The Ultimate Guide to Upgrading Your Roof: Metal Roofing Over Asphalt Shingles

Updated: Apr 9

Transform Your Home with a Metal Roof Overlay

Within the sphere of home renovation, opting to enhance your roofing material is a choice that profoundly influences your property's appearance and utility. A prime upgrade is the application of a metal roof atop current asphalt shingles, a strategy endorsed by Roof Repair Albany NY. This approach not only boosts your roof's resilience and lifespan but also aids in energy conservation and imparts a contemporary touch to your home's facade.

The Benefits of Choosing Metal Roofing

Opting for metal roofing presents numerous advantages, including its remarkable durability, resistance to extreme weather conditions, and minimal maintenance requirements. Metal roofs are known for their ability to reflect solar radiant heat, which can reduce cooling costs during warmer months. Additionally, metal roofing materials are typically recyclable, making this option both eco-friendly and sustainable.

Evaluating Your Current Roof Condition

Before proceeding with a metal roof overlay, it is crucial to assess the condition of your existing asphalt shingle roof. A metal roof can be installed over shingles if the current roof structure is solid, there are no significant damages, and local building codes permit overlays. However, this approach might not be suitable for every situation. If the existing roof is in poor condition or has multiple layers of shingles, a complete tear-off and replacement might be the more prudent option.

Installation Process and Considerations

Installing a metal roof over asphalt shingles requires meticulous planning and precision. It involves laying down a breathable synthetic underlayment over the shingles to create a barrier that prevents moisture accumulation. Following this, metal panels or shingles are securely fastened to the roof, ensuring a robust and weather-tight seal.

One key factor to consider is the potential increase in weight. Although metal roofing is relatively lightweight, it's important to verify that the existing roof structure can support the additional load without compromising integrity.

Advantages and Drawbacks of Metal Roof Overlays


  • Cost Efficiency: Overlaying a metal roof can be more economical than a full replacement, as it eliminates the need for debris removal and disposal.

  • Quick Installation: This method is generally faster, reducing labor costs and minimizing disruption to your daily routine.

  • Enhanced Protection: An overlay provides an extra layer of defense against environmental elements.


  • Limited Suitability: Not all roofs are candidates for an overlay, depending on their condition and local regulations.

  • Future Replacement Costs: When the time comes for a new roof, the presence of multiple layers may complicate and increase the cost of removal.

  • Potential for Unaddressed Issues: Overlaying might mask underlying problems, such as damaged decking or leaks, which could lead to more significant issues down the line.

Making an Informed Decision

Choosing to install a metal roof over asphalt shingles is a decision that should not be taken lightly. It requires thorough evaluation of your current roof's condition, consideration of local building codes, and an understanding of the potential implications for future roof maintenance and replacement.

However, it's essential to carefully assess the condition of your existing roof and consult with professionals to determine the most suitable approach for your home. By making an informed decision, you can ensure that your roof upgrade contributes to the long-term value and comfort of your home.
