Step 4 slopes.
Gambrel roof hip shingles.
Enter the pitch of the upper roof rise 12 enter the pitch of the lower roof.
Step 5 ridges.
A traditional hip roof consists of four equal length slopes that meet to form a simple ridge.
There are variations though such as a half hip that features two shorter sides with eaves.
Move slider or directly enter angle to alter sweep angle of lower rafters and change the shape.
Step 3 shingle slope.
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.
Gambrel roof a gambrel or barn style roof is simply a gable roof with a change in slope partway up the roof.
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.
How to install asphalt shingles on a gambrel.
Align the first.
Determine the number of squares of asphalt shingles you will need for covering the gambrel roof.
You will need to begin laying your shingles at an outer most corner of the lowest slope of the roof.
Step 2 complete first row.
Lay the second row of shingles.
Check overhang to calculate rafter overhang equal to the lower level cut at the full rafter depth.
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.
This gambrel roof fits in a semicircle and starts as the top half of an equal sided octagon.
Lay the first asphalt shingle at an outer corner of the lowest sloping face of the gambrel roof.
The shingle starter strip amount of shingles needed is provided in lineal feet and includes a row of shingles along the rakes.
The difference is in the amount of ridge capping you need and the amount you will waste.
To calculate a gambrel roof.
Get some friends to help you shingle the hip roof.
Rise 12 enter the coverage of one pack.
Besides its unique appearance a gambrel roof also serves to maximize the usable floor space in the attic area.
One pack of standard shingles covers.
A square of shingles is usually three.
Have one person lay shingles in the proper place and another person nail shingles down.
Square feet enter a waste factor.
Step 1 lay first shingle.
