Reducing the heat of metal roofs with metal roof coating requires its own technique in its application. Metal roofing types are usually used as roofing in buildings such as warehouses or factories, but there is also a house.
Although it is quite often used and quite popular among the people, it’s just that, unfortunately, it has an effect that can make the room feel hot in its application in buildings.
Because of the heat factor, the metal roof is less comfortable being 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, 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 phenomenon or thing that is unique 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 solution for handling rising room temperatures is a metal roof coating by reducing heat radiation.

Spray-On Metal 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 a metal roof insulation can make the temperature in the room cooler in the summer and hotter in the winter so that the use of cooling or heating can be minimized. This material can be used as a solution to reduce the heat of a zinc roof.
Metal 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. If left unchecked, other spatial elements, such as walls and floors, will be damaged. To deal with leaks, you need to use a metal roof coating with a leak-proof coating. The goal is to protect parts of the house from water seepage. To be precise, you should choose according to your needs.
1. Water Based
This leak coating material is made from basic ingredients that are 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 palimanan stone. To apply it, you can use brushes, rollers, and spray tools.
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. To apply it, you need to burn the material on the area to be coated.
Metal Roof Coating Colors with Aluminum Foil
Aluminum foil is a coating that is quite ideal for retaining solar radiation with the ability to up to 97% of the total radiation entering the roof because it does not absorb heat but reflects heat. Aluminum foil is a popular choice to anticipate the heat of metal roofs with various advantages and color choices.
The intended advantages include aluminum foil material, which is strong, elastic, and resistant to water and freon. Besides, 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 the 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 to be rust-proof, they are not entirely the case.
They only coat it with anti-rust substances. If the coating is disturbed, then certainly rust will appear and spread throughout the surface of mild steel. In fact, the use of mild steel began to rise.
Starting from wood replacement materials for roof trusses to construct building frames instead of concrete, it is essential to use metal roof coatings. 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, withstood pressures up to 240 – 370 MPa, while concrete can only withstand pressures up to 100 MPa.
