The biggest problem with metal roofs is often related to installation issues, which can lead to leaks, corrosion, and reduced performance. Inadequate fastening, incorrect overlapping, or improper sealing of seams, penetrations, and flashing can result in water infiltration. Additionally, metal roofs can be prone to noise during heavy rain or hail, and expansion and contraction due to temperature fluctuations. Choosing a reputable contractor and ensuring proper installation and maintenance can mitigate these potential problems.

Initially, installing asphalt shingles is typically cheaper than a metal roof due to lower material and labor costs. However, metal roofs have a longer lifespan, often lasting 40-70 years, compared to asphalt shingles, which last 15-30 years. Metal roofs also require less maintenance and can provide energy savings due to their reflective properties. When considering long-term costs, durability, and energy efficiency, a metal roof may be a more cost-effective option over time.
