Slate Roof Energy Efficiency

A cool roof under the same conditions could stay more than 50 f cooler and save energy and money by using less air conditioning.

Slate roof energy efficiency.

If 20 or more of the slates on a roof or roof slope are broken cracked missing or sliding out of position it is usually less expensive to replace the roof than to execute individual repairs. Slate roofing is a stunning energy efficient roof option that can last a lifetime. Metal roofing is also passive house ready in several key areas. Its density helps to insulate your home making it a very eco friendly choice.

A darker energy star rated roof will usually outperform a lighter roof that isn t designed with efficiency in mind. That s because dark asphalt shingles a common roofing choice for homeowners absorb sunlight and convert. The energy star energy efficiency criteria do not include a specification for roof insulation. While lighter roofs can be a clear choice in the warmest climates homes in cooler climates are often better suited by a darker roof that can absorb a little free heat from the sun during winter.

Another factor is climate. Standard or dark roofs can reach temperatures of 150 f or more in the summer sun. These roofs can last for 40 to 70 years and are recyclable at the end of their useful life. Green roofs clay and slate tiles metal sprayed polyurethane foam and more.

Cool roofs can be made of a highly reflective type of paint a sheet covering or highly reflective tiles or shingles. Due to metal roofing s incredibly efficient solar reflectance and thermal emittance metal is the ideal roofing material for the construction of a net zero energy home. Tile roofing is also a very aesthetically pleasing energy efficient roof option but is best for those in warm dry climates due to its tendency to absorb moisture and reflect sunlight. Reflectivity requirements differ for low slope and steep slope roofs.

So in 1999 the u s. Environmental protection agency s energy star program began rating roofing materials for energy. Metal roofs protect their insulation backup better which ensures strong long term thermal resistance. Energy star certified roof products can help reduce the amount of air conditioning needed in buildings and can reduce peak cooling demand by 10 15 percent.

Some of the most energy efficient roof material and color include. On a clear day your roof can be dangerously hot. The popularity of metal roofs has soared in recent years because of their durability energy efficiency and environmental performance. The hotter the roof the more energy it takes to cool the building beneath it.
