What are the pros and cons of composition shingle roofs versus metal roofs?
Both roof types come in many styles and colors. Metal is more fire resistant than composition or wood roofing and can be applied more quickly. Metal roofs can usually be installed right over the old roof. Some are guaranteed for 50 years or more. Metal roofs are more expensive and are easily damaged if walked on incorrectly. Composition shingles come in several different grades, which are judged by the guaranteed lifetime, usually 20, 30, or 40 years. The longer-lasting shingles are thicker and their shaped appearance makes a more attractive roof.
