Engineered for Maximum Protection, Durability & Efficiency

Welcome to Adcos, a premier manufacturer and supplier of highly engineered synthetic roofing underlayment. Designed specifically for sloped roofs, our mechanically attached, coated woven synthetic underlayment provides an impenetrable moisture barrier and unmatched product performance.

Whether you are navigating heavy roof traffic or adverse weather conditions, Adcos delivers a roofing solution that keeps your projects secure, dry, and intact from day one to completion.

The Adcos Advantage: Built for Productivity

We understand that time is money for roofing contractors and suppliers. That is why Adcos synthetic underlayment is manufactured to be lighter, wider, and stronger than traditional asphalt felt.

Do More in Less Time

Our extended run lengths and wider widths mean fewer laps, fewer cuts, and effortless roll handling.

Labor Savings

Faster, accurate installation translates to reduced labor costs so your crew can move on to the next job faster.

Inventory Efficiency

Exceptional coverage per roll allows you to inventory fewer rolls while completing larger projects.

Key Features & Technical Insights

Our state-of-the-art manufacturing process guarantees an underlayment that outperforms standard #30 asphalt felt across all metrics:

Exceptionally Strong

Engineered with up to 600% greater tear strength than standard felt, offering superior wind resistance and preventing blow-offs and tears around fasteners.

Dynamic Steep-Slope Traction

Safety comes first. Our underlayment features a specialized fiber-grip anti-slip top coating and an advanced backside non-slip surface to ensure a secure walking surface on steep pitches.

All-Weather Performance

Adcos underlayment features exceptional low-temperature flexibility—meaning it won’t become stiff or hard to unroll in the freezing cold, nor will it dry out, crack, or leach oils in extreme summer heat.

100% Water, Air & Mold Resistant

Our 100% synthetic construction will not absorb water, wrinkle, warp, or buckle. It remains completely impervious to mold growth and rot.

Breathable Technology

Designed to help prevent inside moisture from becoming trapped within your roofing system, preventing long-term structural damage.

UV Stabilized

Formulated with UV-resistant polypropylene construction, allowing the underlayment to be left exposed on a roof deck for up to 180 days without degradation.

Lightweight & Fast Installation

Our 48″ (1.22 m) wide rolls provide 33% more coverage per course than traditional 36″ felt. Weighing in at approximately 43 lbs (19.5 kg) per roll, it is significantly lighter and easier to hoist up a ladder.
