Can You Put Metal Roofing Over Shingles?
Chances are, you currently have a shingle roof and you are debating whether to make the switch to a metal roof. Did you know you do not have to remove your shingles to put on a metal roof? Our Multi-Rib panel gives you the option to apply directly over shingles, no tear-off required!
Determining if a Roof-Over is Right for You
You should have your roof inspected by a professional roofer to check for the following:
- Leaks or issues that need to be resolved
- Wood under the shingles is not rotted
- The condition of the shingles
- How many layers of roofing are already on your home
In addition to checking the condition on the current roof, you, or your roofer, should confirm with the county that more than one layer of roofing is permittable.
Why Should You Not Remove the Shingles?
- Leaving the shingles can result in a lower installation price, the contractor will not have to bill for the removal and disposal of the shingles.
- It is eco-friendly. You will not be adding shingles to the overflowing landfills.
- The shingles will act as an extra layer of protection. The shingles add another barrier between water and the decking.
Installation
There are two main methods when installing metal panels over shingles. The first is to apply an underlayment directly on top of the shingles. The new underlayment has two benefits: it is an extra barrier for any water that gets through the metal and it prevents the shingles from rubbing against the panels. Over time the granules from the shingles could imprint on the metal panels, the underlayment helps prevent any imprinting.
The other method is to install 1 x 4 purlins throughout the roof. The purlins allow for a flat surface for the metal panels. Shingles can create irregularities along the surface. The purlins also create an air space, which is great for insulation. Take advantage of the air space and add in rFOIL and block up to 97% of radiant heat transfer!

Overcoming Challenges Preserving Architectural Integrity : One of the main challenges in this transformation is ensuring that the new roof does not overshadow the home’s original architecture. This requires a careful balance between modern functionality and respect for historical aesthetics. Neighborhood Consistency : In areas where most homes reflect a certain era’s architecture, introducing a modern element like a metal roof can be contentious. It’s essential to consider the neighborhood's overall look and feel to ensure the update blends in harmoniously. Conclusion Transforming a 1950s home with modern standing seam panels is more than just an upgrade; it’s a marriage of history and modernity. This roofing choice offers a practical, efficient, and aesthetically pleasing solution, ensuring that the home not only retains its historical charm but also meets the demands of contemporary living. For homeowners in Florida, where the climate can be as challenging as it is varied, standing seam metal roofing is an investment in both the home’s future and its past. In embracing this transformation, homeowners are not only preserving a piece of history but also adapting it for a new generation, ensuring that these charming 1950s homes continue to be both relevant and functional in the modern world.
When it comes to installing a metal roof, the importance of choosing the right fasteners cannot be overstated. These small yet crucial components play a vital role in the overall performance, durability, and longevity of your roofing system. Selecting the appropriate fasteners for your metal roof involves understanding various factors, including the material, type, size, and environmental considerations. In this comprehensive guide, we will delve into these aspects to help you make an informed decision when selecting fasteners for your metal roof. Understanding Fastener Materials Galvanized Steel Galvanized steel fasteners are coated with a layer of zinc to prevent rust and corrosion. They are suitable for environments where moisture levels are moderate but are not recommended for coastal areas where the salt content in the air is high. Stainless Steel Stainless steel fasteners are more resistant to corrosion than galvanized steel, making them an excellent choice for coastal regions. They are more expensive but offer superior durability and a longer lifespan. Aluminum Aluminum fasteners are lightweight and resistant to corrosion, especially in alkaline environments. However, they are not as strong as steel and are not recommended for areas with heavy snowfall or high winds. Copper Copper fasteners are often used with copper roofs due to their compatibility. They offer excellent corrosion resistance and durability but are significantly more expensive. Types of Fasteners Screws Screws are the most common type of fastener used in metal roofing. They provide strong holding power and are available in various lengths and head types. Screws can be self-drilling, which means they have a drill point that eliminates the need for pre-drilling holes. Nails Nails are less commonly used in metal roofing due to their lower holding power compared to screws. However, they can be used in certain applications, such as attaching metal flashing or trim. Rivets Rivets are used in situations where a strong, permanent joint is required. They are especially useful in attaching metal panels to metal frames or in areas where access to the back of the panel is restricted. Selecting the Right Size and Length The size and length of the fasteners are critical factors in ensuring a secure metal roof installation. The length of the fastener should be chosen based on the thickness of the roofing material and any underlying materials such as insulation or wooden battens. Generally, the fastener should penetrate at least 1 inch into the purlin or support structure. The diameter of the fastener also matters, as a larger diameter provides greater holding strength. However, it should not be so large as to cause damage to the metal panels during installation. Environmental Considerations The environment where the roof will be installed plays a significant role in the choice of fasteners. Coastal areas, industrial environments, or regions with high humidity require fasteners with higher corrosion resistance. In such cases, stainless steel or specially coated fasteners are the best options. In areas with high wind speeds or frequent storms, fasteners with greater holding power and wind uplift resistance should be chosen to ensure the stability and integrity of the roofing system. Compatibility with Metal Panels The fastener material must be compatible with the material of the metal panels. Using incompatible materials can lead to galvanic corrosion, which occurs when two dissimilar metals are in contact in the presence of an electrolyte, such as water. For example, using copper fasteners on an aluminum roof can lead to corrosion of the aluminum panels. Aesthetic Considerations While functionality and performance are paramount, aesthetics also play a role in the selection of fasteners. Many fasteners come in a variety of colors, allowing them to blend seamlessly with the color of the metal panels. This creates a more visually appealing finish for the roof. Installation Techniques Proper installation of fasteners is as important as their selection. Fasteners should be installed perpendicular to the roof surface to ensure a watertight seal. Over-tightening can strip the fastener or deform the metal panel, while under-tightening can lead to leaks or wind uplift. Conclusion Selecting the right fasteners for your metal roof is a critical decision that impacts the performance, longevity, and appearance of your roof. By considering the material, type, size, environmental conditions, compatibility, and aesthetic preferences, you can ensure a secure and durable roofing system. Always consult with a professional roofing contractor to make the best choice for your specific roofing needs.
