Stay Cool | The Best Roofing Materials for Hot Weather

Print/Save as PDF

If you landed here I can only assume that you also live down here in the south where we see these triple-digit temperatures all too often.

 

Most folks only worry about the air conditioner functioning at peak performance and never really consider how important it is to have a roof that can handle this sweltering heat too.

 

Being a roofing contractor here in the south for nearly 3 decades, it’s fascinating just how many homeowners will choose the least expensive roofing materials without researching or ever considering how often they will need to replace those cheaper roofing materials because the sun has literally cooked them within 10 to 15 years. 

 

And I get it, most of us don’t plan to replace our roofs, right? We spring a leak and then a full roof replacement is literally sprung on us (pun intended) when our local roofing contractor delivers us with the bad news.

 

“I’m sorry, but your roof is not repairable.” 

 

So here at RoofCrafters Roofing, we want to help our community by sharing our 29 years of experience by helping educate the people in our community so that you can make a well-informed decision about your upcoming roof replacement project. 

 

We know from experience that it will beat being reactive and therefore by default choosing the cheapest roofing materials for your home.

 

We also know what happens with the grueling fireball in the sky bearing down on cheap roofing materials.

 

So in this article, you are going to learn the best roofing materials for extremely hot weather conditions along with the average cost for each of these materials.

 

All of the roofing materials we discuss will perform extremely well in triple-digit weather conditions, and more importantly won't need to be replaced every 10 to 15 years, making them a great investment for you if you decide to go with one of them.

 

I am excited to share, so let’s dive right in!



The 5 best roofing materials for extremely hot weather

 

The following 5 roofing materials are for steep-slope roof applications, I will also provide the average square foot price for these 5 roofing materials  that will best endure the extreme heat.

 

  1. Metal roofing
  2. Slate roofing
  3. Clay tile roofing
  4. Concrete tile roofing
  5. Synthetic roofing


1. Metal roofing

 

Metal roofing will excel and perform extremely well in all hot weather climates. They are highly reflective and with the right color paint finish are energy efficient. The sun will not break the metal down.

 

There are 2 main types of metal roof systems:

 

  • Standing seam
  • Screw-down

 

Standing seam is a concealed fastener metal roof system and screw-down is a metal roof with an exposed fastener through the metal roofing. Both metal roof systems have their own advantages and disadvantages. 

 

The advantages of the standing seam are their longevity, properly installed they will easily last for 50+ years, they provide a very high wind rating, the highest in our industry, they don't blow off in wind storms, they handle the extreme heat, and add value to almost any structure. 

 

The disadvantages are the upfront investment. They do cost more because the attachment method takes longer for your roofing contractor to install and requires a much higher skill level to properly install the flashings and other metal components that make up a metal roof system.

 

The advantages of the screw-down roof are that they are the most economical and easiest for your roofing contractor to install. They perform extremely well in high winds, so they will not blow off during a high wind event.

 

Their disadvantage is that they require maintenance within the 5-year mark. With all the thermal movement (expansion and contraction) that happens with  metal roofing, the exposed screws can start to come loose. And they do in time.

 

There are 3 metal roof materials that are most commonly installed in the US over the past 30+ years:

 

  • Aluminum 
  • Steel
  • Galvalume

 

These 3 metal roofs are the most economical and cost-effective. They offer a wide range of aesthetic looks, longevity, and price ranges. 

 

All of these metal roofing materials are available in a standing seam metal, screw-down, and even a shingle-style profile.



Aluminum metal roofing



Aluminum is one of our most natural energy-efficient metal roof materials available. Aluminum metal comes in different thicknesses and typically for roofing we use a 032, 040, or 050 thickness. The higher the number is, the thicker the aluminum roofing. The 032 and 040 thicknesses are most popular on residential and commercial roofs. 

 

Aluminum comes in a mill finish(raw metal) or a painted finish. Mill finish will provide you with a raw metal look and it will oxidize into a naturally beautiful raw metal finish. Aluminum comes in a wide variety of painted finished colors. Most of the paint finishes come with a 40-year paint warranty with some manufacturers even providing a 45-year paint finish warranty. We recommend and only use aluminum for our clients that live on or within a mile of the saltwater. 



