The roof is approximately 5 years old and I called out the fact that they used architectural shingles on the ridge(that were flipping up of course) rather than three tab or ridge cap shingles. Here was the response to the buyer. "4. Regular shingles are commonly cut and installed on the ridge. The inspector himself estimates AT LEAST 10 more years of life left on the roof. The shingles are either 30 or 40 year shingles. Therefore, these shingles on the ridge have been doing the job they were installed to do for a long time, through many high winds and not one has blown off. In fact, the asphalt strip on the back, meant to melt down and adhere one shingle to the next has done just that, and pulling them off now may damage the rest of the roof they are adhered to. These shingles are not a problem. The inspector says the roof is watertight, Best to leave well enough alone."
