"When itx27s time to have your homex27s roofing replaced, or if you have a new home built and need to choose the type of roof it will have, you might consider metal rather than standard asphalt tiles and shingles. There are many reasons why metal is a good choice for either a new home or as a roof replacement; note a few comparisons between these two materials so you can determine the right choice for your home.\nDurability\nBecause metal roofs are installed in long sheets, they are much less likelyx26nbsp;than standard asphalt tiles and shingles to come up and blow off the home in severe weather. Metal sheets also wonx27t come loose in small areas of the roof as do individual tiles and shingles; this can mean less risk of water leaks and damage to the home under those individual tiles.\nAdditionally, asphalt shingles and tiles might become brittle and cracked so that parts of each tile fly away or get crumbly and loose, also allowing for water leaks in those areas. Metal is much more durable in all these ways than a standard asphalt roof.\nColour\nA metal roof can be powder coated, which is a type of colouring that is applied in powder form and then adhered to the surface with an electrical charge. Not only does this allow you to choose a unique colour for your homex27s roof, but the colour you choose is typically going to last longer and stay truer than the colour of asphalt tiles. Older asphalt shingles and tiles may easily fade under direct sunlight and after being exposed to harsh weather conditions, whereas a metal roof thatx27s been powder coated will keep that colour for many years, if not over the lifetime of the roof itself.\nRoofing layers\nA metal roof can often be applied right over asphalt shingles and tiles, as itx27s very lightweight and can be fabricated to fit over those tiles easily. If you install a metal roof and then it gets damaged for any reason, you can also typically add a coating over that damaged area to seal up any cracks or dents, without having to put on an entirely new roof. You can also add a new metal roof on top of a pre-existing metal roof, and you may be able to do this more times than if you have an asphalt roof. This can save you the cost and mess of a roof tear-off and of the replacement of asphalt shingles and tiles.x26nbsp;\nFor more information contact a metal roofing professional."
