Should ice and water material be used over the entire roof with SIP panels?

The answer may surprise most traditional stick builders.

The long-term performance and durability of Enercept SIP roof assemblies is dependent on the roof assembly’s ability to dry to the side to which it gets wet. SIPs have low permeability, which means that they cannot dry through the thickness of the SIP.

Enercept Structural Insulated Panels (SIPs) expert Jon Golz talks about Enercept SIP roof panels and the recommended course of action when sealing your SIP roof.

Enercept details of roof panel joints describe the use of sealant and SIP tape to mitigate air flow through the panel joints. The SIP tape is applied on the interior side of the panels in climate zones 5, 6, 7, 8. The use of SIP tape over the panel joints meets the building code requirements of a vapor retarder for the assembly.

Enercept highly recommends that designers and builders consider detailing the roof assembly in a way which allows drying of the OSB to the side on which the OSB became wet.
