Roof Shinglesని ఎలా లెక్కించాలి

Roof Shingles అంటే ఏమిటి?

A roof shingles calculator estimates the number of shingles or tiles, and the number of "squares" (100 sq ft / 9.29 m²), needed to cover a roof. It accounts for pitch, waste, and overlap.

1. 1Measure the footprint area of the roof from below (length × width of house)
2. 2Apply pitch multiplier: 4/12 pitch = ×1.054, 6/12 = ×1.118, 8/12 = ×1.202
3. 3Add 10–15% waste allowance for valleys, hips, and ridges
4. 41 square = 100 sq ft; most shingle bundles cover 33 sq ft → 3 bundles per square
