State Farm Estimatics Exam
Removal of shingles
(Ans- estimate for the actual number of squares (not square feet). No
estimating or rounding
Replacement of shingles
(Ansa) 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?
(Ansx1.10 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?
(AnsCarpet (Not carpet pad), need to add waste

What do Removal of carpet & Replacement of carpet pad have in common?
they both are the actual square footage
Xactimate doesn’t calculate waste on what three things?
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?
divide up into squares/rectangles and determine specific amount to be removed
To calculate replacement of floor:
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
How much would it cost to replace the linear feet of truss on this roof?
(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?
the bottom chord…which does not include the overhangs
How do you calculate the painting of walls and ceiling?
You will always have 3 measurements
similar to trade breakdown (DRY = Drywall, RFG – roofing, etc.)
Selector Code (Identifies a specific item within a category)
This is a 3×5 vinyl window, how much would it cost to replace?
Do the math, find its a 15sf window, look up the grade, find the correct size, botta bing
Xactimate descriptions are “general” or average.
There are this many squares (41.6) to remove. How much is the removal cost?
Look at price list under “remove” and multiple by that number (31.18): 41.6 x 31.18 = 1297.088
How will they try to trick me in the pricelist?
[(Base1 + Base 2) / 2] x Height
PAI-r-squared (r squared first, then multiply by PAI)
What size door (any opening) do we deduct for?
What is the square footage of a 3’0x6’8″ door?
Where do we take a measurements from on an opening?
What are out of the other ordinary openings?
fireplace/mantle, back splash, bookcase, garage door
A place there is no trim. Only deduct for 3/0x6/8
Painting around openings and trim
professional painters rarely mask…don’t include it in the estimate
What are the parts of a truss?
What is not a component of a truss?
from end wall to end wall. (not overhang)
# of trusses x span of one truss
[length of building in inches / O.C. in inches] + 1
Deck
Rake
Flashing
Valley
Ridge
Dormer
Eave
a)Attached to top chord of truss and supports roof rafters
b) forms the deck
What is solid sheathing used for?
composition shingles because it is smooth in application
What is spaced sheathing usually used for?
What size spaced sheathing is usually used with 5.5″ wood shingles?
What is a benefit of spaced sheathing?
Can you use solid sheathing for wood shakes/shingles?
What are the three most common composite shingles?
1) T-Lock (angular cuts)
2) 3 tab (plain jane)
3) Laminated (give a layered…wood like look)
What are comp shingles made of?
fiberglass or asphalt-saturated embedded with mineral annuals
What is the weight base of comp shingles?
a) 3 bundles per square
b) range from 200 to 240 lb
c) light to medium weight shingles
Shingle test question: it is possible to buy 3 or 4 bundles per square
What type of fiberglass roof can be rigid? corrogated or greenhouse?
I have no idea, but its a test question
What are standard lengths of wood shakes?
How many bundles per square do wood shakes/shingles come in?
What are rigid roofing materials?
shingles/tiles made of: clay, aluminum, steel, copper, fiberglass, concrete, slate or plastic
by the piece, in bundles or in squares
deteriorate easily
are more durable than other roofing materials
What roofing material is heavier?
What roofing material requires more labor to install?
What are three basic roof types?
What are additional roof vents? do i know what they look like?
Usually seen in barns, but can be in homes too. Looks like a tower top
-protect framing, insulation, and interior from weather
What are the two categories of exterior finishes?
brick veneer
stucco
concrete block
stone
glass blocks (for some windows)
(Masonry) common stone products
granite, sandstone, marble, slate, limestone

reverse board and batten
t1-11
Whats the main problem with wood siding?
Its more vulnerable to deterioration and needs periodic paint or stain to protect it
has a baked on enamel factory finish that can look like wood
requires little maintenance
Made of PVC (Rigid Polyvinyl-chloride)
durable and economical
can be different thicknesses
What can vinyl siding be installed with?
A backer board for:
-insulation
-rigidity
-strength
-increases the R-Value
-More durable than vinyl, aluminum, or vinyl clad siding
-Steel can be discovered by use of a magnet
underneath side of the roof overhang or eave in a closed cornice
usually plywood, aluminum or vinyl
What type of soffit will likely have a vent cut into them?
what soffits will be solid or have a perforations?
Who installs aluminum or vinyl soffits?
How is soffit material estimated?
Any material that resists the passage of heat into or out of a building
Surrounds living or work areas and foundations
installed in floors, walls, ceilings or attics
a roll of precut thicknesses to fit standard wall cavities
1) Paper- (kraft) backed insulation has paper on one side
2) Paper is a vapor barrier
3) paper also acts as a air infiltration reducer and keeps water from being trapped in the barrier
4)moisture in insulation reduces it r value
5) foil backed insulation – does the same as paper but reflects heat back into the room
6) Unfaced – (Aka friction fit) has no backing. Usually contractor will cover with plastic in order to provide a vapor barrier
a treated, ground up newspaper that is blown into wall cavities and attics. normally grey in color
is a white, Styrofoam-type material used primarily to fill cavities in masonry-block walls
is a tan, Styrofoam-type material used primarily to fill cavities in masonry-block walls
Shredded-fiberglass Insulation
is blown into wall cavities and attics; it is normally white in color
