Rather than following the traditions of times, modern buildings can be built to many different styles and specifications, depending on the personal taste of the person who is paying for the construction. Along with the overall style of the building, another aspect that should be thoroughly considered is the type of roofing that will be installed.
The budget is usually the main priority of homeowners when they are considering the roofing options available to them, but actually there are a few more important points to bear in mind that tie into the budget. Some examples of these are the projected maintenance costs, the life expectancy of the material and any possible benefits that could be associated to installing a certain roofing material such as reduced energy bills or an increased house value.
The type of roofing you can choose first and foremost comes down to the angle of your roof. A flat roof is defined as a roof with an incline where the lowest point is no less than three inches below the highest point. Flat roofs can be fitted with metal, gravel and tar, modified bitumen, rubber, foam or an eco-friendly grass and soil topping. Slanted or pitched roofs can have clay or concrete tiles, wood shingles, slate or synthetic slate tiles, or metal such as aluminum.
Different types of pitched roofing are popular in different countries. In the United States, composite shingles made from asphalt is the most popular, while around the Mediterranean and much of Asia, clay tiles are more popular. This is partly due to the cost and partly due to the properties of the materials. There are compromises to be made with all types of roofing. If you want the cheapest material for your pitched roof, then expect to have to replace the roof at some point as soon as ten years after first install. If you want the most expensive (slate), then you should probably expect to be outlived by your roof!
One of the rising stars of the roofing world at the current moment is SPF, or spray polyurethane foam. What is great about this material is that it can be sprayed onto any exterior surface, smoothed and then dried within one day by only a small team of people. It is relatively cheap to install, lasts well and is excellent at insulating against heat loss. Foam can be used for pitched and flat roofs along with metals such as steel, aluminum or copper. If you want something a bit more eco-friendly for your flat roof, then you could consider installing a green roofing system. These systems are made up of a number of layers providing waterproofing and other membranes and then finished off with vegetation. They are very impressive at heat insulation and also give your home a very unique look.
