Roofing projects rely on a dependable underlayment stage, and Lowe’s roofing felt paper remains a common choice for many American homes. This article provides an in-depth Nearn expert overview of roofing felt, its role in roof assemblies, available Lowe’s options, installation basics, and practical tips to optimize performance and durability. Whether replacing old tar paper or selecting a new underlayment for a shingle or metal roof, understanding Lowe’s offerings helps ensure a secure, weather-tight roof.
What Is Roofing Felt Paper
Roofing felt paper, often called tar paper or asphalt felt, is a protective underlayment installed between the roof deck and the final roofing material. It guards against moisture intrusion, provides a temporary barrier during installation, and helps safeguard against wind-driven leaks. Lowe’s typically stocks several types of roofing felt that align with common US roofing practices, including 15-pound and 30-pound felt, as well as newer synthetic underlayments. The felt’s weight and material influence tear resistance, water resistance, and overall durability.
Key Lowe’s Roofing Felt Options
Choosing the right underlayment at Lowe’s involves understanding material composition, weight, and climate considerations. The main options include:
- Aphalt-Saturated Felt (15# and 30#): Traditional tar-based felt offering moisture protection and a reliable nailing surface. Common for asphalt shingle roofs, with 15-pound felt suitable for moderate climates and 30-pound felt providing enhanced durability in more demanding conditions.
- Synthetic Roofing Underlayment: Lightweight, tear-resistant, and often more weatherproof than traditional felt. Suitable for various roof types and often used under metal or high-end shingle systems.
- Combination Underlayments: Some Lowe’s products blend felt with polymer components for improved water shedding and durability in wet climates.
When selecting, homeowners should reference local building codes and contractor recommendations. In high-wind or heavy-rain regions, more robust underlayments can improve performance and longevity.
Installation Guidelines For Roofing Felt Paper
Proper installation is essential for maximizing the underlayment’s protective benefits. The following guidelines reflect common industry practices and Lowe’s product supports:
- Aim for a clean deck: Ensure the roof deck is dry, smooth, and free of protruding nails or debris.
- Overlap and alignment: Standard overlap is typically 19 inches for felt paper. The exact overlap may vary by product; follow manufacturer instructions printed on the packaging.
- Securing: Fasten felt with roofing nails or staples as specified by the product. Begin at the eaves and work upward, maintaining consistent tension to avoid wrinkles.
- Seaming and orientation: Roll out the felt with the smooth side facing up for better barrier performance. Stagger seams in adjacent rows to reduce potential leak paths.
- Overhang and trim: Extend the felt a few inches beyond the eaves and rake edges to prevent wind uplift. Trim carefully to fit roof contours.
- Weather considerations: Do not install underlayment in rain or when the deck is wet. Allow a dry window for effective bonding and sealing with the final roofing material.
For optimal results, consult the specific Lowe’s product data sheet and any local building codes. If a professional is handling installation, provide clear instructions and ensure compliance with warranty requirements.

Compatibility With Roofing Materials
Underlayment compatibility is a critical factor for a long-lasting roof. Roofing felt works well under asphalt shingles and many metal roofing systems, but synthetic underlayments can offer superior performance in some cases. Lowe’s often provides guidance on which underlayment types pair best with different roofing materials. The right choice takes into account climate, roof pitch, attic ventilation, and the anticipated moisture load.
Durability, Weather Resistance, And Codes
Durability depends on material composition, climate exposure, and installation quality. Traditional asphalt felt has good water resistance but can degrade over time under prolonged UV exposure if not protected by the final roof covering. Synthetic or reinforced underlayments tend to offer improved tear resistance and longer service life in extreme weather zones. Local building codes may require or recommend a specific underlayment type, particularly for low-slope roofs or areas prone to heavy rainfall.
Key considerations:
- Rain and UV exposure tolerance varies by product; synthetic options often perform better in sun-drenched regions.
- Proper ventilation and insulation within the attic influence moisture buildup behind the underlayment.
- Warranty terms from Lowe’s or the underlayment manufacturer may require adherence to installation guidelines for coverage to apply.
Cost, Availability, And Shopping At Lowe’s
Pricing for roofing felt at Lowe’s depends on weight, material, and current promotions. Typically, 15# felt is the most economical option, while 30# felt and synthetic underlayments carry higher per-unit costs but offer greater durability. Availability varies by location and season. Lowe’s provides in-store pickup and online ordering with delivery options, plus customer support to help select the right product for a given project.
Helpful shopping tips:
- Compare product specifications like weight, tear resistance, and UV tolerance across options.
- Check local building codes to confirm required underlayment type for your project.
- Ask for moisture resistance ratings and warranty details when evaluating Lowe’s products.
Maintenance, Inspection, And Replacement
Underlayment typically requires little maintenance once the final roof is installed, but inspections after severe weather are advisable. Look for signs of moisture intrusion, curling, or lifted edges. If damage is detected, replace affected sections promptly to prevent leaks. When reroofing, Lowe’s products can be matched to the existing system to maintain continuity in performance and warranty continuity.
Safety And Handling
Handling roofing felt involves basic safety practices to avoid injuries and ensure material integrity. Wear gloves to protect hands from rough edges, and use proper lifting techniques for heavier felt rolls. Store rolls on a dry surface away from direct sunlight to prevent premature material aging. When cutting rolls, use a sharp utility knife and a straight edge to produce clean, accurate cuts.

Practical Comparison: Traditional Felt vs. Synthetic Underlayment
| Feature | Traditional Felt (15#/30#) | Synthetic Underlayment |
|---|---|---|
| Water Resistance | Good; adequate with proper installation | Excellent; superior moisture shedding |
| Durability | Moderate; prone to tearing when wet | High; tear-resistant even in cold |
| Weight | Heavier; easier to handle for long runs | Lightweight; easier to handle in many layouts |
| UV Tolerance | Limited; covered by final roof soon after install | |
| Cost | Lower upfront | Higher upfront |
Homeowners should weigh these factors based on climate, roof type, and budget. Lowe’s staff can help interpret product sheets and select the best underlayment for a specific project.
