In North Texas, most homes have pitched roofs, which means the actual roof surface area is larger than the home’s interior square footage. Insurance companies, roofing contractors, and inspectors all calculate risk and replacement cost based on roof surface area — not living space.

For the majority of single‑family homes in North Texas:

· Typical roof surface area ranges from 2,000 to 3,000 square feet

· This equals approximately 20 to 30 roofing squares (1 square = 100 square feet)

· Larger or more complex homes may exceed 3,000 square feet of roof surface

Pitched roofs increase total roof surface area compared to a home’s footprint. Even a moderate pitch can increase roof size by 20–30% or more. Multiple gables, hips, valleys, and dormers further increase surface area and replacement cost.

· Insurance replacement cost is calculated using total roof surface area

· Larger roofs mean higher material and labor costs during replacement

· Higher roof values can increase premiums and deductibles

· Undocumented roof condition increases risk of claim denial or non‑renewal

Knowing your roof’s true size and condition helps homeowners protect their investment and avoid unexpected insurance surprises.
