When you guys are doing roof repairs, how picky are you on doing repairs under the allowable? If there is an active roof leak and it can be fixed under $600, that makes sense. Also, any missing shingles, replace on the spot. How about tar around chimney or vents that looks very old and cracked, but no noticeable leaks? How about improperly installed(or missing) drip edge? Do you guys still repair them if they aren't causing an active leak?
