How To Choose A Metal Roofing System

Metal roofing has become a popular choice for both re-roofing and new construction. This article will help homeowners who are considering this construction material find answers to frequently asked questions. Some homeowner’s insurance companies offer a discount for those with metal roofs. Also, metal roofs can reduce energy costs by reflecting sunlight and releasing absorbed heat.


Depending on the style and thickness of metal used, costs can vary. A metal roof will also be influenced by the installation method; a snap lock panel, for example, will be less expensive than a standing seam option. In the long run, however, metal roofing is often more cost effective than shingles or other types of traditional roofs. This is because it has a lifespan of 40 to 70 years or more and comes with a warranty against leaks and corrosion.

In addition, the material resists mold, mildew and rot. And, unlike shingles, it is impervious to abrasion and is not easily damaged by hail or fallen debris. Although metal roofs are not insulated by themselves, insulation can be added, allowing homeowners to reduce their energy bills and stay cozy and comfortable. Lastly, many varieties of metal roofs contain a high percentage of recycled material, making them an eco-friendly choice. This is especially important for those who are concerned with sustainability and the environment.


Metal roofs routinely last 2-4 times longer than asphalt shingles, meaning homeowners have to replace their roof less often, significantly cutting down on future roofing costs. Additionally, since a metal roof reflects the sun’s heat instead of absorbing it, it helps keep homes cooler during summer, which saves on energy bills. Unlike shingle roofs, which are prone to mildew and fungus growth (which can cut their lifespan by up to half), a metal roof is impervious to these fungal attacks. It also protects homes from raccoons, rodents, and other wild animals that may be able to penetrate a wood or asphalt roof to get into the attic.

Bare steel is vulnerable to rust, but new coatings like galvalume and galvanized metal have greatly increased its ability to resist corrosion. These coatings are available in a variety of colors, so you can find the one that matches your home. In addition, a properly installed metal roof is fire resistant and can help reduce insurance premiums.


Metal roofing is becoming more and more popular, getting close to dethroning asphalt shingles as the top choice for new roofs. Its durability and attractive curb appeal make it a good option for homeowners. Metal roofs come in a variety of colors, designs, and styles to match any home. They are also more energy-efficient than other roofing materials. Some have reflective pigments that reduce heat retention. They can also be designed to easily shed snow, reducing air conditioning costs in the summer.

Many types of metal roofs are available, including corrugated tin, standing seam construction, and panels that simulate the look of clay tiles, slate, or wood shingles. They can be through-fastened or with concealed clips. Most of the structural systems are built to withstand strong winds, while non-structural products require a solid substrate such as plywood or oriented strand board beneath them. Most metal roofing is made from recycled material, so it’s an eco-friendly choice for those with sustainability as a priority. It is also fire resistant, making it safe in areas prone to wildfires and lightning strikes.


Metal roofs are durable and long-lasting, but they need to be properly maintained to maximize their lifespan. Annual maintenance inspections help prevent major problems such as leaks, dents, and corrosion. They also ensure that your metal roof is aesthetically pleasing. Depending on the type of metal roof you have, your maintenance needs may vary. For example, screw down metal roofs require different maintenance than standing seam metal roofs. Screw down metal roofs have exposed fasteners, which can become loose or crooked over time. Screws should be sealed periodically, especially in hot climates.

Other types of maintenance include removing snow and ice from the roof, cleaning the panels, and trimming nearby branches. A roofing contractor can also clean gutters and drains, which often get clogged with leaves, sticks, and other debris. Clogged gutters can rust the metal roof and cause water to seep into the home. A roofer can also install gutter guards to prevent future debris buildup.

Last Word

The soothing sound of rain on a metal roof has inspired many homeowners to choose it for new construction and replacement projects. However, there are important considerations when choosing this material. For example, a steel roof must be galvanized to protect it from corrosion. A popular option is to use Galvalume, which combines bare steel with an aluminum and zinc alloy.
