A roof and its associated flashings, gutters, and downspouts function as a system to shed water. Flashings are the weakest point in any roof. Given the permanence of slate, it would not be prudent to use anything but the most durable of metals and the best workmanship for installing flashings. Copper is one of the best flashing materials and is often associated with historic slate roofs. Copper is extremely durable, easily worked and soldered, and requires little maintenance.
Copper has many applications in a roof system: flashing, downspouts, gutters and architectural detailing. Copper has many advantages, including:
- Aesthetic appeal. As copper ages it develops a natural protective coating of a blue-green patina that enhances the architectural style of the home.
- Longevity. When properly maintained copper can last approximately 70 years, or longer. The metal is highly resistant to fire, hail, and mildew.
- Weight. Copper is a lightweight, malleable material that can be used in many applications.
- Durability and low maintenance. Copper is resistant to corrosion and does not rust or pit like ordinary metals.
- Environmentally friendly. Copper is not toxic to humans or animals. It is considered a sustainable building material that can be recycled and/or re-purposed.
Copper also has disadvantages, including:
- Noise. A rainstorm sounds loud under a copper roof, no matter where you are in the home. The metal does not buffer noise as well as softer materials, like asphalt or wood.
- Investment. Installing copper is an investment in your home, and will require a larger financial commitment than other alternatives.
