How to Remove a Damaged Roof Shinglecomments (3) August 29th, 2011 in Blogs
BY STEPHEN HAZLETT
Some roof repairs—nail pops, for example—require replacing single shingles. Removing the damaged shingle without damaging the surrounding shingles is the tricky part. This process is best done while shingles are cool enough not to melt underfoot and warm enough not to crack. In the summer, I handle this part of the repair before 8 a.m. In the winter, I do only emergency repairs.
Step 1 Break the bond created by the seal-down strips below and on the two courses above the shingle you want to remove. Breaking this bond may be difficult with some newer laminated shingles. A 50-year shingle with a 110-mph wind warranty has an aggressive adhesive bond. In these cases, I cut the adhesive strip with a pry bar.
Step 2 With the bonds broken, I can remove the four nails holding the damaged shingle.
Step 3 Before I remove the shingle, though, I have to remove four more nails driven through the course above.
Step 4 Now I can pull out the damaged shingle, slip in a new shingle, and renail all the loosened shingles. When refastening shingles, don’t put new nails in the old nail holes; they’ll pop right out. Instead, nail next to the holes and put a dab of sealant over the old holes. While your caulk gun is handy, seal down all the loosened shingle tabs with a dab of sealant.
