Galvalume Roof Energy Savings

Major roof costs include upfront installation materials and labor and ongoing maintenance repair recoating and cleaning.

Galvalume roof energy savings.

If the roof maintains a more constant temperature however there is less stress on the roof from thermal shock thus making the product more durable and last longer. And galvalume as well as kynar 500 coated and coolroof rated g 90 steel offers exceptional heat reflectivity resulting in lower energy load on homes and hvac equipment resulting in improved interior comfort and energy savings for homeowners. Lighter color roofs reflect sun s heat much better than darker colors. In the photo above we are beginning to see the failure of the paint finish along the seam of the bent metal.

Additional cool roof costs include specialized materials and labor. Cool roofs can save money several ways including energy savings rebates and incentives hvac equipment downsizing and extended roof lifetime. Cool metal roofing systems help reduce the energy need of air conditioned buildings and makes. This highly reflective coating uses cool pigments in the paint to increase solar reflectance and lower the surface temperature of the roof.

The main disadvantage of galvalume steel roofing material is the initial cost of the product which is double the cost of a shingled roof. Such a roof can be reasonably expected to be some 50 to 60 degrees cooler than a dark color asphalt shingles roof. Metal roofs are probably the most expensive first cost cool roof solution but they also have a favorable life cycle cost which shouldn t be ignored. Even at r50 cool roofs can produce a measurable cooling energy savings compared to a low albedo roof even if it comes without a noticeable difference in comfort for the occupants.

Although there are inherent benefits in the use of reflective roofing before selecting a roofing product based on expected energy savings consumers should explore the expected calculated results that can be found on the department of energy s roof savings. Noncombustible class a rating. Painting and maintaining aging galvanized and galvalume roofing. This good thermal reflectivity translates into energy savings by reducing cooling costs in the summer and heating costs in the winter.

Good thermal reflectivity properties assists with energy savings year round. The most effective energy saving finish for metal roofing is commonly referred to as cool metal roofing. Tests have shown that only half as much heat from solar radiation is transmitted into a building fitted with a galvalume roof compared to a galvanized roof and almost one third less heat compared to a terra.

Yet none of the energy savings will be realized if the energy star rated material is not properly installed. It is common for many buildings to use galvalume roofing as an initial cost saving measure.
