, or if you notice sagging, new interior cracks, or leaks after storms. A licensed structural engineer will evaluate uniform, unbalanced, drift, and sliding loads, then size members or bracing accordingly. Most framing changes require plans, permits, and inspections through Midway City.

Permits, inspections, and insurance in Midway

Midway requires permits and plan review for roof replacements that affect structure and for most structural changes. Inspectors check framing, nailing, and engineered details against approved plans, so keep your plans and truss specs on site. Start at the city’s resource page: Midway City Building Permits & Inspections

Insurance policies often cover sudden roof collapse from a covered peril, but details vary by age, exclusions, and replacement terms. Document upgrades and speak with your insurer before major work so you understand coverage. See this overview: Homeowners insurance and roof coverage

For safety, avoid climbing onto snowy roofs without proper training and fall protection. Use a roof rake from the ground for light removal, and hire licensed pros for large accumulations or ice dams. A practical refresher is here: Safe ice-dam removal tips

Quick Midway checklist

• Verify your parcel’s ground snow load with the USU tool, then confirm with the building official.
• Plan roof geometry with an engineer to manage drifts at valleys and level changes.
• Choose materials with snow behavior in mind, and size the structure for the total load.
• Add snow guards or rails where people walk, park, or gather below eaves.
• Air seal, insulate, and ventilate the attic; use ice-and-water barrier at eaves and valleys.
• Pull permits for structural work, and keep approved plans on site for inspections.
• Document upgrades and talk to your insurer about coverage.
• Set a safe snow-removal plan for big storms.

A winter-smart roof protects your investment and your peace of mind. If you are buying or selling in Midway or Heber Valley, you can make better decisions when you know how a home handles snow and ice.

FAQs

How do I find my Midway home’s required snow load?

• Start with the Utah Ground Snow Load map, then confirm the exact design load with the Midway building department or a licensed engineer during plan review.

What is the difference between ground and roof snow loads?

• Ground snow load pg is the base estimate; engineers convert it to a roof load and add checks for slope, drift, unbalanced loading, and rain-on-snow per ASCE 7.

Do I need snow guards on a metal roof in Midway?

• Usually yes, especially above entries, walks, or driveways; use engineered systems attached to structural members, not just into panels.

Can heat cables alone stop ice dams on Midway homes?

• No, they help manage icing at eaves but do not fix heat loss; pair cables with air sealing, insulation, ventilation, and proper underlayment.

When should I call an expert after a big storm?

• Call a roofer or engineer if you see sagging, new interior cracks, leaks, or heavy drifts and ice; early action is safer and often less costly.
