Corrugated roof panels are commonly found in sheds, garages, greenhouses, warehouses and other auxiliary structures. These panels have gradually increased in popularity over time because of their cost effectiveness, ease of installation and ability in protecting against external agents. Property owners have many kinds of corrugated roofs to choose from, and it is important to assess individual cost factors and roofing needs before committing to a particular one.
Three common patterns dominate the corrugated roof panels market. The first and most popular is the basic round corrugated panels, consisting of a short curved wave pattern that allows a sheet to easily fit with each other during installation. The other is corrugated square panels, similar to the basic round style except that the wave pattern is square. These types of panels are usually used to build the roof decking. The third is alternately ridge panels, where flat valleys separating large and small alternating ridges. This construction provides durability while allowing the panel valleys that is easily mounted on the rafters.
Corrugated roof panels are commonly made of metals such as steel, aluminum, copper and zinc. Steel is the most popular and typically is either stainless or galvanized. Galvanized steel is generally stronger and cheaper, and stands up to harsh weather better than its Rust cousin. However, stainless steel is generally considered more aesthetically pleasing and does not require a zinc coating to protect against corrosion, which makes galvanized (zinc turns often unsightly color over time).
