State Farm Estimatics
Removal of shingles ANS: estimate for the actual number of squares (not square feet). No estimating or
rounding
Replacement of shingles ANS: a) Include waste in the calculation
-10% - Composite
-15% - wood
b) Round up to the nearest bundle
-Assume 3 bundles per SQ for composite shingles
-Assume 4 bundles per SQ for wood
What do wood shingle estimates always end with? ANS: fourths. .25, .5, .75, .00
What do composite shingle estimates always end with? ANS: thirds. .33, .66, .00
Calculating Hip Roofs ANS: get main body first. extensions second.
Hip roof triangular ends ANS: are calculated when the main roof is calculated b/c a triangle is accounted
for that didn't actually exist
When calculating extensions on a hip roof ANS: don't count for the triangle, but don't forget the two
parrallelograms remaining (there is a good chance they are identical)
When calculating the main body ANS: Don't assume that you can just find one side of a roof and double
it. Why? the rafters might be different lengths
How do you find the height of a hip roof? ANS: the height of the triangle is equal to the length of the
rafter that is forming the parallelogram
(only true if the pitch of the roof is identical and the angles on the hip roof are 90 degrees)
Do you round when removing a roof? ANS: No, removal is always the exact number
What calculations can you use to replace? ANS: x1.10 for composite
x1.15 for wood
.33 for composite
.25 for wood
"drop and roll" ANS: the method for estimating carpet
How wide are carpet rolls? ANS: 12 feet
, What carpet allowance must you make in estimates? ANS: You must add an additional 3" for length. If
you forget this, then you get the question wrong!
It is ok to change the way carpet seams are run in a house ANS: False
How do you calculate the removal of carpet ANS: It is the actual square footage
What do Removal of carpet & Replacement of carpet pad have in common? ANS: they both are the
actual square footage
Xactimate doesn't calculate waste on what three things? ANS: Carpet (Not carpet pad), need to add
waste
Shingles
Vinyl sheath flooring
How much square footage is it to move and replace the carpet pad? ANS: The answer: square footage
To calculate floor removal: ANS: divide up into squares/rectangles and determine specific amount to be
removed
To calculate replacement of floor: ANS: 1) notice seams in flooring
2) drop and roll a 12' roll of carpet
3) add 3" to length (.25)
To calculate linear feet of trusses ANS: 1) are they installed 24" of center?
2) convert 24" to feet
3) length of roof (30ft) / 2ft = 15 (the number of trusses)
4) Add 1 for the truss not yet accounted for: 30/2 = 15. Then 15 +1 = 16. 16 trusses
How much would it cost to replace the linear feet of truss on this roof? ANS: (total number of trusses) X
(width of roof w/out overhangs) = linear feet of roof trusses
What section of a truss are you using to calculate linear feet? ANS: the bottom chord...which does not
include the overhangs
How thick are stud walls? ANS: 4 inches
How do you calculate the painting of walls and ceiling? ANS: You will always have 3 measurements
Baseboards are linear feet ANS: Just add up the length of the walls (openings only matter if they are
larger than 3'0 x 6'8" or 20.01)
Category Code (Xactimate) ANS: similar to trade breakdown (DRY = Drywall, RFG - roofing, etc.)
