Metal Roofing Over Asphalt Shingles

Yes, metal roofing can, in fact, be installed over existing asphalt shingles. This is a viable option for homeowners who wish to bypass the costs and inconvenience associated with the removal of an old roof before installing a new one. This technique, known as “roof over,” takes advantage of the existing shingles as a supportive base, aiding the installation of the new metal roof. It’s an approach that can be both efficient and cost-effective, but it’s essential to understand the correct procedures and potential challenges to ensure a successful installation.

How the Installation Works

Installing a metal roof over existing asphalt shingles begins with assessing the current roof’s condition. Any damaged or loose shingles should be repaired or secured to create a solid base. Next, a layer of insulation or underlayment is typically installed over the shingles to provide additional support and prevent moisture from entering the building. The metal roofing panels are then laid directly over this layer. They are securely fastened using special metal screws that penetrate through the metal and insulation into the existing asphalt shingles. This process helps create a tight seal, ensuring the stability and durability of the new roof. However, it’s crucial to have a professional roofer or an experienced contractor carry out the installation to ensure it is done correctly and safely.

When To Consider This Technique

There are a few scenarios where installing metal roofing over existing asphalt shingles may be the optimal choice. A roof over can be a practical and cost-effective solution if the existing roof is in relatively good condition with minimal damage or sagging. This technique is also worth considering when removing and disposing of old roofing material is costly or logistically challenging. Furthermore, if time is of the essence, installing a metal roof over existing shingles can save substantial time compared to a full tear-off and rebuild. Nevertheless, it’s vital to consult a roofing professional to assess the condition of your current roof and determine whether this technique is suitable for your specific situation.

Now that you have an overview of installing metal roofing over asphalt shingles, you can determine if this is the right choice for your home. While this method offers potential cost savings and efficiency, it’s crucial to assess the state of your current roof and consult a professional to ensure a successful installation.
