Widespread Rust and Corrosion
Metal Roof Problems & Solutions
Widespread Rust – Rust forms and spreads, causing corrosion to the entire metal roof surface.
Un-primed Painted Rust – Rust breaks through chipped and cracked paints and coatings that were improperly applied.
Chemical-Caused Rust – Factory chemicals previously exhausted onto roof caused rust to form to the surrounding area.
Rust From Underside – Leaking fasteners caused insulation saturation that rusted through metal roof panels from the underside.
Valley Gutter Rust – Clogged downspouts and poor roof water drainage caused valley gutters to hold water too long and rust more quickly and prematurely.
Fastener Rust – Fasteners began to rust and spread rust to the metal roof surface.
Fixture Rust – Roof pipes, vents, and stacks dripped and spread rust onto roof, causing roof to rust.
Downspouts from a higher roof section slow and steadily drain onto a lower roof causing premature rust along these panels.
