Removal of shingles
es mate for the actual number of squares (not square feet). No es ma ng or rounding
Replacement of shingles
a) Include waste in the calcula on
-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 es mates always end with?
fourths. .25, .5, .75, .00
What do composite shingle es mates always end with?
thirds. .33, .66, .00
Calcula ng Hip Roofs
get main body first. extensions second.
Hip roof triangular ends
are calculated when the main roof is calculated b/c a triangle is accounted for that didn't
actually exist
When calcula ng extensions on a hip roof
don't count for the triangle, but don't forget the two parrallelograms remaining (there is a
good chance they are iden cal)
When calcula ng the main body
Don't assume that you can just find one side of a roof and double it. Why? the ra7ers might
be different lengths
How do you find the height of a hip roof?
the height of the triangle is equal to the length of the ra7er that is forming the
parallelogram
, (only true if the pitch of the roof is iden cal and the angles on the hip roof are 90 degrees)
Do you round when removing a roof?
No, removal is always the exact number
What calcula ons can you use to replace?
x1.10 for composite
x1.15 for wood
.33 for composite
.25 for wood
"drop and roll"
the method for es ma ng carpet
How wide are carpet rolls?
12 feet
What carpet allowance must you make in es mates?
You must add an addi onal 3" for length. If you forget this, then you get the ques on wrong!
It is ok to change the way carpet seams are run in a house
False
How do you calculate the removal of carpet
It is the actual square footage
What do Removal of carpet & Replacement of carpet pad have in common?
they both are the actual square footage
Xac mate 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?
The answer: square footage
To calculate floor removal:
divide up into squares/rectangles and determine specific amount to be removed
To calculate replacement of floor:
