You may have heard that metal roofing is increasingly popular with homeowners who want a more lasting roof covering. And you should definitely consider metal roofing if you live in a climate or region that makes it extra valuable. Here are five areas of the US where it's especially useful to have a metal roof.
1. The Hurricane-Prone East Coast
The East Coast, especially the portions between Virginia and Florida, are especially likely to suffer from tropical weather systems. Now, even a metal roof won't withstand a direct hit from a hurricane, but this region's susceptibility includes not only hurricanes, but also tropical storms, which metal roofs can effectively withstand.
A shingle roof could be totally compromised and require complete replacement in a big storm. And tropical storms, which may come through the area several times per year (depending on where you live along the coast), can have a similar effect on asphalt shingles.
While you may still need roof repairs after a storm goes through (for example, if debris landed on the roof and dented it), metal roofing has one of the highest wind-resistance ratings available. Even if your building is hit by just the edge of a hurricane, escaping a direct hit, a metal roof could make all the difference.
2. The Southwest Desert Regions
If you're looking for a cool roof in a hot place, metal roofing is a popular choice. That's because metal not only has natural reflective properties to reduce the amount of heat it absorbs, but you can also put a cool roof coating on it, unlike asphalt shingles (you're likely to void the manufacturer's warranty if you put a coating on asphalt shingles).
By keeping your attic cooler, a metal roof can help reduce heat transfer to your home's living spaces. This keeps you cooler and helps reduce your energy usage during the summer.
3. The Snowy Northeast
In the opposite direction, snowy climates also allow metal roofing to come into its own. Metal roof shingles or panels are super lightweight, meaning they can allow the roof to support a greater snow load. But the metal also allows snow to shed more easily, sliding down the roof slopes to the ground.
It may seem odd that a type of roofing well-suited to hot climates is also ideally suited to cold climates. For example, some people argue that you should have a dark roof surface in the North in order to absorb the sun's heat. However, when the days are short and the sun is low in the sky and your roof is covered with snow, even asphalt won't absorb much heat anyway.
4. The Sunny California Coast
In regions with cool nighttime temperatures and warm hot daytime temperatures, such as San Francisco in summer, asphalt shingles can experience a type of heat damage known as thermal shock. Thermal shock causes buckling, cracking, tearing, and other shingle problems.
Thermal shock happens because of excessive swelling and shrinking (caused by temperature changes) that the shingle's elasticity can't keep up with. Unlike typical roofing shingles, metal doesn't rely on UV- susceptible asphalt for elasticity, so its expansions and contractions can continue year after year.
5. Wildfire-Affected Areas
In addition to wind resistance, metal roofing can offer remarkable fire resistance as well. However, this depends on what type of metal the roof is made of. If you do live in a fire-prone area, you need to choose a metal with a high melt point. After all, a roof that doesn't catch fire won't save your house if that roof melts right off.
The types of metal roofing with the highest fire resistance are types such as copper and galvanized steel. These are also more expensive than aluminum, however, so it's a tradeoff.These are just five areas where metal roofing can offer you even more of an advantage than usual.
