Roofing is an essential part of your home, and its longevity and durability depend on various factors, from the quality of shingles to the underlayment. Choosing the right underlayment for your roof can help you prevent leaks, improve insulation, and extend the lifespan of your roofing system. When it comes to underlayment, two options are widely available in the market- synthetic and felt. In this blog post, we will discuss the pros and cons of both synthetic and felt roofing underlayment to help you make an informed decision.
Synthetic Roofing Underlayment:
Synthetic roofing underlayment is made of polypropylene or polyester materials that offer excellent protection against water, weather, and other elements. Here are some pros and cons of synthetic roofing underlayment:
Pros:
- Synthetic underlayment is highly durable and can withstand harsh weather conditions, including extreme heat and cold.
- It is lightweight and easy to install, making it a preferred option for DIYers.
- Synthetic underlayment is an eco-friendly option that doesn't contain asphalt and felt, which are non-renewable materials.
- It is resistant to mold and mildew growth, reducing the chances of fungal infestation and rot.
Cons:
- Synthetic underlayment is more expensive than felt underlayment.
- It doesn't provide the same level of resistance to tearing as felt underlayment and may be prone to punctures and tears during installation.
- Synthetic underlayment can be slippery, making it difficult to walk on during installation or repair.
Felt Roofing Underlayment:
Felt roofing underlayment is an organic option made of asphalt-saturated paper or fiberglass. Here are some pros and cons of felt roofing underlayment:
Pros:
- Felt underlayment is a more affordable option than synthetic underlayment.
- It offers a high level of water resistance and can protect your roof from leaks and other water damage.
- Felt underlayment is less slippery than synthetic underlayment and provides a better surface for walking during installation or repair.
- It can be easily cut and shaped to fit around vents, chimneys, and other roofing features.
Cons:
- Felt underlayment is prone to tearing, which can lead to leaks and other damages.
- It may not provide the same level of insulation as synthetic underlayment and may not be ideal for cold-weather conditions.
- Felt underlayment can absorb moisture, which can lead to mold and mildew growth and may reduce its lifespan.
- It contains asphalt, which is a non-renewable resource and may not be environment friendly.
Choosing the right underlayment for your roofing system depends on your budget, the climate you live in, and the level of protection you're looking for. While synthetic underlayment is a more durable and eco-friendly option, it comes at a higher cost. Felt underlayment is an affordable and conventional option that works well for most roofing systems but may not provide the same level of protection as synthetic underlayment. It's essential to consult with a professional roofer to determine the best option for your roofing system. Ultimately, selecting the right underlayment will help you improve the longevity and durability of your roof, protecting your home and your family.
