How do I estimate my wall area?

Multiply the perimeter of the house by the wall height, add the triangular gable ends, then subtract large openings like garage doors. Most contractors measure this for free.

Is fiber cement siding worth the extra cost?

Fiber cement costs more than vinyl but resists fire, rot, and impact, and holds paint for 10–15 years. It is a common upgrade in hail and wildfire regions.
