I lost 2 ridge tiles last week in the high winds (middle 2 out of a row of 5 ridge tiles above bedroom). I had someone out to fix it today but am a bit concerned that the 2 new ridge tiles aren't sitting flush with the other existing tiles, they are sitting a bit higher (perhaps bigger than the gap left by old ones). When i asked the roofer if they were bigger tiles he said they were and that its hard to get the exact same size as a lot of tiles are discontinued. My house is only 9 years old. He has put fresh cement on to bed them in. I'm concerned that if we get high winds again they will blow off. Does it sound like a botch job or could he be telling the truth?
