Dripstop Information
At Cladco Profiles, we strive to ensure that every item works for you, for as long as possible. One way of prolonging the life of your metal roofing, would be to install them with Dripstop®, an additional layer applied to the underside of the sheet to help minimise moisture build-up.
The term ‘roof sweating’ refers to condensation that can occur in uninsulated buildings when excess humidity collects on the reverse of your roof. It typically happens at the start and end of the day due to the sharp differences in temperature inside and outside your roofing system. Water vapour can collect and form droplets, which may fall and cause rot, rust, or damage to flooring.
The Dripstop® layer can be added to 32/1000 box profile, 34/1000 box profile, 13/3 corrugated and 41/1000 tile form sheets. To ensure optimum performance, it is recommended that roofs are pitched to more than 10°. Please get in touch with our sales team on 01837 659901 to enquire about using Dripstop® in your project.
What is Dripstop®?
Dripstop® is an anti-condensation, grey polyester fleece membrane which is applied to the reverse side of sheet profiles to prevent dripping in conditions of high humidity.
The innovative technology traps moisture within specially designed pockets formed inside the membrane. These pockets hold any liquid until it can be released back into the environment within your building as normal humidity.
It’s important not to expose the Dripstop® side of the roof to sunlight, strong wind, or rain to prevent damage. You can find more information in our blog.
How does Dripstop® work?
Condensation forms when there are large changes in temperature, often during the transition from day to night. Dripstop® helps keep condensation safely under control by collecting vapour in small pockets within the membrane — essentially soaking it up like a towel. As the surrounding air warms up again, the collected water evaporates and the fleece membrane dries out.
While it can trap condensation, it cannot completely stop it from occurring. For the Dripstop® to work effectively, your building must have adequate ventilation to allow the membrane to dry as part of its natural cycle. This ensures the material can absorb and release large amounts of condensation without chemical agents, maximising the effectiveness and lifespan of your roof.
This cost-effective solution also helps to maintain structural integrity by providing an extra protective layer within your roofing system. Dripstop® is easy to clean using a hose or pressure washer and is incredibly durable, withstanding environmental temperatures from -40C to +80C.
Dripstop® - safe, reliable, drip-control
Condensation forms when there are large differences in temperature, often during the transition from day to night. Dripstop® keeps condensation safely under control. High air permeability ensures water evaporates completely with rising daytime temperatures and optimal roof ventilation.
The way Dripstop® works is smart and simple. The secret lies in the innovative membrane structure, which maximizes its ability to absorb and release large amounts of condensation.
The material’s smart behaviour is based on a purely physical principle, which means it works 100% without chemical agents. That’s how Dripstop® retains its full effectiveness over the product’s entire useful life.
Where Can Dripstop® Be Used?
Dripstop® is suitable for a wide range of building types and industries where moisture control is essential, including residential, commercial, industrial, and agricultural settings.
Residential
This membrane can be installed on metal roofing sheets to protect roofing systems, lofts, and attics from condensation and water damage.
Commercial
It can help maintain dry interiors in offices, retail spaces, and warehouses by preventing moisture from dripping onto furniture, equipment, or stock.
Industrial
The membrane helps safeguard machinery, work areas, and sensitive environments such as food processing or pharmaceutical facilities from condensation-related moisture.
Agricultural
The added layer keeps barns, poultry houses, and storage sheds dry, protecting livestock, crops, and stored materials from water damage.
Dripstop® and Cladco
If you select Dripstop® on your order, it will be applied during the roll forming process on site at Cladco. This factory-fitting process ensures that by the time your sheets reach you, they’re ready to install.
If you’re unsure whether or not Dripstop® can be applied to your desired roofing sheets, please contact us - we’re happy to help.

Working Conditions
- Dripstop and metal sheet must be conditioned to an operating temperature of +10 °C or higher. It is best if they are both stored in the area where profiling takes place.
- There must be no traces of water, condensation, dust, oil or lubricants, silicone, rust… on the metal sheet surface, as impurities prevent good contact between the glue and the metal sheet and thus adversely affect the profiling process itself and the product quality.
- Surfaces containing plasticizers (e.g. Plastisol) are also not suitable for gluing. Dripstop can be applied to metal sheet with a surface tension of min. 38 mN/m. A test should be performed with a 38 mN/m test marker.
- Even pressure must be ensured over the entire surface between the metal sheet and Dripstop before profiling.
- Coverings with Dripstop must be installed in accordance with applicable building standards and good construction practices.
- Adequate constant ventilation of the roof covering must be ensured in order for Dripstop to dry. This means that the air enters at the gutter and exits through the ridge, thus ensuring a constant flow of air under the roof covering.
- The slope of the gutter must allow constant water drainage.
- In roofs with a slope of less than 10°, it is mandatory to prevent capillary action at the gutter, on the overlaps and in the ridge. A drip edge must be made at the gutter and on the ridge. In slopes exceeding 10°, it is sufficient to prevent capillary action at the gutter and on the overlaps.
Storage
The storage area must be dry and closed, and the product must not be exposed to direct sunlight. The quality of the product will not change over a period of one year from production when stored at temperatures of +5 °C ~ +30 °C.
Warning
- The product is permanently glued and cannot be re-glued once it is removed.
- Do not expose roofing sides with Dripstop to direct sunlight and other weather conditions (strong wind, rain).
- In case of contamination of Dripstop, cleaning with water is recommended.
- When installing the roof, Dripstop on the roof profiles must be dry.
- Changes in quality resulting from contamination by microorganisms are not subject to complaints.
