The Roof Sentry System
Active moisture management designed to stabilize and restore commercial roof systems
Not a patch. Not a replacement.
A system built to solve trapped moisture at its source.
What Actually Causes Roof Failure
Moisture inside a roof system doesn’t just sit there.
As temperatures rise, it turns into vapor.
​
That vapor creates pressure inside the assembly-
putting stress on seams, adhesives, and insulation.
Most failures aren’t just water problems.
They’re pressure problems.
Why Traditional Approaches Fall Short
Coatings seal the surface.
Repairs fix visible damage.
Tear-offs remove everything.
​
But none of these directly address
trapped vapor pressure inside the system.
That’s the missing piece.
The Roof Sentry Approach
Roof Sentry is designed to:
-
Relieve internal pressure
-
Promote controlled moisture movement
-
Support gradual dry-down of the system
It works by creating a pressure differential
that allows trapped moisture to escape over time.
How It Works
1. Heat Activates the System
Solar loading increases internal vapor pressure
2. Pressure Is Relieved
The system creates a low-pressure pathway
3. Moisture Escapes
Trapped vapor is gradually removed from the assembly
The result is a controlled reduction in internal pressure and progressive dry-down of the roof system.
What Roof Sentry Makes Possible
-
Stabilization of moisture-affected systems
-
Increased viability of restoration
-
Reduced internal stress on the assembly
-
Extended service life
It works by creating a pressure differential
that allows trapped moisture to escape over time.
