metal roofs

Metal roofs are sometimes made of corrugated galvanized steel: a wrought iron–steel sheet was coated with zinc and then roll-formed into corrugated sheets. 

Another approach is to blend zinc, aluminum, and silicon-coated steel. These products are sold under various trade names like "Zincalume" or "Galvalume".

The surface may display the raw zinc finish, or it may be used as a base metal under factory-coated colors. Another metal roofing product comes in a rolled form of various widths of so-called standing seam metal. 

The material is "seamed" together using a special roof seaming machine that is run vertically up the panel to seal the joints and prevent water intrusion.

1. Corrosion

Though metal roofing materials are not coated to resist rust, it can still be inevitable. It can be caused by:

-The reaction between your fasteners and metal sheets or panel, bruising your coating.

-Other sides of the metal sheet or panels are not coated. 

-Edges are not sealed

-Humid and Salty Air 

Corrosion can be prevented by:

-Application of special paint for rust resistant 

-Properly coat edges and fastener holes

-Invest in higher grade metal roofing sheets or panels

2. Scratches and Scuffs

Metal panels or sheets can be bruised or punctured because of:

-Heavy falling objects (like tree branches)

-Strong hail storms and winds (Ice Damage)

Scratches and Scuffs can be prevented by:

-Proper coiled or recoiled metal during installation

-Avoid heavy traffic on metal roofs (during repair or installation) 

-Trim off tree branches
