Can You Put a Metal Roof Over Shingles? Addressing Common Concerns
When it's time to replace your aging roof, many Atlanta homeowners wonder: "Can you put a metal roof over shingles?" At ARAC Roof It Forward, we frequently receive this question, and the short answer is yes; in many cases, you can install a metal roof over existing shingles.
However, this decision involves several important considerations to ensure a successful installation and the long-term health of your existing structure. Let's address the common concerns about installing metal panels directly over your current shingles.
Is It Structurally Sound to Install a Metal Roof Over Existing Shingles?
One of the primary concerns homeowners have is whether their home can support the additional weight of a new metal roof on top of their old shingle roof. While modern metal roofing materials are surprisingly lightweight compared to traditional materials, the combined weight of metal roof panels plus existing shingles can create structural concerns.
Before proceeding with a metal roof-over, ARAC Roof It Forward conducts a thorough inspection of your roof deck and wooden boards to verify the structural integrity of your home. We inspect for signs of water damage, insect infestations, or severe damage that could compromise your roof's integrity. This assessment helps prevent bigger problems in the long run.
Additionally, Atlanta's local building codes may have specific requirements regarding the number of roofing layers permitted on a residential structure. Some areas limit homes to two layers of shingles, while others may require a complete tear-off if specific conditions are met.
Potential Problems with Installing Metal Over Shingles
Uneven Surfaces and Installation Challenges
Your old roof likely has developed some irregularities over time. When installing a new material over an asphalt shingle roof, these uneven surfaces can pose challenges. Professional roofers use specialized techniques to create a smooth surface for your metal roofing system, ensuring proper attachment and minimizing potential issues.
Moisture Concerns and Ventilation
A significant concern with installing a metal roof over shingles is moisture buildup. Without proper and adequate ventilation, condensation can form between your current shingles and the metal surface, potentially leading to mold growth and deterioration of your existing roof structure.
ARAC Roof It Forward addresses this by implementing ventilation solutions that ensure proper airflow throughout your shingle roofing system and the new metal roofing system. This attention to detail helps maintain your roof's performance even during Atlanta's high humidity conditions.
Weather Resistance Considerations
Atlanta experiences a range of weather conditions throughout the year, from heavy rain and high winds to occasional extreme weather conditions. A well-installed metal roof provides excellent protection against these elements, but installation over old shingles requires special attention to ensure the metal roof panels can withstand these challenges.
Our standing seam metal roof installations are specifically designed to handle Georgia's harsh weather conditions and even offer improved resistance to lightning strikes and strong winds compared to traditional asphalt shingles.
Benefits of Installing a Metal Roof Over Shingles
Cost and Time Savings
One of the most appealing aspects of a metal roof-over is the potential for significant cost savings. By avoiding the removal of your existing shingle roof, you can reduce labor costs and disposal costs associated with a complete tear-off. This approach is often more economical in the long run while still providing the exceptional benefits of a new roofing system.
Environmental Impact
Keeping your old shingles in place rather than sending them to a landfill reduces the environmental impact of your roofing project. Metal itself is an eco-friendly choice, as it's often made from recycled materials and is fully recyclable at the end of its long life.
Energy Efficiency Benefits
Metal reflects the sun's rays rather than absorbing them like traditional asphalt shingles. This reflective property can significantly improve your home's energy efficiency, potentially reducing cooling costs during Atlanta's hot summers. Many of our clients report noticeable savings on their energy bills after upgrading to a new metal roof.
Enhanced Aesthetic Appeal and Value
The sleek appearance of metal roofs can dramatically enhance your home's curb appeal. Available in various styles and colors, metal roofing materials can complement virtually any architectural design while providing exceptional durability and minimal maintenance requirements.
