How Weather Can Affect Your Metal Roofing Material Choices

When you are needing to choose roofing materials, it is easy to focus on the final look of the finished roof. The color you choose, along with the panel style all matter, but the weather your building will experience should also play a major role in your decision.

No matter where you are around the world, your roof may need to handle freezing temperatures, heavy snow, strong winds, rapid temperature changes, or intense summer sun. These conditions can put different types of stress on roofing supply Idaho Falls throughout the year.

Metal roofing is a popular choice for buildings because of its strength and durability. However, not every metal roofing system is exactly the same. The panel profile, gauge, coating, and other components can all affect how the roof performs in different conditions.

Snow and Heavy Winter Weather

Snow is one of the biggest considerations for buildings, especially in the Eastern Idaho area. A roof needs to be able to handle the weight of snow while also directing water away from the structure the right way as that snow melts.

When choosing metal roofing for a snowy climate, be sure to consider:

  • The roof's slope and design
  • The panel profile
  • The gauge of the metal
  • Proper trim and flashing
  • Snow management accessories
  • The overall structure supporting the roof

A stronger roofing system is important for buildings that experience a lot of snowfall over the year. Standing seam and structural metal panels can be beneficial depending on the design and needs of your building.

Strong Winds Can Put Roofing to the Test

Wind is another factor that should not be overlooked. Strong gusts can put pressure on roofing panels, fasteners, trim, and other parts of the roofing system.

The way a metal roof is installed matters just as much as the panel itself too. Properly secured panels and correctly installed trim help create a finished system that can better withstand changing weather conditions. Standing seam metal roofing is one option that uses concealed fasteners, creating a clean appearance while reducing the number of exposed fasteners on the roof.

Temperature Changes and Metal Roofing

A roof could go from freezing winter temperatures to hot summer conditions and back again within a matter of months in so many different areas.

These changes cause building materials to expand and contract. Choosing quality materials and making sure they are properly installed can help the roofing system handle these normal changes over time. This is also why it is important to consider the entire roofing system rather than focusing only on the panels.

Summer Sun and UV Exposure

Winter isn't the only season that can affect your roof. Idaho summers can bring plenty of direct sunlight and UV exposure.

Over time, exposure to the sun can affect some roofing materials, particularly their color and surface finish. Metal roofing with protective coatings can help resist fading and weathering while maintaining the appearance of the roof. When choosing a color and finish, it is worth considering how the roof will look after years of exposure to the sun and not just how it looks on the day it is installed.

Moisture and Changing Weather Conditions

Rain and moisture can create problems when water is not properly directed away from a building. A good roofing system needs to account for water around roof edges, valleys, seams, penetrations, and transitions. This is where the smaller components of a roofing project become important.

Depending on the project, roofing materials may include:

  • Ridge caps
  • Eave trim
  • Valley trim
  • Flashing
  • Drip edges
  • Roof boots
  • Closures
  • Underlayment
  • Snow guards

These components work together with the panels to help manage water and protect vulnerable areas of the roof.

Does Metal Gauge Matter?

Metal gauge is another factor to consider when choosing roofing materials. A lower gauge number generally means thicker steel, so 24-gauge and 26-gauge panels are not exactly the same. The best choice depends on the type of building and the expected conditions.

Rather than choosing a gauge based only on price, consider what the building actually needs and discuss the available options with your metal roofing supplier.

Choosing Materials Specifically for Idaho Weather

Weather is not something you can control, but you can choose materials that are appropriate for the conditions your building will face.

Before ordering your metal roofing, be sure to consider:

  • How much snow the area typically receives
  • Potential wind exposure
  • Summer sun and UV exposure
  • Temperature changes throughout the year
  • The slope and design of the roof
  • The type of building being constructed
  • The appropriate panel profile and gauge
  • The trim and accessories needed for proper installation

A roofing supplier can help you look at these factors together instead of treating each material as a separate decision.

Choosing a metal roofing system is about having the right combination of panels, gauge, trim, flashing, and accessories can help create a roof that is prepared for the weather your building will experience year after year.
