Question hardie board over masonite?

I have a house that is masonite sided (built in 1985), and would like to know if it is ok to hardie board side over the masonite? The masonite is beginning to warp and get buckled. Thanks.

The manufacturer recommends removing the existing siding.

Thanks Chris. Are there any downsides to leaving the masonite up? I'm sure the manufacturer has reasons.... any idea why?

If the Masonite is wavy and buckled, that alone is a reason to take it down. Number 1 being that you might have have water leaking behind the wall causing damage. (I've got pics I could send you. not good ). Number 2 reason is that if your wall is wavy, the new siding that you put up will just show it still. And lastly because of the pattern that the Masonite has, it won't let you continually get the same angle on your new lap siding beacause some of the boards will "fall" into the groove.

Not to mention, Masonite has claims going against them and you may be eligible for replacement of some sort. Here's the address.


Hope this has been helpful.

do you live in a home owner association that you can only have the same outside finish?
if not why hardie board.
If you like to paint about once every 2 years thats fine.
But why not vinyl siding.
it's low maintenance just water it with hose to clean it.
Now days people are looking for low maintnance home.
If you ever think of selling this might be a good selling point
