Which Is More Energy Efficient: Metal or Shingles Roof?

Energy efficiency is one of the most important factors to consider when replacing your roof. Homeowners seek ways to reduce energy costs while protecting their homes from the elements. Two standard roofing options—metal roofs and asphalt shingles—have advantages.

However, when it comes to energy efficiency, there are key differences that can make one option more appealing than the other. This article will explore these differences and help you decide which roofing material is the most energy-efficient for your home.

Can You Lay Metal Roofing Over Shingles?

It is possible to lay metal roofing over existing shingles, and it’s often recommended as an efficient way to install a new roof. This process is known as a roof-over; it can save time and money since it eliminates the need to tear off the old shingles. 

However, ensuring the existing roof is in good condition is essential. Any damage or structural issues could compromise the integrity of the new metal roof. In terms of energy efficiency, installing a metal roof over shingles can improve your home’s insulation by adding another layer of protection from the elements.

Is a Metal Roof Cheaper Than Shingles?

Upfront costs are an essential factor when comparing metal roofs and shingles. On the surface, asphalt shingles are cheaper, with standard shingles costing between $60 and $90 per square (100 square feet). In contrast, metal roofs can range from $400 to $3,000 per square. 

Although metal roofs have a higher initial cost, their longevity, and durability can make them a more cost-effective option in the long run. Metal roofs can last 40 to 70 years, while asphalt shingles typically last 15 to 30 years. Moreover, metal roofs often require fewer repairs and replacements, which can offset the higher initial installation cost over time.

Are Metal Roofs Better Than Shingles?

When considering which roofing material is better, metal roofs have several advantages. Metal roofing is more durable and capable of withstanding harsh weather conditions such as strong winds, hail, and heavy rain. It is also fire-resistant and can offer better protection for your home. Regarding energy efficiency, metal roofs have reflective properties that can help reduce heat absorption. This means they can keep your home cooler in the summer by reflecting sunlight rather than absorbing it, ultimately lowering cooling costs.

In contrast, asphalt shingles are more prone to wear and tear over time, especially in extreme weather conditions. They can absorb heat, which may increase cooling costs during warmer months. While shingles can be an effective and affordable choice for some, metal roofs typically outperform them in terms of durability, longevity, and energy efficiency.

Choosing the Right Roof for Energy Savings

Both metal roofs and asphalt shingles have their merits, but if energy efficiency is your primary concern, metal roofing is the superior option. With its reflective qualities, longer lifespan, and durability, a metal roof can significantly reduce your energy bills while offering long-term protection for your home. While shingles may be more affordable upfront, metal roofs provide savings in fewer repairs, lower energy bills, and potential insurance discounts. 

When choosing between the two, you must consider your long-term goals and the climate in which you live.
