When most people are considering which material to use for their roof, they often only think about asphalt or slate roofing material. However, these two materials are really at opposite ends of the spectrum of roofing materials available today, depending on what kind of roof you have.
For example, if you have a pitched roof you can choose from cedar shake, compositional asphalt shingles, dimensional shingles, tile, slate, and metal. Pitched roofs are often found on residential or commercial buildings in areas with more severe weather such as heavy rain or snow. For flat roofs (those with a rise of around 7 centimetres leading to a run of around 30 centimetres), you can pick from materials such as tar, gravel, modified bitumen, roll, metal, EPDM rubber, and PVC mepane materials.
Strength and Value
EPDM (ethylene propylene diene monomer) is a rubber material which can also be used by flat roofing frederick md contractors. It is more expensive than asphalt roofing materials, but is still a mid-range material. It is simple to install because it is laid in a single layer, unlike the messy multiple layers of tar and gravel roofs. Rubber will last much longer than tar, gravel, or bitumen, around five to ten years longer.
Because EPDM rubber roofing requires a more rigid insulation sheet than other roofing materials like metal, where the insulation is part of the material, it is important that you hire a roofing contractor who is familiar with EPDM. This material can give a limited level of UV protection by deflecting the sun. In hotter climates, this can help in lowering energy costs. Rubber is more resilient than tar, gravel or bitumen, and so will last longer without needing significant roof repairs Perth.
Another heat reflecting material is PVC mempane (or polyvinyl chloride). It is about the same price as EPDM, and will also help lower your air conditioning bills. PVC Mempane is highly weather resistant because it doesn’t have any seams due to interior heating, reducing the risk of roof leaks and other damage. This type of roof can last up to thirty-five years if installed correctly. Both these types of rubber roofing are more durable and cleaner than other roofing materials, and are therefore easier for contractors to install.
