Winter-Ready Metal Garages: Solutions For Michigan’s Climate

metal garages

The state of Michigan has some of the most unpredictable winter weather, from snowstorms and freezing rain to cold waves and lake-effect snow. Thus, it is crucial to prepare your metal garages to be winter-ready! The best thing about steel parking garages is that they can survive harsh weather conditions with little maintenance. So, you might be tempted to know how to prepare your garage for upcoming winters.

Snow, Sleet, & Metal Parking Garages: How To Prepare For Michigan Winter

1. Insulating Garage To Avoid Moisture From Freezing Rain & Snowmelts

It is necessary to install insulation with a metal parking shed as it provides a barrier against moisture, mold & mildew growth and reduces chances of condensation. It also reduces heat transfer to and from the metal garages. Some commonly used insulators are:

Type Of Insulator R-Value Key Features
Fiberglass insulation 3.1 to 4 per inch
  • Batt & rolls type insulator
  • Affordable
  • Best for insulating garage door
Cellulose Insulation 3.7 per inch
  • Blown-in type insulator
  • Made of recycled paper
  • Fire-resistant
  • Good thermal protection
Spray Foam Insulation Open: 3.5 per inch

Closed: 6 to 7 per inch

  • Open/ closed cell type of insulator
  • Closed cells has high R-value
  • Open cells are economical
  • Acts as moisture barrier
Woven Insulation 2 to 4 per inch
  • Made of interwoven fiberglass or mineral wool
  • High thermal resistance
  • Reduce radiant heat
  • Reduce heat transfer
Double Bubble 3.5 to 4 per inch
  • Two layers of air-filled bubbles between two layers of reflective aluminum foil
  • Easy to install
  • Effective against radiant heat

2. Pay Attention To Roof Design For Snow Shed 

It is crucial to have a roof designed with the correct angle and pitch to shed snow easily. The standard parking garage size in Michigan for one car is about 12’ x 20’, and for 2 cars is 24’ x 24’. Of course, the parking garage can be of larger size depending on the needs of the homeowner, and that’s why we suggest choosing a roofing style that helps combat all weather situations.

When it comes to metal garages, one can choose a vertical roofing style with corrugated panels. For a smaller garage, one can pick horizontal roofs as they cost less than vertical but are not as effective in shedding snow & rainwater.

Regular Roof Design [Good] : ideal for small metal sheds and carports
Boxed Eave Roof Design [Better] : ideal for small to medium steel garages and carports

: suitable for moderate weather

Vertical Roof Design [Best] : ideal for large size metal buildings

: suitable for harsh weather conditions

Tip: You can add reinforced roofing material to handle the weight of snow and ice falling over it.

2.1 Choose Right Pitch & Style Of Roof With High Snow Load Capacity

A roof pitch of 6:12 is best for a better snow shed. It will also help maintain the structural integrity of the entire structure. You can choose certified steel buildings that can withstand snow loads of up to 80 pounds per sq. ft. These are engineered-certified garages with 12-gauge steel frames and vertical roofs.

Ensure cleaning of snow from the roof to prevent overload or potential collapse. You can use a roof rake, broom, professional snow blower, or snow melting system.

Tip: Check manufacturer guidelines before using any tools.

3. Check Heating System For Comfortable Indoors

Most Americans spend their weekends in their garages, and some prefer to have a home office or a workshop in them. By installing a heater, Michigan residents can keep garage space warm and prevent freezing of pipes or equipment. Some even choose to install a thermostat to maintain a consistent temperature inside and avoid overheating.

4. Clean Landscaping Around The Garage & Over It

Before the arrival of winter and snowflakes, it is necessary to clear debris over the roof and around the steel garages. Remove any dead leaves, branches, and other debris that can cause potential blockage in gutters and drainage systems. It can lead to water blockage and ice dams.

Next, clear the driveway by removing any vegetation and ensure easier access to the garage, even when snow or ice accumulates. Trim overhanging trees or shrubs that can break under heavy snow and damage the garage.

Clear off any organic debris to avoid pests seeking shelter or food around the garage during winter. Trim tall grasses nearby to improve visibility. A clear landscape around the garage will help you remove snow effectively.

5. Corrosion Resistant Material To Avoid Rusting

Choose a durable, long-lasting material that can bear more weight. One such example is a metal parking space. One of the common myths about steel buildings is that they are flimsy, corrode easily, and have a lengthy construction process.

Opt for 100% galvanized steel garages with zinc coating around them to prevent rust development. Not only that, it is also an eco-friendly material that can be recycled endlessly without losing its strength and durability.

You can choose between a 12-gauge [cost about 20 to 30% more] or a 14-gauge steel frame as per your local building code, local climate zone, and your budget.

6. Secured Anchors & Braces To Resist Snowstorms, Ice Storms, Cold Waves

Another helpful tip will be to add extra anchors to the foundation and frame. This will provide strength to the overall structure and resist strong winds. Add extra braces and purlins to increase roof support and provide extra strength.

7. Proper Ventilation

Having vents will manage humidity and prevent condensation inside the parking garage. It will bring in fresh air and expel warm, moist air that can fuel mold and mildew growth. Some examples of vents that you can install in a steel parking garage are:

Ventilation Type Installation Place
Soffit Vents : along the eaves of the roof
Ridge Vents : at the peak of the roof
Gable Vents : on the gable ends of the garage
Roof Turbine Vents : on the roof [around center]
Attic Fans : in the attic
Ventilation Baffles : between roof rafters

Tip: You can use one or a combination of two or more for optimal performance.

Maintenance Tips For Metal Garages This Winters

  1. Inspect the roof and side walls to see if there are any fading paint, minor rusting, cracks, holes, or small punctures. If you notice any issue, fix it before the winter arrives.
  2. Check weatherstripping around windows and doors on the roof and gutters. It will keep cold air and moisture out.
  3. You can install de-icing agents to prevent ice buildup on the roof and around the garage. Some examples are roof snow guards, de-icing cables, steam ice removal, etc.
  4. Be sure the gutter and downspouts are clean and free from debris that can clog the pipe. You can install a gutter guard for easy & less frequent cleaning.
  5. You can invest in dehumidifiers or moisture absorbers inside the garage to keep the air dry. Also, check the exterior of the garage, especially around the foundation edges, to check for cracks. If you notice any, fill it with silicone-based waterproof sealant.
  6. Finally, look for signs of minor rust. If you notice one, scrub it with sandpaper, apply metal primer, and finish it up with a metal paint coating.

Prepare Your Metal Garage For Michigan Winters

Steel garages are designed to hold heavy snow loads with their sturdy vertical roof construction that enhances snow shedding easily. These parking spaces provide a secure and reliable storage cum parking for all your vehicles and equipment. You can even add heating options like heaters or radiant floor heating to keep you toasting when working on DIY projects in the garage. What are your thoughts on it!?
