The low slope roof system components are roof deck, vapor control layer and roofing membrane. These components work together to form a robust and weather tight roofing assembly.

Choosing the right combination of these components based on the building’s requirements and conditions will prevent water damage and extend the roof’s life.

Roof Deck

The roof deck is the base of any roofing system, provides structural support to the entire assembly.

In commercial buildings steel is the most common material used for roof decks because of its strength and durability.

But an insufficient slope can cause water ponding which is one of the common causes of low slope roof failures.

Getting the roof deck right will prevent these issues. Adequate slope and good materials will mitigate the risks of water ponding.

This foundation layer will set the stage for the other components to work. Roofing contractors can help ensure that the roof deck is properly sloped and constructed with the best materials.

Vapor Control Layer

The vapor control layer prevents moisture from entering the building materials, prevents damage over time.

This layer stops water vapor from reaching critical areas and protects the roof’s structural integrity. Roofing contractors play a crucial role in ensuring the vapor control layer is installed correctly to prevent moisture damage.

Installation is key to the overall performance of the roofing system.

Roofing Membrane

The roofing membrane is the waterproofing component of a low slope roof system, protects against water intrusion and UV rays.

Hot asphalt is often used as an adhesive in built-up roofing and modified bitumen installations, providing a strong bond and durability.

Reflective coatings can extend the life of these membranes by shielding them from UV degradation. Choosing the right roofing membrane will extend the life of the roof.
