• Rooftops can be replaced with clay, concrete, and metal.rooftop image by Vitezslav Halamka from Fotolia.com
  
  Residential roofs typically do not last longer than 20 years without developing significant problems that cause homeowners to consider replacing the roof completely. There are a variety of roofing materials on the market, including those that many people do not consider for residential roofs, including metal and concrete. Homeowners should carefully consider their budget and the specific qualities of their climate when pondering roof replacement.
  
  

Clay Tiles

• Clay tiles are made in a manner similar to ceramic tiles, shaped and then fired in a kiln. These tiles come in a variety of clay-red shades and can be either interlocking or overlapping. The tiles are heavy and cannot be installed on steep roofs, but they are common in desert areas because of their natural appearance and their high resistance to heat.
  
  

Concrete Tile

• Concrete tiles are made in ways similar to clay tiles: manufacturers extrude the concrete into molds and dry it. Concrete typically comes in a wider variety of shapes and styles than clay. The tiles can be designed to imitate a variety of other substances, especially natural rock, which homeowners may prefer. Concrete is also heavy and needs to be installed carefully.
  
  

Cedar Shingles

• Wood shingles give homes a classical look, and the warmth of wood works well for many houses. The most common material for wood shingles is cedar, which may be pressure-treated or covered with protective coatings. Cedar shingles are not fire-resistant, so they may not work well in areas where fires are common (some towns have restrictions against them), but they can last as long as asphalt shingles. Shakes are wood shingles that are hewn by hand and offer a rougher look.
  
  

Metal Roofing

• Another roofing option involves using panels and sheets of metal like aluminum, copper, and stainless steel to cover the house. These roofing materials work well for contemporary looks, and some metal roofs are made to resemble tiles. Others are sprayed with protective substances that give them a natural grainy appearance. Metal can be noisy and is the most expensive option, but it protects well against sunlight and is long-lasting.
  
  

Rubber

• Rubber membranes do not form the top layer of the roof, but are installed underneath it to offer an extra layer of protection against the elements. If homeowners live in areas where rain is common, they should consider installing a rubber membrane before the top layer of tile or shingles.
