Roof Area FAQ
What is a roofing square?
A roofing square equals 100 square feet (approximately 9.29 m²). It's the standard unit used by roofing contractors to measure and price projects.
Why include a waste factor?
Roofing materials must be cut to fit around valleys, hips, and edges. The waste factor accounts for these offcuts. 15% is recommended for most standard Malaysian homes.
