The most common cause of a flat tire is puncturing of the tire by a sharp object, such as a nail, letting air escape. Depending on the size of the puncture, the tire may deflate slowly or rapidly.
My concerns with wet or damp felt is that it causes the felt to wrinkle. These wrinkles can hold up the shingles from laying flat till the moisture evaporates. This can be unsightly and disturbing to the home owner. In some cases, I have seen the roofer slice these wrinkles and not repair the felt properly.
