In short, dimensional shingles is an asphalt shingle with a thin, airy edge. Dimensional shingled, also sometimes known as flat roofing shingled, have in fact been popular for many years, but as new, more attractive, choices come on the market, the question of just what they really are continuing to rise. What most people may not know is that the term ‘durable’ itself is misleading. While asphalt shingle roofs do stand up well to the elements and are fairly low maintenance, they have one major weakness – the appearance. Asphalt shingle roofs have a completely different, factory make appearance that makes them seem cheap and unappealing.
While some people believe that because these shingled roofing systems are so durable, they are therefore immune to weathering, the truth of the matter is a little different. Asphalt shingle roofs do in fact benefit from natural conditions and are thus able to weather to a degree where other types of roof systems can not. That said, with a lower amount of natural moisture in the air, they do stand up less well to environmental conditions and thus are somewhat less resistant to weathering. This is one major reason why dimensional shingles have become such a popular choice for recent years – because they are able to withstand a greater number of environmental and climate changes that might otherwise damage more traditional asphalt roofing systems. In fact, it has been found that while single layer asphalt shingling systems were vulnerable to weathering, double layer systems were much less so.
Finally, while they do help prevent more intense winds from blowing into a home, it should be noted that they do not actually provide any sort of wind break. What this means is that instead of helping to disperse any strong winds that may be in the area, they actually make those winds stronger, which can lead to significant increases in the cost of roof replacement costs. It should also be noted that while they can help prevent more intense winds, they cannot in any way reduce the strength of a hurricane or tornado. In short, if you live in an area prone to strong winds, you would do better to invest in an alternative form of roofing such as shingle roof replacement.
