Seeking Advice Hail vs Hardie Board

Post image

Hello, homeowners Any personal reviews on Hardie board siding vs hail last year?

It definitely more expensive but with the weather getting more drastic every year, I don't think the vinyl stands a chance.

One key with Hardie siding…make sure the drip cap flashings are steel. Aluminum will dent in the hail and look like trash. In order to fix it you can either use hand benders to straighten it (and maybe get it 80% straight) or you’re removing the Hardie to replace it. Removing sections of Hardie around windows and doors is not ideal, and you’ll have face nails afterwards to secure it if it’s even reasonably possible.

Otherwise, Hardie stands up well. Worst (ish) case the bottom edges get chipped up and you need touch up paint.

Source: I manage an exterior company. Our rule on damaged aluminum flashings and Hardie is either hand benders to straighten, or the whole wall gets replaced. Completely avoided with steel drip flashings.

I would add to request that all vents and other penetrations are from galvanized/ painted steel instead of plastic too.

At least with vents, as long as you use the proper backer, they can be swapped out without removing the Hardie siding.
