1. Waterproofing: Underlayment acts as a waterproof barrier between the roof deck and the roofing material, preventing water infiltration and protecting the underlying structure from moisture damage.
2. Protection: Underlayment provides an additional layer of protection against leaks, wind-driven rain, snow, ice dams, and other weather elements that can compromise the integrity of your roof.
3. Temperature Regulation: Certain types of underlayment offer thermal insulation properties, helping regulate temperature fluctuations and improve energy efficiency in your home.
4. Enhanced Roofing Performance: By reducing moisture buildup, underlayment contributes to the overall performance of the roofing system, including improved ventilation, reduced mold and mildew growth, and extended roof lifespan.

Benefits of Underlayment in Roofing Systems

Investing in high-quality underlayment as part of your roofing system offers numerous benefits that contribute to the long-term protection and performance of your home:

1. Waterproofing: Underlayment effectively seals seams, joints, and penetrations on the roof, preventing water penetration and potential water damage to the interior of your home.
2. Durability: Durable underlayment materials, such as synthetic membranes or rubberized asphalt, withstand harsh weather conditions, UV exposure, and mechanical damage, ensuring long-lasting protection.
3. Ice and Water Shield: Some underlayment products, such as ice and water shield membranes, provide exceptional protection against ice dams, snow melt, and water backup, particularly in cold climates like St Helens.
4. Improved Indoor Comfort: By reducing heat loss and maintaining consistent temperatures, certain underlayment types contribute to improved indoor comfort and energy efficiency, leading to lower utility bills.
5. Extended Roof Lifespan: Properly installed and maintained underlayment enhances the overall durability and performance of your roof, extending its lifespan and minimizing the need for premature repairs or replacements.

Types of Underlayment

There are several types of underlayment available for roofing systems, each offering unique features, benefits, and suitability for different roofing materials and climates:

1. Asphalt-saturated Felt: Traditional felt underlayment is made from organic or fiberglass materials saturated with asphalt. It provides basic waterproofing and is commonly used with asphalt shingles.
2. Synthetic Underlayment: Synthetic underlayment is made from polypropylene or polyester materials, offering superior durability, tear resistance, and UV protection. It is lightweight, easy to install, and suitable for various roofing materials.
3. Rubberized Asphalt: Rubberized asphalt underlayment combines asphalt with rubber or polymer modifiers for enhanced flexibility, adhesion, and waterproofing properties. It is ideal for high-temperature and high-moisture environments.
4. Ice and Water Shield: Ice and water shield membranes are self-adhesive, rubberized underlayments designed specifically for areas prone to ice dams, snow melt, and water backup. They provide an extra layer of protection in vulnerable roof sections.

Choosing the right type of underlayment depends on factors such as climate, roofing material, slope, and local building codes. Our team of experienced roofers in St Helens can help you select and install the most suitable underlayment for your roofing system.
