Choosing Between Synthetic and Felt Roofing Underlayment

When planning a roof replacement or repair, homeowners often prioritize the outer materials. However, the underlayment is just as essential for protecting the structure from possible storm damage. In this article, M&A Exterior Home Improvement compares synthetic and felt underlayment to help you make an informed decision for your home.

A Primer on Roofing Underlayment

Roofing underlayment is the barrier installed between the roof deck and the shingles. This hidden yet essential layer protects against moisture, which can cause mold and other water-related damage.

Synthetic Underlayment

Introduced in the early 2000s, synthetic underlayment is a product of modern technological advances in the roofing industry. It is fabricated from polymers like polyethylene or polypropylene, contributing to its incredible durability and resistance to tearing.

Synthetic underlayment presents undeniable benefits for homes in regions where the weather can be a mix of sun and rain. Its resistance to UV exposure and moisture makes it a solid choice for long-term protection. Moreover, synthetic underlayment has a lighter weight, making it easier to handle during the installation process. This could mean lower labor costs and more affordable roofing services.

Although the initial investment for synthetic underlayment is higher, its durability and minimal maintenance can make it more cost-effective in the long run. Homeowners may appreciate this choice for its extended lifespan, which can range between 25 to 30 years.

Felt Underlayment

Felt underlayment comes in different thicknesses and durability levels. Also known as asphalt-saturated felt, it’s been used for years and absorbs moisture well. If your budget is a primary concern or you are looking for a more traditional option, high-quality felt may be the way to go. However, take note that it can be heavier, posing challenges during installation.
