Double Eagle Ponderosa

Double Eagle Ponderosa is a textured, low-profile concrete roof tile from Eagle Roofing Products. A center bevel suggests smaller hand-split wood shakes and changes the perceived scale compared with the undivided Ponderosa face. The profile appears in residential concrete tile roofing.

It is one of the Double Eagle profiles in Eagle's flat tile range, next to Double Eagle Bel Air. A standard and an Eaglelite weight are both made.

• Nominal size: 17 inches long by 12 3/8 inches wide

• Eaglelite installed dry weight: 7.2 psf, approximately 720 pounds per 100 square feet
