Accurate Material Takeoffs & Ordering Rules

Ordering roofing materials without translating square footage into commercial packaging units leads to costly project delays or expensive surplus returns.

In standard roofing math: 100 square feet equals 1 roofing square, and 1 square of standard architectural shingles requires exactly 3 bundles. Calculating waste factors and rounding up to whole bundle increments ensures your installation goes uninterrupted.

Explore our detailed calculation walkthroughs, bundle conversion tables, and DIY takeoff guides below.
