Rooftop Waterproofing — Why “Steel”? The Difference from Conventional Methods

We summarize the limits of coating and sheet waterproofing, and why steel waterproofing based on high corrosion-resistant steel leads in durability and maintenance.

Rooftop Waterproofing — Why “Steel”? The Difference from Conventional Methods

Rooftop waterproofing is a key process that determines a building's lifespan. The widely used coating and sheet waterproofing are easy to apply, but they tend to crack or lift under UV rays, thermal shock, and external impact.

Strengths of steel waterproofing

  • Durability — retains shape and performance over the long term with a high corrosion-resistant alloy-coated steel sheet
  • Corrosion resistance — 5–10 times higher than ordinary galvanized steel
  • Climate resilience — strong against external impact and rapid climate change
  • Maintenance — reduces the burden of repeated re-application

The value of preservation

Owellsteel values the worth of preservation. The ROOFGUARD steel waterproofing system aims to protect your rooftop for the long term with a single, properly executed installation.
