Because of the huge variety of roof design on residential buildings, a roofing contractor has to be able to work with many different kinds of material, and with different types of roofs such as pitched or flat. The climate will play a large part in determining what type of roof there is: pitched roofs, for example, are common in all climates, but in areas with more severe weather, flat roofs are rarely used due to the chances of heavy rain or snow.

Pitched Roofs

If you have a pitched roof, then there are some specific considerations when it comes to roofing work. Becasue pitched roofs use different materials than flat roofs, roofing contractors need to be familiar with when and how to the various materials. Composition shingles made from asphalt are the most common material used for pitched roofs, but the exact type used can vary. Thinner, organic composition shingles are more fragile than their fibreglass counterparts, which are thicker and more flexible. Dimensional shingles can also be used for pitched roofs. These are the thickest shingles available, and are popular because they allow for a customized appearance which can blend in with the design of a home.

Another roofing material which can be used is metal shingles. Because these are becoming more common nowadays, roofing contractors need to be able to install metal roofs as well. They are popular because they last around twenty years longer than asphalt roofs, if installed correctly, and come in a large range of designs and colours. A roofing contractor needs to be familiar with all these aspects of metal roofing so they can help the homeowner make a good choice for their home in terms of design and reliability. Cedar shakes, tile, and slate are the other roofing materials that a contractor should be able to install. These are more expensive than metal and asphalt, and so are less common. Because they are more difficult to install, contractors who work with them are often specialists in tile, slate and cedar shakes.

Flat Roofs

Flat roofs are identifiable by the fact that they have a small rise of around 7 centimetres leading to a run of around 30 centimetres which allows water to flow to the edges of the roof and stops it pooling in the middle. The benefit of this design is that it can help prevent water damage and leaks. Metal is the most common material used for flat roofs. Metal roofs are adaptable, and come with a galvanized coating which prevents oxidation and corrosion on your roof. Metal roofs can also cost less because the structural support they need from a home is less because of their light weight. The life span of a metal roof is also very good, around fifty years, which is much more than cheaper materials. Metal roofs require minimal maintenance, and so may prove to be cheaper in the long run.
