Frequently Asked Questions About Roofing Materials

Which roofing material is the lightest?

Of the 10 materials above, polycarbonate plastic sheets and artificial leaves and paintings are the two lightest, with weights ranging from 1 – 4 kg/m². However, artificial leaves and paintings often have lower weights (about 1 – 3 kg/m²) due to their thin structure and ultra-light plastic/synthetic fiber materials.

Which roofing material is the most durable?

Slate is the most durable roofing material on the list, thanks to its exceptional lifespan of up to 100 years, excellent weather resistance and low maintenance requirements. If you prioritize maximum durability and are willing to invest, slate is definitely the ideal choice.

Which roofing material is the best for heat and sound insulation?

Foamed steel panels are the best insulation and soundproofing material on the list thanks to the foam core (PU or EPS) that effectively reduces heat and sound transmission. The superior performance of this material is especially suitable for projects that require a cool and quiet environment, such as factories, cold storage, or urban housing.

What factors affect roof life?

According to Kosmos' experience, there are 5 main factors that affect the life of a roof including:

1. Quality of roofing materials: The more durable and suitable the material is for the environment in which it is used, the longer the life of the roof. For example, natural slate can last up to 100 years, while metal roofing has an average life span of about 20 to 50 years depending on the type.
2. Construction skills: If the construction process is not done properly, even with good materials, the roof can still leak and be damaged early. Correct installation and effective waterproofing are key factors.
3. Climate and environmental conditions: Environments with lots of heat, storms, strong winds or high humidity will cause the roof to deteriorate faster. For example, coastal areas with salty air will easily corrode metal roofs.
4. Roof design and slope: A roof with a suitable slope helps drain water quickly, avoid stagnation, and reduce the risk of leaks and mold. Flat or less steep roofs require better waterproofing solutions.
5. Regular maintenance and cleaning: If the roof is inspected and maintained regularly (such as cleaning gutters, promptly handling cracks, replacing damaged roofing), its lifespan will be significantly extended.
