The Average Metal Roof Lifespan
The question, “how long does a metal roof last?” does not have a simple answer. Your roof’s lifespan depends on the installation method and type of metal. The average metal roof lifespan is around 50 to 70 years, though this range fluctuates.
The average times for the different roofing system installation types include:
- Standing seam: Standing seam roofs last 30 to 50 years with a 30-year warranty period. The installation method involves locking together panels with mechanical seams.
- Panel: Panel roofs last 20 to 30 years and require more maintenance. During installation, contractors screw down each board with fasteners.
Metal Roof Lifespan for Each Material
The type of metal you choose can extend your roof’s lifespan. Certain materials last better in different climates than others. The main types of metal roofs include:
- Steel: Steel roofs come in many designs and colors that mimic natural materials like clay, shingle, or slate. With a rust-resistant coating, this material doesn’t require maintenance and lasts an average of 40 years.
- Copper: Green copper roofs offer the most durable option with natural anti-rot components while remaining lightweight. The average copper roof lasts around 50 to 100 years.
- Aluminum: Aluminum roofing systems are also lightweight and combat corrosion, though they do not always include a waterproof coating. Since aluminum reflects sunlight, this roof can improve your home’s energy efficiency. Expect aluminum roofs to last around 50 years.
- Tin: Tin roofs also last an average of 50 years, though many homeowners complain that they are too loud in the rain. You can add extra underlayment materials to reduce this sound.
- Zinc: Zinc roofs are sustainable and last just as long as copper, at around 60 to 100 years. The zinc material requires little maintenance and can handle scratches without leading to expensive leaks.
Factors That Determine the Lifespan of a Metal Roof
The lifespan of a metal roof also varies based on a few factors besides materials. Some of the average estimates above depict ranges as large as 50 years because the unique environment around your home determines how long any roof lasts. The main factors include:
- Weather: Heavy snowfall, severe winds, and extreme temperatures affect how long your roof lasts. Mild climates with average temperatures and rainfall allow roofs to reach the longer end of the expected lifespan. Certain materials do best in cold versus hot climates and dry versus wet areas, so you should pick something best suited for your location.
- Maintenance: Many roofs require regular maintenance that prevents minor issues from snowballing into major complications. You might need to remove debris, clear your gutters, and check for small scratches that could develop cracks or leaks.
- Proper installation: The installation of your roof directly impacts how well it performs. Poor installation might leave you with leaks, exposed underlayment, damaged finishes, and many problems down the line. Stick with professionals, like our team from Aspect Roofing Company.
- Color: Lighter colors reflect sunlight, and dark colors absorb it. The color of your roof affects how hot the materials get and how long they last. Avoid overheating roofs by picking a light color or adding an acrylic elastomeric roof coating.
- Sun exposure: Ultra-violet (UV) rays from the sun damage the coatings on your metal roof faster, so if your home sits in direct sunlight in a high-UV area (desert climate), your roof might not last as long. Unfortunately, shade isn’t always the answer. Zero direct sunlight causes moss to grow and creates additional complications.
Why Do Metal Roofs Last So Long?
Metal roofs last long because of the material’s natural strength and ability to deter pests. Unlike traditional materials, metal offers durability against the strongest weather patterns and doesn’t allow pests to nest. Modern advancements improve metal roofing systems, ensuring that each fastening component has top-notch quality standards.
