Planning a Roof Replacement in Northeast Ohio?
Synthetic roof underlayment is a protective layer installed over the roof deck and beneath asphalt shingles or another approved roof covering.
Most homeowners never see this part of the roofing system after installation, but during a complete roof replacement it plays an important role in providing secondary protection beneath the finished roofing material.
For Northeast Ohio homeowners, it is also important to understand that synthetic underlayment is not the same product as ice-and-water barrier.
Each material has a different purpose within the roofing system.
This guide explains what synthetic roof underlayment is, how it compares with traditional roofing felt, where ice-and-water protection fits into a Northeast Ohio roof and what homeowners should look for during a roof replacement. 440.235.3124
When it comes to roofing, every component plays a crucial role in ensuring longevity, durability, and overall protection for your home. One of the most important but often overlooked elements is the underlayment. Traditional roofing felt has long been used as a protective barrier, but in recent years, synthetic felt has become the go-to choice for contractors and homeowners alike. At S&K Construction And Remodeling LLC, we specialize in high-quality roofing solutions, including the installation of premium synthetic felt underlayment. In this guide, we’ll explore the benefits, types, and installation of synthetic felt, and why it’s a superior choice for your roofing project.
What is Synthetic Felt Roofing Underlayment?
Synthetic felt roofing underlayment is a high-performance, durable, and water-resistant material placed between the roof deck and shingles. Unlike traditional asphalt-saturated felt, synthetic underlayment is made from woven polyethylene or polypropylene, making it lighter, stronger, and more resistant to weather elements.
Is Synthetic Roof Underlayment Waterproof?
Synthetic roof underlayment should not automatically be described as waterproof.
Many synthetic products are designed to resist water and provide secondary protection beneath the roof covering, but the finished shingles or other approved roof covering remain the primary exterior weather surface.
Product specifications vary.
Homeowners should not assume that an exposed synthetic underlayment can safely function as a temporary finished roof during prolonged rain, snow or severe weather.
The allowable exposure period and installation requirements should always be checked for the exact product being used.
Synthetic Underlayment vs. Ice-and-Water Barrier
Synthetic roof underlayment and ice-and-water barrier are not the same material.
Synthetic underlayment is generally installed across large portions of the roof deck beneath the finished roof covering. It provides a secondary layer of water resistance beneath the shingles.
Ice-and-water barrier is typically a self-adhering membrane installed in specific vulnerable areas of the roofing system.
Depending on the roof design and applicable requirements, those areas can include portions of the roof near:
- Eaves
- Valleys
- Certain roof penetrations
- Other vulnerable roof details
For Northeast Ohio homes, protection near the eaves is particularly important because snow and ice can create winter water-backup conditions.
A synthetic field underlayment should therefore not be described as a replacement for a required ice-barrier membrane.
The exact materials and installation should comply with applicable requirements and the roofing manufacturer’s instructions.
Synthetic Roof Underlayment for Northeast Ohio Homes
A Northeast Ohio roof may experience:
- Lake-effect snow
- Ice
- Freeze-thaw cycles
- Heavy rain
- Strong winds
- Hail
- Summer heat
Synthetic underlayment is one component of the complete roofing system used to manage those conditions.
However, a durable roof depends on much more than underlayment alone.
A complete asphalt shingle roof can include:
- Solid roof decking
- Ice-and-water protection
- Synthetic or other approved underlayment
- Drip edge
- Starter shingles
- Asphalt shingles
- Valleys
- Flashing
- Pipe boots and roof penetrations
- Hip-and-ridge shingles
- Attic ventilation
These components need to work together.
Installing premium synthetic underlayment does not compensate for damaged decking, poorly installed flashing or other roofing defects.
Advantages of Synthetic Felt Over Traditional Roofing Felt
If you’re considering a new roof or a replacement, synthetic felt offers several advantages over traditional felt underlayment:
1. Superior Durability
- Synthetic felt is tear-resistant, making it a more reliable option for withstanding harsh weather conditions, heavy foot traffic, and installation stress.
- Unlike traditional felt, which can become brittle over time, synthetic felt maintains its integrity longer.
2. Water Resistance and Moisture Protection
- Traditional felt can absorb water, leading to potential mold growth and weakening over time. Synthetic felt, however, repels water, keeping your roof deck dry and structurally sound.
- It provides an extra layer of protection against leaks and ice dams.
3. Lightweight and Easy to Install
- Synthetic underlayment is much lighter than traditional felt, making it easier to handle and install.
- Larger rolls cover more area per roll, reducing the need for frequent overlaps and seams.
4. UV Resistance
- Many synthetic felt options offer UV protection, allowing them to be exposed to sunlight for longer periods without breaking down. This is beneficial if roofing materials aren’t installed immediately.
5. Increased Safety
- Synthetic felt provides better traction for roofers during installation, reducing the risk of slips and falls.
- Some brands incorporate slip-resistant coatings for added worker safety.
6. Extended Roof Lifespan
- By offering superior protection against moisture and UV exposure, synthetic felt helps extend the lifespan of your entire roofing system.
Types of Synthetic Felt Roofing Underlayment
Several types of synthetic underlayment are available, each designed to meet specific needs. Here are the most common types:
1. Standard Synthetic Felt
- Designed as a general-purpose underlayment, this type offers solid water resistance and durability.
- Suitable for most residential roofing applications.
2. High-Temperature Synthetic Felt
- Ideal for metal and tile roofs where high temperatures can degrade traditional underlayment.
- Made with materials that can withstand prolonged exposure to heat.
3. Breathable Synthetic Felt
- Allows moisture vapor to escape while maintaining water resistance.
- Helps prevent condensation buildup, making it ideal for humid climates.
4. Self-Adhering Synthetic Felt
- Features an adhesive backing that sticks directly to the roof deck.
- Provides an added layer of water resistance and is useful in high-wind areas.
The Installation Process of Synthetic Felt
At S&K Construction And Remodeling LLC, we follow a precise installation process to ensure maximum performance and protection for your roof:
Step 1: Roof Deck Preparation
- Before installing the underlayment, we inspect the roof deck for any damage or irregularities.
- Any necessary repairs are made to ensure a smooth, solid surface for the underlayment.
Step 2: Laying Out the Synthetic Felt
- The synthetic felt is rolled out horizontally across the roof deck, starting from the eaves and working upward.
- We ensure proper overlap to create a seamless, watertight barrier.
Step 3: Securing the Underlayment
- Depending on the type of synthetic felt used, we either staple, nail, or adhere the material in place.
- In high-wind areas, cap nails or plastic caps may be used for extra holding power.
Step 4: Flashing and Additional Sealing
- We install flashing around roof penetrations like vents, chimneys, and skylights to prevent water intrusion.
- Additional sealing measures are taken to ensure a fully protected roof.
Step 5: Final Inspection
- Our team conducts a thorough inspection to verify proper installation before proceeding with shingle installation.
