Metal Roof Over Sips

For the metal roofing it s a not brainer.

Metal roof over sips.

Specifying a cold roof or simply over sheathing the roof with an additional layer of osb staggered over the panel joints will eliminate the possibility of shingle ridging. I would suggest allowing this to vent in some way the metal directly over the sips roof even with ice and water will get extremely hot. The pitch of the roof is very low only 1 2 inch in 12 and the metal roofing has been applied directly over the sips with no air channel beneath the roofing for ventilation. The ridges caused by the expansion of sip roof panels may be an aesthetic blemish but it does not affect the performance of the roofing or the sip roof panels.

The roof structure is 10 25 sips on a 2 12 pitch and the developers are going with either metal roofing or a torch down system. Make certain to tape seal all panel joints. Sip panels must be air and watertight. Chris the metal roof went on top of the sips with triflex between.

We ll strap it and create an air space but we ve never done a torch down on sips. Here are some important considerations. Can i install a metal roof directly over top of the sips. Ensure that panel joints are level to one another as variations in panel height can cause deflection in the roofing material.

There is a guy in nh that places pex tubing in the space between the strapping and uses this for solar hot water collection.
