Nowadays, homeowners can chose from a wide range of options in residential roofing material. There are also many different design, texture, and colour choices available, depending on the style of roof you have, that will fit with whatever look you want for your home.
Residential homes normally have pitched roofs, because these are more weather-resistant than flat roofs. Composition asphalt shingles, made from organic material or fibreglass, are the most common material used for pitched roofs on residential buildings. Asphalt is one of the cheapest roofing materials you can buy. You can also get dimensional roofing shingles, which allow you to customize the appearance of your roof. They are also thicker, stronger, and can last for up to forty years, instead of the twenty or thirty of asphalt shingles.
Slate and tile can also be used on pitched roofs, but these are some of the most expensive materials on the market: slate shingles cost around ten times more than asphalt shingles. The upside of slate and tile roofs is that they are the longest lasting material (around hundred years) and require very little maintenance if installed properly.
Flat roof materials are designed for roofs with a small rise of around 7 centimetres and a run of around 30 centimetres. Metal is the one roofing material which is used on both flat and pitched roofs. Metal roofing materials are very adaptable, but are a little more expensive than asphalt. Metal offers many choices in appearance and design, from the most common standing seam to imitation tile and slate. This allows the homeowner to customise the appearance of their roof without the expense of slate or tile. Other benefits of metal roofing include its longevity (around fifty years) and its minimal maintenance requirements.
Other common and inexpensive roofing materials sued for flat roofs include tar, gravel, modified bitumen, and roll roofing materials. Tar and gravel roofs are made of layers of material, which is a very messy process. Roll roofing is very cheap and easy to install, but it has a very short life span of around ten years because it only has one layer of material.
