Product Advantage

Won't absorb water.

Synthetics repel water while felt products absorb water. Most homeowners like the idea of having a product that sheds water serve
as their secondary water protection barrier on their roof instead of a sponge.

Enhanced walkability.

Synthetic underlayment is engineered to provide a more secure walking surface. The enhanced slip-resistant surface creates better traction and allows crews to move easier, even on steep slopes.

UV resistance.

Stands up to the effects of UV rays for up to 3 months of worry-free exposure

Lighter than felt.

A single roll of Operfect™ Synthetic Underlayment contains 1000 square feet but weighs only 20 to 26 lb. It’s easier for your installers to handle.

Stronger than felt.

Operfect™ Synthetic Underlayment is more resistant to tearing and shredding when installers walk on it. Plus it’s coated top and bottom with tough polyolefin for superior weather-resistance.

More flexible, even in cold weather.

Operfect™ Synthetic Underlayment is easy to install around vents, dormers, skylights and other typical roof structures. It lays flat without curling and is super
durable.

Manufacturing process

Step 1: adding a surfactant in the waterproof coating, stirring to form a foamed waterproofing agent.
Step 2: apply the foam-like water repellent to the one-sided surface of the cloth.
Step 3: clean up excess foam on the surface of the cloth.
Step 4: sending the fabric into an oven to dry, while making the waterproofing agent plasticized to form a waterproof layer.
Step 5: Surface treatment of the waterproof cloth.

Questions & Answers

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.

Synthetic Underlayment Weight Vs. Mil Thickness

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.

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.
