Metal Roofing

Steel, aluminum, copper, and zinc are the primary metals used in roofing. Offering great durability and low maintenance, metal roofs can withstand high winds, blowing embers, and heavy loads better than most other types of roofing.

Steel Roofs

A steel roof (also known as a tin roof) is sold in panels that interlock; these panels can be textured to simulate shingles or may be a simple ribbed pattern. As you would expect, heavier panels provide greater rigidity and thus resistance to buckling under snow and wind loads.

A natural enemy of metal roofs is rust. To prevent rusting, the roof is either painted or it is galvanizing with zinc. Painting blocks the moisture from reaching the metal while zinc actively fights rust by "healing over" small scratches. Premium metal roofs use a combination of galvanizing and paint to take advantage of both approaches and provide long lasting protection. Because the zinc layer thins with time, the thicker the zinc coat, the longer the protection.

Aluminum Roofs

Aluminum is the low cost, low weight alternative to a steel roof. Aluminum is corrosion resistant and can be painted to meet the color requirements of your home design.

Copper Roofs

Unless coated, cooper roofs begin shiny like a new penny but oxidize into the green color often seen on buildings built before the early 1900's. Copper roofs, strong and resistant to corrosion, last for hundreds of years. However, both the material cost and the installation is very expensive.

Zinc Roofs

Zinc roofs are similar to copper roofs in most ways except that they oxidize into a bluish-white.
