Does a Silver Metal Roof Reflect Heat?

If you are considering a metal roof for your home, you’ve probably heard that silver metal roofs provide a great way to reflect heat. That’s true, but there’s more to consider than just the color of the roof.

You need to consider the type of metal used, how the roof is installed, and even the orientation of your house when wondering if a silver metal roof will reflect heat.

In this article, I will answer the question, “does a silver metal roof reflect heat” and also break down exactly how it works. 

So let’s dive in and discuss how a silver metal roof can help keep you cool this summer.

Does a Silver Metal Roof Reflect Heat

Have you considered a metal roof for your home, but you’re wondering whether the silver color can help keep your house cooler? The answer is yes! Silver metal roofs effectively reflect heat from the sun, keeping your house cooler in the hot summer months.

If you’ve ever noticed that a lot of buildings and houses in hot climate areas tend to have silver roofs, that is why,  

Silver metal roofs (often called “ash gray”) are great at reflecting the sun’s heat, meaning that they can lower your home’s summer temperatures and help you save on energy bills.

Silver metal roofing has been around since the 1950s and is one of the most popular roof types in warmer climates. 

It reflects the sun’s heat rather than absorb and trap it like darker colored materials, creating a cooler atmosphere within your home and reducing any air conditioning needs. 

A silver metal roof is also much more durable than traditional asphalt shingles, making it resistant to deterioration from UV rays as well as hail, wind, and extreme temperatures. 

In addition to its cool temperature benefits, it also offers other advantages such as high reflectivity for solar panels in order to maximize energy savings.

So if you live in an area with hot summers, or if you want to reduce your energy bills without sacrificing style or durability—consider installing a silver metal roof!

What is the Advantage of a Silver Metal Roof in Reflecting Heat?

Silver-colored roofs are made of metal— usually aluminum or steel — with a thin layer of a heat-reflecting coating. This coating helps reflect up to 70% of the sun’s rays away from your house, making it noticeably cooler on hot summer days. 

That’s in contrast to darker colors like black or dark gray. These absorb more than 60% of the sun’s energy and radiate it back into your home, resulting in much higher temperatures indoors!

When selecting a silver metal roof for heat reflection, it’s important to look for one graded as Energy Star-rated or Cool Roof-certified. 

This means that the roof has been tested and shown to be an effective reflector of both visible and infrared light from the sun, reducing cooling costs and keeping your home at a more comfortable temperature.

How to Select the Best Silver Metal Roof for Reflecting Heat

When selecting a silver metal roof for heat reflection, there are several things you should consider.

Material Composition

First, look at the material composition of the silver metal roofing. Generally, aluminum is the best choice when it comes to reflecting heat away from your home as it is considered one of the best heat-reflecting materials available and comes in a range of finishes and colors. 

Additionally, aluminum has the highest recycled content of any other metal roofing material, making it one of the most environmentally friendly options as well.

Paint Finish

Second, consider the paint finish of your silver metal roof. If you want maximum heat reflection, choose a paint finish with a Kynar 500 or Hylar 5000 pigment as this will ensure that your roof has maximum reflectivity and durability. 

Additionally, these pigments are fade-resistant so your roof will maintain its desired color for years to come.

Thermal Mass

Finally, look for a silver metal roof with a high thermal mass rating which measures how well the material retains and releases heat. 

The higher the thermal mass rating, the better it is at reflecting heat away from your home while still maintaining its functionality in colder climates.

When looking for a silver metal roof that reflects heat effectively and efficiently, take into account these materials so you can make an informed decision that will benefit both you and your home in the long run.

Underlayment Considerations for a Silver Metal Roof

Did you know that what’s underneath your silver metal roof could play a big role in its effectiveness at reflecting heat? 

It turns out that the type of underlayment, or material placed between the roofing panels and your home, matters when it comes to keeping temperatures down.

Underlayment options might include:

  1. Asphalt felt (a black mat)
  2. A reflective barrier (white foil insulation)
  3. Synthetic underlayment (another insulation option)
  4. Radiant heat barriers (made of aluminum or foil-faced fiberboard)

In general, a silver metal roof with a white reflective or aluminum radiant barrier performs best at reducing the amount of heat that is conducted from your roof into your home. 

If you choose an asphalt felt option, be aware that this may absorb more heat, leading to higher temperatures inside your house and increased energy costs due to increased air conditioning usage.

So if you are considering a silver metal roof for your home, think about what kind of underlayment you’ll use: make sure it can help contribute to the temperature control abilities of the roof.

Benefits of Painting a Silver Metal Roof

A silver metal roof is an excellent choice if you’re looking to reflect the sun’s heat, and it can also bring some other great benefits.

For one thing, a silver roof reflects more of the sun’s UV rays than any other material, which means your house will stay cooler and your air conditioning costs will go down. 

Plus, painting a silver metal roof also gives it a great and stylish look — just make sure to use high-quality paint suitable for outdoor use.

Costs Less Than Other Alternatives

Paint is of course cheaper than some of the other alternatives for reflecting heat from a roof — so you don’t have to break the bank to get a reflective roof. 

Plus, painting your roof means you won’t have to replace it after a few years if you want to change up its color — just paint it again!

Long Lasting

By using quality paint that is designed to withstand harsh weather conditions, when you paint your silver metal roof it can last up to 15 years without needing another coat of paint. That’s obviously going to save you money in the long run.

Painting your silver metal roof has two main advantages: It reflects heat better than other materials and it is cost-effective. 

With quality painting materials and some regular maintenance, you can enjoy all the benefits of this highly efficient heat-reflective solution for many years!

Different Varieties of Silver Metal Roofs

You might know that a silver metal roof can reflect heat, but did you know there are actually different varieties of silver metal roofs?

Galvalume Steel

The most common type is a Galvalume steel roof. Galvalume steel is composed of aluminum, zinc and other materials that help make it able to reflect up to 85 percent of the sun’s rays, reducing heat absorption and providing an attractive finish. 

It’s also rust-resistant, making it a great choice for roofs with large surface areas because it requires minimal maintenance.


Aluminum roofing also reflects a good portion of the sun’s rays, up to 80 percent. Aluminum has natural anti-rusting properties, and its lighter weight makes installation relatively easy. This makes aluminum an ideal choice for residential roofs.

Zinc & Copper

Finally, zinc and copper are the two most reflective metals for roofs — both reflect about 95 percent of the sun’s rays — but they come with a hefty price tag. 

Copper is more expensive than zinc but can last longer in certain climates, while zinc is a more affordable option that’s also resistant to corrosion-causing elements like humid air or chloride salts.

When considering silver metal roofs, it’s important to take into account the variety (what material it is made from) as well as its reflective strength (how good a job it will do at reflecting heat). 

After all, different kinds of silver metal roofs come with different benefits – so do your research before you buy!


So, if you ever hear the question ‘does a silver metal roof reflect heat” just know that it sure does. A silver metal roof can reflect heat away from your home, making it cooler and reducing monthly energy costs. 

Depending on the type of metal used, it can be very durable and resilient, lasting up to 40 or 50 years with proper maintenance.

While a silver metal roof can be expensive upfront, the long-term savings and potential increase in home value make it a worthwhile investment. 

Plus, the conservation of energy makes it a good choice for those who are looking for a more environmentally-friendly solution to keeping their home cool.
