G.I. Sheet Waterproofing Solution

Workers waterproofing a G.I. sheet industrial roof with solar panels

G.I. sheet roofs expand and contract with temperature, which slowly opens the fixing points and laps. We seal those points with flexible material and finish the roof with an elastomeric coating that moves with the sheet.

Common Problems We See

  • Leakage along screw lines after a few seasons
  • Open laps between sheets
  • Water entry at solar panel mounting points
  • Rust starting at cut edges and fixings

Our Solution

  • Surface cleaning and rust removal at fixing points
  • Flexible sealing of screws, laps and penetrations
  • Reinforcement over critical joints
  • Elastomeric coating over the treated roof

FAQ

G.I. Sheet Waterproofing — Questions

Can you work on roofs with solar panels installed?

Yes. We regularly treat industrial sheet roofs that already have solar panels, working carefully around the mounting structure.

Will the coating peel off the sheet?

Not when the surface is cleaned and primed correctly, which is part of our standard sequence.
