Alchimica’s Exposed Metal Roof System is designed to deliver seamless, long-lasting waterproofing protection for both new and existing metal roof structures.

Metal roofs, while durable, are often prone to thermal movement, corrosion and leakage at joints and fixings.

Our system, based on advanced HYPERDESMO® liquid membrane technology, creates a fully adhered, elastic waterproof barrier that accommodates movement while protecting against water ingress and weathering.

Key features include:

• Excellent adhesion to galvanised steel, aluminium and other metal surfaces.
• UV and weather resistance for long-term durability in exposed environments.
• Highly elastic, accommodating structural movement and temperature changes.
• Corrosion-resistant formulation to extend the life of the roof.
• Ideal for both pitched and curved metal roofs, including industrial and commercial units.

Quick to apply and easy to detail around fixings and seams, Alchimica’s system offers a cost-effective alternative to replacement, extending the service life of metal roofs while reducing maintenance demands.
