James Hardie fiber-cement siding resists rotting or cracking and it resists damage from rain and hail. I conducted my own water testing on this siding before I ordered an entire pallet of this awesome stuff. Click here to see the "Siding" pages here at Circle Oaks. This siding is also available pre-finished with a 15-year paint warranty. Best of all, James Hardie siding is non-combustible (cement doesn't burn!), with a limited, transferable warranty for up to 50 years. No wonder it's protecting over 3.5 million homes in North America alone.
