PVC Crown-Over or under HardiShingle
MVAgusta
| Posted in Construction Techniques on
Looking for advice on a gable end wall HardiShingle install. Like most old houses, this one has the crown nailed over the WRC shingles, resting between the roof sheathing and the face of the siding. Would it be best to do the same thing with the Azek-type crown that is being installed, or should I nail a frieze board up first, butt the shingles to that, then the crown over the frieze?
Going further, has anyone used the Restoration Millwork board with the j channel routed into it for a hardie install?

I wouldn't even consider not putting up some kind of frieze/rake board to begin with and then installing the crown and shingles to that. I've never even seen a detail like that before, not that that means anything - just doesn't make sense to me.
Otherwise, how would you handle the gaps that will result from the overlap of the shingles?
Can't comment on the trim stock itself, I've seen similar and liked the idea, but haven't used it.
Anyways, my $.02 for what it's worth...

The gaps and waves have always bothered me too, but that's the way they did it around here.
There is a lot of that here. The wall cedars were done first and probably extend 2" up in behind that crown all the way to the roof ssheathing. I have replaced same by using a sawsall to cut the nails in the crown to wall joint and working new shingles in.
But it is far easier to replace it.
However I wopuld definitely NOT just but the shingles to the frieze! That is a detail that gives me a lot of repairs for water penetration caused by those who do that. Besides, you make your work harder by needing to make an exact fit with the shingles.
Do this instead -
Let's say the frieze will be a 1x8.
First apply the tarpaper, then a 2x6 or rough cut 1x6.
Now, when you apply the 1x8 frieze, it covers over and down atop the cedars which you cut to appraoch the 2x6 in ahidden pocket.
Apply the new crown over that.
This detail will punch things out further, so if you are not replacing the roof above, you need a smaller crown.
ATW patterns would be mabe the 3042, 3043 or a bedmold 3075. Not sure what brnd you are using

Ok, I'll give that a try. I'm not using WRC for this though, the house is surrounded by tall oaks, full of squirrels that love to chew through cedar. Hopefully Hardie is a nasty to eat as the dust is to breathe in. Kinda feel bad about getting away from the original look, but I am going to shorten the exposure to 5" to at least get a little closer to "stock".
