No Sul do Brasil

Neve é rara mas geada pesada é comum na Serra Gaúcha e Catarinense. Gelo acumulado pesa significativamente. As estruturas de telhado no Sul são projetadas para cargas extras por causa do frio e vento. Se vive em região de neve/geada: verifique com engenheiro se a estrutura do telhado suporta acúmulo.

Referências

Neve fresca: 50-150 kg/m². Compactada: 200-400. Gelo: 900 kg/m³. Telhados padrão suportam 100-200 kg/m².

⚡ CalcWolf Insight

The most dangerous time for roof collapse is not during the snowstorm — it is 2-3 days after, when warm temperatures partially melt snow into dense, heavy slush. Snow that seemed manageable at 15 PSF can become 25+ PSF as it compacts and absorbs meltwater.
