Metal roofing materials are non-combustible and fire resistant. Sparks and embers will not light it. Keep in mind that part of the overall classification of a roof depends on the material below the surface, which can also catch fire in high heat. For metal roofing service, you can contact us now.
Most metal roofs are on combustible materials such as Wood brick, for example, has a lower C class for this reason (For problems in the event of a fire in the home, see the note under "Defects in metal roofing".)

The metal surface reflects heat: Metal reflects the radiant heat of the sun and thus minimizes midday heat. You can save the energy needed for air conditioning during the day.
Regarding the heat and cold insulation values of metal roofing: Although the material itself has a low R-value of insulation, metal roofing can be placed on top of foam insulation, which has a very high R-value.
Most metal roofing materials can be installed on a slightly sloped roof without leakage. The minimum roof pitch for metal roof tiles is usually 3 in 12 – this means the roof rises 3 inches for every horizontal foot.
The dark color of the metal roof heats up quickly in the sun and causes snow to melt. Metal roofs are great for the snow side as they are fire-resistant, lightweight, and ideal for shedding snow. The panels are laid on solid foam insulation to maintain a high R-value.
Petroleum and fossil fuels are used in the production of asphalt. In addition, asphalt roofs need to be replaced every 15 to 20 years, leaving nearly 20 billion pounds of old asphalt tiles in landfills in the United States each year, according to the Environmental Protection Agency.
