UPDATE!!!2025/2026|GUARANTEED
Removal of shingles - ANSWER estimate for the actual number of squares (not square
feet). No estimating or rounding
Replacement of shingles - ANSWER 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? - ANSWER fourths. .25, .5, .75, .00
What do composite shingle estimates always end with? - ANSWER thirds. .33, .66, .00
Calculating Hip Roofs - ANSWER get main body first. extensions second.
Hip roof triangular ends - ANSWER 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 - ANSWER don't count for the triangle, but
don't forget the two parrallelograms remaining (there is a good chance they are identical)
1
, When calculating the main body - ANSWER 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? - ANSWER 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? - ANSWER No, removal is always the exact
number
What calculations can you use to replace? - ANSWER x1.10 for composite
x1.15 for wood
.33 for composite
.25 for wood
"drop and roll" - ANSWER the method for estimating carpet
How wide are carpet rolls? - ANSWER 12 feet
What carpet allowance must you make in estimates? - ANSWER 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 - ANSWER False
How do you calculate the removal of carpet - ANSWER It is the actual square footage
