GAF Roofing
A roofing system is made up of multiple layers that work together to protect a home.
The underlayment is installed over the roof deck and beneath the exterior roofing material. It provides an additional layer of protection against moisture that may reach beneath shingles or other roof coverings.
Quality underlayment helps protect against:
Wind-driven rain
Water intrusion
Roof leaks
Moisture damage
Weather exposure
In Florida, where roofs experience heavy storms, humidity, and hurricane conditions, proper roof protection layers are extremely important.
GAF StormGuard® is a self-adhered leak barrier designed to provide enhanced waterproof protection in vulnerable roof areas.
It is commonly used in areas where water intrusion risks are higher, such as:
Valleys
Eaves
Rake edges
Around chimneys
Skylights
Roof penetrations
StormGuard is designed to create a waterproof barrier that helps protect areas most susceptible to leaks.
WeatherWatch® is another GAF leak barrier designed to provide protection against moisture intrusion.
It is commonly used in areas where additional protection is needed, including:
Valleys
Sidewalls
Dormers
Penetrations
These areas require extra attention because they experience increased exposure to water flow and weather conditions.
GAF offers several roof deck protection products designed to provide a secondary layer of defense beneath the roof covering.
These products help:
Protect the roof deck
Reduce moisture exposure
Improve the overall roofing system
Examples include:
Tiger Paw™ is a synthetic roof underlayment designed as an alternative to traditional felt paper.
Benefits include:
Lightweight design
Durable construction
Walkability during installation
Moisture protection
Deck-Armor™ is a premium synthetic roof deck protection product designed to help provide reliable coverage beneath shingles.
Features include:
Synthetic construction
Improved tear resistance
Moisture protection
Better durability compared to traditional felt underlayments
Metal roofing systems require specialized protection because metal panels expand and contract with temperature changes.
GAF manufactures underlayment solutions designed for certain metal roofing applications.
These products help provide:
Secondary moisture protection
Separation between roof deck and metal panels
Additional weather resistance
Proper underlayment selection is important for maximizing the performance of a metal roofing system.
Although ventilation is not an underlayment, it is an important part of the complete GAF roofing system.
GAF Cobra® ventilation products are designed to help improve attic airflow.
Proper ventilation can help:
Reduce excessive attic heat
Control moisture buildup
Improve attic performance
Support roof longevity
A balanced roofing system includes both moisture protection and proper ventilation.
GAF promotes a complete roofing system approach where all components are designed to work together.
A complete system may include:
Leak barriers
Roof deck protection
Starter shingles
Asphalt shingles
Ridge cap shingles
Ventilation products
Accessories
Each component contributes to the overall performance and reliability of the roof.
