Today’s roofing materials are quite a bit different from roofing materials used in the past. Roofs made from wood or different types of grass are still found in some areas, but not very many. Wood tends to rot quickly and grass and thatch do not offer much protection from the elements. Roofing material such as shingles and tar paper can also still be found, but even that is being given up for more permanent roofing materials that do not need to be replaced at all or at least as often.
Mobile homes today are receiving a rubberized roof coating that helps to seal the roof as the aluminum roofing being to leak over time. Stick built homes are generally roofed with tar paper and shingles that over lap each other to keep the roof leak free. Custom built homes have a variety of roofing materials used on them from glass to steel to concrete. Building codes have also changed several times over the years, making more reliable roofing a necessity for newer homes.
Some of the more modern roofing materials include tile, slate, engineered plastic or rubber, and metal roofing. The other options still are available in wooden shingles or asphalt shingles as well. Tile and slate is expensive and very heavy although looks very attractive on the roof. Other problems with this type of roofing is that it is difficult to install, requires a lot of maintenance and the tile and slate is very fragile after installation. Just walking on the roof may cause the tiles to break or crack. Advantages to this type of roofing material is that it is fire proof and long lasting.
Engineered rubber or plastic roofing is long lasting. It is estimated that it will have a life span of about 30 to 50 years, although it is relatively new to the market. This material is very lightweight and is made from recycled materials. Wood shingles, also known as shakes, are expensive to install and create an additional fire hazard for your home unless they are pressure treated. They do help with the insulation as well as blend in with the surroundings. Asphalt shingles are relatively inexpensive and easy to install. However, they are environmentally unfriendly and have a tendency to mold or mildew.
