Why Installing a Metal Roof Over Existing Shingle Roofs is a Smart Choice

When it comes to upgrading your roof, metal roofing is becoming an increasingly popular choice for homeowners. One common question we hear at ProSource Roofing & Renovation is whether a metal roof can be installed over an existing shingle roof. The answer is yes! Not only is this possible, but it’s also often a cost-effective and efficient solution. Let’s explore the benefits and considerations of installing a metal roof over shingles.

Why Choose a Metal Roof?

Metal roofs offer numerous advantages, including:

• Durability: Metal roofs can last 40-70 years, outlasting traditional shingles by decades.

• Energy Efficiency: Reflective coatings help reduce cooling costs by reflecting solar heat.

• Low Maintenance: Metal roofs require minimal upkeep, making them a long-term, worry-free investment.

• Weather Resistance: They’re built to withstand harsh weather, including high winds, heavy rain, and hail.

• Aesthetic Appeal: With a variety of styles and colors, metal roofs can enhance your home’s curb appeal.

Benefits of Installing Metal Over Shingles

1. Cost Savings

   • Removing an old shingle roof can be labor-intensive and expensive. By installing metal over shingles, you save on tear-off and disposal costs.

2. Faster Installation

   • Without the need for a full roof removal, installation is quicker, minimizing disruption to your daily life.

3. Added Insulation

   • The layer of shingles beneath the metal roof can act as an additional insulating barrier, improving your home’s energy efficiency.

4. Environmentally Friendly

   • By avoiding the removal and disposal of old shingles, you reduce landfill waste. Plus, metal roofing is often made from recyclable materials.

How It’s Done

Installing a metal roof over shingles involves several steps to ensure a secure and long-lasting result:

1. Inspection: A thorough assessment of the existing roof is crucial to ensure it’s in good enough condition to support the new metal roof.

2. Underlayment: A high-quality underlayment is installed over the shingles to create a protective barrier against moisture.

3. Purlins (Optional): In some cases, purlins are added to create a flat surface and allow ventilation beneath the metal roof.

4. Metal Roof Installation: The metal panels are carefully installed, ensuring proper alignment and secure fastening.

Considerations to Keep in Mind

• Building Codes: Check local building codes to ensure layering roofs is permitted in your area.

• Roof Condition: If the existing shingle roof has significant damage or structural issues, it may need to be repaired or removed first.

• Weight Concerns: While metal roofs are lightweight, it’s essential to confirm the structure can handle the combined weight of the shingles and metal.
