How To Choose Roofing Underlayment?

Roofing underlayment is a crucial component of any residential roofing systems. It’s a protective layer that sits between the roofing material and the roof deck, providing an extra layer of protection against moisture and other elements that can compromise your roof. Various types of underlayment are available, and we’ll provide some tips on choosing the best roofing underlayment for your needs.

Roofing Underlayment

Roofing underlayment is a protective layer between the roof deck and the roofing material. Its primary function is to provide additional protection against moisture and other elements that can compromise the roof’s integrity. Underlayment is typically made of felt, rubber, or synthetic materials like polyethylene or polyester.

The underlayment is an essential component of the roofing system because it provides a waterproof barrier that prevents water from penetrating the roof deck and damaging the underlying structure of the roof. It also provides an additional layer of insulation that helps to keep the home warm in the winter and cool in the summer.

Underlayment is typically installed in two layers. The first layer is installed directly on the roof deck, known as the base layer. The second layer, the cap layer, is installed over the base layer and is typically made of more durable material to provide additional protection against moisture and other elements.

The type of underlayment used depends on several factors, including the climate in the area, the type of roofing material used, and the roof’s slope. In areas with heavy rainfall or snow, waterproof underlayment is necessary to prevent water from seeping into the home. UV-resistant underlayment is necessary to prevent heat damage and cracks in areas with high temperatures and sun exposure.

Consider the Climate

The first thing to consider when choosing roofing underlayment is the climate in your area. Different regions experience different weather patterns; some underlayments are better suited to particular climates than others. For instance, in areas that experience heavy rainfall or snow, a waterproof underlayment is necessary to prevent water from seeping into your home. Alternatively, a UV-resistant underlayment is essential in areas with high temperatures and sun exposure to prevent heat damage and cracking.

Evaluate the Material

Roofing underlayment is made from various materials, including felt, rubber, and synthetic materials. Each material has advantages and disadvantages, so it is essential to evaluate the material before choosing it. For example, felt is a traditional underlayment material that is cheap and easy to install. However, it’s less durable than other materials and more prone to damage. Rubber underlayment is more expensive but is very durable and provides excellent protection against moisture. Synthetic materials, like polyethylene or polyester, are becoming increasingly popular because they balance durability, price, and ease of installation.

Understand the Types of Underlayment

There are two main types of roofing underlayment: synthetic and traditional. Synthetic underlayment is made from polyethylene or polyester and is becoming more popular because it balances durability, price, and ease of installation. Traditional underlayment is typically made of felt and is cheaper than synthetic underlayment. However, it could be more durable and more challenging to install.

Consider the Weight

Another factor to consider when choosing roofing underlayment is weight. Lightweight underlayment is easier to install, putting less stress on the roof deck. However, it’s less durable than heavier underlayment and may not provide as much protection against moisture. Heavy underlayment is more durable and provides better protection against moisture. However, installing is more challenging and can put more stress on the roof deck.

Evaluate the Warranty

When purchasing roofing underlayment, it’s crucial to evaluate the warranty. A good warranty will provide peace of mind and protect your investment. Look for a warranty that covers the underlayment for at least 15 to 20 years. Some manufacturers offer up to 50 years of warranties, which can be a good option if you plan to stay in your home for an extended period.

Check the Code Requirements

It’s also essential to check the code requirements in your area. Depending on the climate and other factors, the building codes in your area may dictate which type of underlayment is required. Be sure to check with your local building department to ensure that you choose an underlayment that meets the code requirements in your area.

Consult with a Professional

Choosing the proper roofing underlayment can be daunting, especially if you must familiarize yourself with the different types and materials. If you need help deciding which underlayment to choose, consult a professional roofing contractor. They can help you evaluate your needs and recommend the best type of underlayment for your home.
