I just had a new roof put on and my wife and I noticed that there are some sections of shingle that show tar like if too much tar was used. Can this be fixed?

A picture would be helpful – Steven Jul 17 '13 at 23:55
Agreed, a photo would be useful. It sounds almost like they spaced the rows too far apart so the adhesive tar strip is showing. – BMitch Jul 18 '13 at 1:27
I don't believe any tar is used when putting shingles on a roof (except for the tar already in the shingles), so you can't have "too much". – Henry Jackson Jul 18 '13 at 1:38

Asphalt shingles have strips of tar on them that are designed to be covered by the next layer of shingles. The top shingle will heat up, melt the tar strip, and then that tar strip will grab onto the shingle above, and so it helps stabilize the shingle in place.

Is that what you're seeing?

when I take off roof jacks, I dab tar on the nail heads. I've also dabbed tar under flaps on sides with know wind problems, such as harbor front exposures. But none of this ever 'shows'. – mike Aug 17 '13 at 15:36
