Cost is often a key factor when you need a new roof for your home. Many people consider saving money by choosing energy-efficient products a top priority. Certain products can help you save significant money on cooling costs. We are happy to report that many of the most well-known roofing products now come in energy-efficient versions. What is the most efficient roofing material for your Florida home’s roof?

Simply put, a reflective roof surface is more efficient in energy efficiency, regardless of whether it is asphalt or metal shingles, tile, metal, or a membrane. A reflective roof allows heat to be transferred into the house at a lower rate. This type of roofing is known as a ” cool rooftop.” Lighter colors such as white, gray, and beige will reflect more sunlight back into space. To increase reflectance, darker colors can be coated with reflective layers.

Another factor that affects a cool roof is thermal emission. This is simply a measure of how quickly a material will emit the heat it has absorbed. This is important for your roof. This is the Solar Reflectance Index (SRI). It combines both these factors to calculate a material’s capacity to reflect sunlight and to also release heat. Higher numbers are better. A highly reflective roof can emit up to 50deg more solar radiation than a traditional roof next door.

Benefits of cool roofs

According to the U.S. According to the U.S.

  • Reduce roof temperature to prolong the roof’s life.
  • You can reduce your energy consumption by reducing the need for air conditioning.
  • Indoor comfort and safety can be improved in spaces that do not have air conditioning.
  • Cooling units that are too small, inefficient, or aging can be used to cool the growing temperatures.
  • It is possible to reduce the size of your AC system, which can save you money and increase cooling efficiency.
  • You may be eligible for money-saving rebates through utilities and government programs.

How to Choose Energy-Efficient Florida Roofing

You may have restrictions on the type of energy-efficient roofing that you can install because your home is part of a homeowner’s group. You might also consider rebates and incentives offered by your utility, the federal government, and manufacturers. To find out if any offers are available, contact your utility providers or your local building department. Who doesn’t like free money?

Asphalt Shingles

The standard asphalt roofing shingle is of great value. You get a lot for the money. GAF cool roofing shingles, for example, are a premium shingle product that comes with a solid warranty and built-in algae prevention. They also have a Class A fire rating. The American classic asphalt shingles are still very popular. Cool roof technology makes them even more attractive. Cool roofs can save homeowners anywhere from 7 to 15% on cooling costs, according to the Cool Roof Rating Council.

You’ll find roofing contractors who are skilled in installing asphalt shingles. This helps reduce your overall cost as it is fast and efficient. One problem with this type of roofing is its recyclability. They can’t be recycled as often as other roofing materials. Metal and tile roofs are more expensive and last for longer. Recycling roofing materials is easier when it comes time to replace them.

Metal roofing

Oak Ridge National Laboratory researchers found that metal roofs with airspace underneath the panels performed just as well as or better than “direct to decking” products like asphalt shingles. This test showed that the shingles were a “cool” color, but not metal. Installing a cool metal roof on top of airspace will result in greater efficiency and a cooler roof surface. Light colors have an advantage over darker colors.

It doesn’t matter if you choose metal shingles or metal tiles. Reflectance and airspace are key ingredients. A substantial warranty is included, sometimes for life.

Clay & Concrete Tile Roofing

Although these roofing materials look similar, clay tiles will last for longer. Clay tile will also cost more so make sure to compare your offers to determine if the additional expense is worth it. Both materials are fitted with battens on the roof decking. This creates airspace between roof tiles and roof decking. This airspace can be used for ventilation or as a thermal break as described in the section on metal roofs. This creates airspace that allows for drainage of moisture beyond the roof tiles. This reduces solar heat that can move into your attic. This is a significant component of stressing your AC system.

Flat Roofs: Membrane and Modified Bitumen.

Although they can all be applied to flat roofs (or nearly flat roofs), these types of roofing are very different. Let’s begin with membrane roofs. These roofs are known as single-layer roofing systems. These roofs are made of a synthetic material that is rolled over the roof. They are usually attached with adhesive but can be “floating” and held in place by fasteners or ballast. Ballast is a layer made up of heavy gravel, but it is not attached to the membrane.

There are many different types of materials, but the most important thing for energy efficiency is their color. EPDM is often dark, while TPO and PVC can be white. This makes a huge difference in the heat transfer to the interior of a building.

These materials almost always are installed over rigid insulation. This insulation blocks most of the heat coming from darker EPDM roofing membranes. The heat transfer can be reduced by installing more rigid insulation between the membrane and roof decking. However, with the same insulation, a TPO or PVC roof of a lighter color will have a lower temperature than an EPDM roof. This should result in a lower energy bill.

BUR and modified bitumen can both be improved. This is another layer that can increase the reflective and emissive properties of the material. It will also save you money. The rest of your roof system will remain the same.
