One of the greatest benefits is its slow cure time.
Although it sounds like a disadvantage it really is one of the key benefits and here is why.
What is the cure time for liquid roof.
At first glance this may seem like a disadvantage until you realize that even when wet the material provides a waterproof barrier.
The higher the temperature the quicker.
How long will it take for the liquid roof liquid rubber to cure.
Undersize rafters and sheathing.
Heavier films may take longer.
Another unique advantage is the slow cure time or the time it takes for the liquid material to fully adhere and harden on the roof deck.

The lowest temperature at which any cure takes place is 55 degrees.
However as the liquid roof begins its cure process and solvent slowly evaporates the sheet will shrink and return to its original shape.
If rafters are too skimpy the roof will sag especially along the ridge.
Generally 24 hours until it develops a skin and approx 72 hours until you can walk on it.
If the sheathing is too thin the roof will sag between rafters and look wavy.
Other coatings dry quickly leaving air trapped between the substrate and the coating this provides for an unstable roof coating and eventually leads to cracking and separation.
Whatever the cause if the remedy is stripping back extensive sections of roofing to replace faulty flashing reroofing may be the most cost effective cure.
Cure time is controlled by temperature.
