Understanding the Role and Benefits of Roofing Underlayment

Roofing underlayment is a crucial component in any roofing system, providing an additional layer of protection between the roof deck and shingles. At Fasto Roofing, we emphasize the importance of using high-quality underlayment to enhance the durability and longevity of your roof.

What Is Roofing Underlayment?

Roof underlayment, also known as roofing felt or tar paper, acts as a barrier against water infiltration. It is installed beneath the roofing shingles and serves as a secondary layer of defense, ensuring that your roof remains watertight even under harsh weather conditions.

Types of Roof Underlayment

1. Asphalt-Saturated Felt

• Composition: Made from cellulose fibers and asphalt.

• Advantages: Provides good waterproofing capabilities and is relatively inexpensive.

• Application: Applied in overlapping layers onto the roof deck.

• Lifespan: Limited lifespan compared to synthetic underlayments.

2. Synthetic Underlayment

• Composition: Made from materials such as polypropylene or fiberglass.

• Advantages: Superior durability, tear resistance, and UV protection.

• Application: Lightweight and easy to install, offering better traction for roofers.

• Lifespan: Longer lifespan than asphalt-saturated felt, resistant to rot and decay.

3. Rubberized Asphalt Membrane

• Composition: Made from asphalt and rubber polymers.

• Advantages: Exceptional water resistance and durability, ideal for high humidity or extreme weather conditions.

• Application: Provides superior protection against water infiltration.

Importance of Roof Underlayment

Prevents Water Damage

• Function: Channels rainwater or snowmelt away from vulnerable areas.

• Benefits: Protects structural components of the roof from rot, mold, and water damage.

Reduces Risk of Roof Leaks

• Function: Acts as a barrier to prevent water from seeping under shingles.

• Benefits: Prevents leaks that can cause extensive damage to the interior of the home.

Extends Lifespan of Roofing Materials

• Function: Protects shingles from moisture, temperature fluctuations, and UV exposure.

• Benefits: Reduces the frequency of roof replacements or repairs.

Dangers of Not Using Roof Underlayment

Increased Water Damage

• Risks: Water can penetrate the roof deck, compromising the structural integrity of the home.

• Consequences: Leads to costly repairs, mold growth, and compromised indoor air quality.

Higher Risk of Roof Leaks

• Risks: Absence or improper installation of underlayment increases the likelihood of leaks.

• Consequences: Causes damage to ceilings, walls, and electrical systems, and weakens the roof structure.

Shortened Lifespan of Roofing Materials

• Risks: Exposure to extreme weather conditions without underlayment protection.

• Consequences: Accelerates aging and deterioration of shingles, leading to more frequent replacements.

Finding a Qualified Roofing Contractor

Research and Compare

• Steps: Look for contractors with positive reviews, experience, and proper licensing and insurance.

• Resources: Check online reviews and testimonials.

Ask for References

• Steps: Request references from previous customers to verify quality of work and proper underlayment installation.

• Resources: Contact references for feedback on their experience.
