Protect What’s Inside by Controlling Roof Condensation
Dripstop™ Protects Your Roof & Everything Under It From Water Damage Caused by Condensation.
What is Dripstop why do you need it.
Dripstop is a factory-applied anti-condensation membrane for corrugated/metal roofing used in non-climate-controlled buildings. Applied to the underside of panels during manufacturing, Dripstop acts like a sponge. When warm, humid interior air meets the cool metal roof and would normally form drips, the Dripstop captures and holds moisture. As conditions warm, that moisture harmlessly evaporates back out into the atmosphere. The result is a dry interior—without messy roof drips—plus added protection for the panel and a simpler, more economical alternative to insulated panel systems.

A Simple Upgrade That Protects Against Major Damage and Expense
The best time to address condensation is before you put up a building. After construction, options become limited and extremely costly. Adding condensation control requires only a modest additional investment during construction or reroofing, but the payoff is significant. Dripstop protects your roof, safeguards your building’s contents and extends the life of your investment. Pricing varies based on factors such as profile and size.

What exactly is Dripstop and how does it work?
Dripstop® is a factory-applied, high-tech non-woven membrane installed under metal roof panels. It absorbs condensation droplets as they form and holds the moisture until humidity levels drop, allowing it to evaporate back into the air—preventing dripping.
Does it still allow condensation to form?
Dripstop doesn’t stop condensation entirely—it traps it safely inside the membrane and allows it to evaporate instead of dripping. While unlikely some condensation and dripping could occur.
Where can Dripstop be used?
It’s ideal for uninsulated metal roofs across a wide variety of structures—farms, storage facilities, industrial halls, garages, and warehouses.
What makes Dripstop durable and easy
to maintain?
Made of tear‑proof PES fibers, it’s non-combustible (Class A2 – s1, d0) and resistant to bacteria, mold, and corrosion.
* It requires little to no maintenance—simply hose it off if needed.
Does it help with noise?
Yes. Dripstop can reduce rain and impact noise by up to 2 dB (a 12% perceived reduction) and comes in specialized versions—like Soundcontrol—for enhanced acoustic performance.
Is it environmentally friendly?
Absolutely. Dripstop is chemical-free, can be manufactured using recycled PET, and retains its effectiveness for the lifetime of the metal roof.
How much does it cost?
While costs can vary by metal profile and installation details, Dripstop generally adds about **\$0.25 per square foot** of roof area—around **\$1,200 for a 5,000 sq. ft. roof**. A modest upfront investment that saves significantly on future damage and maintenance.
How does it impact installation?
Because it’s factory-applied, Dripstop helps roof panels install faster (up to 30% quicker), reduces labor, and improves job-site safety with no loose insulation to manage.
How long does the warranty last?
Dripstop comes an adhesion warranty in addition there is the manufacturer’s long-term warranty—often 40 years—providing peace of mind and lasting protection.
How does Dripstop compare to
traditional insulation like single
or double bubble?
Bubble insulation mainly acts as a vapor barrier and offers some insulation value, while Dripstop is designed specifically to control condensation by absorbing and releasing moisture. If you need insulation and heat resistance, bubble products may be a better fit. If your main concern is stopping drips and protecting against moisture damage, Dripstop is the more effective choice.
