Q1 Is Roof Underlayment Necessary?
A: Underlayment is an important component to the overall roof system as it serves as an extra layer of protection for your roof. Roof underlayment will:
* Protect against moisture penetrating through the roof, resulting in leaks. Add extra insulation to your home to keep it from being drafty.
* Absorb noise from rain or other elements on the roof.
* Ensure that the roofing material laid on it looks uniform and even.
* Keep your roofing warranty valid if applicable.
Q2 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.
Q3 How Long Can Synthetic Roof Underlayment Be Exposed?
A: Within a certain timeframe, synthetic underlayment can be left exposed to the elementsand not be damaged. The time frame depends on the specific manufacturer of the underlayment as each is different. We recommend, roofing underlayment which can be exposed for 6 months to 12months.

In an effort to save money,there are brands of synthetic underlayment that boast about their mil thickness. This canbe misleading though as some of these underlayment have a fuzzy top layer for walkabilitythat's a false indicator of the materials thickness.
