RE: [hreg] SIP roofs
We engineer SIP structures and work with SIP builders. We have done Three Galveston SIP homes plus the Seabrook Sailing Club (see photos).
The SSC is all SIP construction (floor, walls, and roof). We use 8" and 10" SIPs for new roof structures, But for reroofing a 4" or 6" is plenty.
There is a type of single skinned SIP that is intended to go over the decking of a house roof. Just scewed on then normal roofing I nailed on top.
The single skin saves a little money, but not much. If you leave both skins and leave it as a standard SIP it is much much stronger.
Since there is no appreciable cost difference between 4" and 6" roof SIP This allows opportunitities to extended the overhangs up to as much as 4' which is a nice feature.

Since there has been a lot of talk about roofs lately....
Has anyone added SIPs to a standard stick built home?
I saw a show last year on one of the misc cable channels where ply and shingles were removed. Then SIP panels were installed. They also added solar panels, but I was more interested in feedback about the roofing.
I assume that there would have to be some additional structure to support additional weight and it would change the look of the home a little too.
Has anyone done this to a local home? Are there roofing companies that offer this as an option?
The show I saw modified a home in California.
Any feedback would be appreciated.