Steel metal roof 



Steel roofing is the most popular metal roofing material used for roofing on residential and commercial buildings. Steel metal is galvanized steel that is hot dipped or coated in a zinc coating. Steel is less costly and can be as effective and efficient as any of the other metal materials that are available. 

 

The steel commonly used for roofing comes in 24 gauge, 26 gauge, and 29 gauge. Don't get fooled, unlike aluminum, the lower the number the thicker the steel roofing will be. 

 

4 of the most common steel roofing profile that is installed on residential and commercial properties:

 

  1. Standing seam metal panels (12”-18” wide panels, concealed fasteners)
  2. Interlocking steel shingles  (slate or shake look, concealed fasteners)
  3. 5-V crimp metal roofing (2-foot wide panels, exposed fasteners)
  4. R-panels or multi-rib panels (3-foot wide panels, exposed fasteners)

 

Because steel is not a non-corrosive metal, these metal roofing materials require a painted finish. Paint finish warranties range from 20 years to 45 years depending on the thickness, type of panel, and the manufacturer of the metal and paint.

 

Steel metal roofing is very cost-effective and offers a wider range of prices depending on which profile you choose, the thickness of the metal, and the paint warranty. 



Galvalume metal roof

 

Galvalume metal is also a metal that has a steel core and is coated with aluminum to prevent corrosion. 

 

Galvalume is much like steel roofing and comes in the same thicknesses, 24 gauge, 26 gauge, or 29 gauge. It is also available in all 4 of the different panel profiles. 

 

The main difference with galvalume is that it comes as a mill finish metal product, so it is not available in a painted finish. This makes it slightly less expensive and easier to work with as the painted materials can get scratched during installation if not handled carefully. It is also a great option to use around the ocean or if you live anywhere near the saltwater.

 

The price of these metal roofing options ranges from $7.50 a square foot to $15.50 depending on the metal type, paint finish, and complexity of the job.

 

2. Slate roofing

Slate roofing is a natural stone cut from a slate quarry. Slate is fireproof and impervious to the weather making it an excellent option for extreme hot climate regions. Slate is also good for cold weather conditions. 

 

Slate roofing can be an excellent investment for your property because installed properly you can expect to get 100+ years from a slate roof system. Because slate is a natural stone the average weight of a slate roof is 1000+ pounds per square foot. So, before deciding on a slate roof I recommend consulting with your roofing contractor or an architect to ensure that your property is built to support the weight.

 

Slate roofing is also one of the most expensive roofing products to buy and to have installed as it requires a special skill set that not many roofers have.

 

The cost of slate roofing ranges between $15.50 and $25.50 per square foot depending on the type, color(very important), and complexity of the project.

 


3. Clay Tile

Clay tiles are sometimes referred to as a Spanish roof or a Spanish tile roof and are one of the premium natural roofing materials that are designed for longevity and to appeal to a certain architectural design. 

 

Typically clay tile roofing is installed on Mediterranean, European, Modern, and of course Spanish style homes. With multiple colors and styles to choose from, they will provide you with a unique one-of-a-kind roof. 

 

The average price of a clay tile roof ranges from $12.50 to $18.50 depending on the style, color, and complexity of the roof.

 

 

 

4. Concrete tile roofing

When it comes to concrete tiles, no material is more versatile. Concrete tiles can even match the look of cedar shakes, slate roofs, and clay tiles. They come in a variety of styles and colors to choose from, Known as profiles.

 

The cost of a concrete tile roof system will range anywhere from $9.50 to $13.50 per square foot depending on the profile you select and the complexity of your roof.

 

 

5. Synthetic roofing

 

synthetic roofingMost manufacturers of synthetic roofing provide both a slate roof and a wood shake roof profile. Typically synthetic roofing materials are made from affordable recycled materials such as rubber and plastics. Some are also made from engineered polymers. 

 

Rubber is well known for its insulating capabilities which helps to make synthetic roofing more energy efficient in hot weather.

 

Because of their durability and longevity synthetic roofing products are great alternative roofing materials to choose for any extremely hot climate region.

 

The average cost of a synthetic roof ranges between $12.50 and $18.50 per square foot depending on the style or color you choose and the overall complexity of your roof.
