Product Q&A

Q:Is Roof Underlayment Necessary?

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.

Q:What Is Synthetic Roof Underlayment?

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:How Long Can Synthetic Roof Underlayment Be Exposed?

Within a certain timeframe, synthetic underlayment can be left exposed to the elements and 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 12 months.

Q:Synthetic Underlayment Cost vs. Felt Underlayment Cost

Synthetic is a higher quality product but also comes with a higher cost. * Non adhesive synthetic roof underlayment costs 17 cents to 25 cents per square foot * Self adhering underlayment cost 50 cents to 75 cents per square foot * Felt roof underlayment costs 5 cents to 10 cents per square foot.

Q:Is Synthetic Roof Underlayment Better Than Felt Underlayment?

Synthetic roof underlayment is the most preferred form of underlayment material for its strength and tear resistance. Synthetic was actually created to be a product that solved the problems that felt underlayment, or roofing felt, has. For years, felt was the go-to material to use for roofing underlayment. Only within the last two decades has synthetic underlayment hit the market as an improved product that would not have the problems with felt.
