VB Synthetics VB Defender Roof Underlayment 4'x250'
VB Synthetics’s VB Defender is a synthetic roofing felt underlayment that is critical for helping to prevent wind-driven rain from infiltrating under the roof’s shingles and potentially damaging the home’s structure and interior. It is extremely durable and will not absorb moisture which will help prevent wrinkling that can possibly telegraph through the shingles. Additionally, compared to black asphalt felts, VB Defender is designed to provide a cooler working surface which enhances walkability.
