Q:What Is Synthetic Roof Underlayment?
A:Synthetic underlayment is a roofing accessory composed of laminated polypropylene or polyethylene plastic that goes over the roof deck and serves as an extra layer of protection from the elements for a roofing system. It has excellent durability as the material does not absorb moisture. This makes it the right material to choose when drying in a roof.

Q:Synthetic Underlayment Weight Vs. Mil Thickness
A:Non adhesive synthetic roofing underlayment isn't created equally. There are lots of high quality synthetic roof underlayment brands , but there are also some low quality brands. They try to trick you with a lousy product and fancy marketing. The weight of the synthetic underlayment is a great indication of the quality of the underlayment. The membrane layer is where you get your water proofing and abrasion resistance. In an effort to save money, there are brands of synthetic underlayment that boast about their mil thickness. This can be misleading though as some of these underlayment have a fuzzy top layer for walkability that's a false indicator of the materials thickness.
Q:Is Synthetic Roof Underlayment Better Than Felt Underlayment?
