If you’re in the market for a new roof, too few options will not be a problem. New technologies and innovations now make it possible to have just about any look you desire, no matter where you live.
When choosing roofing materials, consider the following questions:
- How heavy is this material?
- Does it require special framing?
- Does it come in a variety of colors and styles that complement your home?
- Does it meet the fire codes in your area?
- Are there any installation and maintenance issues?
- Does it perform well in your climate?
- What is the cost, life span, and warranty?
The answers to these questions, along with the following information, will help you determine the best choice for your home.

House Styles: Work with many architectural styles, especially traditional styles.
Cost and Life Span: From $70 to $120 a square and, if maintained properly, shingles will last 20
to 25 years. (In roofing terms, a square refers to 100 square feet of roof or a roll designed to cover 100 square feet of roof.)
Clay and Concrete Tiles

Wood Shingles and Shake
Pros: Wood shingles offer a rustic look and are a natural product usually made from cedar, redwood, or southern pine.

House Styles: Rustic aesthetic pairs well with bungalow, Cape Cod, cottage, Craftsman, and Tudor-style homes.
Cost and Life Span: Shingles — about $4.50 to $9 per square foot, installed. Shakes — around $6.50 to $11 per square foot, installed. In dry climates, a wood shingle or shake roof can last 60 years. In damp conditions, maybe 20 years.
Synthetic Roofing Products

A green roof is a layer of vegetation planted over a waterproofing system installed on top of a flat or slightly sloped roof. Green roofs are also known as vegetative or eco-roofs.
Pros: A living roof offers improved air quality, less pollution, better insulation (reducing heating and cooling costs), water conservation, and wildlife habitat.
Cons: Expensive to install. Reinforcing the roof of an existing home can necessitate expensive structural changes. Improper installation, inadequate drainage, or roots penetrating the protective membrane can cause leaks.
House Styles: Work with many different architectural styles.
Cost and Life Span: Depending on intensive, extensive, or semi-intensive, costs range from $10 to $50 per square foot. The average lifespan when properly maintained is 40+ years.
