Start by removing any damaged material, confirming the underlayment and decking are sound, and cutting the patch to fit flush with surrounding shingles.

After patching the hole and installing a replacement underlayment if needed, slide replacement shingles into place following the original exposure and the roof slope. Match the woven pattern where applicable by alternating courses so seams do not line up vertically; this improves water shedding. Use new roof nails of the correct length so they penetrate the shingle, the roof felt, and at least three quarters of an inch into the decking without overdriving them. Place nails away from any new seams and at least one inch above the shingle cutout line so the flap covers the fasteners when the next course is installed. Bed the tabs with a small bead of roofing cement under any cut edges or where the patch meets adjacent shingles to seal gaps and prevent wind lift. Finally, press the sealant into place, lift the tab to check alignment, and add a dab of cement over the nail heads that sit near exposed edges to prevent water entry.

Common problems are misaligned exposure, which creates vertical seams and leaks; fix this by measuring the remaining exposure from the course below and set each replacement to that same reveal so seams offset naturally. Another frequent issue is using old nails or nailing too close to cut edges, which causes split shingles or back-out; always use fresh nails and position them in the prescribed nailing zone one inch above the cut line to avoid splits and ensure proper holding. The third is failing to reseal cut edges and nail heads, allowing water to infiltrate; apply small beads of roofing cement under lifted tabs and over exposed fasteners, then press firmly to compact the seal without smearing excess.
