Shingles have a sealing strip between them. Many times, the wind will lift the shingles and break the sealing strip during a storm. After the storm, the shingles simply lay back down in place – looking fine. If that sealing strip is compromised, then your roof likely needs to be replaced. This sealing strip is critically important to the integrity, functionality, and longevity of your roof. If the sealing strip is compromised your roof will likely start leaking within a year or two of the wind event. That is why you need to have it examined immediately before it starts leaking.
Likewise, tile roofs suffer from a similar plight. The tiles themselves on a tile roof system are simply decorative. The water barrier for a tile roof is the underlayment – the paper below the tiles. In a strong wind, the wind can “chatter” the tiles on your roof. This means the wind gets up under the tiles and repeatedly “jiggles” them up and down during a storm. After the storm, the tiles look fine. However, during the storm, the chattering tiles have also “jiggled” the nails securing them to the underlayment causing the holes around the nails to open up wider than they should. This allows water to seep in around the nail holes throughout the roof. As with shingles, many times, the water damage does not begin to show up for a year or two from the wind event.
