Roofing underlay is a crucial component of any roofing system. It acts as a protective barrier, ensuring the longevity and durability of your roof. At Collins & Son Roofing, we believe in the importance of understanding every aspect of your roofing system. Here’s a deep dive into the world of roofing underlay.
What is Roofing Underlay?
Roofing underlay, sometimes referred to as “shingle underlay”, is a protective layer placed between the roof’s framing materials and the top layer of shingles. Its primary role is to safeguard against potential leaks, mold, and water damage. With advancements in technology, there are now various underlay options tailored to different weather conditions, ensuring optimal protection for your home.
The Three Main Types of Roofing Underlay
1. Asphalt-Saturated Felt Underlay
This traditional underlay, often called “felt paper” or “tar paper”, is made from a blend of asphalt, plant fibers, polyester, bitumen, and fiberglass. It’s water-resistant but not entirely waterproof, making it suitable for sloped roofs where water can easily drain.
Pros:
- Cost-effective
- Water-resistant
- Suitable for sloped roofs
Cons:
- Not entirely waterproof
- Not ideal for flat roofs
- Asphalt may degrade over time
2. Rubberized Asphalt Underlay
A more modern option, rubberized asphalt underlay is often made without actual asphalt. Instead, it combines recycled rubber, polyethylene, polyester, and fiberglass. This underlay is heat-fused to form a seamless membrane, ensuring an airtight seal.
Pros:
- Waterproof
- Adaptable to extreme temperatures
- Low maintenance
Cons:
- Pricier than other options
- Some types may not be fire-resistant
3. Non-Bitumen Synthetic Underlay
Constructed from thermoplastics like polyethylene or polypropylene, this underlay is known for its waterproofing, flexibility, and strength. It’s lightweight and resistant to both fungus and UV rays.
Pros:
- Highly waterproof
- Durable and lightweight
- UV and fungus resistant
Cons:
- More expensive due to manufacturing materials
Top Benefits of Roofing Underlay
1. Enhanced Curb Appeal
Roofing underlay provides a smooth, even surface for shingle installation, enhancing the overall look of your property.
2. Increased Fire Safety
Choosing the right underlay can help your shingles meet Class A fire requirements, ensuring safety for your home.
3. Superior Weather Protection
While shingles are the primary defense against external elements, the underlay acts as a secondary shield, protecting your home from potential damage.
4. Effective Moisture Barrier
Most underlays are highly water-resistant, if not waterproof, safeguarding your home against potential water damage.
5. Improved Energy Efficiency
The underlay adds an extra insulation layer, preventing air leaks and potentially reducing energy costs.
6. Guard Against Ice and Water Damage
In areas prone to harsh winters, the underlay acts as a protective barrier against snow, rain, and ice.
7. Protection for the Roof Deck
The underlay shields the roof deck from potential damage, ensuring longevity.
8. Peace of Mind
Knowing that your home is protected by a high-quality underlay offers peace of mind, especially during extreme weather conditions.
