Roof Underlayments: Why Perkins Chose Polyglass Polystick
Perkins explains why a Polyglass Polystick underlayment is now its main choice for shingle roofs even though it costs more than some alternatives, and notes that product approvals and local code decide which underlayments can be used under metal roofs.
Compare the specified underlayment, not only the total
Perkins discusses its Polyglass Polystick choice for shingle roofs in this short. Treat that as the subject of this video, rather than an assumption that every proposal uses the same product. Ask what your own quote includes and how the contractor selected it. For metal roofing, the video also points to product approvals and local code as part of the selection. Keep the product name and assembly details in the written scope so a price comparison does not hide a change in materials.
