The ZIP System Peel and Stick Underlayment is designed to protect metal roofs from water damage, especially in vulnerable spots like eaves and valleys where ice dams and wind-driven rain are common. It’s made with a rubberized asphalt material that creates a strong, waterproof seal around nails, which helps prevent leaks effectively. The product is quite thin at 0.04 inches, making it lightweight and easy to handle during installation, and its slip-resistant surface adds safety while working on the roof.

It can withstand temperatures up to 260°F, which is helpful if you live in a hot climate or if the roof surface gets very warm. While UV resistance isn’t specifically mentioned, underlayments like this are typically covered by the metal roofing itself, so long sun exposure is usually not a big concern. The self-adhesive backing makes it quicker to install compared to traditional felt paper, saving time and effort.

One possible downside is that it may be heavier than some alternatives at 51 pounds due to its dense material, though this weight also suggests durability. This underlayment meets building codes for ice and water barriers, giving extra confidence in its reliability. If you want an easy-to-apply, waterproof layer to add protection under your metal roof, this product offers solid performance with a focus on durability and temperature tolerance.

Buying Guide for the Best Underlayment For Metal Roof

Choosing the right underlayment for your metal roof is crucial for ensuring the longevity and performance of your roofing system. Underlayment acts as a protective barrier between the metal roof and the roof deck, providing additional protection against moisture, heat, and other environmental factors. Understanding the key specifications and how they relate to your specific needs will help you make an informed decision.
Material TypeThe material type of the underlayment is important because it determines the durability, water resistance, and overall performance of the underlayment. Common materials include asphalt-saturated felt, synthetic underlayment, and rubberized asphalt. Asphalt-saturated felt is traditional and cost-effective but less durable. Synthetic underlayment is lightweight, tear-resistant, and offers superior water resistance. Rubberized asphalt provides excellent waterproofing and is self-sealing around nails. Choose the material based on the climate and specific needs of your roof.
ThicknessThickness of the underlayment affects its durability and protective qualities. Thicker underlayments generally offer better protection against moisture and physical damage. Underlayments typically range from 15 to 45 mils in thickness. For areas with heavy rainfall or snow, a thicker underlayment is advisable. For milder climates, a thinner underlayment may suffice. Consider the environmental conditions and the level of protection you need when selecting the thickness.
Water ResistanceWater resistance is a critical spec because it determines how well the underlayment can prevent water from penetrating the roof deck. High water resistance is essential in areas prone to heavy rain or snow. Underlayments are rated for their water resistance, with some being fully waterproof and others being water-resistant. Fully waterproof underlayments are ideal for areas with extreme weather conditions, while water-resistant options may be suitable for less severe climates. Assess the typical weather patterns in your area to determine the necessary level of water resistance.
Temperature ToleranceTemperature tolerance indicates the range of temperatures the underlayment can withstand without degrading. This is important for ensuring the underlayment performs well in both hot and cold climates. Underlayments with higher temperature tolerance are better suited for areas with extreme temperature fluctuations. Look for underlayments that can handle the highest and lowest temperatures expected in your region to ensure long-term performance.
UV ResistanceUV resistance is important because it determines how well the underlayment can withstand exposure to sunlight before the metal roof is installed. Prolonged UV exposure can degrade the underlayment, reducing its effectiveness. Underlayments with high UV resistance can be exposed to sunlight for longer periods without damage. If there is a possibility of delayed installation of the metal roof, choose an underlayment with good UV resistance to ensure it remains intact and effective.
Installation EaseEase of installation affects the time and effort required to properly install the underlayment. Some underlayments are designed to be easier to handle and install, with features like peel-and-stick application or pre-marked nailing guides. If you are planning a DIY installation or want to reduce labor costs, look for underlayments that are user-friendly and come with clear installation instructions. Consider your installation capabilities and the complexity of the underlayment when making your choice.
