May not be compatible with all types of roofing materials
Some older synthetic products may not be as breathable as felt, potentially trapping moisture

Rubberized Asphalt: Enhanced Water Protection

Rubberized asphalt underlayments provide excellent water protection, making them ideal for areas prone to ice dams or heavy rainfall. These materials are self-adhering, creating a watertight seal around nails and other roof penetrations.

When to Choose Rubberized Asphalt

Rubberized asphalt is particularly useful in the following situations:

In valleys and around chimneys where water tends to collect
Along eaves to prevent ice dam damage
In areas with high wind-driven rain
On low-slope roof sections

Installation Considerations for Rubberized Asphalt

While rubberized asphalt offers superior water protection, it requires careful installation:

The roof deck must be clean and dry before application
Proper ventilation is crucial to prevent moisture buildup
Some products may not be suitable for use with certain types of roofing materials

Felt Paper: The Traditional Option

Felt paper, also known as tar paper, has been used as a roof shield material for decades. While it’s less common in new construction, it remains a viable option for some roofing projects.

Pros and Cons of Felt Paper

Felt paper has some advantages:

Lower cost compared to synthetic options
Familiar to most roofing contractors
Good water resistance when properly installed

However, it also has some drawbacks:

Can tear easily during installation
May wrinkle or buckle if exposed to moisture
Heavier than synthetic options, making installation more labor-intensive

Climate Considerations in Roof Shield Selection

Your local climate plays a significant role in determining the best roof shield material for your home. Different regions face unique challenges that can impact the performance of roofing materials.
