John Kogel Posted March 27, 2012 Report Share Posted March 27, 2012 "Should we scrape off the moss?" "No, don't do that. At this point, the moss is holding the shingles on". [] Click to Enlarge 113.69?KB Click to Enlarge 122.68?KB Click to Enlarge 89.35?KB That was an easy one. This roof below was harder, It doesn't look too bad, except where the granules are gone off the ribs. I've seen this damage before and wonder if it is from scraping with a snow shovel? If so, it won't get worse for a while. But I wish I could be more specific on this one.

Erby Posted March 27, 2012 Report Share Posted March 27, 2012 The lines in the shingles are at about the same spot as the asphalt sticky spots on the shingle underneath. I doubt that comes from snow shoveling. Geeze, I'm glad I now live where I don't have to worry about shoveling snow off the roof! Quote Link to comment Share on other sites More sharing options...
Brandon Whitmore Posted March 27, 2012 Report Share Posted March 27, 2012 We don't have much snow shoveling activity on a roof around these parts, but still see that same deterioration on aged shingles that need to be replaced. Quote Link to comment Share on other sites More sharing options...
John Kogel Posted March 27, 2012 Author Report Share Posted March 27, 2012 Thanks, guys. I suppose wind does the scraping, hitting the high spots. Quote Link to comment Share on other sites More sharing options...
Jim Katen Posted March 27, 2012 Report Share Posted March 27, 2012 The buckles are occuring just above the seal strips. This is caused when the asphalt loses it malleability and is no longer able to accommodate thermal expansion and contraction. The shingles should have been replaced years ago.

Jim Baird Posted March 27, 2012 Report Share Posted March 27, 2012 In the last pics them shangles are just plain old and wore out. Quote Link to comment Share on other sites More sharing options...

AHI in AR Posted March 27, 2012 Report Share Posted March 27, 2012 I think the ridges visible in the shingles in John's second batch of photos are simply the edges of the layers of roofing underneath this one telegraphing through the roof.

Yes, sometimes that's it, but this was a one layer roof, I'm pretty sure. The upper edge of the first row seems to be visible in the exposed part of the third row. With some additional wrinkles. Thin shingles, no doubt. Quote Link to comment Share on other sites More sharing options...

Nope. If you use a probe or a screwdriver, you'll find that the tabs have buckles with nothing but air immediately beneath them. Quote Link to comment Share on other sites More sharing options...

Obviously weather conditions there are very different from my neck of the woods but I've never seen that condition. Maybe the shingles are formulated differently also.
