Removal of shingles II! II!
estimate for the actual number of squares (not square feet). No estimating or rounding
II! II! II! II! II! II! II! II! II! II! II! II! II!
Replacement of shingles II! II!
a) Include waste in the calculation
II! II! II! II! II!
-10% - Composite II! II!
-15% - wood II! II!
b) Round up to the nearest bundle
II! II! II! II! II! II!
-Assume 3 bundles per SQ for composite shingles II! II! II! II! II! II! II!
-Assume 4 bundles per SQ for wood II! II! II! II! II! II!
What do wood shingle estimates always end with?
II! II! II! II! II! II! II!
fourths. .25, .5, .75, .00 II! II! II! II!
What do composite shingle estimates always end with?
II! II! II! II! II! II! II!
thirds. .33, .66, .00 II! II! II!
Calculating Hip Roofs II! II!
get main body first. extensions second.
II! II! II! II! II!
Hip roof triangular ends
II! II! II!
are calculated when the main roof is calculated b/c a triangle is accounted for that didn't actually exist
II! II! II! II! II! II! II! II! II! II! II! II! II! II! II! II! II!
When calculating extensions on a hip roof
II! II! II! II! II! II!
don't count for the triangle, but don't forget the two parrallelograms remaining (there is a good chance
II! II! II! II! II! II! II! II! II! II! II! II! II! II! II! II!
they are identical)
II! II! II!
When calculating the main body II! II! II! II!
Don't assume that you can just find one side of a roof and double it. Why? the rafters might be different
II! II! II! II! II! II! II! II! II! II! II! II! II! II! II! II! II! II! II! II!
lengths
II!
How do you find the height of a hip roof?
II! II! II! II! II! II! II! II! II!
the height of the triangle is equal to the length of the rafter that is forming the parallelogram
II! II! II! II! II! II! II! II! II! II! II! II! II! II! II! II! II!
(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?
II! II! II! II! II! II!
No, removal is always the exact number
II! II! II! II! II! II!
What calculations can you use to replace? II! II! II! II! II! II!
x1.10 for composite II! II!
x1.15 for wood II! II!
.33 for composite II! II!
.25 for wood II! II!
"drop and roll" II! II!
the method for estimating carpet
II! II! II! II!
How wide are carpet rolls? II! II! II! II!
12 feet II!
What carpet allowance must you make in estimates?
II! II! II! II! II! II! II!
You must add an additional 3" for length. If you forget this, then you get the question wrong!
II! II! II! II! II! II! II! II! II! II! II! II! II! II! II! II! II!
It is ok to change the way carpet seams are run in a house
II! II! II! II! II! II! II! II! II! II! II! II! II!
False
How do you calculate the removal of carpet
II! II! II! II! II! II! II!
It is the actual square footage
II! II! II! II! II!
What do Removal of carpet & Replacement of carpet pad have in common?
II! II! II! II! II! II! II! II! II! II! II! II!
they both are the actual square footage
II! II! II! II! II! II!
