Over the centuries, virtually everything imaginable has been used to make a roof. Banana leaves and straw have given way to composition shingles and metal as some of the material in use today.
The roof is simply defined as the top of a structure. This might range from a mailbox enclosure to a stadium, but by far the most common roof as always enclosed a dwelling. Over the years there have been many roofing materials used and they have ranged from banana leaves and straw thatch to the modern composition shingles and various types of metals. The main purpose of the roof has always been to keep rain and snow out of the dwelling and to insulate it from cold and heat.
It is estimated that the average roof needs to be replaced every 10 years, but this average is made up of some wide variations. The less often replacement takes place, the better for the homeowner as well as the environment as discarded roofing material is a major source of waste. Today, one of the most popular types of roofing material is composition shingles. They are extremely versatile and easy to install. In many cases, they can be nailed right over existing roofs. There major downside is that they can tear away easily in high winds and do not have the same dimensional look as tile or shake roofs.
Wood shake roofing material is popular in many upper income homes because of its natural look. Wood shake seethes with character, and provides a great energy benefit that often offsets its cost. It is subject to rot and invasion by insects and does not have the fire retardant qualities of other roofing material. Also, there is really no use for replaced or discarded wood shake roofing material.
Clay roofing tile is very common in homes that are seeking a Southwestern look or Mediterranean look. They are long lasting and require very little maintenance. Ceramic tiles have been used as roofing material in certain parts of the world for centuries. They are heavy and fragile, as well as a bit expensive when compared to other materials. Other choices include concrete tile, slate, and the increasingly popular metal roofing materials. Metal enjoyed a lot of popularity in the past and is making a comeback. Standing seam steel roofing is an example of energy efficient use of metal roofing material.
There is a wide variety of roofing materials available. Your choice can be based on a number of factors ranging from durability to personal taste. Neighborhood standards and climate are other factors that can influence the choice. Your roof is something you tend to take for granted until it fails to do its primary function of keeping you warm and dry. It is much better to understand the maintenance needs and lifespan of your roofing material and make sure you always have a 'roof over your head."
