Recently many shingles have been blowing off the roof of my house. It appears as though the roofer placed many tiles along the peak of the roof, just stacking them on with a bit of roofing tar to hold them down. No other roof damage is happening and no leaks have occured.
My question is WHY did they just stack these on there without nailing them down? and why did they put som many on there.
My wife is in a panic because she thinks the roof is falling apart, but I don't think it is a big deal. I figure I will just go up there in the spring and stick them back on.
I imagine that the layer closest to the actual peak is nailed on and therefore the roof would be fine even if all those layers blow off.
Do roofers just put many layers on the top if they have the extra tile? or is there a real reason why they do that?
