🚫 7 Problems With Synthetic Roof Underlayment

While synthetic roof underlayment offers numerous advantages, it is not without its challenges. In this section, we will explore seven common problems associated with synthetic roof underlayment that homeowners and contractors should be aware of before making a decision.

1. Cost Concerns

One of the primary issues with synthetic roof underlayment is its cost. While it offers superior performance in many areas, it comes at a higher price point compared to traditional asphalt felt. The initial cost can be a significant factor for homeowners working within a tight budget.

Why It Matters:

• Budget Impact: The higher cost of synthetic underlayment can significantly affect the overall budget of a roofing project.
• Return on Investment: Homeowners need to weigh the upfront costs against the long-term benefits, which may not always be straightforward.

Mitigation:

• Shop Around: Prices can vary between suppliers, so it pays to compare different options.
• Consider Long-Term Savings: Evaluate potential savings from reduced maintenance and longer lifespan.

2. Slipperiness

Synthetic underlayment is known for being more slippery than traditional felt, particularly when wet. This can pose safety hazards for roofing contractors during installation and maintenance.

Why It Matters:

• Safety Risks: Increased risk of falls and injuries can occur during installation or roof inspections.
• Insurance Implications: Potential for higher insurance costs or claims if accidents happen.

Mitigation:

• Use Traction Aids: Roofers can use shoes with better grip or additional traction aids designed for synthetic underlayment.
• Safety Protocols: Implementing stricter safety protocols and using fall protection can minimize risks.

3. Heat Retention

Synthetic underlayment materials can retain more heat than traditional felt, leading to higher temperatures in the attic space. This can impact the overall energy efficiency of your home.

Why It Matters:

• Increased Cooling Costs: Higher attic temperatures can translate to increased cooling costs during hot weather.
• Potential Roof Damage: Prolonged exposure to high temperatures can accelerate the aging process of roofing materials.

Mitigation:

• Proper Ventilation: Ensure that your attic is well-ventilated to help dissipate heat.
• Reflective Roofing Materials: Consider using reflective roofing materials to reduce heat absorption.

4. Limited Breathability

Synthetic underlayment is typically less breathable than felt, which can trap moisture beneath the roof covering. This can lead to mold growth and damage to the roof deck.

Why It Matters:

• Moisture Issues: Trapped moisture can cause wood rot, mold, and other structural issues.
• Indoor Air Quality: Mold growth can negatively impact indoor air quality and cause health problems.

Mitigation:

• Balanced Ventilation: Ensure your roofing system includes balanced ventilation to allow for proper air circulation.
• High-Quality Materials: Some synthetic underlayments are designed with enhanced breathability; choosing these can mitigate moisture issues.

5. Environmental Impact

While synthetic underlayment offers durability, it is often made from petroleum-based products, raising concerns about its environmental impact.

Why It Matters:

• Sustainability Concerns: Petroleum-based products are not renewable and have a larger carbon footprint.
• Disposal Issues: Synthetic materials are not biodegradable, contributing to landfill waste.

Mitigation:

• Recycling Programs: Some manufacturers offer recycling programs for synthetic underlayment.
• Eco-Friendly Alternatives: Consider underlayments made from more sustainable materials if available.

6. Compatibility Issues

Synthetic underlayment may not be compatible with all roofing materials. Some roofing manufacturers may void warranties if their products are used with certain types of synthetic underlayment.

Why It Matters:

• Warranty Concerns: Voided warranties can lead to significant out-of-pocket expenses if roofing problems arise.
• Material Compatibility: Ensuring compatibility between underlayment and roofing materials is crucial for optimal performance.

Mitigation:

• Check Manufacturer Guidelines: Always check the roofing manufacturer’s guidelines for approved underlayment materials.
• Consult with Professionals: Working with knowledgeable roofing professionals can help ensure compatibility and adherence to warranty requirements.

7. Installation Challenges

While synthetic underlayment is generally easier to install than traditional felt, it still presents certain challenges. Issues such as improper fastening, wrinkles, or tears can compromise its effectiveness.

Why It Matters:

• Performance Issues: Improper installation can lead to leaks, reduced effectiveness, and potential roof damage.
• Longevity: Ensuring correct installation is vital for the longevity of the underlayment and the overall roof system.

Mitigation:

• Professional Installation: Hiring experienced roofing contractors can ensure proper installation and reduce the risk of issues.
• Follow Best Practices: Ensure that the underlayment is installed according to manufacturer recommendations and industry best practices.
