Robert Jones Posted August 25, 2013 Report Share Posted August 25, 2013 The pics are from a family member's roof. The shingles are only about 9-10 years old. I think their defective. Was there a shingle issue from the mid 2000's that I don't know about?

Was there a shingle issue from the mid 2000's that I don't know about? Rob Are you absolutely sure that those shingles are 9-10 years old? Shingles with fiberglass mats don't curl like that in our climate, but organic mat shingles do. The likelihood of 9-10 year old organic mat shingles is remote. Could be that those are just really old shingles doing what really old shingles do. Quote Link to comment Share on other sites More sharing options...
LeePlace Posted August 26, 2013 Report Share Posted August 26, 2013 Rob, With all the vents in the area of the cupping shingles, is there a cathedral ceiling underneath it? Lee Quote Link to comment Share on other sites More sharing options...
hausdok Posted August 26, 2013 Report Share Posted August 26, 2013 They didn't let a carpet of moss develop and remain on that cover for a loooonnggg time did the? OT - OF!!! M. Quote Link to comment Share on other sites More sharing options...
Tom Raymond Posted August 26, 2013 Report Share Posted August 26, 2013 That's exactly what 9-10 year old IKOs look like in my climate. Quote Link to comment Share on other sites More sharing options...
Chad Fabry Posted August 26, 2013 Report Share Posted August 26, 2013 That's funny, Tom. I was going to say the same thing except I was going add that there would be dozens of missing tabs if they were IKO's. Quote Link to comment Share on other sites More sharing options...
Robert Jones Posted August 26, 2013 Author Report Share Posted August 26, 2013 Thanks guys. Jim, I am positive on the age as they are the same age of the home. Mike, no moss buildup. Lee, no cathedral ceiling but a 1/2 story is there. My initial thought was heat and poor ventilation. Checked the attic, and there is no discoloration of the OSB sheathing or any other indication of poor ventilation. The home is a custom build and not in a development.

Jerry Simon Posted August 26, 2013 Report Share Posted August 26, 2013 If the damage was only on one or two of the roof elevations, I'd suspect hail-impact damage, resulting matting deterioration from sun's UV rays. Quote Link to comment Share on other sites More sharing options...

Strip 'em off and put on some Pabcos or Malarkeys. Quote Link to comment Share on other sites More sharing options...
hausdok Posted August 27, 2013 Report Share Posted August 27, 2013 If there isn't a severe moss/algae problem or a lot of tree debris remaining on the roof that gets wet and secretes tannic acid, I'd say it's a defect. I supposed it could be the IKO thing - they've got a manufacturing plant down near Olympia someplace and lots of local builders use their product, but I've seen plenty of IKO shingles here and they don't seem to have any issues .

Nolan Kienitz Posted August 27, 2013 Report Share Posted August 27, 2013 I've been digging through my Haag Engineering materials (used for the certified roof inspector class they have) and the images I noted in those books seem to indicate a manufacturing defect. Again, it could be a combination of things, but I would lean toward the defect approach. Quote Link to comment Share on other sites More sharing options...
