In this article, we’ll explore the various types of roof felt and help you choose the right one for your roofing needs. So, let’s dive in!

Introduction to Roof Felt

Roof felt, also known as roofing underlayment or tar paper, is a thin layer of material that is installed between the roof deck and shingles. It serves as an additional barrier against moisture and helps to protect your home from water damage.

Roof felt has been used in roofing systems for over a century and has evolved into different types with varying features.

Asphalt-saturated felt was the first type of roof felt introduced in the market. It consists of organic or fiberglass matting that is saturated with asphalt to make it waterproof.

Rubberized asphalt came next, which added rubber polymers to improve its flexibility and durability.

Synthetic roof felts are relatively new but have gained popularity due to their superior performance compared to traditional felts. They are made from synthetic materials such as polypropylene or polyester fibers coated with asphalt for waterproofing.

Choosing the right type of roof felt depends on various factors such as climate conditions, budget constraints, personal preferences among others.

Asphalt-Saturated Felt

It’s made from a base material of organic or fiberglass mat that’s saturated with asphalt to make it waterproof. The asphalt coating gives the felt its characteristic black color and makes it resistant to water and UV rays.

One advantage of using asphalt-saturated felt is its affordability compared to other types of roof underlayment. It’s also easy to install since it can be nailed down directly onto the roof deck without any special equipment or tools.

However, one disadvantage is that this type of felts tends to dry out over time due to exposure from sunlight and heat which may cause cracking leading water penetration into your home causing damage such as mold growth on walls or ceilings.

Rubberized Asphalt

It is made by adding recycled rubber to the asphalt mix, which enhances its strength and resistance to weathering. Rubberized asphalt also provides better insulation than traditional felt, making it an excellent choice for homes located in areas with extreme temperatures.

One of the significant advantages of rubberized asphalt is that it can be used on both low-slope and steep-slope roofs. Its flexibility allows it to conform easily around corners, edges, and other irregular shapes without cracking or tearing.

Another benefit of using rubberized asphalt as your roofing underlayment material is that it helps reduce noise transmission from outside sources such as rain or hail hitting the roof surface. This feature makes it ideal for homes located near busy roads or airports where noise pollution can be a problem.

However, like any roofing material, there are some disadvantages associated with using rubberized asphalt as well. One potential drawback could be its cost compared to traditional felt options; however many homeowners find this investment worthwhile given their long-lasting benefits.

Synthetic Roof Felts

These are made from materials like fiberglass or polyester and coated with asphalt to make them waterproof. Synthetic roof felts offer several advantages over traditional felt, including better tear resistance, UV protection, and improved moisture control.

One of the most significant benefits of synthetic roof felts is their longevity. They can last up to three times longer than traditional felt underlayment due to their superior strength and durability.

They are lightweight yet strong enough to withstand harsh weather conditions such as heavy rain or snowfall.

Another advantage is that they come in larger rolls compared to traditional felt underlayment which means fewer seams during installation resulting in less chance of water penetration through joints.

However, it’s important not just choosing any type of synthetic roofing material but one that meets your specific needs based on factors such as climate zone where your home is located among others.

Choosing the Right Roof Felt

The type of roofing material you have, your budget, and the climate in your area are all important considerations.
