A properly installed metal roof can last 40 to 70 years or more, depending on the material type, installation quality, maintenance, and environmental exposure. In wet climates like the Puget Sound, durability and corrosion resistance play an especially important role in long term performance.
Homeowners comparing roofing options often focus on asphalt shingles first. However, metal roofing systems are increasingly considered for their longevity and weather resistance.
While it isn’t something that comes to mind for most people, metal roofs are becoming more popular, and have a lot of positive qualities. The right materials and proper care can make a major difference. That’s why early in the process you should consider scheduling a roof installation so the job is done right from the start.

Residential Metal Roofing
While metal roofing is less common in some neighborhoods than asphalt shingles, it has grown in popularity due to its durability and lifespan.
Metal roofing panels are designed to shed water efficiently and resist cracking, splitting, or granule loss. In regions that experience heavy rain and wind exposure, these characteristics can be beneficial.
Homeowners in Tacoma, University Place, and throughout Pierce County often consider metal roofing when evaluating long term return on investment and reduced replacement frequency.
What Affects Metal Roof Lifespan?
Several factors influence how long a metal roof lasts:
Material Type
Steel, aluminum, and specialty coated metals may have different corrosion resistance properties.
Protective Coatings
Factory applied finishes and coatings help resist rust and UV exposure.
Installation Quality
Improper fastening, flashing details, or underlayment selection can reduce lifespan.
Maintenance
Periodic inspections help identify loose fasteners, sealant degradation, or debris buildup.
While some metal roofing systems carry long term manufacturer warranties, actual performance depends heavily on installation quality and ongoing care.
The Advantages of a Metal Roof
Longevity is one of the primary advantages of metal roofing. Compared to many asphalt systems, metal roofs often have longer projected service lives when properly maintained.
Additional potential benefits may include:
-
Compatibility with solar panel systems
-
Reflective surface options that may reduce heat absorption
-
Recyclable material components
-
Resistance to cracking and splitting
Metal roofing may involve higher upfront cost but can reduce replacement frequency over time.
When Is Replacement the Better Option?
Even durable roofing materials eventually require replacement. Signs that a metal roof may need evaluation include:
-
Persistent leaks
-
Visible corrosion or rust
-
Loose or missing fasteners
-
Panel distortion or denting
-
Improper installation details
