ONDURA ESTIMATING
FASTENERS:
SQUARE FOOTAGE OF PROJECT AREA * 1.65 = ESTIMATED FASTENERS NEEDED
(REGULAR INSTALLATION)
SQUARE FOOTAGE OF PROJECT AREA * 2 = ESTIMATED FASTENERS NEEDED
(HIGH WIND INSTALLATION)
CLOSURES:
TOTAL THE LENGTH IN INCHES OF THE EAVES, PLUS TWICE THE LENGTH OF THE RIDGES, AND FOUR
TIMES THE LENGTH OF THE HIPS AND VALLEYS. DIVIDE THE TOTAL INCHES BY 44 (THE LENGTH OF
THE CLOSURE STRIP IN INCHES) TO GET THE NUMBER OF CLOSURES NEEDED.
(NOTE: 4 CLOSURES/PACK)
RIDGE CAPS:
RIDGE LINEAR FT * 12 = RIDGE LINEAR INCHES
LINEAR INCHES/34 = ESTIMATED STANDARD RIDGES NEEDED
LINEAR INCHES/73 = ESTIMATED LONG RIDGES NEEDED
LINEAR INCHES/14 = ESTIMATED RIDGE TILES NEEDED
MATERIAL:
ONDURA
 SQUARE FOOTAGE OF PROJECT AREA/22 = ESTIMATED SHEETS NEEDED
ONDURA-9
 SQUARE FOOTAGE OF PROJECT AREA/16 = ESTIMATED SHEETS NEEDED
ONDURA TILE
 SQUARE FOOTAGE OF PROJECT AREA/4 = ESTIMATED SHEETS NEEDED
