PRODUCT COVERAGE CALCULATOR

Sample Product Coverage Calculator and Definitions

​

Product Coverage Calculator:

Calculate the cost per square and the number of Cartons or Squares required.

 

Cost Per 100 sq ft of coverage:

Recommended Exposure divided by Desired Exposure multiplied by Cost per 1 sq Carton/Square

 

Example:  

#1 18" RR Sanded and the desired exposure is 6"

14"/6" x $100 = $234 per 100 square feet of Coverage

 

Example:

#1 16" 5X and the desired exposure is 6.5"

5"/6.5" x $100 = $77 per 100 square feet of coverage

 

Number of Cartons or Squares Required:

Recommended Exposure divided by Desired Exposure divided by 100 multiplied by the total square footage to cover.

 

Example:

#1 18" RR Natural Groove and the desired exposure is 7.5" and the total sq footage is 3200

14"/7.5"/100 x 3200 = 60 ctns (rounded up) required

 

Example:

#1 16" 5X and the desired exposure is 6" and the total sq footage is 2400

5"/6"/100 x 2400 = 20 sqs required

 

Note:

For 1/2 Square Cartons, #1 18" RR or #1 24" RR, need to multiply cartons required x 2

 

Maximum Recommended Exposures for all RR's and Shingles

18" RR Sidewall Shingle    14" Exp  

(Exposures over 8" need to be double coursed,

undercoursing required)

24" RR Sidewall Shingle    16" Exp  

(Exposures over 10.5" need to be double coursed, undercooursing required)

16" 5X Shingle                      5" Exp

18" Perfection Shingle      5.5" Exp

24" Royal Shingle              7.5" Exp

 

Key:

All RR Shingle are re-graded and are a grade above a #1 shingle.
