FAQs & Answers
- What is the difference between live load and dead load? Dead loads are static, permanent weights like the building itself, while live loads include variable factors like snow or occupancy.
- How do you calculate snow load for a roof? To calculate snow load, consider factors like roof slope, thermal properties, and geographic snow load standards.
- What happens if a roof can't support the snow load? If a roof is overloaded by snow, it risks structural damage or collapse, hence regular snow removal is essential.
- Are there building codes for snow load? Yes, building codes specify snow load requirements based on geographic location and roof design, ensuring safety and compliance.
