Debunking Metal Roofing Myths and Misconceptions
Metal has become one of the most popular roofing materials in recent times, with roofing contractors recommending it more and more to their clients. Despite its popularity, though, myths and misconceptions still persist. Garlock-French Corporation would like to set the record straight by debunking some of these myths.
Metal Roofs Make Too Much Noise
Sheet metal is inherently noisy; this much is true. A properly installed metal roof, however, is anything but noisy. This myth likely stemmed from when metal roofs were used on sheds; the lack of a roof deck certainly makes a racket when it rains.
Today’s residential roofs are far more advanced than a shed. A roof deck with an underlayment deadens sound, and when combined with attic insulation, metal roofs are actually much quieter than asphalt shingle roofs.
Metal Roofs Prevent Ice Dam Formation
Ice dams are formed by improper attic ventilation and poor insulation, and are not affected by the roofing material itself. When trapped heat from the attic radiates through the roof, it melts the snow, which then flows and refreezes as it reaches the roof’s edge, accumulating until it forms a dam. You can prevent ice dams by ensuring your attic is properly ventilated and insulated.
Metal Roofs Reduce Indoor Heating Requirements
A properly-insulated thermal envelope can help reduce your indoor heating requirements during winter. The idea is to prevent heat loss, which prevents heat from escaping, thus minimizing the need for your heating system to compensate. This level of energy efficiency can be achieved regardless of the roofing system.
Still, “cool roofing” features can be added to new or existing metal roofs through light-colored or specially designed reflective coatings. By reflecting the sunlight back up, less heat is absorbed through the roof, helping reduce your indoor cooling requirements.
Metal Roofs Are Prone to Lightning Strikes
Lighting does not selectively hit structures with metal on it; rather, it strikes the tallest grounded structure in the area, regardless of material. This means that unless your home happens to have an extremely tall spire or is standing alone in the middle of a field, then your home isn’t likely to get hit by lightning, metal roof or no metal roof.
