Many people still labor under the illusion that metal roofs are expensive, noisy and hold heat.

WRONG!

Once upon a time the tin roof shack, absent a ceiling was noisy. But today’s metal roofs built over a roof of plywood with insulating padding, available in a variety of thicknesses and materials, is quiet. They all also com equipped with what is technically referred to as “underlayment layer”. Some of the choices available today for that insulation layer are asphalt saturated felt material, Synthetic blanket or sheet material, or a rubber mat like material with an adhesive facing.

This plays a critical role in the four barriers that must be in place in any home or building. These barriers are designated the (a) air barrier, (b) the vapor barrier, (c) the heat or thermal barrier and of course (d) the water barrier. Here is South Florida we know about the rain barrier.

Metal roofing today comes in a variety of shapes, sizes textures and colors, some that look amazingly like traditional roofing materials other reflect a simpler time. Even a variety of materials are also in use today; copper, aluminum, steel, and even stainless steel. Regardless of what material you choose, you must know that if your criteria for selecting roofing material is durability and energy efficiency METAL my friend, is the choice for you.

Installation of reflective metal roofing can save your home up to 40% in summer cooling energy costs while highly emissive metal roofs can reduce urban air temperatures by as much as 12 ° F.

Combined, these benefits mean less money out of your wallet, and less dependence on expensive energy resources and ultimately a smaller energy footprint in your neighborhood. [source: OAKRIDGE NATIONAL LABORATORY]

Asphalt shingles although still widely used, tend to hold heat and release it very slowly. That warm heated shingle tends to emanate heat to the surrounding air, heating the area below the roof as well as above. This has been calculated to contribute as much as 20-25 degrees F to indoor air. Increasing the energy use in the home. [source: Florida Solar Energy Center].

Alternatively metal roofs reflect solar radiation, deflecting it away and reducing the thermal impact, which in Florida, means energy savings. Metal roofs have been shown to cut thermal penetration by approximately 50 percent, and can produce a 100 degrees temperature differential, on its surface compared to traditional asphalt roofs [source: MRCA]

Shingle roofs and tile roofs tent to react more to wind and debris and typically require more maintenance than a metal roof. A metal roof reflects rather than absorbs the thermal stress and temperature variation, and is tremendously unaffected by the elements when correctly installed.

METAL BENEFITS

LOGEVITY: One big benefit, a metal roof can last up to 70 years.
Asphalt Shingles at best 20 years

DURABILITY: Metal roofs have withstood 140 mph winds, will not crack or corrode and are
largely impact resistant.

SAFETY: Metal roofs are not susceptible to sparks from nearby fires

ENERGY EFFICIENCY: Metal roofs reflect solar rays, and cut energy costs as much as 25%
