Roofing systems must meet very strict fire-resistance requirements. There is no such thing as a 100% fire-proof roof – some roofing systems are more resistant to the exposure to flames, others catch fire more easily, but no material resists fire endlessly –, but every roofing material needs to comply with fire resistance regulations pertaining to resistance to fire from above the roofing as well as to exposure to fire coming from inside the building. While Denver roofer compliance means that all available roofing materials provide a certain amount of protection against fire, roof systems rated as Class A are usually made from non-combustible materials, while Class B roofing systems use combustible materials that have been treated to improve their fire-retardant qualities. Here are the Denver roofer fire resistant materials that come with the highest fire-resistance rating:
- Metal – rated as Class A systems, metal roofs use alloys that do not ignite, therefore they are suitable for very dry and fire-prone areas such as Nevada;
- Slate – this natural material also comes with outstanding fire-resistant features, but it is also very heavy and therefore not suitable for lightweight construction;
- Clay and concrete – two very durable roofing solutions that offer excellent protection against fire;
- Asphalt roofs – these systems are preferred not only for the variety they offer in terms of design, for easy installation and low cost, but also for the enhanced protection they offer against fire.
