3 layers of Cedar Shakes and one layer of built up to tear off.
We installed 1/4" primed Dens Deck under the brown section of IB. The IB Deckshield was installed over 1/4" sanded plywood with floated seams. Both the 50mil IB PVC and the IB Deck Shield were fully adhered and of course, heat welded.
On the main roof we installed a Dark Brown 16" SL Panel manufactured by Bridger Steel out of Billings, MT.
I wish the pictures would have turned out a little better.
This is a really good example of the IB Deck Shield. As always, the IB Roof installed without issue. IB Roof really is an impressive system!
