Everyone needs a good pair of underlayment.

Felt underlayment, also known as roofing felt, is a protective layer installed between the roofing deck and the shingles. It is typically made from a combination of asphalt, polyester, cellulose, or fiberglass. Its primary purpose is to provide an additional barrier against water and weather, protecting the roof structure from leaks and damage. The history of felt underlayment dates back to the early 19th century, when builders began using tar paper, a rudimentary form of felt, to enhance roof durability. By the mid-20th century, advancements in manufacturing led to the development of more refined and robust versions of felt underlayment. This evolution has continued, with modern iterations offering improved moisture resistance, durability, and ease of installation, making felt underlayment a standard component in contemporary roofing systems.

Synthetic nail-down roof underlayment is a modern alternative to traditional felt, designed to offer superior performance and durability. Composed of lightweight, high-strength polymers, it provides exceptional resistance to tearing, UV damage, and moisture. This type of underlayment is typically installed using nails or staples, ensuring a secure fit under various roofing materials, including asphalt shingles, metal, and tiles. One of its key advantages is its ease of installation, as it often comes in larger rolls, reducing the number of seams and making the process quicker and more efficient. Additionally, synthetic nail-down underlayment is known for its longer lifespan compared to traditional felt, making it a cost-effective choice for homeowners and contractors seeking enhanced protection and longevity for their roofing systems.

Peel-and-stick roofing underlayment is a high-performance solution designed for enhanced waterproofing and ease of installation. Featuring an adhesive backing, it adheres directly to the roof deck, eliminating the need for nails or staples. This self-adhering characteristic ensures a tight, secure bond, effectively sealing around fasteners and preventing water infiltration. Ideal for areas prone to extreme weather conditions, peel-and-stick underlayment provides superior protection against wind-driven rain, ice dams, and leaks. It is typically composed of rubberized asphalt or butyl-based materials, offering excellent flexibility and durability. This underlayment is particularly favored for its ability to form a continuous, watertight barrier, making it an excellent choice for safeguarding roofs in regions with harsh climates or complex roofing geometries.
