Central Michigan is known for having cold winters, but many people overlook how much the temperature can skyrocket in the summer. This feeling is noticeable inside, with hot rooms and overworked AC units.  Contractors and homeowners can consider cool metal roofing as a superior choice to keep their home cool when temperatures rise, while keeping their energy bills low. 

Metal roofing has come a long way over the years, and today’s systems are designed with heat control in mind. It’s another reason why this roofing material has gained popularity in recent years. Learn more about why it’s a great option for those hot summers in Michigan.

What Makes Cool Metal Roofing “Cool”?

Cool metal roofing is a superior choice in the scorching heat of a Michigan summer. It’s engineered to reflect heat intentionally. Instead of soaking up the sun’s energy, metal panels bounce a significant portion of it away from the home. Reflective roof coatings are at the core of why this material is so effective in the summer. These coatings are engineered to reflect solar radiation rather than letting it transfer into the attic space. Lighter-colored metal roofs tend to reflect even more heat, but modern coatings make darker colors more effective than ever.

Modern roofing shingles have superior benefits over traditional shingles. While they are lightweight, these shingles are incredibly energy efficient and come in a variety of colors to match your preferences. Choosing this material allows heat to escape quickly instead of lingering and warming the structure below. The end result is a cooler, more efficient home that can save hundreds of dollars annually.

The Role of Ventilation in Metal Roofing Systems

Even superior roofing materials need proper ventilation to keep your home’s interior comfortable. One reason cool metal roofing works so well is that it pairs naturally with effective ventilation strategies. These systems are often installed over shingles, which tend to trap air in hot attic spaces.  Having the metal shingles placed directly over the existing roof creates an air gap, allowing heat to escape more easily. This essential space is key to keeping the attic cooler and reducing the heat load on the AC system. Homeowners can have the peace of mind they deserve without constantly needing to adjust the thermostat.

Cool Metal Roofing vs. Asphalt Shingles in Hot Climates

There’s a reason why you’re probably noticing more metal roofs installed in neighborhoods throughout the central Michigan area. While shingles are a good choice, they are also known for trapping heat, which can drive the temperatures (especially in the attic) sky high. In peak summer conditions, asphalt roofs can reach surface temperatures well above the outdoor air temperature. Metal roofing is highly reflective in nature, meaning it naturally keeps your home cooler than asphalt shingles. It can reduce attic temperatures by more than 5 to 10 degrees compared to asphalt options, giving homeowners a real option to save money on their energy bills. 

Longevity matters too when you’re making an investment in your property. Summer heat and different external factors can make asphalt roofs break down much faster. They often need replacing every 10-15 years, while metal roofs can last up to 50 years or more. Imagine the savings over that timeframe if you made the switch.

ENERGY STAR® Rated Metal Roofing Benefits

Many metal roofing products meet ENERGY STAR® requirements, which means they meet or exceed the requirements for solar reflectance and thermal performance. While it’s not the only factor to consider, it does give Michigan homeowners more confidence in choosing a product that is designed for maximum performance and reduced energy consumption. Anytime they can save money with a superior product matters, especially with ever-increasing energy costs.

Comfort And Long-Term Value

Cool metal roofing is a great choice for comfort during a hot summer, but you are also investing in products that you’ll appreciate for decades to come.  Lower attic temperatures can reduce strain on HVAC systems, potentially extending equipment life. Some homeowners even notice more consistent temperatures throughout the house, especially on upper floors.

Many contractors also enjoy working with lightweight, yet durable roofing materials. It can be simpler to install, and service or maintenance requests can be handled more efficiently. When a client wants a roof that lasts longer, looks great, and keeps the home cool during summer, metal roofing is something that checks all the boxes. Even property owners who don’t need a new roof still consider it because they understand the long-term value and savings they’ll get.

More homeowners in Michigan are starting to realize the benefits and value of metal roofing.  One common question many of them have is how to replace an existing roof that has shingles on it. Can you put a metal roof over shingles? The short answer is yes, but there are several factors to consider. The longer answer depends on your roof’s condition, local building codes, and whether the pros outweigh the cons for your specific home.

Let’s break it down in plain language so you can decide if this option makes sense for your central Michigan property.

When Is It Possible to Install a Metal Roof Over Shingles?

Certain conditions need to exist if you want to place a metal roof over shingles. The existing roof has to be in decent condition, meaning it must be flat and structurally sound. There can be no major dips or signs, or significant rot or decay.  If your shingles are already curling, soft, or hiding leaks, covering them up will only make problems worse.

Underlying roof structure matters as well. Modern metal roofing is durable and lighter than before, but adding a new layer still increases the overall load. Your roof decking and framing must be able to support the added weight safely. It’s also imperative to understand your city’s local building codes.  In Michigan, most jurisdictions follow the Michigan Residential Code (based on the International Residential Code). Generally, these codes restrict how many layers of roofing material you can have. If your home already has multiple layers of shingles, a tear-off may be required before installing metal.

Finally, ventilation is another factor that shouldn’t be overlooked. Good ventilation allows your roof to last longer because it helps prevent moisture buildup and heat damage. Installing a metal roof over existing shingles without proper ventilation can trap heat and moisture. This can decay the underlying structure.

Advantages Of Installing A Metal Roof Over Shingles

If you’re considering putting a metal roof over your shingles, it provides several benefits.

1. Cost Savings: If you’re hiring a company to install your metal roof, it can save you money by skipping the labor to tear off the existing shingles. Even as a DIY project, it will save you money because you won’t have to pay for the disposal of old shingles. ( like hauling it away).
2. Faster installation: New roof installation can be somewhat of a hindrance for busy homeowners. Placing metal over shingles can significantly reduce installation time.
3. Added insulation: Having an additional layer of roofing material can be an excellent insulator when temperatures in Michigan plunge in the winter season.
4. Less Mess: Tearing off an existing roof can create lots of debris and chaos around the property.

This option is good if you want to save time and money while keeping your home’s exterior in check.

Drawbacks Of Installing a Metal Roof Over Shingles

While covering your existing shingles has its benefits, you should also consider the risks of not removing them first.

1. Concealed issues: There could potentially be underlying issues you’re not aware of, like structural damage, rot, and decay. Laying metal over it could make the issue much harder to repair.
2. Uneven surface:  It’s difficult to lay metal shingles perfectly over existing shingles. If done incorrectly, the metal panels can warp or ripple. This will reduce their aesthetic appearance and functionality.
3. Potential Code Violations: Depending on local ordinances and the number of existing layers, installing a new roof over the old one may violate building codes, leading to problems during resale or insurance claims.
4. No Opportunity for Deck Inspection: When a tear-off is skipped, the roof deck (the foundation under the shingles) cannot be fully inspected for damage, meaning weak or rotted sections may go unnoticed and compromise the new roof’s structural integrity.

How To Make The Best Decision For Your Michigan Property

Ultimately, making the decision to install a metal roof over shingles comes down to the current condition of your roof and considering local codes. It’s often a great choice for sound roofs with only one layer of shingles, offering significant savings and a faster installation. However, if there are existing leaks, structural damage, or multiple layers already present, a complete tear-off is the safer and smarter investment to ensure the longevity and performance of your new metal roof.
