Improper Roof Ventilation Causes Warping Roof Decking in Hardin Valley TN

This is an image from a roof pitch gauge showing that this roof is either 12:12or a little steeper.

This is in addition to the existing Home.  The shingles are Certainteed landmark driftwood, which will propose to Roof in the rest of the home.

The ventilation for this roofing system will be provided by Styrofoam that’s to keep the insulation between the vaulted ceiling and roof rafters channelized. This ventilation system will allow air to move through the vaulted ceiling where there is insulation.

On the rear portion of the roof, the deck boards will need to be removed and replaced to add back the insulation channels. These deck boards at the west-facing slope of the roof are warping as a result of bad Ventilation.

There’s no ventilation possible because if you look closely you will see that there are blocks preventing air from moving into the vaulted ceiling and to the ridge.
