Are you worried about spending extra time and money on removing those old shingles before installing metal roofing? Well, the good news for you is, that you might not have to! Installing metal roofing over shingles is a common and cost-effective solution if you’re looking to enhance your roof without the need for a complete roof replacement. However, there are some important factors you need to consider for making an informed decision.
In this blog post, we’ll explain whether you can install metal roofing over shingles, things you should know, and the benefits of metal roofing over shingles.
Is It Possible to Install Metal Roofing Over Shingles?
Yes, you can install metal roofing over a roof made of shingles. This approach is not only possible but increasingly popular because it saves time and cost, as you don’t need to remove the old roof.
Most of the building codes and regulations also allow this installation if your home structure is strong enough to support the weight of an additional layer of roofing. However, you must check your local regulations and consult with a professional roofing contractor before you proceed with this installation.
What to Consider Before Installing Metal Roofing Over Shingles
Metal roofing installation over shingles can be a good idea but you need to consider some factors before you make that decision. Some of these important factors are:
- Building Structure
When you’re placing a metal roof above an existing shingles roof, you’re putting extra weight on the building structure. A professional roofing contractor can help you evaluate if your home can support that extra weight.
- Condition of Existing Roof
If the shingle roof is in bad condition, you need to check it for any issues like damage or leaks. A new roof over a compromised and old one might lead to more issues down the line.
- Ventilation
You need to make sure there is enough ventilation to prevent moisture buildup between the layers of shingles and the new metal roof. If there is enough moisture, mold can grow between the two roofings and cause damage to your home’s structure.
- Building Codes and Permits
While most areas allow up to two layers of roofing, some places might need you to obtain some permits or get an inspection by a certified roofing contractor before you continue. Be sure you’re following all the building regulations and local laws before any construction.
- Underlayment
Consider using a quality underlayment to prevent corrosion and provide extra insulation. A good underlayment between the metal roof and the shingles can help manage moisture and improve the life of your new roof.

Benefits of Metal Roofing Over Shingles
Metal roofing can have many benefits that make it a good choice to be installed over shingles as a second layer. Here are some of the most important benefits you should know about:
- Durability
You don’t install a new roof every other day, do you? That’s why you need to choose the one which is durable enough to last years. Metal roofing can last for even 40 to 70 years depending on your local climate, while traditional shingles last only 12 to 20 years. Metal roofs are very resistant to harsh weather like high winds, heavy snow or heavy rain, which makes it a good long-term investment as you won’t have to spend much on repairs or replacements.
- Energy Efficiency
Most roofs can reflect sunlight which makes your home cooler in summers and reduces the cooling costs. A layer of metal over shingles means there are two insulating layers, and the air cushion between them can offer additional insulation. It makes your home more energy efficient as temperature regulation might become much easier.
Lightweight and Structural Benefits
Metal roofing is mostly a lot lighter than shingles. It means your home structure won’t have to bear much additional weight after a metal roof is installed over the shingles.
- Aesthetic Appeal
Metal roofing is available in various colours and styles, making it easier to make your home look the way you want without any extra costs.
- Cost-effective Option
Installing metal roofing over the shingles is very economical as you won’t have to remove the old roof. This will be lighter on your pocket as you can save money on labour and disposal costs.
