Best Roof Tiles for Hot Weather

What is the role of roof tiles in hot weather? Imagine sitting in your house in summer that its rooftop not only does not transfer the outside heat to the inside; but also minimizes your home’s energy consumption. Do you know that roof tiles are 70 – 80% effective in preventing heat from entering the building? That is how important they are for hot climates.

Best Roof Tiles for Hot Weather

Whether you are living in a desert climate that is always dry and scorching or experience seasonal heat in your city; we are here to introduce you the best roof tiles for hot weather.

We will also discuss other factors that play important roles to reduce heat and make roofs cool.

What are the specifications of roof tiles resistant to heat?

Thermal insulation:

In order not to transfer cold in winter and reduce heat in summer, insulation is used in the underlayment of roofs. However roof tiles are best only when they keep the roof cool in hot weather without the need for installing insulation in attic or additional infrastructure costs. This is what uPVC roof tiles do to keep the interior environment of the roof cool. (More details at the end of the article).

 

 

Cost of roof tiles in hot weather

Some roof tiles do not need a special underlayment for insulation. Instead, installing panels on other roofs might cost you a lot. An optimal roof tile should be able to prevent heat and cold from entering and also leaving the building at a minimum cost. And this means easy installation, high durability and low cost of best roof tiles in hot weather.

 

Resistant to UV light

What will happen if the roof material do not have protective and anti-UV coating in hot weather? Or have little resistance to sunlight? More than just a faded color of tiles. Due to not repelling light and heat, crack and significant damage will happen over time.

There may be other options in the list of the best roof tiles in hot weather, but here we will only mention the most effective ones.

Clays (Glazed Clay roof tiles)

 

Clays (Glazed Clay roof tiles)

Although clays are heavy tiles, but they are durable and resistant to UV. Curved shape of clay tiles allow air to circulate under the roof, and make it cool. That is why clay roof tiles are good option in hot weather. However there are some drawbacks you need to pay attention before buying clay tiles. For more beauty and not absorbing moisture, you can use glazed clay roof tiles.

Due to its heavy load, the infrastructure of the roof needs to be reinforced. Clay roof tiles are expensive and can become brittle. UPVC materials are better alternatives to clay roof tiles in hot climate.

Heat transfer coefficient of uPVC tiles are 1/3 clay roof tiles. The heat transfer coefficient indicates the amount of hot air entering and leaving the roof of your building. The lower it is, the more optimal roof tiles are and more energy will be saved which lower your electric bill.

 

 

 

 

Concrete roof tiles in hot weather

Concrete roof tiles are another good option for hot weather. It costs less than clay tiles. Thickness of concrete can slower the process of absorbing heat. Hence the roof can keep the cold for longer period of time.

 

Due to water absorption, concrete roofing requires frequent maintenance. Being brittle and heavy weight can be other drawbacks since the installation and walking on them will not be easy.

In uPVC roof tiles you will not have these problems, as they are lightweight and easy to install. Heat transfer coefficient of uPVC tiles are 1/5 cement and concrete roof tiles. Hence upvc is a better material to keep the roof tiles cool in hot weather.

UPVC roof tilesUPVC roof tiles

UPVC flat and trapezoidal panels are widely used for both external and internal covering of roofs and walls.

These roofs are used in all kinds of industrial sheds, residential and industrial complexes. Due to the protective polyurethane coating and sealing of the sheets, they are called cooling roof tiles in hot weather and waterproof sheets in the cold.

Due to the high strength of the sheets, the distance of purlins are wider. As a result, the infrastructure cost is reduced and construction price becomes cheaper. UPVC sheets do not need common or traditional thermal insulation materials such as glass wool and rock wool. Its 2 mm thick sheet keeps the roof at least 10 degrees cooler. That is why they are one of the best roof tiles in hot weather.

Are metal roof tiles a good option in hot climate?

Metals are good conductors of heat. Metal roofs are no exception. Therefore, Heat can easily be transferred under the roof. On the other hand, they expand and contract due to temperature changes and provide space between the tiles to create moisture. That leads to corrosion and rust especially in humid areas.

What is the best roof tile color for hot weather?

Whether you are living in hot and humid or hot and dry (desert) climate; lighter color tiles will reflect 70% to 90% of sun rays from the rooftop and keep it cool.

Due to more heat reflection of the sun rays, the best color for roof tiles in heat is white – Especially milky and white color are recommended for roof coatings in hot weather.

 

Are metal roof tiles a good option in hot climate?

 

On the contrary Buildings with dark roof tiles absorb about 70-90% of the sunlight. Therefore, it is necessary to choose light color roof coverings to prevent heat as much as possible.

UPVC roof tiles in Sepidfam Varna are manufactured with light and bright colors. The sheet is flexible (curved roof construction) and a great barrier to UV rays in hot places.

What is the best roof shape to reduce heat?

So far we know which type of roof tiles and what colors are best in hot weather. But now we want to see what roof shapes have to do with heat absorption and sunlight reflection. Also which roof shape can reduce heat in warm weather?

 

What is the best roof shape to reduce heat?

Flat roofs are constantly exposed to sunlight, but domed and sloping roofs are more likely to reflect sunlight due to the protrusions and angles of the roof. Also, better ventilation in domed and gable roofs, is an important factor for cooling the roof tiles in hot weather. Hence they are more energy-efficient than the flat roofs.

Considering what has been said above, an ideal option in this case is choosing UPVC gable roof tiles in hot weather.

 

 

 

 

Which roof tile is more resistant to hot weather?

 

Hot weather is not only associated with dryness. In many parts of the world, the weather is hot and humid. Salt storms and hurricanes are no exception. Rain and humidity make us pay more attention to choose better roof tiles, underlayment and insulation.

UPVC roof tiles in Sepidfam Varna Company are easy to transfer and install due to their light weight and high durability. These roof tiles do not require any additional insulation in hot climate. That is because the type of material and the way it is optimally overlapped. So it will protect and seal the roof against heat and cold.

FAQs

 

What are the most important factors to keep roofs as cool as possible?

Shape, color and material of the roof tiles play an important role in reducing the heat under the roof.

 

Why uPVC is a better covering in hot climate than metal roof tiles?

No expansion of sheets and low transmission coefficient of heat are the most important features of uPVC roof tiles in hot weather. Thermal conductivity of uPVC panels are 0.325w/mk which is 1/2000 of color coated metal sheets with half a millimeter thickness.

 

 

What colors are best for roof tiles in hot weather?

Due to more heat reflection of the sunlight on the roof; lighter color sheets make roofs cooler up to 90%. Hence to save more energy and money, white color is recommended for roofing in hot climate.
