I just purchased a ranch house. During the home inspection, the inspector mentioned to me that the shingles on the roof are close to the end of their life span. My agent assured me that I may squeeze five more years out of the roof if I replaced the few missing shingles.
This Friday, when I was attempting to climb onto the roof, I happened to notice the valley on the front roof is in bad shape, if not shot already. I could barely see the aluminum underlay and the rotted shingle remnants (please see photos in the link below). I surmise that when they put the 2nd layer on the existing roof, they may skip the valley or did a poor job. It is hard to observe on the ground unless you climb on the roof and inspect there. Does this finding implies that I have to budget for a tear off re-roof or is it still fixable by a reputable roofer? How much does it cost for the replacement or repair? Thanks in advance for all your insightful input.
