Does a Metal Roof Make a House Hotter?

Many homeowners are concerned about the inside temperature of their house, especially the attic region when contemplating metal roofing. It is thought that since metal conducts heat, it must eventually result in a hotter dwelling during the summer. The rationale is sound, although incorrect. People mistakenly assume that since metal things left out in the sun get hot to the touch, a metal roof would create an uncomfortably heated attic area and house below it.

This is a completely untrue rumor. The fact is that metal roofing does not raise a home’s interior temperature and may even assist control a home’s temperature by keeping it cooler in the summer. Choose a reliable metal roofing company like LondonEcoMetal to get a high-quality cooling metal roof.

Metal roofs do not make homes any hotter than other types of roofs

No roofing system can keep your house cool in the summer, although most roofs will assist to keep out heat from direct sunshine. While it is true that metal roofs absorb heat, some of which may be transported into an attic living area below, this is true of any roof. When exposed to direct sunlight for extended periods of time, any dark-colored material, such as asphalt shingles, ceramic tiles, or wood, will absorb heat. Metal roofing is no exception.

How Metal Roofs Aid in House Cooling

Metal roofing, unlike other roofing materials, offers qualities that may assist decrease the surface and interior temperatures of a property.

Materials with greater weight and mass hold heat for a longer period of time. Metal roofing is one of the lightest and least thick roofing materials available, which means it will cool down faster after the sunsets.

Metal has a low thermal mass and reflects light, so it absorbs less heat during the day.

Lighter hues radiate heat rather than absorb it. Because metal roofs, unlike other roofing materials, may be coated in any color, you may pick a lighter tint to keep temperatures down.

What is the Big Deal About Cool Metal Roofs?

Many people misinterpret metal’s cool characteristics, believing that a metal roof is a heated surface, therefore how can it be cool? Several variables are at the action. However, the quality of your materials and workmanship will have a large impact on whether or not your metal roof provides the cool and energy-efficient features you want. To ensure that your roof operates optimally, deal with a reliable vendor and an experienced metal roofing contractor.


Did you ever climb on your asphalt roof as a child? If such is the case, you will recall how warm the roof felt long after the summer sun had gone down for the night. This is due to the fact that asphalt roofing shingles, like wood, tile, and concrete, absorb heat. Even after the heat has been removed, most conventional roofing materials continue to radiate stored heat for a long time. This heat radiates directly into your house, most notably into the attic area, putting a significant strain on your cooling system.

Metal roofs reflect light and heat and do not absorb it due to their low thermal mass. They cool down when the outside temperature drops. When combined with specialist reflective coatings that can re-emit heat, your attic will remain substantially cooler throughout summer, and your cooling system will notice the difference.

Efficient Ventilation

Remember how we said working with an expert metal roofing contractor? One of the primary reasons for this is that good ventilation of your metal roof will go a long way toward improving its cool, energy-efficient features. Proper ventilation will keep hot air moving out of the attic area by using a mix of soffit and ridge vents. This ventilation system is especially crucial during the winter months to assist vent attic moisture out of your house so that it does not gather in the attic area and cause mold and mildew problems.

If you reside in a very hot region of the nation, take the cooling process a step further by selecting metal roofing solutions that have inherent airspace between the back of the metal panel and the roof deck and underlayment. This additional gap prevents possible heat transmission from the metal to the underlying construction components.

Low-Maintenance Cool

Traditional roofing materials must often be fixed on a regular basis – especially after a very severe storm – and replaced every 15 to 20 years. This is an expensive cycle. When compared to metal roofing systems, which may last up to 50 years or more without having to be replaced, and many of them having guarantees of up to 40 years, this is a no-brainer. That is outstanding durability, and it means that the initial cost of a cool metal roof is much lower than the lifetime expenditures of most other more conventional solutions.

It is Cool to Be Green

Finally, metal roofing systems are a popular option among architects and designers who are creating environmentally-friendly structures. The majority of aluminum roofing systems are composed of 98 percent recycled components. They are pre-engineered and prefabricated, which reduces manufacturing and shipping expenses. As previously stated, the long life cycle of a metal roof boosts its appeal for sustainable structures. Finally, if the roofing system has to be disassembled and rebuilt, the whole structure may be recycled.
