Improper Roof Ventilation Causes Warping Roof Decking in Hardin Valley TN

Knoxville,  TN

Improper Roof Ventilation Causes Warping Roof Decking in Hardin Valley, TN. Litespeed Construction is a Knoxville Roofing Company, and we determined that ventilation issues with this roof are causing the roof boards to leak. One of the most important things for a roofing company to inspect is how the roof breathes and ventilates.

 

This home has a vaulted ceiling and no ventilation for this roof from the soffit to the ridge. The west-facing portion of this home has warping roof deck boards that, at first glance, might appear to be rotten decking. The real culprit for this issue is improper roof ventilation!

 

This property is located in the Hardin Valley area, a suburb of Knoxville TN.
