Can I Put a Metal Roof Over Shingles?

Do you have an older shingle roof that you’re thinking of upgrading to something more long-term and durable? If so, you’re in the right place! Van Martin Roofing is here to help!

In our decades of roofing experience in the Miami Valley Ohio area, we often come across homeowners who are considering upgrading their roof. Some customers will ask us if they can put a metal roof over shingles. This inquiry is more common than you may think, especially given the incredible benefits of metal roofing. In the following blog, we will explore whether installing a metal roof over existing shingles is a viable option. We will also look at what advantages this method offers, potential issues to consider, and key points to remember before proceeding.

So, without further ado, let’s look at the benefits of putting a metal roof on top of shingles.

Benefits of Installing a Metal Roof over Shingles

Installing a metal roof over your existing shingle roof can offer a wide range of benefits. For starters, one of the most significant advantages is the cost in savings. Since you won’t have to tear off the old shingles, you save on labor and disposal costs, making it a more economical option. Additionally, metal roofs are known for their durability and longevity, often lasting 40 to 70 years compared to the shorter lifespan on shingle roofs, which is usually between 20 and 30 years.

In short, this means fewer replacements and less maintenance over time because metal roofs are more durable.

Another benefit is their energy efficiency. Metal roofs reflect solar radiant heat, reducing cooling costs by up to 25 percent during the hot months of summer — a considerable benefit for homeowners in Greater Dayton. Last but not least, metal roofs provide a sleek, modern aesthetic that can enhance your home’s curb appeal and potentially increase its market value.

The Problem with a Metal Roof Over Shingles

Although there are numerous benefits to installing a metal roof over shingles, there are also potential drawbacks that need to be addressed. One of the primary concerns is the condition of the existing shingle roof. If the underlying shingles are damaged or have structural issues, these problems may compromise the integrity of the new metal roof. It is essential to ensure that the existing roof is in good condition before considering an overlay.

Another issue to consider is the added weight of putting metal over an older roof. Although metal roofs are generally lighter than traditional roofing materials, installing them over an already existing shingle roof will put extra weight on the overall roof structure, which could be near its limit. This can put stress on the underlying roof deck and framing. It can cause damage over time. Because of this, consulting a professional roofer like Van Martin Roofing is essential to assess whether your home’s roof structure can handle the additional weight.

Additionally, improper installation of a metal roof over shingles can lead to moisture buildup and mold growth between the layers. This can cause long-term damage and decrease the lifespan of both roofs. Proper ventilation and installation techniques are essential to prevent these types of problems.

Key Things to Remember Before Installation

Before deciding to install a metal roof over shingle roofing, there are several key points to consider. First and foremost, you should check local building codes and regulations in Greater Dayton. Some areas may have restrictions or specific guidelines regarding roof overlays, so it’s essential to ensure compliance. At Van Martin, we handle this for you.

Secondly, we should also inspect the existing shingle roof thoroughly. We check for signs of damage – this includes things like leaks, soft spots, or missing shingles. We address any issues before proceeding with the metal roof installation to avoid future complications.

This underscores the importance of choosing a reputable and experienced roofing contractor. Proper installation is essential for the performance and longevity of your metal roof. A professional roofer like Van Martin will always ensure that the installation meets industry standards and is done correctly and by the book.

Last but not least, we also help you consider the type of metal roofing material and design that best suits your home. Metal roofs come in a wide range of styles, including standing seam, corrugated panels, and metal shingles. Each type has its own set of benefits and aesthetic appeal. We recommend you select one that complements your home’s architecture and meets your functional requirements.

In Conclusion . . .

In summary, you can safely install a metal roof over shingles. However, it is essential to weigh the pros and cons carefully. Although cost savings, durability, and energy efficiency are significant benefits, ensuring the existing roof’s condition, addressing weight concerns, and preventing moisture issues are essential steps before proceeding.

By following these guidelines and consulting with a professional roofer like Van Martin, you can make an informed decision that enhances the longevity and performance of your roof.
