A James Hardie project is more than choosing a color
James Hardie offers multiple exterior siding formats, including lap siding, panel siding, shake and shingle siding, architectural panels, trim and soffit. The right combination depends on the architecture of the home, the look you want and the details required around windows, doors, corners and roof transitions.
Before installation begins, the existing exterior must be evaluated so the project scope accounts for removal, substrate conditions, flashing details and any repairs that become visible during tear-off.
Professional installation matters
James Hardie publishes product-specific installation instructions and states that a full Hardie siding project is best undertaken by siding experts familiar with fiber cement. Requirements can include approved fastening methods, spacing, clearances, flashing and product-specific details. Those details are one reason a siding project should be planned around the actual home rather than a generic checklist.

- Review the existing exterior and likely replacement scope.
