Metal Roofs: Pros, Cons, and Installation

by Team CallAPro

Metal roofs are becoming increasingly popular among homeowners due to their durability, longevity, and energy efficiency. However, before deciding on a metal roof for your home, it's important to consider both the pros and cons, as well as the cost and installation process.

Pros of Metal Roofs

  • Durability: Metal roofs are incredibly durable and can last up to 50 years or more with proper maintenance.
  • Energy Efficient: Metal roofs can reflect the sun's rays and help to keep your home cool in the summer, resulting in lower energy bills.
  • Low Maintenance: Metal roofs require very little maintenance, and are resistant to rot, insect damage, and mildew.
  • Fire Resistant: Metal roofs are fire-resistant, which can provide peace of mind in areas prone to wildfires or lightning strikes.
  • Environmentally Friendly: Metal roofs are often made from recycled materials and can be recycled at the end of their lifespan.

Cons of Metal Roofs

  • Cost: Metal roofs can be more expensive than traditional asphalt shingle roofs, but they also last longer and can save money in the long run.
  • Noise: Some homeowners find that metal roofs can be noisy during rain or hail storms, but insulation and other noise-reducing materials can be added during installation to mitigate this issue.
  • Denting: Metal roofs can be prone to denting from falling branches or hail, but many manufacturers offer warranties that cover denting.
  • Slippery: Metal roofs can be slippery, which can be a safety hazard during installation and maintenance.

Cost of Metal Roofs

The cost of a metal roof can vary depending on the type of metal used, the quality of the installation, and the size and complexity of the roof. On average, the cost per square foot for a metal roof installation can range from $7 to $12. However, this cost can increase if additional materials or installation techniques are required.

Installation Process

The installation process for a metal roof typically involves several steps:

  1. Removal of the old roof: The existing roofing materials are removed to ensure a clean, smooth surface for the new metal roof.
  2. Installation of underlayment: A layer of underlayment is added to provide an extra layer of protection against water infiltration.
  3. Installation of metal panels: The metal panels are installed according to the manufacturer's specifications, often with screws or clips that allow for expansion and contraction with temperature changes.
  4. Installation of flashing: Flashing is installed around any roof penetrations or areas where the metal roof meets other materials, such as chimneys or walls, to ensure a watertight seal.
  5. Cleanup and inspection: Once the installation is complete, the area is cleaned up and inspected for any issues or problems.
