Step 3 shingle slope.
Gambrel roof hip shingles.
A traditional hip roof consists of four equal length slopes that meet to form a simple ridge.
A square of shingles is usually three.
Step 2 complete first row.
Step 5 ridges.
Align the first.
The shingle starter strip amount of shingles needed is provided in lineal feet and includes a row of shingles along the rakes.
To calculate a gambrel roof.
The steep sections of gambrel roofs are very visible so homeowners should carefully consider the appearance of their roofing shingles.
Enter the pitch of the upper roof rise 12 enter the pitch of the lower roof.
Rise 12 enter the coverage of one pack.
Determine the number of squares of asphalt shingles you will need for covering the gambrel roof.
Lay the second row of shingles.
Have one person lay shingles in the proper place and another person nail shingles down.
Check overhang to calculate rafter overhang equal to the lower level cut at the full rafter depth.
One pack of standard shingles covers.
Get some friends to help you shingle the hip roof.
There are variations though such as a half hip that features two shorter sides with eaves.
Set the first shingle of the second row back a half tab 6 inches 17 centimeters from the edge of first shingle on the first row and so that the bottom of its tabs just touches the tops of the cutout slots on the shingle below.
How to shingle a gambrel roof.
This 1 2 tab has to be cut off where it hangs off the left edge of the gable roof.
The top ridge will be shorter for a hip roof but the 4 hips will add to the amount of ridge capping needed and because of the angles the amount of waste will be higher than for a similar sized gable roof.
Lay the first asphalt shingle at an outer corner of the lowest sloping face of the gambrel roof.
The difference is in the amount of ridge capping you need and the amount you will waste.
This gambrel roof fits in a semicircle and starts as the top half of an equal sided octagon.
Use two stacked shingles cut to form to start the ridge cap at the bottom of the hip ridge and then use one cap in each position up the ridge.
Move slider or directly enter angle to alter sweep angle of lower rafters and change the shape.
Square feet enter a waste factor.
Step 4 slopes.
Besides its unique appearance a gambrel roof also serves to maximize the usable floor space in the attic area.
You will need to begin laying your shingles at an outer most corner of the lowest slope of the roof.
