When it is time to replace your existing roof, you may shy away from metal as an option because of price concerns or false perception of the aesthetic value. The modern metal roof is no less attractive than any other material and the higher upfront cost translates into a sturdy roof that can withstand the elements.
No matter the climate you live in, having a solid roof that can withstand different weather events is critical. Two of the major threats to the durability of your roof are high winds and moisture. Metal roofs are better able to withstand high winds that can occur during severe weather. Furthermore, unlike materials such as wood or asphalt shingles, which can become less durable due to moisture, metal does a better job at resisting moisture damage.
Depending on the metal you choose, you can find a good compromise between affordability and rust-resistance. Due to fewer concerns regarding water damage, you also reduce moisture-related concerns by choosing metal. Some common concerns that are caused or exacerbated by moisture damage are rotting, leaks and pests.
Warding Off Ice And Snow
If you live in a climate that has harsh winters, a metal roof can mean the difference between your house withstanding large amounts of frozen precipitation and disaster. Just a few inches of snow accumulating on the roof can place a significant burden on any structure, particularly homes. Metal provides a unique combination of naturally defrosting your roof, while being a lightweight material to reduce added weight. Allowing your roof to do the work can reduce the inconvenience and safety risk associated with removing the snow yourself.
Many locations that experience harsh winters may not regularly rise above freezing temperatures during the daylight hours, which limits the melting of ice and snow. Additionally, the small amount of melting that occurs during the day only re-freezing at night. A metal roof reflects sunlight to help melt the snow and ice off your roof, even if the temperatures are below freezing. Since metal stays warmer longer, this can minimize the amount of frozen precipitation that initially sticks to your roof. If you choose a dark coating for your roof, this can increase retention of heat and help with melting.
The reflective property of metal also makes metal roofs ideal for energy efficiency during the warmer months. When the weather is hot, more of the sun's rays are reflected off your roof, instead of being absorbed by the roofing material and increasing your home's temperature. If you live in an area that experiences significant heat waves, considerable savings on your monthly cooling bill is worth the initial investment of a metal roof. If you choose metal primarily for energy savings, opt for a roof that is light in color.
Safety In Severe Weather
Lightning is a common threat to homes, especially if you live in an area that frequently experiences severe thunderstorms without rain. Installing a metal roof seems counterproductive, due to the misconception that metal attracts lightning. Metal does not attract lightning, but it conducts electricity better than other materials.
When a metal roof is installed, the roof is grounded to make sure any lightning that happen to strike your roof passes safely toward the ground and not into the structure of your home. The combination of grounding and metal also reduces the likelihood of fires that occur from lightning strikes to the roof. Some roofing materials that are not as fire-resistant as metal can either catch fire quickly or smolder for hours before you are aware your roof is on fire.
The outdated image of a shiny, metal roof can be off-putting. Before canning the idea of a metal roof, check out sites like http://www.palmerroofing.net and seriously consider the safety and efficiency advantages in comparison to the upfront costs.
