Asphalt roofing shingles are one of the most cost-effective and common types of roofing materials you can use. They are made of either organic material, or fibreglass, and can last for up to fifty years. Although they are not the most attractive roofing material, there are some ornamental asphalt shingles available nowadays that can add to the aesthetic appeal of your home. Asphalt shingles are made to deflect rain and snow, so they can only be used on pitched roofs, not flat.
Asphalt shingles are very reasonably priced, usually $60 to $100 per square metre. For pitched roofs, this is the cheapest material available, although for flat roofs there are cheaper options such as tar or roll roofing. When installing asphalt shingles, the main thing you need to consider is the ventilation. This is important so that there is sufficient air circulation in the attic space beneath the roof. Generally there should be one vent per 90 square metres. Half the vents should be near the ridge and the other half should be by the eaves. This will prevent moss build up, and if done properly will ensure the roof lasts for a very long time.
The mid-range roofing materials in terms of price are metal and rubber. Metal is the more popular, and lasts for about fifty years. It also offers a lot of choice in terms of colour and design, such as imitation tile and slate. Both rubber and metal are somewhat able to deflect the sun, which helps reduce energy costs in warmer climates.
Cedar shakes, tile and slate shingles are the most expensive materials in relation to asphalt. While cedar shakes are environmentally friendly, they often need to have fire retardant added in order to meet fire safety standards. Tile slates, while lasting for many years, are very heavy and are easily broken during the installation process. Slate is by far the most durable material, lasting over one hundred years, and requires very little maintenance once installed. However, slate installation can be tricky, and it is important to get an expert team for the installation to make sure it is done properly.
