Metal roofs, crafted from steel, aluminum, or copper, are fire resistant – lightweight structures offering durability, longevity and low maintenance. Metal roofing is a common method for industrial or commercial buildings, however, climatic conditions have a great impact in the lifecycle of metal sheets, causing corrosion and damages that lead eventually to water leaks. ALCHIMICA’s waterproofing system provides economical and durable refurbishment and protection for metal roofs in inclined and vertical substrates.
