When matched to the angle and proportions of other rooflines on the house your gable roof will add visual interest and character to the home making the addition look like an asset that belongs with the house.
How to add a peak on a roof.
Cut it to size using a box knife and install with a staple gun.
Since pitch is the rise over a 12 inch run divide the run by 12 to get the multiplier in this case 120 12 10.
Step 4 re sheath roof.
They form an upside down v with the point at the top of the addition roof.
Cut two rafters with a circular saw to the pitch of the addition roof and nail them across the rafters on the old roof.
Step 3 prepare the materials.
Start by installing tar paper on top of the plywood.
Rather than a single slope a gable roof consists of two slopes that meet at a peak running down the middle of the roof.
Nail the shingles to the felt starting from the outside in and cutting to fit when you reach a corner or edge.
The run or half the building span is the base of the triangle.
Step 2 calculate material prices.
For your first row of shingle at the bottom of the roof place a shingle piece with the solid side overhanging the drip edge feels upside down by 1 4 and install using roofing nails.
Once the trusses soffit and fascia are in place lay the roofing felt in place.
Set the power saw s blade depth to the thickness of the sheathing and any remaining shingles about 3 4 inches to 1 inch.
Step 1 calculate the roof span.
Step 5 replace roofing.
The rise or height of the roof at its peak is the altitude of the triangle.
Adding pitch to a flat roof.
Nail the trusses into the existing room fasteners.
Now you can begin shingling your roof preferably with asphalt shingles.
Calculate how much the roof span is going to be by measuring from one top plate to the other top plate.
And the line length measurement from the roof peak to the building wall is the hypotenuse.
