SYNSTEP 100 is significantly more durable, resistant to tearing, and offers better UV protection compared to traditional felt. When installed correctly and protected by the primary roofing material, synthetic underlayment can last as long as the roof itself, often between 20 to 50 years. SYNSTEP 100 underlayment provides a durable, water-resistant barrier that protects the roof deck, contributing to the overall longevity and performance of the roof system.

SYNSTEP 100 comes with a 30-year limited warranty covering manufacturing defects and product performance under normal conditions, but excludes issues from improper installation, natural disasters, or lack of maintenance. Proper installation by a certified professional, adherence to the manufacturer’s guidelines, and documented periodic inspections are required. Warranty coverage decreases over time and may be voided by improper installation or maintenance.

While some U.S. roofing underlayment manufacturers may offer warranties of up to 50 years, these warranties can sometimes be misleading. The actual lifespan of roofing products depends on various factors. It's crucial to thoroughly read the warranty details and ensure all necessary maintenance and documentation are in place to maintain the warranty.

Measuring synthetic underlayment thickness with a digital micrometer can be challenging due to potential variations caused by scrim reinforcement. Typically, synthetic underlayment is measured by weight per square meter (GSM) or per square foot. If customers measure the thickness, they should use calibrated micrometers according to ASTM D 1777 standard and check the thickness at 10 points along the width of the membrane. Due to the unstable structure of nonwoven materials, some areas may be thinner or thicker. Additionally, some market players may increase their thickness without meeting proper regulations. Generally, 100 GSM corresponds to roughly 7 mils in nominal thickness, while 85 GSM corresponds to roughly 6 mils, 108 GSM corresponds to roughly 7.5 mils. One mil equals 0.0254 mm.
