FAQ — Roofing Calculator

Roofing Calculator kitna accurate hai?

Yeh calculator planning-level estimate deta hai jo aapke diye gaye area, pitch, material aur waste factor par based hota hai. Actual cost location, contractor aur market conditions ke hisaab se alag ho sakti hai, isliye final quote ke liye licensed roofing contractor se contact karein.

Roof pitch kya hota hai aur yeh calculation ko kaise affect karta hai?

Roof pitch roof ke slope (rise/run) ko batata hai, jaise 8/12 matlab har 12 inch horizontal run par 8 inch rise. Jyada pitch (steep roof) ka matlab hai jyada sloped surface area, isliye zyada material aur cost lagegi — calculator automatically iske hisaab se multiplier apply karta hai.

Waste factor kitna rakhna chahiye?

Simple gable roof ke liye 10% waste factor kaafi hota hai, lekin complex roofs (hips, valleys, dormers) ke liye 20-30% tak rakhna better hota hai taaki cutting aur fitting ke waste ko cover kiya ja sake.
