Metal roof maintenance
Color Steel Roof Repair System
Assess corrosion, seams, fasteners, movement, the existing coating and weather exposure before selecting a compatible repair and protective coating sequence.
Metal roof diagnosis
Repair the defect before applying a protective coating.
A coating cannot restore loose, perforated or structurally unsound steel. The roof should first be surveyed so failed sheets, fasteners, seams, corrosion and drainage problems can be repaired with compatible methods.
This page covers a coating-based repair route for color steel roofing. It does not describe spray-foam insulation.
Compatible repair sequence
Build the repair around the verified roof condition.
- 01
Inspect and make safe
Identify unsound sheets, failed fasteners, open seams, corrosion, standing water and areas requiring replacement or structural repair.
- 02
Clean and prepare
Remove contamination, loose rust and poorly bonded coating to the preparation level required by the selected material.
- 03
Treat details
Repair fasteners, seams, laps, penetrations and local defects with a compatible detail method.
- 04
Prime and protect
Apply the confirmed primer and protective layers within the documented weather, film-build and recoat limits.
