When you’re considering a roof replacement or installation, one essential component you may encounter is roof felt. It plays a crucial role in protecting your home, especially in locations like West Palm Beach, Florida, where weather conditions can be unpredictable. But what exactly goes under roof felt, and why is it so important for your home’s protection?
With Star Roofing, we’ll dive deep into the layers and materials involved in roofing, with a particular focus on what goes under roof felt, its purpose, and why it’s essential for homeowners in West Palm Beach to understand its role. We’ll also discuss the importance of proper installation and maintenance to ensure a long-lasting roof.
What is Roof Felt?
Roof felt, also known as roofing underlayment, is a layer of material placed between the roof deck (the wooden surface) and the shingles or other roof coverings. Its primary purpose is to provide a protective barrier that prevents moisture from penetrating the roof, which could lead to leaks, mold, and water damage inside your home.
In areas like West Palm Beach, Florida, which experience heavy rain, humidity, and even hurricanes, roof felt becomes an even more critical component of your roofing system. Without this protective layer, your home would be vulnerable to severe weather conditions, leading to costly damage.
What Goes Under Roof Felt?
The layer directly beneath the roof felt is typically the roof deck or sheathing, which is made of wood, plywood, or oriented strand board (OSB). The roof deck serves as the foundation for the roof and is essential for supporting the rest of the roofing system.
1. Roof Deck (Sheathing):
As mentioned, the roof deck is the surface directly under the roof felt. It’s usually constructed from wood or synthetic materials that provide structural support for the roof. This layer is important because it holds the entire roofing system in place, including the shingles or other covering materials.
In West Palm Beach, homes may have different types of roof decks depending on their age and construction, so it’s important to consult with a local roofing contractor who can assess the condition of your deck before installing roof felt.
2. Insulation:
While insulation isn’t always placed directly under the roof felt, it is an essential part of the roof assembly in many homes. In areas with high humidity like West Palm Beach, proper insulation helps regulate temperature and prevent moisture buildup in the attic space. Insulation is typically installed on the attic floor or between the roof rafters, and it can also help improve energy efficiency by keeping the home cooler in summer and warmer in winter.
Insulation works hand-in-hand with roof felt to prevent water vapor from causing damage to the roof deck or the interior of the home. It’s crucial to ensure that insulation is properly installed to avoid condensation that could lead to mold growth.
3. Vapor Barrier:
A vapor barrier is often used under the roof deck and above the insulation to prevent moisture from moving into the attic space. This is especially important in coastal areas like West Palm Beach, where high humidity levels can create the perfect environment for mold and mildew growth.
A vapor barrier, such as a plastic sheet or reflective material, helps keep moisture from entering the attic, which could damage the roof structure and insulation. When combined with roof felt, the vapor barrier provides an additional layer of protection against water infiltration.
The Importance of Roof Felt in West Palm Beach
Roof felt is particularly important for homes in areas like West Palm Beach, where the climate can pose challenges to roof longevity. Due to the region’s tropical climate, with frequent afternoon showers, high humidity, and the potential for hurricanes, having an effective underlayment is essential for keeping your home safe and dry.
When choosing roof felt, you’ll want to consider the material’s durability and weather resistance. In West Palm Beach, fiberglass-based roof felt is often preferred because it offers better moisture resistance and is less likely to break down over time. It’s also important to ensure that the roof felt you choose complies with local building codes, which are designed to ensure that your roof can withstand the unique weather conditions of the area.
Types of Roof Felt
There are two primary types of roof felt: asphalt-saturated felt and synthetic roof underlayment.
1. Asphalt-Saturated Felt:
This is the traditional form of roof felt, made from organic felt that’s saturated with asphalt to make it waterproof. It’s still commonly used in many areas, including West Palm Beach, because it provides a reliable moisture barrier. However, it tends to be heavier than synthetic options and can deteriorate over time when exposed to prolonged moisture.
2. Synthetic Roof Underlayment:
Synthetic roofing felt is made from polypropylene or polyester and is designed to be more durable and resistant to UV rays and moisture compared to asphalt-saturated felt. It’s a great option for homeowners in West Palm Beach, Florida, as it can better withstand the intense sun and humidity typical of the region. Synthetic underlayment is also lighter, making it easier to install.
Proper Installation of Roof Felt
Ensuring that roof felt is properly installed is crucial for its effectiveness in protecting your home. In West Palm Beach, the roof felt needs to be applied securely to prevent any gaps or areas where water could infiltrate.
When installing roof felt, roofing contractors typically follow these steps:
- Prepare the Roof Deck: Ensure the roof deck is clean, dry, and free from any debris that could interfere with the installation.
- Apply a Layer of Roof Felt: Start at the eaves and work your way up the roof, overlapping each layer by several inches to ensure complete coverage. The roof felt should be laid smoothly to avoid any wrinkles or air pockets.
- Install Flashing and Shingles: After the roof felt is in place, flashing is installed around the roof edges and valleys to further prevent water from seeping in. Finally, shingles or other roofing materials are applied over the felt to complete the roofing system.
Maintaining Roof Felt and Preventing Damage
While roof felt is built to last, it’s essential to maintain your roof regularly to ensure its longevity. Here are some maintenance tips for homeowners in West Palm Beach:
- Inspect Your Roof Regularly: Check for any signs of damage, such as missing shingles, cracks, or signs of water infiltration. It’s a good idea to have your roof inspected at least once a year, especially after major storms.
- Clean Gutters and Downspouts: Clogged gutters can cause water to pool on the roof, leading to potential leaks and damage. Clean your gutters regularly to ensure proper drainage.
- Address Leaks Immediately: If you notice any leaks or water stains inside your home, contact a roofing professional right away to assess the damage and prevent further issues.
Conclusion
Understanding what goes under roof felt and how it contributes to the overall roofing system is essential for homeowners in West Palm Beach, Florida. Roof felt acts as a critical layer of protection against moisture, helping to prevent water damage and ensuring the longevity of your roof. By selecting the right materials and ensuring proper installation, you can safeguard your home against the elements and enjoy peace of mind knowing that your roof is built to withstand the challenging weather conditions typical of the area.
Whether you’re planning a new roof installation or replacing an old one, make sure you consult with a local roofing expert in West Palm Beach to ensure your roof is properly protected. With the right underlayment, you can rest easy knowing your home is secure.
