Step 4 re sheath roof.
How to add a peak on a roof. 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. 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. Now you can begin shingling your roof preferably with asphalt shingles. Nail the shingles to the felt starting from the outside in and cutting to fit when you reach a corner or edge.
Step 5 replace roofing. Rather than a single slope a gable roof consists of two slopes that meet at a peak running down the middle of the roof. Step 1 calculate the roof span. And the line length measurement from the roof peak to the building wall is the hypotenuse.
The total run is the distance from the peak to the edge of the roof which in this case is the total width divided in half which is equal to 10 feet or 120 inches. Calculate how much the roof span is going to be by measuring from one top plate to the other top plate. Set the power saw s blade depth to the thickness of the sheathing and any remaining shingles about 3 4 inches to 1 inch. The run or half the building span is the base of the triangle.
Create the slot by cutting through the sheathing along each chalk line on either side of the peak. Start by installing tar paper on top of the plywood. 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. The rise or height of the roof at its peak is the altitude of the triangle.
The framing of a basic gable roof is based on a right angle triangle and the various roof framing components fit the triangle. Once the trusses soffit and fascia are in place lay the roofing felt in place. Cut two rafters with a circular saw to the pitch of the addition roof and nail them across the rafters on the old roof. Nail the trusses into the existing room fasteners.
Step 3 prepare the materials. Adding pitch to a flat roof.
