Slate is a dense, tough, durable rock which is mined from quarries generally from the eastern United States. Slate, which is practically non-absorbent, was formed over 500 million years ago. Roofing slate comes in many different sizes, thickness, and colors. The basic colors of roofing slate are black, gray, green, purple, and red. Exposure to weather causes all slate to change slightly in color. The degree of color change varies with different slates. Those slates which exhibit minimal color change are called "unfading" slates. Those slates which exhibit a more obvious color change are known as "semi-weathering" or "weathering" slates. Roofing slate thickness are a standard 3/16 of an inch thick and can be up to 2 inches thick.The longevity of a slate roof can be any where from 50 years to 400 years depending on the quality of slate used.
A cedar shake roof gives your home a more rustic look. Cedar shakes are a natural roofing material harvested from cedar trees. Although shakes are made from wood, they generally have a longer life expectancy than the standard asphalt shingle, as much as 30 years with proper care and maintenance. Standard cedar shingles have natural oil in them that prevent rot and decay, however, you can purchase cedar shakes that have been treated, offering added protection and life.
Asphalt roofing shingles are cost-effective and versatile, which may be why they cover more than 75% of the roofing market. Asphalt shingles are fairly inexpensive, install easily, and are suitable for roof pitches from 4-in-12 to vertical, and are available across a wide range of quality, cost, and style. Easy to cut, fit, and fasten, asphalt shingles are compatible with many different kinds of flashing and edging products, and don't require specialized accessories for roof edges, wall terminations, and chimney or vent flashings. Asphalt roofing shingles are available in various life span options from 15 to over 40 years. The shingle manufactures will typically sell shingles by weight per bundle. A general rule of thumb is the heavier the bundle, the thicker the shingle, the longer the warranty. Some criticism exists among builders and homeowners as to the true life expectancy of a shingle. It should be mentioned that a 20 year shingle would expect that the roofing shingles would last 20 years under ideal conditions, but unusual temperature, extremes wind, and excessive rain, may shorten the life expectancy of your roofing system.
Metal roofing is generally more expensive, your savings over the course of its life are something to consider.

This is particularity appealing and advantages when it comes to the resale of your home if one day you decide to do so. With a color palette of options, styles, and quality, a new metal roof on your home will look great from the day you put it on, well into the days of your retirement.
