Synthetic vs. Felt Roofing Underlayment: A Detailed Comparison
Roofing is more than just the visible shingles or tiles. Beneath these protective layers lies the unsung hero of roofing systems: the underlayment. This crucial component acts as a barrier against moisture, ensuring the longevity of your roof and the safety of your home. At Unisource Roofing, we understand the importance of choosing the right underlayment, and in this article, we'll delve deep into the two primary types: Synthetic and Felt.
The Role of Roofing Underlayment
Roofing underlayment serves as a protective layer between the roof's shingles and the deck. Its primary function is to prevent moisture from reaching the wooden structure of the roof, safeguarding it from potential damage.
Delving into Felt Roofing Underlayment
Felt roofing underlayment, a time-tested solution, is produced by saturating paper or fiberglass mat with asphalt. It's predominantly available in two variants: No.15 felt and No.30 felt, with the latter being thicker and more robust.
Advantages:
Cost-Effective: One of the primary reasons homeowners opt for felt underlayment is its affordability.
Drawbacks:
Limited Exposure: Felt underlayment can't be left exposed for extended periods as it may dry out or lose its protective oils.
Tear-Prone: It's susceptible to tearing, especially during installation or in strong winds.
Absorbs Moisture: If exposed to moisture, felt can wrinkle, making it challenging for shingles to lie flat.
Heavier: Its weight makes it cumbersome for roofers to transport and install.
Potential Seams: Due to its weight, there's less material per roll, leading to more seams.
Exploring Synthetic Roofing Underlayment
Synthetic underlayment, made from durable polymers, offers enhanced protection against the elements. Its composition ensures longevity and superior moisture resistance.
Advantages:
Durability: Synthetic underlayment boasts a high tear strength, making it resilient to wear and tear.
Extended Exposure: Some synthetic underlayments can withstand prolonged UV and moisture exposure.
Lightweight: Being lighter than felt, it's easier for roofers to handle and install.
Safety: Many synthetic underlayments offer slip-resistant surfaces, ensuring safer installations.
Moisture Resistant: Unlike felt, synthetic underlayments repel water, making them ideal for homes in areas prone to heavy rainfall.
Drawbacks:
Cost: The primary downside is the cost, which can be higher than felt. However, the long-term benefits often justify the initial investment.
