Estimate roof replacement costs based on area and pitch
A new roof is a major investment. This calculator factors in pitch and waste.
Tear-off: Removing old shingles adds $1-2 per sq ft. Steep Pitch: Roofs steeper than 6:12 cost 20-50% more due to safety requirements.

A roofing square is an area of 100 square feet (10' x 10'). It's the standard unit of measurement for roofing materials.
Steeper roofs (higher pitch) increase costs because they require more safety equipment, more labor time, and slightly more material surface area.
While possible in some areas (reroofing), most professionals recommend a full 'tear-off' to inspect the underlying wood deck for rot or damage.
