Havent used the TAMKO Heritage AR in a while! We used them today and there were more loose granuals coming out of these bundles then i have ever seen, it was Halariously Frightning on a 7/12, It was crazy, like a whole other roof was in the gutter when we finished.
I keep hearing of tis issue. The meat of the matter is whether or not it comes from excess granules being used to ensure full coverage of the shingles, or are they leaving voids or matt showing?
