• Cut a slit in the existing roofing material above the damaged area.
• Slide the new piece of material into the slit.
• Hold the slit edge and remaining edges of the new roofing material up; apply cold tar or roof cement, and press the edges down.
• Nail the edges.
• Cover the nail heads and edges of the patch with roofing tar or sealer.
