What are Corrugated Metal Roofs?
A corrugated metal roof is a type of roofing that uses metal sheets, which are shaped to have panels and ridges. These curves and patterns give the sheet strong structural integrity and sturdiness. Therefore, they have higher strength-to-weight ratios making the roofs weather resistant.
Corrugated Metal Roofs vs. Metal Shingles
The main difference between corrugated metal roofing and metal shingles is the size of the metal. When installing a corrugated metal roof, the entire sheet of paneled metals is screwed on the roof. For metal shingles or tiles, individual pieces are attached to the roof.
Corrugated metal roofs are sturdy and strong and used to cover longer roofs. They are mainly used for agricultural, industrial, and commercial purposes, but can also be used for some types of residential home roofing. On the other hand, metal shingles and tiles are specifically designed for residential roofs and come in several styles and designs.
Benefits of Corrugated Metal Roof Installation
While the initial material and installation cost of a corrugated metal roof is higher than asphalt shingles or other standard roofing material, the longevity is far superior. Corrugated roofs last two to three times longer than a typical non-metal roof – their lifespan is 30 to 45 years.
Across the country, homeowners who invest in corrugated metal roofing get an average ROI of 85.9%. Corrugated metal roofing can also lower your insurance rates because of its fire resistance, especially in states like Texas and California that are vulnerable to wildfires. These roods are also extremely energy-efficient and durable.
Corrugated Metal Roofing Panels
Corrugated metal roofs are gaining popularity for homes because of their low cost, durability, and unique look. Simple laying procedures make corrugated roofing a quick and easy do-it-yourself project, too.
Corrugated metal roofing structures are more rigid than flat roofing structures, providing more dimensional stability and structural integrity. For instance, corrugated roofing can make a lightweight metal like aluminum sturdy enough to withstand the elements. Corrugated metal roofing is most commonly available in aluminum, stainless steel roofing, and copper roofs. These three metals differ in appearance, cost, and durability.
We always suggest finding a local roofer to help you with a new roof installation to be sure you are getting it installed properly the first time around.
Corrugated Aluminum Roof
Corrugated Steel Metal Roofs
Corrugated steel metal roofing sheets come with a built-in, natural gray finish. Though some homeowners like the industrial look, changing the color of the sheets with paint can be challenging. Corrugated steel roofing is more expensive than aluminum roofing.
Corrugated Copper Roofs
Corrugated copper roofing is easy to install and naturally resistant to rust. In fact, it will patina naturally over time. It is the most expensive type of corrugated roofing. Resistant to cracking, shrinking and eroding, corrugated roofing systems can withstand extreme weather conditions including heavy snow, hail, and wildfires.
Metal Roof Maintenance
Most corrugated products are made from galvanized steel. Galvanization is the process of applying a thin layer of zinc on the surface of the corrugated metal to protect it from rust (oxidization) and corrosion. At some point, long term exposure to the elements will deteriorate the protective finish and you will need to re coat your metal roof. A simple polymer re-coating will restore your corrugated metal roof to like-new conditions. To wash, use simple soap and water–a hose or a pressure washer can be used, but avoid abrasive tools like wire brushes or steel wool that can scratch your roof.
