The short answer is yes, you can put a metal roof on top of shingles. There are some things to consider before deciding to install a new metal roof over your existing one. First, make sure that your home is structurally sound enough for additional weight. Secondly, keep in mind the different types of metal roofs and how they will be installed before deciding which type would best suit what you're looking for in terms of durability, aesthetics, and cost-effectiveness. The cost between various types of roofs can vary based on factors like how big it has to cover or what materials are being covered. Finally, decide whether or not an area that gets lots of sunlight should have a metal roof that reflects heat away or whether it would be better to have one with insulation.

Factors to Consider Before Installation

When deciding whether to put a metal roof over shingles, there are several factors to consider.

The structural soundness of the building

A metal roof can add a significant amount of weight to your home and might even alter its structural stability. Do some research on the structure of the house to make sure that it will be able to handle the additional weight and stress during a storm. You can also ask a contractor if they can make any renovations to the structure of your home before installing additional weight.

The type of metal roof there is available for you

Different types of metal roofs vary in their cost, durability, and insulation capabilities. Do some research on these various options before making a final decision about which one will be best for you. You should also consider where your home is located and if it will be better to have a metal roof that reflects heat away or one with insulation.

The cost of each metal roof

The cost of a metal roof will vary based on the size and how many materials you need. The type also affects the price, for example, steel roofs tend to be less expensive than aluminum ones. Take some time to research what kind of material will best fit your budget as well as which type is most durable if durability is a concern.

The availability of sunlight in the area you live

If there are lots of sunny areas on your property, then an aluminum roof would be best for reflecting heat away from those surfaces during summertime. If however, your property does not get much sun then it might be better to install an insulation roof.



Research the different types of metal roofs available and decide which one is best for you based on cost, durability, how big it will need to be, etc.

How to install a metal roof over existing shingles?

There are three different ways to install a metal roof. You can remove the old shingles completely, apply an approved underlayment right over the top of the existing roof, or install purlins across your current shingle roof.



Generally speaking, it is best to have a professional handle this job because there are specific procedures that need to be followed in each case.

1) Removing the old shingles

Removing the old shingles completely and starting from scratch is the best option if your existing plywood or boards underneath are in good condition. This way, when installing a new metal roof, it will be done correctly without having to worry about additional weight on any faulty or rotten boards.

2) Applying an underlayment

Applying an approved underlayment right over the old shingle roof is probably the fastest way to install a new metal roof, but it's also not recommended by most experts because this method could cause problems during heavy rains or storms if your plywood begins to deteriorate underneath.

3) Applying purlins

The best option for installing a metal is if your old shingle roof is in good condition and you would like to save money on labor costs, then applying purlins across your current shingles might be the way to go. However, this method of installation does not provide any benefits beyond aesthetics and cost-effectiveness so it lacks durability and performance capabilities that come with other options.

What benefits can you get from Installing a metal roof over shingles?

Installing a metal roof over your existing shingles is an excellent way to increase the value of your home, while also protecting it from common weather damage. A new metal roof can last up to 50 years without needing any roof replacement, which will save you money in the long run. Not only does this type of roof provide great protection against inclement weather, but they are also very energy efficient! This means that even though you may have spent more money on your initial installation, you will actually see a decrease in utility bills each month. Because these roofs are so durable and attractive looking, many homeowners choose to install them as well because they add value to their homes!

Some of the benefits include:

Aesthetic Appeal

Metal roofs can come in a variety and colors and provide additional insulation. They also tend to last longer than other types of roofing materials, such as asphalt shingles or wood shakes.

Durability

Metal roofs are typically very durable since they do not rot like cedar shakes or get damaged by hail like asphalt shingles. They are also stronger than other roof types and do not require much maintenance, which means you can put off repairs for longer without having to worry about leaks or damage.

Reduced Energy Costs

If you live in an area where it is hot during the summertime, then a metal roof will reflect the sun away from your home. This will help to reduce energy costs because it is less likely that you will need to turn on your air conditioning as much during the summer months.

Weather Resistance

Metal roofs are resistant to fire, wind, ice, and rain damage. This is a result of the durability that comes in metal roofing material choices such as steel or aluminum.

Value-Added Appeal

If you choose to sell your house in the future with a metal roof installed on it, then there is a good chance that you will receive more money because it will be in better condition than many of the other homes on your block.

Easy Maintenance

Metal roofs typically only require a simple wash down from time to time. This will help you save money on any professional roof cleaning services that may be necessary for other types of roofs.

How much does it cost to put a metal roof over shingles?

It is not cheap to replace a metal roof with existing shingles. The cost of putting a metal roof over an existing shingle roof will depend on the type of material you choose to use, but typically ranges from $4-$7 per square foot. This price includes the materials and installation.

The cost of a metal roof over shingles is more expensive than simply replacing the shingles. It’s important to note that putting a metal roof over existing shingles creates waterproof protection for your home, but it will not prevent leaks from coming through undiscovered damage or if water gets into the material beneath the new surface.

FAQs

Should you remove shingles before installing a metal roof?

Removing shingles can be an expensive process. If your roof is in good condition, then you may want to leave the existing materials in place and install a new metal roof over it instead. You will save money this way because you do not have to remove any material before installation begins!

How long does it take for a professional contractor to install a metal roof over shingles?

It typically takes about six days to complete the process of putting on a new metal roof. However, this will depend upon how many layers are in place and if you have already removed any old materials before installation begins. It is also worth noting that most homeowners wait several days between having their old surface removed and the new roof installed to ensure that everything is dried out appropriately.

Which is better a metal roof or shingles?

It all depends upon your needs and the environment you live in. If you want a roof that is long-lasting, then metal roofs are probably better for you than asphalt shingles because they last longer. However, if you do not have enough money to put towards new installation, but need some upgrades done quickly so leaks don’t become an issue, then shingles are better for you because they cost less and can be replaced easily.

Can metal roofs handle snow?

Yes! A new roof should never have to deal with too much snow during the winter which is why it's important to choose a material like steel or aluminum that is meant specifically for snowy climates. If you live in a region where it snows several feet each winter, then you will want to choose something that can handle the excess weight of all of the snow.

Can you put a metal roof over 3 layers of shingles?

Yes, you can install a new metal roof over three layers of shingles. However, you need to check with your contractor to see if there are any underlying issues that may lead to water damage or leaks later down the line. Additionally, you will need to check with them about how long it usually takes for roofing projects of this size and whether they have enough time in their schedule beforehand!

Are metal roofs louder than shingles?

No, metal roofs are not typically any louder than shingles. In fact, some homeowners have even noted that the addition of a new roof makes their home seem quieter because it does not allow as much outside noise to enter inside anymore!
