3. Cost-Effectiveness Although the initial cost of metal roofing can be higher than traditional shingles, its longevity and low maintenance requirements often lead to significant savings over the lifespan of the roof. A well-maintained metal roof can last 40 years or more, making it a wise long-term investment.

They are typically made of metal and can be placed directly into the soil around the plant. Cages are particularly useful for indeterminate tomato varieties, which continue to grow throughout the season.
