Despite their versatile uses, high durability, and increasing popularity, metal roofs still suffer from the prevalence of erroneous myths. Unfortunately, that means many people to capitalize on the incredible benefits of a metal roof. If you would like to ensure that you know the whole story about metal roofing, read on. This article will debunk two of their most stubborn myths.
Installing a metal roof involves significant structural alterations.
This myth has a lot to do with the physical makeup of metal roofs. After all, people reason, metal tends to be a dense and heavy substance, so it makes sense that a roof would need to be seriously strengthened before having metal sheathing installed. Yet what this notion fails to take into account is that metal roofing panels are actually quite light. In fact, depending on the specific material being used, a square foot of metal roofing often turns out to weight less its asphalt shingle equivalent.
Therefore, you can safely assume that your house will likely not require any alterations before having a metal roof put on. Not only does this hold true in the majority of cases, but it is frequently possible to have a metal roof attached directly atop an existing asphalt shingle roof. This allows you to save the money you would otherwise spend having a roofing company painstakingly remove all of those shingles.
Heat can escape from a metal roof with much greater ease.
This mistaken idea has its basis in the fact that many people remain largely unfamiliar with metal roofs. When they think of one, the picture that comes into their head is generally of some sort of tin shed--complete with leaks, drafts, and other signs of decrepitude. Fortunately, this conception of metal roofing is way off base. In fact, in most cases a metal roof represents a significant upgrade in terms of overall energy efficiency.
This fact has a lot to do with the fact that, rather than sitting flush against the sheathing, a metal roof is installed on top of what is known as a strapping system. This system amounts to a wooden lattice created using 1x4 boards. It acts to separate the metal from the roof, thus creating pockets of air that act as thermal insulators. In some cases, to further boost the roof's ability to keep heat from escaping, rigid insulation is installed inside of the gaps in the strapping system.
