One of the most popular choices among householders and builders nowadays is metal roofing. The choice of material when deciding on roofing is mainly due to their reliability, energy efficiency, and aesthetic appeal as a prime contender in construction today. Let's consider the world of metal roofing and see why it is the perfect choice for you.
What Is a Metal Roof?
A metal roof refers to roofing constructed from pieces of metal or tiles having features of very high resistance, impermeability, and longevity. The popular types of such materials comprise steel, aluminum, copper, and alloys of zinc.
Advantages of Metal Roofs
Longevity and Durability
The most impressive advantage of metal roofs is that they have a remarkable life expectancy. While conventional asphalt shingles might last 12-20 years, metal roofs may survive for 40-70 years, depending on the material. They require less frequent replacement and are cost-effective in the long term..
Energy Efficiency
Metal roofs reflect solar radiant heat, which can reduce cooling costs by 10-25%. Reflective coatings on some metal roofing materials make your home more comfortable during the hot seasons.
Low Maintenance
While shingle roofs are less durable, and metal roofs are also longer-lasting, regular check-ups are still required for them to ensure they are functioning.
Environmental Benefits
Metal rooves are 100 percent recyclable and can be made from other recyclable materials. Contrarily, Asphalt shingles are based on petroleum, and they incorporate chemicals in their composition, making recycling toxic. So, most shingles are not recycled, and 20 billion pounds of them landfills annually, taking hundreds of years to decompose, which is an environmental hazard.
Types of Metal Roofing Materials
Steel
Steel is widely used because it performs well and is strong. Galvanizing adds a coating layer of zinc, while Galvalume covers its surface with a layer of a zinc-aluminum alloy.
Aluminum
Aluminum is non-heavily built and thus corrodes little. Hence, aluminum is also a material recommended for coastal environments. It has flexible design possibilities.
Copper
Copper roofs have a peculiar appearance and may last more than a century. It acquires a protective patina with time that contributes to the attractiveness and longevity of copper.
Zinc
Zinc roofs offer good durability, acquiring a self-healing protective patina that can cover scratches.
Installation Process
Preparation
Before the installation process, it is imperative to measure up the roof structure for adequacy in holding up the metal roofing system. The proper measurement and choice of material are critical at this point.
Underlayment
Underlayment installation offers an extra layer that safeguards against moisture. It's an important step because leaks can be avoided while also lengthening the lifespan of the roof.
Panel Installation
Metal panels are installed from the eaves up, and it is ensured that they are aligned properly and fastened securely. This step also ensures that there is no panel misalignment or water infiltration.
Sealing and Flashing
Proper sealing and flashing around roof penetrations, such as chimneys and vents, are critical to preventing leaks and ensuring the integrity of the roof.
Maintenance Tips
Regular Inspections
While metal roofs require fewer maintenance efforts than other materials, there is still a need to check on them regularly. Check for signs of damage, corrosion, or loose fasteners to address potential issues quickly.
Cleaning
Keep the roof free from debris, like leaves and branches, so moisture retention and potential damage will not occur. Gentle washing with water and mild detergent may be done to maintain its appearance.
Addressing Repairs
If you find dents, scratches, etc., they will require to be addressed and may need touch-up of paint for minor scratches but turn to the professional repair for more intense marks.
Cost Considerations
The initial cost may be a little higher, such as traditional materials used when building a house, with durability, low maintenance requirements, and energy efficiency. This is a future investment though saving money in the future with a metal roof installed in your home.
Aesthetic Options
Metal rooves come in many different styles, colors, and finishes. They can give a home a desired look, ranging from traditional standing seam profiles to metal shingles that resemble other materials.
Potential Drawbacks
Noise
Without adequate insulation, metal roofs are also noisier during rain or hail storms compared to asphalt shingle counterparts. Modern installation techniques and appropriate insulation can significantly mitigate this issue.
Expansion and Contraction
With a temperature change, the expansion and contraction can cause fasteners to lose hold over time. This aspect necessitates proper installation and maintenance to prevent this effect.
Environmental Impact
The selection of metal roofing promotes sustainability in the environment. These are recycled and are energy efficient to lower your home's overall carbon footprint. The choice to have a metal roof has benefits in various aspects, ranging from long-time durability to energy efficiency to aesthetic variability. Indeed, the up-front investment in such roofs is steeper, but the benefits thereafter make them a viable alternative for anyone.
