Replacing hip or ridge cap shingles requires removing any damaged pieces that may have been left over. You may have to remove or loosen any shingles in the proximity of the blown-off shingle to allow you to re-fasten a new hip or ridge cap shingle.

Install the new piece; making sure it fully covers any existing ridge vent or other field shingles with the proper length fasteners. Utilize any asphalt cement as directed by the manufacturer’s application instructions.
Replacing hip or ridge shingles requires working on some of the highest parts of your roof—the hips and ridges. Always utilize proper safety equipment to prevent falls or injury when replacing hip or ridge shingles on your roof.
Deciding on the proper vent and the amount of ventilation needed is critical. Always consult your local building code for balanced attic ventilation requirements in your area.

Be careful not to cut any attic rafters or wires, and always ensure to properly fasten the vent to prevent blow-off or weather infiltration.
To find a leak source, you need to know what water is likely to do. Water will always flow directly down with gravity. Obstructions, skylights and penetrations are the most common leak sources. Start by examining chimneys, skylights, and plumbing vents. Then inspect roof-to-wall transition areas where flashing takes the place of roofing, such as dormers, valleys, and eaves.
