Reducing the heat of metal roofs with metal roof coating requires specific application techniques. Metal roofing is commonly employed in industrial buildings like warehouses and factories, as well as in residential settings.
Although it is quite often used and quite popular among people, it’s just that. Unfortunately, it can make the room feel hot when used in buildings.
Because of the heat factor, the metal roof is less comfortable when applied to a house roof. If you decide to continue to be an option for use in your residence, you should add a heat sink as an insulator in its application. This insulator will provide an effect that can make a metal roof relatively comfortable to use on a residential roof.
During the day, the heat temperature that occurs in the room is caused by the radiation heat transfer from the heat of the roof to the ceiling of the house. Daytime temperatures caused by heat rays can reach around 70ºC. The displacement resulting from heat radiation is a unique phenomenon or thing to be observed.
In these circumstances, the process of rising temperatures will go hand in hand with an increase in heat radiation. For example, a roof at 70ºC can emit more than 10 times the heat radiation to the ceiling below. A roof coating that reduces heat radiation is a solution for handling rising room temperatures.
Spray-On Roof Coating by Using Polyurethane Foam
Polyurethane foam is a silencer and heat barrier with a form of solid foam that functions primarily as a Coating metal roof. In use is done by spraying foam on the field to be protected. The material’s nature is very light and can function as insulation in materials such as metal, concrete, wood, or zinc.
Using Polyurethane Foam as metal roof insulation can regulate indoor temperatures—making it cooler in summer and warmer in winter, thus minimizing the use of heating and cooling systems. This coating system can serve as an effective solution to reduce the heat from a zinc roof surface.
Roof Coating To Stop Leaks
One of the causes of leakage is a crack in the roof or cover of the building—cracked walls, allowing water to seep into the room. Other spatial elements, such as walls and floors, will be damaged if left unchecked.
To handle leaks effectively, you should use a metal roof coating embedded with a leak-proof and silicone coating, which also serves as a rust inhibitor. This coating system shields the house from seepage, ensuring long-term durability and protection against ponding watering.
1. Water Based
This leak coating material is made from basic ingredients, such as water. Suitable for coating surfaces, tiles, zinc, metal, and concrete gutters. The coating agent reliably covers high-absorbency materials such as plastering, non-concrete, brick, sandstone, and Kalimantan stone. You can use brushes, rollers, and spray tools to apply it.
2. Torching membrane
This leakproof coating material uses a combustion system with a mixture of bituminous layers. This material has high elasticity. Suitable for dak, basement, groundwater tanks, and reservoirs. This coating material is resistant to UV and IR rays from the sun. You must burn the material on the area to be coated before applying it.
Roof Coating Colors with Aluminum Foil
Aluminum foil is an ideal coating for mitigating solar radiation, capable of reflecting up to 97% of the heat that strikes the roof surface. Its heat-reflective properties make it a popular choice for reducing heat under metal roofs, offering various advantages including multiple color options.

The intended advantages include aluminum foil material, which is strong, elastic, and resistant to water and freon. Other advantages are the relatively safe nature of the material as an environmentally friendly metal roof coating, protecting the building from leaks due to rain, and protecting the ceiling from damage due to sagging, which heat can cause from the sun.
Rusty Metal Roof Coating
Corrosion is a major problem that attacks metal materials, including mild steel. Although some manufacturers label their products rust-proof, they are not entirely the case.
They only coat it with anti-rust substances. If the coating is disturbed, rust will certainly appear and spread throughout the surface of mild steel. In fact, the use of mild steel began to rise.
It is essential to use roof coatings, starting from wood replacement materials for roof trusses to construct building frames instead of concrete. Regarding its strength, mild steel cannot be underestimated.
If the wood is easily weathered, easily eaten by termites, also flammable by fire, mild steel does not. Besides, mild steel is also strong and withstands pressures up to 240 – 370 MPa, while concrete can only withstand pressures up to 100 MPa.
