Galvanized Metal Roofing is among the most preferred roofing materials for commercial and residential buildings, due to its considerable strength, resistance to rust and it’s cost effective. This roofing, with a layer of zinc, can endure extreme weather and hence cannot rust making it perfect for poles. Available in a variety of interior designs and colors, galvanized roofing has an increased factor of protecting against environmental damage and architectural beauty of the structure.
What is galvanized metal roofing?
Galvanized metal roofing is made from steel that has been coated with a layer of zinc to protect it from rust and corrosion. This coating enhances the steel’s durability, making it a long-lasting and weather-resistant option for roofing. The zinc layer acts as a barrier, preventing moisture and other elements from reaching the steel and causing damage.
Importance of galvanized metal roofing?
Corrosive damage is rarely seen due to the inclusion of the zinc coating which offered protective cover on top of the metal box, thereby increasing the durability of the roof.
- Longevity: the metallic roof that is galvanized coated metal sheets is very durable and can be over 50 years if well maintained.
- Affordability: galvanized metal is cheap as compared to other types of roofing materials, while giving good returns on investments.
- Maintenance: requires little attention the long-term considerations are less.
Galvanized metal roofing details:
Galvanized metal roofing, like all other metal roofs, is made of steel that has been zinc-coated to prevent corrosion. Zinc is employed in these roofing materials to create an exterior gel-like coating against any moisture detected in the air and other potential hazards that might degrade the metal over time. Galvanized roofs and other structures are available in panels or shingles, allowing for architectural design flexibility. Its surface is adequately reflective, making it energy efficient by lowering heat absorption and air conditioning costs in warm climates. The roof covering is also fireproof, providing an additional layer of protection to your home.
How to measure galvanized metal roofing?
One should accurately measure a galvanized metal roof by calculating roof area, slope and using the right tools for a correct estimation.
Steps to measure:
- Determine roof area: determine the length and the width of each section of the roof. The area or square footage can be approximated by multiplying length and width.
- Calculate roof slope: track the rise and run of the roof. The slope ratio will assist in determining the total amount of roof area.
- Account for overhangs: measure the additional surfaces available due to overhangs or additional roofs.
- Convert to squares: this is applying a standard system of measurement among roofing practitioners. One roofing square is equivalent to 100 square feet.
Tools to measure:
- Measuring tape
- Ladder
- Roof slope calculator or app
- Safety harness

Is a galvanized metal roofing cheaper than asphalt shingles?
Galvanized metal roofing is usually more expensive than asphalt shingles. Cost-wise, asphalt shingles cost very low which is between $3 and $5 per square foot, whereas galvanized metal sheets usually go for $6 to $10 per square foot. The high initial cost of having galvanized metal roofs is due to the processes required as well as the quality of inputs used to manufacture them. Nonetheless, their outstanding strength and low upkeep will turn out to be a reasonable alternative over a period of time.
Are galvanized metal roofing better than asphalt shingles?
Yes, galvanized metal roofs generally outperform asphalt shingles in several key areas:
1. Durability:
While asphalt shingles only last about for 20-30 years, galvanized metal roofs can last for up to 60 years or even more because they do not rust and they are not easily corroded. Zinc on galvanized metal is the greatest device that fights adverse weathered conditions and corrosion.
2. Energy efficiency:
There are many available forms of roofing materials to choose, but installing galvanized metal roofing systems provides numerous heating and cost saving benefits within structures. In particular, darker asphalt shingles, heat absorption is so high that cooling costs in warm areas are more than necessary.
3. Maintenance:
There is less trouble with maintenance work with due regard to galvanized metal roofs as opposed to asphalt shingles. Because of their lifetime, they will be less prone to factoring issues such as cracking, curling or granule loss (in this case) which increases the life span of the metal ones.
4. Weather resistance:
They also withstand severe weather conditions, heavy rains, and snow and high-speed winds better than any other roofing materials. Compared to asphalt shingles, they are also better off when faced with hail storm damage.
