Another factor is climate.
Slate roof energy efficiency.
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.
The energy star energy efficiency criteria do not include a specification for roof insulation.
Standard or dark roofs can reach temperatures of 150 f or more in the summer sun.
That s because dark asphalt shingles a common roofing choice for homeowners absorb sunlight and convert.
Metal roofing is also passive house ready in several key areas.
Environmental protection agency s energy star program began rating roofing materials for energy.
On a clear day your roof can be dangerously hot.
Slate roofing is a stunning energy efficient roof option that can last a lifetime.
The popularity of metal roofs has soared in recent years because of their durability energy efficiency and environmental performance.
Metal roofs protect their insulation backup better which ensures strong long term thermal resistance.
Due to their durability and energy efficiency they have significant cost saving potential.
Some of the most energy efficient roof material and color include.
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.
This is especially true of.
A darker energy star rated roof will usually outperform a lighter roof that isn t designed with efficiency in mind.
So in 1999 the u s.
Reflectivity requirements differ for low slope and steep slope roofs.
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.
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.
A cool roof under the same conditions could stay more than 50 f cooler and save energy and money by using less air conditioning.
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.
